The OCS Export Academy – Essential Q4 2026 Customs Changes You Need to Know

Global Trade Update: The final quarter of 2026 is bringing significant regulatory changes to international shipping.

From mandatory EU data requirements to updated HMRC procedures, customs authorities worldwide are tightening controls.

At OCS Worldwide, our Export Academy continuously monitors these shifts. We are managing these updates behind the scenes to keep your shipments moving seamlessly, but here is what you need to know about the changing landscape this month.

The 1 November EU Product Identifier Mandate

Effective 1 November, 2026, the European Union requires mandatory Product Identifiers (PIDs) for distance-sale imports. Incomplete or non-compliant data will result in rejected declarations and delayed parcels.

Our IT and Compliance teams are currently rolling out system updates to support these new data elements. To ensure seamless clearance into the EU, your shipment data will need to include the following codes where applicable:

• C127 – Merchant Product Identifier: Mandatory for all applicable shipments
• C128 – Non-standardised Manufacturer PID: Mandatory
• C129 – Standardised Manufacturer PID: Required where one exists
• Y081 – No standardised identifier exists: Used in place of C129 where applicable

Note: The EU is also introducing a statutory customs handling fee on 1 November. We are actively working with our European brokerage partners to confirm the final fee structure. Once established, we will provide a transparent update on how this will be applied.

UK & Northern Ireland: EORI and CDS Adjustments

HMRC has introduced operationally relevant changes to its Customs Declaration Service (CDS) guidance, specifically impacting exports from Northern Ireland.

• EORI Usage. A recognised EU or XI EORI is now normally required for the exporter. A GB EORI is only permitted in highly specific, limited circumstances (such as re-exporting goods entered to a special procedure prior to the EORI changes).
• Establishment Rules. Exporters must be established in Northern Ireland or the EU. If the exporter is not established in these regions, an indirect representative must generally be used.
• System Integrity. We have updated our DUCR (Declaration Unique Consignment Reference) generation rules to accommodate the specific character-length requirements of EU EORIs. This ensures your declarations are accepted on the first attempt.

North American Customs Deadlines

United States: On 22 October, 2026, US Customs and Border Protection (CBP) will begin enforcing additional exclusions from the postal informal-entry procedure. OCS mitigates this risk by ensuring our commercial ecommerce traffic utilises secure, direct entry types rather than relying on the international postal procedure, shielding your shipments from these new bottlenecks.

Canada: We are closely monitoring the application of the CPUKT tariff treatment for eligible UK-origin goods, as well as managing the strict application of Canadian surtaxes (15%, 25%, or 50%) on listed US-origin goods. Accurate origin data — not just the country of dispatch — is critical to avoiding unexpected duties.

Enhanced Scrutiny on Air Cargo Safety

Aviation authorities and the IATA continue to tighten controls around undeclared dangerous goods. Standard airport screening is no longer the sole line of defence. Exporters must ensure rigorous product categorisation, particularly for everyday items that are classified as restricted, including:

• Aerosols and room air fresheners
• Lithium batteries
• Perfumes
• Electronic cigarettes

We operate a multi-layered compliance program — including rigorous warehouse-recognition training and strict product assessments — to ensure your cargo complies with all aviation safety standards and avoids quarantine.
