The customs system assigns every declaration to one of the inspection channels based on risk analysis: a documentary check (yellow channel) means verifying the invoice, proof of origin and tariff classification without opening the shipment, while a physical check (red channel) requires physically examining the goods, and sometimes weighing them or taking samples. The channel is generated automatically by the declaration system and depends on factors including the type of goods, the declarant's history, and the country of origin. A physical check always extends clearance time, so it's worth preparing complete documentation to accompany the shipment in advance.

How the declaration and checks work
Getting through the customs declaration stage smoothly requires syncing data between logistics, accounting and the customs representative, so the MRN and the shipment's status are available in real time.

How to stay compliant and keep clean records
Staying compliant once clearance is complete requires systematic record-keeping, readiness to correct a declaration, and a regular review of internal procedures in light of customs rule updates.
Record-keeping, corrections and evidence of due diligence
Customs documentation should be kept for at least 4 years from the date the goods were released (a UK/HMRC requirement), and any correction to a declaration after release requires a written justification and confirmation of acceptance by the authority. Evidence of due diligence - correspondence with the customs agent, a history of tariff queries, and approved Binding Tariff Information rulings - is a key line of defence during a post-clearance audit.
Working with a customs agency and internal audit
The scope of a customs agency's responsibility should be set out precisely in the contract, specifying which data is supplied by the importer and which the agent completes based on its own tariff knowledge. A regular internal audit - at least once a quarter - helps spot discrepancies between system data and paper documentation before they become the subject of an official inspection.
Summary
In summary: when it comes to 'documentary vs physical checks', what matters most is running the process according to current official guidance, with a clear division of responsibility and every decision documented. This approach limits delays, reduces the number of corrections and makes it easier to defend your records during an inspection. If any requirement is unclear, check the current guidance from the customs authority or consult an authorised customs representative.

Frequently asked questions
What's the difference between a documentary check and a physical check of goods?
A documentary check verifies the accuracy and completeness of the customs documents - the invoice, the packing list and the declaration - without physical access to the load. A physical check means inspecting the goods themselves: their quantity, markings, packaging, and whether they match the declared description. The customs authority can order both forms at once, or independently, depending on the shipment's risk profile and the result of the system's analysis.
What documents are mandatory for importing into the United Kingdom after Brexit?
The minimum set includes: a commercial invoice showing the customs value, a specification of the goods (packing list), a transport document (CMR, AWB or B/L), the importer's EORI number, and the goods' tariff code under the UK Global Tariff. For regulated goods, phytosanitary certificates, import permits or UKCA declarations of conformity are also required.
What are the consequences for a company of mistakes or gaps in customs documentation?
Formal mistakes can result in the goods being held and storage costs being charged. Understating the customs value or an incorrect tariff classification leads to unpaid duty, VAT, interest and an administrative penalty. HMRC can open an inspection going back up to 4 years, and up to 20 years in cases of deliberate fraud.
How long does customs documentation need to be kept after clearance is complete?
Under HMRC's requirements, customs documentation should be kept for a minimum of 4 years from the date the goods were released in the United Kingdom. For special procedures - such as a customs warehouse, temporary admission, or simplified AEO procedures - the record-keeping requirement can be longer, in line with the terms of the individual authority decision. In the EU, the period is generally 3-5 years, depending on the member state.
When is it worth using a professional agency for customs handling instead of doing it yourself?
A customs agency is especially valuable for special procedures (T1, Regime 42, ATA Carnet, customs warehousing), for goods subject to sanitary or phytosanitary checks, and when a company doesn't have trained staff or an active EORI number. The agency is jointly liable for the accuracy of the declarations submitted, which provides an important legal safeguard for the importer or exporter.
