Do Northern Ireland imports need a tariff ruling?
For a binding classification decision on Northern Ireland imports, use Binding Tariff Information rather than a GB Advance Tariff Ruling. A ruling is optional, and you must apply before customs procedures are completed. Prepare evidence of the actual product with Cambridge China Bridge.

Choose the route before preparing an application
A binding classification decision is optional. For Northern Ireland imports, the relevant decision is Binding Tariff Information; Great Britain uses an Advance Tariff Ruling. Read our commodity code guide for classification basics and our Advance Tariff Ruling guide for the GB route.
HMRC says the application route depends on where you are established and where the goods move. Before preparing a file, ask its Tariff Classification Service to confirm the route for your business, particularly if you are based outside Northern Ireland.
Register, then apply through the portal
HMRC’s registration instructions ask for your name, contact email, an XI-prefixed EORI number valid within the EU, and your status as trader or agent. Contact the Tariff Classification Service for portal access. Follow the official page’s email and subject-line instructions, then keep the access link.
Apply through the EU Customs Trader Portal using the link HMRC supplies. Assign a representative through that portal if someone applies for you. Each type of goods needing a decision requires a separate application, so organise the factory’s range by product type before submission.
Build evidence around the actual product
HMRC asks for detailed product information and, where appropriate, brochures, manuals, photographs and samples. Tell HMRC if this material should remain confidential. A sales name alone gives the reviewer little to work with.
Ask the factory for materials, composition, function, operating method, drawings and photographs of the complete item. Match the documents to the model you intend to buy and explain differences between variants. Cambridge China Bridge’s staff in China can help collect this evidence. Use our quality inspection guide when checking production against the described product.
Allow time before customs clearance
Apply before customs procedures are completed: decisions cannot be retrospective. HMRC aims to provide portal access within 5 working days and reply to the application within 120 days. These are stated aims, so avoid making shipment commitments that depend on receiving an earlier decision.
Prepare the evidence while the specification is being agreed. Keep a record of what was submitted, answer requests promptly, and tell your customs agent if shipment plans change while the application is pending.
Frequently asked questions
Is Binding Tariff Information compulsory?
No. A legally binding classification decision is optional. Consider it when classification uncertainty makes it difficult to commit to an order or plan clearance.
Can I use the GB Advance Tariff Ruling route?
For a binding decision on Northern Ireland imports, use Binding Tariff Information. The Advance Tariff Ruling route is for Great Britain.
Do I need to send HMRC a sample?
HMRC asks for samples where appropriate, alongside detailed information and supporting documents. Ask what is needed for your product before arranging dispatch.
Can I apply after the goods have cleared customs?
The decision cannot be retrospective. Apply before customs procedures are completed; start gathering product evidence before shipment.
