Two back-to-back events in April 2026, a conference in Brussels on the new Union Customs Code hosted by ICC Be, and the latest meeting of the ICC Customs and Trade Facilitation Commission hosted by ICC NL, offered a useful snapshot of where global customs is heading. Different audiences, different levels of detail, but the same underlying currents. Four trends in particular deserve business attention this year.

In one minute (for non-specialists)

If your business ships goods across borders, or works with companies that do, the systems governing those movements are being rewritten.

The EU is building a single digital platform to replace 27 national customs systems, starting with e-commerce in 2028 and extending to all trade by 2034. Worldwide, customs authorities are shifting from checking paperwork to analysing live data, with artificial intelligence doing more of the work every year. Companies that share clean, consistent data with customs get faster clearance; those that don't get more friction at the border.

Four trends stand out in 2026: data quality becomes a business priority, AI is changing how controls work, "trusted trader" status is being redefined, and global rules are harmonizing, but unevenly. The rest of this article explains each, with a short glossary of the main terms at the end.

1. Data is becoming the unit of customs compliance

For decades, customs has been organised around declarations. A trader submits an entry summary, an import declaration, a transit message, an export declaration, often into separate national systems, often with overlapping content. The EU's new Union Customs Code, politically agreed in late March, is the clearest signal yet that this model is giving way to something else: a data-driven, consignment-centric system in which the same information is submitted once and consumed many times. The EU Customs Data Hub will go live for e-commerce in July 2028 and become mandatory for all operators by 2034.

The same shift is visible at global level. The World Customs Organization's 2025 edition of the SAFE Framework of Standards makes data harmonisation one of its headline priorities, explicitly to reduce duplication and streamline cross-border processes. At the operational level, Dutch Customs is piloting what it calls "digital corridors", arrangements with trusted operators who make supply-chain data available via API, in exchange for lighter-touch controls at the border. The conceptual direction of travel is unmistakable.

For business, the practical implication is that data quality moves from being a back-office concern to a compliance KPI. Unique identifiers that follow a consignment from origin to destination, consistent product classifications, clean master data on parties in the chain — these stop being "nice to have" and become the basis on which risk, duty and release decisions are made. Several speakers at both events made the same point in different words: the technology is not the problem, the data model is.

2. The AI adoption gap is widening, not narrowing

The WCO's 2026 Study Report on Disruptive Technologies, based on a survey of 116 customs administrations, makes for sobering reading. Only around 10 percent of administrations report using artificial intelligence or machine learning in production. Another 37 percent are experimenting or piloting. Roughly 30 percent still describe themselves as "operational", meaning foundational systems are in place but limited advanced analytics. Against this, private-sector adoption of AI has accelerated sharply. UNCTAD projects the technology will be the frontier technology with the largest market size by 2033, at around USD 4.8 trillion.

The gap has two consequences. First, administrations will increasingly rely on private-sector data quality and self-assessment because they cannot inspect their way through growing volumes, 5.8 billion e-commerce items entered the EU alone in 2025. Second, where administrations do deploy AI, they deploy it in ways that demand more from industry, not less. Several customs authorities are now using large data models to identify "risk clusters" at a macro level, then asking individual importers to prove their specific shipments are outside those clusters. Rotterdam's AI-driven x-ray image recognition is an encouraging example of how automation can raise coverage without adding headcount. But the gap between administrations with that capability and those still working from paper-based processes is not closing.

3. The trust architecture is being rebuilt

A common thread across the EU reform, the WCO SAFE update, and recent bilateral trade agreements is that the relationship between administrations and compliant businesses is being redefined. Three examples make the pattern visible.

In the EU, the new Trust & Check trader regime, on top of the existing AEO programme, offers self-assessment, self-release and reduced controls to companies willing to grant customs real-time access to their data. This is a significant step beyond AEO: the balance of effort shifts from periodic audit to continuous visibility. Whether the benefits will justify the investment for most companies is an open question, and one industry is actively shaping through the delegated acts still being drafted. At the same time, the EU's co-legislators wisely chose to retain AEO in parallel, preserving a more accessible tier for companies that cannot or will not go that far.

In origin certification, research presented at recent WCO events suggests full self-certification does not produce measurably lower compliance than third-party certification. That evidence is nudging administrations that had resisted the shift. But the picture is not uniform: India's new "authentication" requirement under the EU-India and UK-India agreements introduces a verification layer on top of self-certification, requiring exporters to provide additional identifiers through new IT systems. The UK and the EU have built two different solutions. Expect this pattern, self-certification at the level of principle, authentication in the detail, to spread.

On the platform side, e-commerce marketplaces are being drawn into the compliance chain as "deemed importers", liable for customs compliance, duty and VAT on goods sold to EU consumers. The shift in responsibility is less a change of doctrine than a recognition that trust, data and liability must be realigned for the actors who actually hold the commercial information.

4. Harmonisation is uneven and will stay that way

Against the direction of travel towards greater integration, real-world harmonisation remains patchy. HS 2028 was finalised in January 2026 and enters into force across the WCO membership in 2028, but a meaningful number of countries are still implementing HS 2017, with all the friction in correlation tables, tariff engineering and origin determinations that implies. In the EU reform, centralised customs clearance for imports is being introduced, but the VAT framework has not been aligned, leaving a gap industry has flagged as a missed opportunity. Penalties are only partially harmonised: the final text sets a minimum common core of infringements and non-criminal sanctions, but Member States retain room to add national sanctions on top. The United States is debating a bill that would replace its first-sale valuation rule with a last-sale rule, converging with other jurisdictions but doing so through a politically charged process with affordability implications for consumers.

None of this is an argument against the direction of travel. But it is an argument for realism about timelines and transition costs. Companies operating across multiple jurisdictions will continue to need parallel capability for some years, systems, data, and compliance processes that accommodate different rules, different timings, and different assumptions.

So what?

The operational substance of customs reform is being written now, in the delegated and implementing acts of the EU Union Customs Code, in the explanatory notes accompanying HS 2028, in the work programmes of the WCO Permanent Technical Committee and its technical sub-committees, and in the bilateral IT systems being built around new trade agreements. These are not abstract debates. They will determine the data companies have to provide, the systems they have to connect to, the trusted-trader status they can realistically target, and the penalties they are exposed to.

The practical channels for businesses to engage are well established: national trade facilitation committees, industry federations, chambers of commerce, and global business organisations with formal observer status at the WCO. Where those channels are used well, the detail reflects operational reality. Where they are not, business ends up implementing rules that were designed without it. The next twelve months, between now and the first EU Data Hub go-live in mid-2028, will set the tone.

Key terms at a glance

Harmonised System (HS) — the global product-classification language used by customs authorities in 200+ countries. Every tradeable good is assigned an HS code, which drives duty rates, origin rules and statistics. The system is updated every 5–6 years by the WCO.

HS 2017 / HS 2022 / HS 2028 — successive editions of the Harmonised System. HS 2028 was finalised in January 2026 and takes effect in 2028; many countries are still implementing HS 2017 or HS 2022, which creates classification gaps between trading partners.

WCO (World Customs Organization) — the Brussels-based body that develops global customs standards, including the Harmonised System and the SAFE Framework. 185+ member administrations.

Union Customs Code (UCC) — the EU's foundational customs law. The "new UCC" is the reform politically agreed in March 2026, introducing the EU Customs Data Hub, the EU Customs Authority and the Trust & Check trader regime.

EU Customs Data Hub — a single EU-wide digital platform that will replace the 111 national and EU customs IT systems currently in use. E-commerce goes first in 2028; all trade by 2034.

AEO (Authorised Economic Operator) — the existing trusted-trader status in the EU and most major economies. Companies meeting security and compliance criteria get lighter-touch treatment at the border.

Trust & Check — a new, higher-tier trusted-trader regime in the EU reform. In exchange for giving customs real-time access to company data, traders get self-assessment and self-release. AEO remains in parallel.

Deemed importer — an e-commerce platform or marketplace treated, for customs and VAT purposes, as if it were the importer of the goods it sells — even if it never physically handles them.
