UK Commodity Code
🔒 Checklist: Identify 2027 commodity code changes, review classifications and update customs records before affected shipments are delayed.
About the AssetThe 2027 commodity code changes create a timely reason for UK importers and exporters to examine the accuracy of their product classifications and customs records. The UK Commodity Code Checklist provides a structured review process covering exposure identification, classification checks, product data amendments, broker communication, shipment readiness and internal controls. It includes a product classification change register and management readiness assessment to help businesses assign responsibility, track amendments and identify outstanding work before the new tariff year. The objective is practical: identify potentially affected products, correct relevant records and reduce the risk of customs processing delays caused by outdated or inaccurate commodity codes. |
1. Executive Overview
The UK Trade Tariff has published its 2026–2027 eight-digit commodity code correlation table, dated 9 November 2026. The table highlights 43 commodity code changes that businesses should examine ahead of the New Year.
For importers and exporters, this is more than an annual tariff update. A commodity code used in an existing product record may need to be reviewed, amended or replaced. If an outdated or incorrect code remains in a business's systems, it can create problems when preparing customs declarations and processing shipments.
The key task is to identify affected products before the changes take effect, establish the correct classification for each product and ensure that the updated information reaches everyone involved in the customs process.
This checklist provides a structured review process to help businesses identify exposure, manage amendments and prepare their customs data for 2027.

2. Establish Your Exposure to the 2027 Changes
Before making amendments, establish which products and business activities may be affected.
Initial exposure assessment
Obtain the official 2026–2027 eight-digit commodity code correlation table.
Confirm that the table being used is the version published on 9 November 2026.
Identify all commodity codes currently used by your business.
Export your existing product classification records from your customs or enterprise resource planning system.
Identify products regularly imported into the UK.
Identify products regularly exported from the UK.
Identify dormant product records that may still be used for future shipments.
Identify products managed by customs agents, brokers or external logistics providers.
Compare your existing codes against the changes identified in the official correlation table.
Flag every potentially affected code for further review.
Management checkpoint: Do not assume that a code is unaffected simply because it has not been used recently. Check dormant records where the product may return to active trade.
3. Review the Accuracy of Existing Commodity Codes
A change to a code does not automatically mean that the underlying product has changed. The classification must still reflect the product's objective characteristics and the applicable tariff requirements.
Classification review
Confirm the product's current description.
Check the manufacturer's technical specifications.
Review the product's composition, material and principal function.
Confirm whether the product has multiple components or functions that may affect its classification.
Compare the existing code with the relevant 2027 tariff information.
Identify codes that have been replaced, divided, combined or otherwise changed, where indicated by the official correlation information.
Check whether the proposed replacement code accurately describes the product.
Review the relevant tariff heading, subheading and applicable classification notes.
Record the reasoning supporting the selected tariff classification.
Escalate uncertain or disputed classifications for specialist review.
Important: A correlation table helps identify relationships between codes across tariff years. It should not be treated as an automatic classification decision for every product. Businesses must establish the correct code for the goods concerned.
4. Identify Products Requiring Code Amendments
Create a controlled record of every product potentially affected by the changes.
Product-level review
Identify the existing code assigned to each affected product.
Record the proposed 2027 code, where established.
Confirm whether the product description requires amendment.
Check whether several products currently share the same code.
Identify products that may require separate classification assessments.
Check whether the change affects only the code or also requires a review of the product's classification.
Record the date on which the new classification was verified.
Assign responsibility for approving each amendment.
Retain supporting classification evidence.
Product classification change register
Product reference | Product description | Existing code | Proposed 2027 code | Review status | Responsible person |
Pending / Reviewed / Approved | |||||
Pending / Reviewed / Approved | |||||
Pending / Reviewed / Approved |
Use this register to track progress and prevent unreviewed codes from being carried into the new year.
5. Update Your Customs Master Data
Identifying a code change is only the first step. The revised information must be reflected consistently across the systems and records used by the business.
Data and systems review
Update approved commodity codes in your customs master data.
Update the relevant product records in your ERP system.
Check product databases used by purchasing and sales teams.
Update customs software and declaration platforms.
Check whether spreadsheets or manually maintained product lists contain outdated codes.
Remove or deactivate obsolete codes where appropriate.
Retain an audit trail showing the old and revised codes.
Confirm that the revised information is available to authorised employees.
Check that product descriptions remain consistent across systems.
Confirm that duplicate or conflicting product records have been addressed.
Management checkpoint: A code corrected in one system but left unchanged in another can still cause errors. The review should cover every system that supplies product information to customs declarations.
6. Notify Customs Brokers and Logistics Partners
External service providers may rely on product data supplied by your business. If they continue using old information, the classification review may not prevent declaration problems.
External communication checks
Identify all customs brokers and agents handling your UK imports and exports.
Identify logistics providers that prepare or transmit customs information.
Send approved commodity code amendments to the relevant providers.
Include the product reference and revised code in the communication.
Confirm when the amended information will be applied.
Ask providers to identify any open instructions or templates containing old codes.
Update standing customs instructions where necessary.
Retain written confirmation of important amendments.
Establish a contact for resolving classification queries.
Management checkpoint: Do not assume that updating your internal system automatically updates a broker's records. Obtain confirmation that the relevant external records have also been amended.
7. Review Shipments Around the Changeover
The transition between tariff years requires particular attention to shipments being prepared, declared or dispatched around the changeover.
Shipment readiness checks
Identify shipments planned around the end of 2026 and beginning of 2027.
Identify products in transit that may arrive or be declared after the changeover.
Check which commodity code is appropriate for each relevant customs declaration.
Confirm that the declaration data supplied to the broker is current.
Check open purchase orders and sales orders containing affected products.
Review draft declarations that may contain outdated codes.
Confirm that the person responsible for shipment release has access to the approved product information.
Escalate unresolved classification issues before affected shipments are processed.
Management checkpoint: Do not rely on the date a purchase order was raised or a shipment was booked to determine which tariff information applies. Confirm the applicable requirements for the relevant declaration and transaction.
8. Introduce Internal Controls for Future Commodity Code Changes
The 2027 update should also be an opportunity to improve how your business manages future tariff changes.
Ongoing control checks
Assign a responsible owner for monitoring UK Trade Tariff updates.
Establish a regular review of commodity code changes.
Maintain a central register of approved product classifications.
Record the source and reasoning supporting each classification.
Establish an approval process for new or amended codes.
Ensure purchasing, sales, logistics and customs teams know where to obtain approved codes.
Introduce a process for notifying brokers when codes change.
Retain historical classification records for audit and reference purposes.
Schedule periodic reviews of high-volume and frequently traded products.
Include commodity code accuracy in internal customs compliance checks.
