Making an import declaration in your records
Source: gov.uk (2025-04-30)

How to declare imported goods to customs, by entering them in your own records.

You should check if you need to declare goods you bring into or take out of the UK (https://www.gov.uk/check-customs-declaration) before you declare them by entering them in your own records.

You can declare your goods by entering them in your own records and sending other details to customs if you:
- have applied to use simplified declarations for imports (https://www.gov.uk/guidance/using-simplified-declarations-for-imports)
- are authorised to use entry in the declarant’s records
There’s different guidance if you are making an import declaration in your records without authorisation (https://www.gov.uk/guidance/making-an-import-declaration-in-your-records-without-authorisation).

How to make an entry in your records

You can declare your goods by entering them in your own records using the entry in the declarant’s procedure, unless they are:
- controlled goods imported at the frontier (for goods imported into Great Britain (England, Scotland and Wales) from Ireland, there is a different list of controlled goods (https://www.gov.uk/guidance/list-of-goods-imported-into-great-britain-from-the-eu-that-are-controlled))
- hydrocarbon oils
- imported under Admission Temporaire or Temporary Admission (ATA) Carnet procedures
- imported under authorisation by declaration
- personal effects
- imported under transfer of residence relief
- agricultural policy goods
- excise goods
- unmanufactured tobacco, not stemmed or stripped
- unmanufactured tobacco, partly or wholly stemmed or stripped
- tobacco refuse
- high, medium and low risk animal products under the Border Target Operating Model (https://www.gov.uk/government/publications/the-border-target-operating-model-august-2023) from EU and European Free Trade Association (EFTA) countries
- high, medium and low risk plant and plant products under the Border Operating Model from EU countries, Switzerland and Liechtenstein
- high risk food and feed of non-animal origin from EU and EFTA countries
What to include

When you enter details of your goods into your records, you’ll need to include:
- the commodity code (https://www.gov.uk/guidance/finding-commodity-codes-for-imports-or-exports)
- the customs procedure code
- your declaration unique consignment reference — which is the main reference number that links declarations
- purchase and, if available, the sales invoice numbers
- the date and time of entry in records — creating the tax point, which is used for working out VAT payments later
- any free zone, customs warehousing, or temporary storage stock account references
- the free zone, customs warehouse, or temporary storage authorisation number
You’ll also need to include:
- a written description of the goods — so they’re easy to identify
- customs value
- quantity of goods — for example, number of packages and items, net mass
- details of licensing requirements and licence numbers
- details of any supporting documents, including the serial numbers, where appropriate, needed before the goods can be released
- details of the person you’re representing if you’re making an import declaration on behalf of someone else
The next step depends on which type of location your goods are imported to:
- inventory-linked locations — locations linked to customs by computer
- locations that are not inventory-linked — locations not linked to customs by computer
Inventory-linked locations

When you enter your goods in your records, you’ll also need to make a customs clearance request (form C21) (https://www.gov.uk/government/publications/import-and-export-customs-clearance-request-c21). This will allow the goods to be cleared from the inventory-linked location where they entered.

The information you provide in the form is similar to the entry you make in your own records. Check ‘completion of import declarations’ in imports and community transport inwards (https://www.gov.uk/government/publications/uk-trade-tariff-imports-and-community-transport-inwards/uk-trade-tariff-imports-and-community-transport-inwards#standard-import-procedures-including-customs-warehouse-removals---general-requirements).

After you’ve made an import declaration in your records

You’ll need to complete a supplementary declaration (https://www.gov.uk/guidance/making-an-import-supplementary-declaration).

You must submit your supplementary declaration no later than the 10th calendar day of the month after the month in which you declared your goods by entering them in your own records.

For example, if you declared your goods by entering them in your own records in January, you must submit your supplementary declaration by 10 February.

If you’ve completed form C21, you must use the date that customs accept your declaration and not the date your goods were entered in your records.

If you’re moving goods from Great Britain to Northern Ireland

Where a standard supplementary declaration is completed for movements, you must provide a final supplement by the 10th calendar day of month after the reporting period when your supplementary declarations were due.

You do not need to provide a final supplementary declaration for movements into Northern Ireland when you have completed the supplementary declaration with the Internal Market Movement Information.

If you are authorised for Authorised Economic Operator (https://www.gov.uk/guidance/apply-for-authorised-economic-operator-status) you may qualify for a Notification of Presentation Waiver. Waivers can only be used when you’re moving standard goods which are ‘not at risk’ using direct transport from Great Britain and Northern Ireland.

Check if you qualify for a Notification of Presentation waiver (https://www.gov.uk/guidance/apply-for-a-notification-of-presentation-waiver-for-goods-moving-from-great-britain-into-northern-ireland).
