Trade & Customs Watch is our weekly briefing on the customs, tariff and trade-regulatory developments that matter to businesses moving goods across borders and to the administrations that control them. Each item is drawn from the primary record and linked to it, with a short note on what it means in practice.
The week in brief
Viet Nam’s amended Customs Law was published this week, giving smart customs, the National Single Window and the customs treatment of e-commerce goods a statutory footing from 1 March 2027. HMRC issued two trade remedies notices in quick succession: a provisional anti-dumping duty on glass containers from China, and a five-year extension of the anti-dumping duty on Chinese wire rod. The UK’s call for evidence on modernising the customs regime closed on 15 September, leaving the consultation on mandatory registration of customs intermediaries as the last open window, closing on 21 September. And the World Customs Organization published two items that speak to how modern border control is organised: the Secretary General’s visit to Kazakhstan, framed around the digital Middle Corridor, and the results of Operation COLIBRI ZAFIRO, a nineteen-country enforcement operation against general aviation crime.
Viet Nam: amended Customs Law takes effect on 1 March 2027
National Assembly of Viet Nam, Law No. 11/2026/QH16, published 11 September 2026. The amended Customs Law, passed by the National Assembly on 23 August 2026 and published on 11 September, takes effect on 1 March 2027. It provides a legal basis for digital and smart customs systems and for the National Single Window; introduces a new Article 16a bringing goods traded through e-commerce platforms within customs procedures, with platform operators responsible for electronic identification and authentication; permits bonded warehouses and cargo consolidation points in free trade zones, logistics centres and industrial clusters; gives customs a power to suspend transit goods where there are clear grounds to suspect intellectual-property infringement; replaces a number of prior-approval procedures for goods under customs supervision with a notification requirement; and frames compliance management around the declarant’s compliance history and risk profile. The text of the law is available in Vietnamese; an English summary was published by Vietnam Investment Review on 11 September.
What it means. Primary legislation sets the frame, but the operating detail will arrive in implementing decrees and circulars over the next eighteen months, and that is where importers, exporters, logistics operators and e-commerce platforms doing business in Viet Nam should focus their attention. Platforms in particular acquire a defined role in customs control for the first time, and bonded and consolidation operations become possible in locations previously closed to them, which changes the economics of regional distribution models. For administrations elsewhere, the law is a useful example of a customs code being rewritten around risk-based, history-based compliance and a statutory single window rather than around uniform physical control; the test, as always, will be whether the risk engine, the single-window integration and the workforce are ready by the effective date.
UK: provisional anti-dumping duty on glass containers from China
HMRC, Trade Remedies Notice 2026/25, published 8 September 2026, effective 9 September 2026. HMRC has given effect to a provisional anti-dumping duty on certain glass containers originating from China, covering carboys, bottles, flasks, jars, pots, phials and preserving jars used for the conveyance or packing of goods, across fifteen UK Global Tariff commodity codes in the 7010 90 series. Ampoules, tubular glass containers, containers of 2.5 litres or more and standalone closures are excluded. The provisional rates are 26.87 per cent for the Huaxing Group, 24.65 per cent for the SPG Group, 25.88 per cent for non-sampled co-operating exporters and 52.97 per cent for all other exporters. The measure applies for a maximum of six months or until definitive measures are implemented, whichever is sooner, and importers must provide security in the form of a bank guarantee, bond or cash deposit equal to the estimated duty; the guaranteed amount becomes payable only if definitive measures are imposed. The notice is published on GOV.UK.
What it means. Importers of glass packaging, and the food, beverage, cosmetics and pharmaceutical businesses that depend on it, should check their supplier base against the named exporter groups now, because the difference between a co-operating exporter rate and the residual rate is more than twenty-five percentage points. A provisional duty secured by guarantee rather than paid outright is a cash-flow and documentation question as much as a cost question: the security has to be in place at import, and the exporter identity on the commercial documents determines which rate the guarantee is calculated on. The registration notice issued earlier in the year for these goods should also be reviewed, since it bears on whether definitive duty could be applied retrospectively to imports made during the registration period.
UK: anti-dumping duty on wire rod from China extended to 2031
HMRC, Trade Remedies Notice 2026/26, published 10 September 2026, effective 11 September 2026. Following a transition review, the anti-dumping duty on hot-rolled bars and rods in irregularly wound coils of iron, non-alloy steel or alloy steel other than stainless steel, originating from China, is extended for a further five years to 28 January 2031. The rate is 7.9 per cent for the Valin Group and 24.0 per cent for all other overseas exporters. The lower rate is available only where the goods are accompanied by a valid commercial invoice carrying a signed declaration from an official of the invoicing entity, stating that the goods were produced by the named company with the relevant additional code and that the information in the invoice is complete and correct. The notice is published on GOV.UK.
What it means. Read together with the glass-container notice, this is a clear illustration of how the UK trade remedies regime operates at exporter level: exporter-specific rates, a residual rate for everyone else, and access to the lower rate conditional on documentation that customs can check at the border. For importers of wire rod, the practical point is that the invoice declaration is not a formality; a missing or defective declaration converts a 7.9 per cent liability into a 24.0 per cent one, and post-clearance audit can revisit the entry. Steel importers should also note that the measure now runs to 2031, so sourcing and pricing assumptions built on an expiry in 2026 need updating.
UK: customs modernisation call for evidence closes; intermediaries consultation closes on 21 September
HMRC and HM Treasury, 23 June to 15 September 2026; HMRC, 23 June to 21 September 2026. The call for evidence on modernising the UK customs regime closed on 15 September. It sought views on three themes: how international trade patterns and digitalisation are changing what is asked of the customs system; whether current declaration data requirements fit the way business now operates, including the role of supply-chain data, electronic trade documents and interoperability standards; and whether the UK’s approach to customs authorisations and trusted-trader status supports a modernised trading environment. The government has said it will aim to publish a summary of responses within twelve weeks of closing. The separate consultation on mandatory registration for customs intermediaries, covering the scope of registration, which intermediaries should be included or excluded, the proposed mandatory requirements and checks, and the approach to enforcement, remains open until 11.59pm on 21 September 2026.
What it means. The authorisations question is the one with lasting consequences. A summary of responses due around mid-December will be the first public signal of whether the UK intends to preserve, simplify or reshape the authorisation and trusted-trader architecture it inherited, and businesses holding or seeking authorisations should plan for that signal rather than for the status quo. On intermediaries, the remaining days of the consultation are the last opportunity to influence the scope and minimum requirements of a statutory register; brokers, forwarders and any trader that submits declarations for others should consider whether the proposed scope captures them and what the registration checks would require of their business. Administrations elsewhere considering broker licensing may find the UK’s sequence, from a published standard to a voluntary scheme to a statutory register, worth studying.
WCO: customs digitalisation and the Middle Corridor in Kazakhstan
World Customs Organization, 14 September 2026. The WCO Secretary General, Ian Saunders, met the President of Kazakhstan, the Prime Minister, the Minister of Finance and the Chairman of the State Revenue Committee, and received briefings on the KEDEN integrated customs system, which delivers electronic declaration, advance information and digital transit. The Secretary General affirmed WCO support for the customs dimension of the Trans-Caspian International Transport Route, the Middle Corridor, and said that international standards, including the WCO Data Model, the SAFE Framework of Standards, the Harmonized System Convention and the Revised Kyoto Convention, provide the common language needed for the end-to-end digital corridor Kazakhstan envisages, while noting that sustained local effort and coordination with neighbouring administrations remain essential. The release is published by the WCO.
What it means. The Middle Corridor has become the most closely watched overland alternative between China and Europe, and its value to shippers depends less on infrastructure than on whether customs data can travel ahead of the goods across five or more jurisdictions without being re-keyed at each border. The WCO’s framing is the useful point for administrations: a digital corridor is only as interoperable as the standards its members share, which is why the Data Model and SAFE are presented as the foundation rather than any single national system. Traders routing freight through the corridor should watch for advance-information and digital-transit arrangements between Kazakhstan and its neighbours, since those are what will determine actual transit times.
WCO: Operation COLIBRI ZAFIRO targets general aviation crime across nineteen countries
World Customs Organization, 7 September 2026. The WCO reported the results of Operation COLIBRI ZAFIRO, a sixteen-day operation across nineteen countries in Latin America, the Caribbean and West and Central Africa targeting illicit trafficking by general aviation. Customs administrations, police, anti-narcotics units, civil aviation authorities and military forces carried out 1,431 general aviation controls, seized approximately 1.2 tonnes of narcotics in four seizures and eleven light aircraft in Bolivia, and identified eighty-six clandestine airstrips. The operation was coordinated through three Operational Coordination Units, a central unit in Lisbon and regional units in Abidjan and Buenos Aires, with analysts using risk analysis and the WCO Geoportal to identify suspicious flight patterns and support real-time decisions. The release is published by the WCO.
What it means. The figures are less instructive than the operating model. The operation was intelligence-led rather than built on routine inspection, ran through standing multi-agency coordination units across time zones, and used a shared geospatial platform to turn flight data into targeting decisions. That is the same architecture, applied to aircraft, that risk-based customs control applies to containers and parcels, and it is a reminder that the enforcement dimension of a modern administration depends on data sharing and inter-agency coordination as much as on officers at the border. Administrations building or refreshing their risk-management capability, particularly those with exposure to small-craft and light-aircraft smuggling, will find the coordination structure a useful reference.
