How to Clear Goods Through CDS in 8 Steps

A lorry can be booked, a vessel can be due to berth and the commercial paperwork can look complete – but goods will not move as planned if the customs declaration is missing, inaccurate or cannot be matched to the border process. Knowing how to clear goods through CDS means treating customs as an operational workflow, not a last-minute form to submit.

For UK importers, exporters, hauliers and forwarders, the Customs Declaration Service (CDS) is the system used to submit customs declarations to HMRC. Clearance through CDS depends on accurate data, the right customs procedure, a valid payment method and, where relevant, completion of the linked port, inventory, GVMS or safety and security process.

How to clear goods through CDS: the 8-step process

1. Confirm who is making the declaration

Start by deciding whether you will submit the declaration yourself, use a customs agent or operate a hybrid model. The legal responsibility does not disappear simply because a third party submits entries on your behalf. The importer or exporter must understand what is being declared and ensure the information supplied is correct.

If you are declaring in-house, your business needs the relevant EORI number, access to CDS through compatible customs software and a clear process for collecting data from purchasing, warehousing, transport and finance teams. If an agent is acting for you, agree the representation model and provide instructions early enough for checks to be completed before the goods arrive or depart.

This decision often comes down to volume, complexity and internal expertise. A regular importer with consistent commodity lines may benefit from processing declarations in-house. A business handling infrequent, high-risk or varied shipments may prefer agency support while its team builds confidence.

2. Identify the correct customs procedure

The declaration must state what is happening to the goods. For a straightforward UK import, the goods may be entered to free circulation, allowing them to remain in the UK once duty and import VAT obligations are addressed. But this is not always the best or correct route.

Goods moving to a customs warehouse, arriving temporarily, being repaired, re-exported or travelling under transit need a different procedure. Reliefs and special procedures can reduce or suspend duty in the right circumstances, but they bring authorisation requirements, record-keeping duties and deadlines. Selecting a procedure simply because it appears cheaper can create a compliance issue later.

Before the declaration is prepared, establish the goods’ final destination, whether they will be sold, stored, processed or re-exported, and whether any duty relief or preference is being claimed. That operational context drives the declaration data.

3. Build the declaration data from reliable documents

CDS uses structured data rather than the old-style box-by-box approach familiar from CHIEF. The practical point is the same: each data element needs to reflect the actual transaction and movement.

Your commercial invoice, packing list, purchase order, transport document and supplier information should align. Differences in quantities, values, currencies, consignee details or goods descriptions are common reasons for delays and post-clearance queries. Do not rely on a vague invoice line such as “parts” or “samples” when the goods need a defensible customs description.

At minimum, your team should verify the importer and exporter details, EORI numbers, country of dispatch and origin, item quantities, gross and net mass, invoice value, Incoterms, freight and insurance charges, transport details and any licence or certificate requirements. The exact data required varies by movement and procedure, so a repeatable shipment checklist is useful.

4. Classify the goods and establish origin and value

Three elements determine much of the customs treatment: commodity code, origin and customs value. They are connected, but they are not interchangeable.

The commodity code identifies the product for customs purposes and determines the duty rate, import controls and possible additional measures. Classification should be based on what the product is, how it works, what it is made from and, in some cases, its intended use. A supplier’s code can be a useful starting point, but it should not be accepted without review.

Origin is about where goods are deemed to originate under customs rules, not merely where they were shipped from. This matters when claiming preferential tariff treatment under a trade agreement. A statement on origin may support a claim, but only if the goods meet the relevant rules of origin and the supporting evidence is retained.

Customs value is usually based on the transaction value, adjusted where necessary for costs such as transport, insurance, royalties or commissions. A low invoice value is not automatically the customs value. Getting these three areas right is fundamental to accurate duty and VAT calculation.

5. Check licences, controls and supporting evidence

Some goods need more than a customs declaration. Controlled products may require licences, health certificates, permits, inspection arrangements or pre-notification before clearance can be granted. Examples can include animal products, plants, food, chemicals, excise goods, military or dual-use items and certain waste movements.

The key is to identify restrictions before the goods are loaded, not when they are waiting at the port. A declaration can be technically complete and still be held because the required document reference, licence quantity or border control process has not been satisfied.

Keep copies of commercial documents and evidence supporting the declaration. Customs declarations are not finished when goods are released. HMRC may ask for proof of classification, origin, value, preference claims or authorisations after clearance.

6. Submit the declaration through CDS

Once the data has been checked, submit the import or export declaration through CDS using customs software or through your appointed agent. Directly connected software can guide users through the data required, apply validation rules and return customs messages in a format that an operations team can act on.

A successful submission does not always mean the goods are immediately cleared. CDS may return a declaration reference, request further action, route the goods for documentary or physical examination, or calculate charges that must be settled. Monitor messages rather than assuming that an accepted entry equals release.

For imports at inventory-linked locations, the declaration must be properly associated with the arrival record held by the port or terminal community system. For pre-lodged and GVMS movements, the declaration reference must be correctly linked to the goods movement reference. The detail depends on the route and location, which is why transport and customs teams need to work from the same shipment information.

7. Arrange duty and import VAT payment

Goods cannot normally be released to free circulation until customs debt requirements have been met. Businesses may pay duty and import VAT by immediate payment, use a duty deferment account or, where eligible, use postponed VAT accounting for import VAT.

A deferment account can support faster, more predictable clearance, but it must have sufficient available balance and the right guarantee arrangements where applicable. If you are using someone else’s deferment account, make sure that permission and instructions are in place before submission.

Postponed VAT accounting changes how import VAT is accounted for on the VAT Return; it does not remove the need for a correct customs declaration. Finance teams should reconcile monthly postponed import VAT statements against customs entries and purchase records. This is particularly important where values, supplementary costs or corrections are involved.

8. Obtain release and close the transport process

The final operational milestone is customs release. Depending on the route, you may receive a release message, a permission-to-progress outcome, a notification through an inventory system or a status that allows the haulier to continue. Do not instruct collection or onward delivery until the relevant release status is confirmed.

If goods are selected for a check, respond promptly and make documents available. A delay is not always a declaration error; it may be a routine customs or border agency intervention. However, clear internal ownership prevents a routine query becoming a costly demurrage, storage or missed-delivery problem.

After release, retain the declaration reference, customs messages, invoices, origin evidence, licences and transport documents. If you discover an error, assess whether an amendment, invalidation request, voluntary disclosure or repayment claim is required. The appropriate action depends on the error, the timing and whether duty or VAT has been affected.

Common reasons CDS clearance is delayed

Most avoidable delays are caused by poor data handovers rather than a single complicated customs rule. A missing EORI number, an incorrect commodity code, an unsupported preference claim, a customs value that excludes relevant costs or a declaration submitted against the wrong arrival record can all stop goods moving.

Timing also matters. Sending customs instructions after a trailer has reached the port leaves little room to resolve a query, obtain a licence reference or correct a mismatch. Build customs data collection into the booking and despatch process, especially for groupage, mixed consignments and goods moving between Great Britain, Northern Ireland and Ireland.

For businesses new to CDS, training operational staff to recognise the information customs teams need can be as valuable as training declarants themselves. The buyer who agrees Incoterms, the warehouse team that confirms quantities and the transport planner who creates the movement reference all influence whether the declaration can be completed correctly.

Make clearance repeatable, not reactive

The best CDS process is not necessarily the one with the fewest people involved. It is the one where responsibilities are clear, data arrives early and exceptions have an owner. For some businesses, that means using easy-to-use software to process customs declarations in-house. For others, it means combining internal control with specialist agency support for unusual movements or busy periods.

Custran helps businesses choose the level of support that fits their operation, from customs software and training to hands-on declaration processing. When customs is built into daily transport planning rather than treated as a border-side emergency, goods are far more likely to keep moving when it matters.
