WCO – Strengthening Customs Business Partner Relationships in the SACU Region

CP Mission 16_01_465_ Successful Stakeholders Training

During November 2016, 16 Customs officers from SACU member administrations received training in the area of successful stakeholder consultation. The training was facilitated by Accredited WCO Experts from the SACU region. As a result of the workshop, participants drafted National Stakeholder Consultation action plans which outline the administration’s national effort in necessary interaction with key stakeholders. The action plans will be used to guide and improve cooperation with businesses in the implementation of the Preferred Trader Programme once they are approved by the Member administrations.

Trade Facilitation Agreement enters into force

wto-tfa-enters-into-force

Trade Facilitation Agreement, 22 February 2017.

A major milestone for the global trading system was reached on 22 February 2017 when the first multilateral deal concluded in the 21 year history of the World Trade Organization entered into force. In receiving four more ratifications for the Trade Facilitation Agreement (TFA), the WTO has obtained the two-thirds acceptance of the agreement from its 164 members needed to bring the TFA into force.

Rwanda, Oman, Chad and Jordan (pictured above) submitted their instruments of acceptance to WTO Director-General Roberto Azevêdo, bringing the total number of ratifications over the required threshold of 110. The entry into force of this agreement, which seeks to expedite the movement, release and clearance of goods across borders, launches a new phase for trade facilitation reforms all over the world and creates a significant boost for commerce and the multilateral trading system as a whole.

Full implementation of the TFA is forecast to slash members’ trade costs by an average of 14.3 per cent, with developing countries having the most to gain, according to a 2015 study carried out by WTO economists. The TFA is also likely to reduce the time needed to import goods by over a day and a half and to export goods by almost two days, representing a reduction of 47 per cent and 91 per cent respectively over the current average.

Implementing the TFA is also expected to help new firms export for the first time. Moreover, once the TFA is fully implemented, developing countries are predicted to increase the number of new products exported by as much as 20 per cent, with least developed countries (LDCs) likely to see an increase of up to 35 per cent, according to the WTO study.

At present, 10 out of 24 Members of East and Southern Africa (ESA) have ratified the TFA. These are; Mauritius, Botswana, Lesotho, Kenya, Zambia, Seychelles, Madagascar, Swaziland, Mozambique and Rwanda. So where to now South Africa?

Australian Narcotics bust – the significance of NII

The Australian Border Force reports that four men have been arrested in Sydney and Melbourne for allegedly importing approximately 254kg of cocaine and 104kg of methyl-amphetamine into Australia.

Combined, the drugs had an estimated combined value in excess of $186 million.

An Australian Federal Police (AFP) investigation commenced in December 2016 after the Australian Border Force (ABF) targeted a cargo consignment containing mining equipment which had arrived in Melbourne from South Africa.

ABF officers at the Melbourne Container Examination Facility examined the consignment which included industrial mining equipment. X-ray images revealed anomalies within an iron ore extractor.

It will be alleged that a physical examination of the iron ore extractor by ABF officers led to the discovery of 358 1kg block packages of cocaine and methyl-amphetamine, concealed within the equipment among a load of activated charcoal.

On 19 December 2016, the AFP commenced a controlled delivery where the consignment was delivered from Melbourne to a storage facility in Sydney.

Three men were arrested after accessing the consignment in Sydney on Sunday, 5 February 2017.

During additional search warrants on Monday, 6 February, 2017 on the Central Coast of NSW, AFP officers also seized a large sum of cash in a compressed block of AUD$100 notes. The notes are currently the subject of further forensic analysis.

A fourth man was arrested in Melbourne on Wednesday, 8 February 2017.

A 47-year-old (Watanobbi) man and 75-year-old male South African citizen were charged with:

  • One count of attempt to import commercial quantities of border controlled drugs, pursuant to subsection 307.1 (1), by virtue of subsection 11.1 of the Criminal Code 1995 (Cth) and;
  • One count of attempt to possess a commercial quantity of border controlled drugs, pursuant to subsection 307.5 (1), by virtue of subsection 11.1 of the Criminal Code 1995 (Cth).

A 39-year-old (Doonside) man was charged with:

  • One count of attempt to possess commercial quantities of border controlled drugs, pursuant to subsection 307.5(1) by virtue of subsection 11.1 of the Criminal Code 1995 (Cth).

A 38-year-old (Roxburgh Park) man was charged with:

  • One count of import commercial quantities of border controlled drugs, pursuant to subsection 307.1 (1) of the Criminal Code 1995 (Cth).

The maximum penalty for these offences is life imprisonment.

AFP Commander John Beveridge said the AFP and its partners are committed to protecting the Australian community from the scourge of illicit drugs through targeted detection and disruption.

“The AFP will continue to work with its partner law enforcement agencies to disrupt all forms of drug importation attempts and target those who believe they are above the law,” Commander Beveridge said.

“These arrests send a strong message to criminals who choose to import harmful drugs into our community for their own profits – you will be caught, no matter how creative you believe your concealment method may be.”

ABF Regional Commander Victoria and Tasmania, James Watson, praised ABF officers at the Melbourne Container Examination Facility for the outstanding detection.

“Our officers have the expertise and technology to detect even the most sophisticated concealment. In this instance, our upgraded container x-ray technology has been able to penetrate through several layers of steel, machinery and coal/stones to identify these concealed packages.

“The success of this operation once again highlights how effectively Australia’s border and law enforcement agencies are working together to stop illicit drugs from entering our community, and how instrumental the ABF is in keeping these dangerous drugs off our streets.”

Three men appeared before Sydney Central Local Court on Monday, 6 February 2017 where they were remanded in custody.

A fourth man appeared before Melbourne Magistrates Court on Wednesday, 8 February 2017 where he was remanded in custody to re-appear on 10 February 2017 for a filing hearing. Source: Border.gov.au

ICD 2017 – Observing effective Border Management through ‘data analysis’

wco-icd2017As national Customs administrations and border agencies celebrate International Customs Day, no doubt showcasing their recent ICT endeavours, it is good to reflect not only on the available standards and tools which are becoming more available to Customs and Border Management Agencies.

The WCO spearheads and supports several initiatives aimed at fostering increased coperation and collaboration between member states under the banner of ‘Digital Customs’. In the post security era, throught is capacity building arm, the WCO champions global development of its Digital Customs concept and strategy. The WCO’s work programme in this regard covers a broad area of focus, for example:

  • to support the WTO Trade Facilitation Agreement,
  • the updating of related WCO instruments and tools,
  • ongoing promotion and maintainance of the WCO Data Model,
  • monitoring of new and emerging technological developments (3D printing, Big Data, Predictive Analytics, Drones and Blockchain),
  • promotion of e-services and apps,
  • exchange of information between stakeholders nationally and accross borders, and
  • promotion of the Single Window concept.

For most customs and border administrators, they have somewhere heard of, or to some extent are aware of the ‘buzz words’. The various chapters of the WCO through the working groups provide up-to-date developments in all facets on developments in the modern Customs operating and global trade environment. These are ably supported by several internal business organisations and umbrella associations adding credence to the developmental work and ultimately the standards, policies and guidelines published by the WCO.

In this modern era of uncertainty – global political and socio-economic risks – International Customs Day should be a combined celebration not only for Customs, but moreover, the associated supply chain industries and business intermediaries. If there was no trade in goods there would be no Customs or WCO. Without the providers of ‘big data’ there would be no need for data analysis. Without illicit activities there would be no need for expensive enforcement technology and equipment and the application of risk management.

Thanks to an imperfect and unequal world the WCO, through its association with the world’s customs authorities, big business and ICT service providers is able to develop a Digital Customs Maturity Model, which provides a road map for administrations from the least to most developed (mature rather). The pace and extent of maturity is undoubtedly determined by a country’s discipline and agility based on a clear strategy with the support and commitment of government and allied industries.Happy Customs Day!

Zim Revenue Scourge – porous borders lose millions

cigarettes

The Zimbabwe Herald suggests that Zimbabwe could be losing millions of dollars in unpaid taxes due to rampant smuggling of cigarettes into South Africa, investigations by this paper have revealed.Between 2014 and 2015, local customs officials seized nearly 2 500 cartons worth around $500 000 in taxes, according to the Zimbabwe Revenue Authority.

Figures from the South African side are staggering, showing a wide discrepancy in the value of confiscated contraband between the two neighbouring southern African countries.

The South African Revenue Service told The Herald Business that it had seized R87 million (US$6,2 million) worth of Zimbabwean cigarettes since 2014, or 95 million sticks.

This will likely be worth millions of dollars in evaded tax in Zimbabwe, but the ZIMRA director for legal and corporate services Ms Florence Jambwa said the figures were difficult to determine because smuggling was an underground trade.

South Africa, however, says it loses an estimated R40 million (US$2,9 million) to cigarette smuggling each year, on the average, more than half of it Zimbabwe-related.

And this is just from what is on public record. Customs officials from both countries admit the figures could be higher. Both are also greatly incapacitated to detect illegal trades quickly.

“It is difficult to measure the levels of smuggling as this is an underground activity mostly done through undesignated entry points,” said ZIMRA’s Jambwa, by email.

“The value of the potential loss cannot be easily ascertained,” she said, failing to provide an estimate.

Tax analyst Mr Tendai Mavhima said the figures from ZIMRA represent only a small portion of the actual amount of money Zimbabwe is losing to trafficking of cigarettes.

“The disparity in figures (ZIMRA and SARS figures) indicate there are problems in controls on either side, which may result in the revenue and tax losses from both countries being understated,” he said by telephone.

Zimbabwe is the world’s fifth largest producer of tobacco after China, the USA, Brazil and India.

The country produces flue-cured Virginia tobacco, considered to be of extremely high quality and flavour, according to a report on Zimbabwean tobacco companies by local stockbroking firm, IH Securities.

As such, Zimbabwean tobacco ends up in many top cigarette brands across the world, it says.

It is especially popular in China, the largest importer of Zimbabwean tobacco, and in South Africa, the country’s largest trading partner.

In South Africa, Zimbabwean cigarettes are on demand for two key reasons: high quality and affordability.

It costs just $1,50 for 20 sticks in Zimbabwe compared to $3,20 for the same number of sticks in South Africa, according to estimates by regional economic bloc, SADC.

The South African Revenue Service (SARS) said: “Cigarette clientele opt for cheaper cigarettes. The high supply and demand for illicit cigarettes creates the market for it.”

South Africa imposes very high taxes on cigarette imports – about 80 percent meaning many Zimbabwean dealers choose to export illegally.

SADC says illegal dealers supply nearly two thirds of the number of cigarettes smoked by South Africans.

In 2011 alone, at least 4 billion cigarettes smuggled into South Africa originated from Zimbabwe, it says.

The undeclared cigarettes are usually concealed in trucks, buses and other vehicles destined for South Africa by organised cartels, said Florence Jambwa of ZIMRA.

WCO – the opportunities and challenges of E-commerce

wco-in-russia

The WCO Policy Commission, held in Moscow, Russian Federation, from 5 to 7 December 2016 under the chairmanship of Mr. R. Davydov, brought to the fore the key role of Customs in creating a sustainable and efficient e-commerce ecosystem, reviving-up the exchange of data between stakeholders and enhancing risk-management through electronic interface. The other main topics discussed during the Commission pertained to trade facilitation, security, the enhancement of the Customs/Tax cooperation and the modernization of Customs administrations.

The newly established WCO Working Group on E-Commerce will work to tackle the different dimensions of e-commerce by collecting and exchanging best practices in the field, stocktaking and leveraging some of the ongoing work being carried out by other entities and drawing up proposals geared towards the development of practical solutions for the clearance of e-commerce shipments, including appropriate duty/tax collection mechanisms and control procedures.

Concerning the in-depth discussions on Custom /Tax cooperation, the WCO issued this year “Guidelines for strengthening cooperation and the exchange of information between Customs and Tax authorities at the national level” and will continue working on topics of common interest for Customs and Tax experts such as transfer pricing, drawback and Illicit Financial Flows (IFF).

During the Commission, WCO Secretary General Kunio Mikuriya, confirmed the WCO Theme for 2017 “Data Analysis for Effective Border Management” and stressed the impact of the digital revolution and the need to address promptly the challenges posed to the global economy. The Secretary General invited all the WCO Members to promote and share information in the coming months on how they are leveraging the potential of data to advance and achieve their objectives and respond to the expectations of traders, transport and logistic operators, and governments.

As data analysis will be emphasized in 2017 as a force multiplier for Customs administrations, it is relevant to highlight that the WCO is carrying out a Study to collect best practices among its members to assess and promote initiatives in the area of e-commerce. A previous analysis of preliminary data underscored the need for digitalization of processes, better sharing of information between e-commerce stakeholders and customs for improved risk management and the necessity for harmonization in the low-value shipment processes.

China Customs – pilots Independent Customs Declaration and Tax Payment for Imported Goods

China Customs EmblemAudit firm KPMG reports that the General Administration of Customs (GAC) will reform the existing customs clearance procedure for imported goods, according to a GAC Circular on Carrying out Pilot Reform of Tax Collection and Administration Procedure issued on 29 October 2016. Under the current procedure, review of the customs declaration is required before goods are released. This reform is designed to further guide import and export enterprises to be self-disciplined and law-abiding, with the principle stated as “honesty and observance of the law brings convenience; dishonesty and irregularity leads to punishment” to improve customs clearance efficiency.

Content of pilot reform  includes the following elements:

Independent customs declaration and tax payment – when importing goods, enterprises should submit customs declarations truthfully and accurately in advance, calculate tax payable and surcharges and handle payment-related procedures on their own.

Review of elements relating to tax calculation after release of goods  – generally, goods will be released after enterprises complete the customs declarations and tax payment procedures on their own. Afterwards, the customs authority will spot-check and review the valuation, classification and origin of the imported goods of the enterprises. In special cases, the authority will inspect the customs declaration in advance.

Proactive disclosure scheme After release of goods – enterprises are encouraged to report to the authorities in writing if they are aware of any of their own violations against customs regulations. Enterprises which the customs authority believes to be voluntary disclosers of their own irregularities will be less punished or free from punishment. For enterprises which have disclosed their irregularities and paid back taxes proactively, late fees can be reduced or eliminated.

International Shipping Federations take on Counterfeit Goods Trade

bascap

Leaders from global shipping firms, freight forwarders, brand owners whose products are counterfeited and industry organizations representing both industries signed a joint Declaration of Intent to Prevent the Maritime Transport of Counterfeit Goods in Brussels last week.

The event marked the first time the global shipping industry and brand owners have made a public commitment to work together to stop the transport of counterfeit goods on shipping vessels.

Initial signatories include the leading global shipping firms and freight forwarders and ten major multinational brand manufacturers, along with the International Federation of Freight Forwarders Associations (FIATA), and the International Chamber of Commerce’s (ICC) Business Action to Stop Counterfeiting and Piracy (BASCAP) and Commercial Crime Service (CCS).

More transporters, brand owners and their industry associations are expected to join the voluntary initiative as awareness grows.

According to the United Nations Office on Drugs and Crime, about 90 percent of all international trade is moved around the world in more than 500 million containers on 89,000 maritime vessels. While this represents approximately 90 percent of all international trade, UNODC says that less than two percent of these containers are inspected to verify their contents. This results in enormous opportunities for criminal networks to abuse this critical supply chain channel to transport huge volumes of counterfeit products affecting virtually every product sector.

According to a recent OECD/EUIPO report, $461 billion in counterfeit goods moved through international trade in 2013, with almost 10 percent being shipped on maritime vessels.

Maersk Line and CMA CGM Group, two of the largest global transport companies with approximately half of all global shipping, and Kuehne and Nagel and Expeditors, two of the leading freight forwarding and logistics companies with total revenues of more than $27 billion, were the first in their industries to sign the Declaration.

The non-binding Declaration acknowledges the “destructive impact” of counterfeits on international trade. It calls on the maritime transport industry to address it “through continuous proactive measures, and corporate social responsibility principles.” The Declaration includes a zero tolerance policy on counterfeiting, strict supply chain controls and other due diligence checks to stop business cooperation with those suspected of dealing in the counterfeit trade.

This commitment paves the way for new voluntary collaboration programs between intermediaries and brand owners to stop abuse of the global supply chain by counterfeiters.

“We are proud to be among the first in our industry to sign this historic Declaration,” said Michael Jul Hansen, Customs and Trade Compliance Lead for Maersk Line. “Maersk has been a leader in taking steps to prevent the use of our vessels for the shipment of counterfeit and other illicit goods, and this Declaration is a reaffirmation of our intent to do everything we can to ensure our ships are counterfeit free.”

The Declaration is a direct reaction to the concerns of brand owners that vessels transporting their legitimate products were also being exploited by criminal networks to transport fake versions. This phenomenon was summarized in a landmark report on the Role and Responsibilities of Intermediaries: Fighting Counterfeiting and Piracy in the Supply Chain, published in 2015 by BASCAP. Following publication of the report, BASCAP organized a working group of its members to initiate a cross-sector dialogue with the transport industry to discuss ways to work together to find voluntary solutions.

WCO declares 2017 to be the year of Data Analysis

wco-icd2017The Secretary General of the WCO, Kunio Mikuriya, announced today that 2017 will be dedicated to promoting data analysis under the slogan “Data Analysis for Effective Border Management.” WCO Members will thus be called upon to further promote their efforts and initiatives in a sector that is becoming a key element in Customs modernization process: collecting and analysing data.

Customs has a substantial amount of data at its disposal, such as data submitted for the Customs clearance process. Customs can also tap data from other government agencies, commercially available databases, and open source information platforms such as digitized global public records and multilingual news sources.

Moreover, physical objects are nowadays embedded within electronics, software, sensors and network connectivity, which enables these objects to collect and exchange data, a phenomenon known as the ‘Internet of things’.

Simply collecting data for its own sake, however, is not sufficient and Customs administrations may face the risk of being overwhelmed with an avalanche of data. Data only has value when it is used effectively and efficiently. It is critical, therefore, that Customs administrations leverage data to make informed decisions, especially given the sophisticated and evolving challenges that Customs administrations face every day.

Data analysis can propel Customs to new levels of success in both compliance and facilitation, by enabling it to:

  • improve risk management which supports enhanced detection of irregularities, illicit consignments, the suspicious movement of people and financial flows, and the facilitation of legitimate trade;
  • learn from historical activity to predict trader or passenger behaviour;
  • engage with other government agencies to leverage their experience and expertise;
  • conduct quantitative research for purposes of building knowledge;
  • enhance performance measurement to improve officer practices and integrity. Data analysis thus can greatly support the core Customs’ objectives of revenue collection, border security, collection of trade statistics, and trade facilitation.

“To achieve these benefits, Customs administrations should make data analysis a strategic priority and acquire cutting-edge technology, establish appropriate automation policies, and recruit experts to collect and analyse data, and act upon the data-driven insights”, said WCO Secretary General, Kunio Mikuriya.

There are of course potential obstacles to an optimal use of data, such as the lack of qualitative data, data that has not been integrated or merged, lack of harmonization of data across border agencies, lack of skilled resources, IT infrastructures and cultural challenges. In addition, it is vital that appropriate privacy and confidentiality laws be respected.

“Data analysis and related challenges will be thoroughly discussed within the WCO during 2017, and at events such as the Information and Technology Conference, the Global Conference on Transit, and the Technology and Innovation Forum”, Dr. Mikuriya added.

As part of this initiative, the WCO will enhance the promotion of tools such as the WCO Customs Enforcement Network (CEN) which is a global Customs seizure database; the WCO Time Release Study (TRS) which is a methodology for measuring border agency clearance times; mirror analysis which involves using the HS Code to compare imports (or exports) of a country with exports (or imports) reported to the country by its trading partners to detect gaps in terms of quantities, weight or value that may reveal fraudulent flows or practices; the use of performance measurement to improve Customs procedures and integrity, such as through the techniques presented in the WCO Performance Measurement Contracts Guide; and the Data Model which supports data analysis by improving data collection and enabling the sharing of data between government agencies.

The WCO’s annual theme will be launched on International Customs Day, which is celebrated annually by the global Customs community on 26 January in honour of the inaugural session of the Customs Co-operation Council (CCC) which took place on 26 January 1953.

The WCO invites the Customs community to mark 26 January 2017 in their diary. Source: WCO

SARS Management benefits from the WCO LMD Workshop

wco-lmd

As part of its Capacity Building programme, the WCO organized a Leadership and Management Development (LMD) workshop from 14 until 25 November 2016 in Pretoria, South Africa. Nineteen middle managers of the South African Revenue Service (SARS) were inspired to strengthen their leadership and management capacities, as well as their personal effectiveness to drive reforms within their organization. The workshop was made possible with the support of the Finnish Ministry of Foreign Affairs.

During a meeting with a delegation of executive management at the end of the LMD workshop, participants were invited to not only implement their newly acquired skills and insights in their own units, but to also continue learning and developing themselves as well as the whole organization. A first follow-up meeting to that end was immediately planned.

In the LMD workshop participants learned that knowing yourself and self-awareness, managing strategically, people management, outstanding communication skills and change management are very important to address SARS’ future challenges. The participating managers were extremely participative and showed a strong motivation and commitment to know, improve and manage themselves, in order to have a great and positive impact on others, as well as on the organization. With personal testimonies at the end of the workshop participants demonstrated their motivation to bridge the gap between policy making and organization-wide implementation of changes.

In the near future SARS will implement its own Leadership and Management Development programme. For further development as a regional centre of expertise in this LMD domain SARS and WCO plan to strengthen their cooperation.

Why dogs’ noses out-sniff the most advanced bomb detectors

detector-dog-fotorezekne-depositphotos

In 2010, after spending six years and $19 billion on research to develop better bomb detecting technology, Pentagon officials admitted that dogs’ noses were still superior to their most sophisticated technology. Now scientists say the reason for this might lie simply in the way they sniff.

In her book Inside of a Dog, Alexandra Horowitz, an assistant of psychology at Barnard College, offers an analogy to show just how powerful a dog’s sense of smell is: while we might be able to tell if a teaspoon of sugar has been added to our coffee, place the same amount in a million gallons of water (roughly the equivalent of two Olympic-sized pools) and a dog would most likely be able to detect it.

This ability to single out and pick up even the faintest of odors is what makes dogs invaluable as bomb detectors. They can detect trace explosives in crowded settings such as airports and public transit areas, as well as odorless chemicals like TNT.

However training pooches to be effective bomb detectors is expensive and time-intensive. While all dogs have a superior sense of smell, not every breed is trainable. Hence the on-going quest to develop an e-nose that can equip bomb detectors with the canal physiology of dogs.

In the latest development in this arena, researchers at the National Institute of Standards and Technology (NIST), the Massachusetts Institute of Technology’s Lincoln Laboratory and the US Food and Drug Administration have found that the way a dog sniffs could shed light on how to improve trace detection capabilities.

While we don’t differentiate between breathing and smelling, a dog, with its far more complex nasal system, treats them as two separate functions. According to Matt Staymates, a mechanical engineer at NIST, apart from having a complex olfactory system, the key to what makes dogs so good at sniffing out bombs is, well, in its sniff. This is a two part-process and key to this is what happens when it exhales.

Breathing and smelling are treated as two separate functions in a dog’s nose. When it inhales, the air is channeled into two different paths and when it exhales, the air exits through the sides of its nose so that the exiting air doesn’t interfere with its ability to smell. As counterintuitive as it might sound, when it exhales, the outgoing air jets “entrain—or draw in—vapor-laden air toward the nostrils. During inhalation, the entrained air is pulled into each nostril.”

detector-dog-fotorezekne-depositphotos2

Using a 3D model of a Labrador retriever’s (one of the most commonly used breeds in bomb detection) nose to mimic how dogs sniff, and together with the help of schlieren imaging – a technique used for imaging the flow of air around objects – and high-speed video, Staymates and his team were able to confirm the above conjecture.

In their first set of experiments, they found that compared with trace-detection devices that rely on continuous suction, the artificial dog nose was four times better 10 cm (3.9 inches) away from the vapor source and 18 times better at a stand-off distance of 20 cm (7.9 inches).

When they integrated it with a commercially available vapor detector, the switch, which enabled it to sniff like a dog rather than inhale in its standard 10-second intervals, improved its ability to detect odors by a factor of 16 at a stand-off distance of 4 cm (1.6 inches).

This research team is not the first to study how the canine sniffing abilities can be used to develop a better bomb detector. In 1997, the Defense Advanced Research Projects Agency launched the Dog’s Nose program for this purpose. One of the technologies to emerge from it was a chemical explosives detector called Fido, which was modelled after the canine nasal physiology.

However while there have been various attempts to develop a canine e-nose over the years, the results, while promising, have not yet resulted in a breakthrough for the industry. Reliability as well as the ability to detect things at a distance remain a challenge and while this latest study confirms yet again the dog’s remarkable olfactory prowess, it is “just a piece of the puzzle,” as Staymates notes. “There’s lots more to be learned and to emulate as we work to improve the sensitivity, accuracy and speed of trace-detection technology.” Source: National Institute of Standards and Technology NIST
