Sourcing frozen whole mackerel from China

Mackerel duty and species differences

Read from the UK Trade Tariff on 4 October 2026, frozen chub mackerel under 0303 54 10 96 carried 20% duty for goods from China. Heading 0303 covers frozen fish, excluding fillets and other fish meat. The supplied facts contain only this named true-mackerel line. The other table rows are comparison products at 14%, not alternative codes for chub mackerel. These selected lines show no anti-dumping or countervailing duty and no suspension.

The selected lines carry veterinary, illegal fishing and organic import controls. For frozen whole mackerel, confirm Chinese establishment approval, health certification, advance notification through the animal-product import system and entry through a suitable border control post with your customs broker. For wild-caught fish, confirm validated catch-certificate requirements with the relevant authority. For organic claims, the inspection certificate is issued by the exporter's control body; confirm the import requirements with your customs broker. The generic comparison line also carries CITES controls; confirm their applicability with your broker.

Confirm the scientific species and presentation before choosing the commodity code. Do not use the horse-mackerel rate for chub mackerel. For prepared products, see canned mackerel sourcing. Confirm the VAT treatment of fish for human consumption with HMRC or your customs broker; see UK import duty and VAT.

Specify the whole fish, glaze and handling

Write the scientific species into the purchase specification, alongside the commercial name. State whether the fish must be ungutted with head and tail intact, the individual weight grade, acceptable broken fish, freezing method, glaze allowance and net fish weight after deglazing. Agree carton construction and whether fish must separate individually after opening.

Ask for catch-area and vessel records, handling and freezing records, and batch-linked histamine test results. Agree the sampling plan with your food laboratory before production. Match the Chinese establishment's approval number to the actual freezing or packing site, rather than relying on the trader's company details.

For retail packs, check English labelling for the species name, production method, catch area, fish allergen, storage instructions and UK business address. Keep the label artwork tied to the agreed species and batch documentation.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2 tonnes of frozen whole chub mackerel under 0303 54 10 96, invoiced at £4,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £5,500. Duty at 20% is £1,100. Import VAT at 20% is charged on the customs value plus duty, £6,600, so it is £1,320. Import taxes total £2,420; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,100 of duty. The import duty and VAT guide explains each step. This assumes the goods are standard-rated for VAT. Most food for human consumption is zero-rated, and animal feed can be too, in which case no import VAT is due, so check the rate for your product in HMRC's VAT Notice 701/14.

Inspection checklist

Species and form: compare sampled fish with the agreed species, weight grade and whole-fish presentation; record substituted species, missing heads, split bellies and broken tails.

Glaze and net weight: deglaze samples from different cartons, weigh the fish and compare the results with the declared net weight and agreed glaze allowance.

Cold chain and condition: measure core temperature on arrival, review the transport temperature record and inspect for freezer burn, yellowing, damaged packs and signs of thawing.

Batch evidence: match cartons, health and catch certificates, establishment approval and histamine reports to the consignment. Plan these checks using the quality inspection guide.

What goes wrong

A quotation saying only 'mackerel' can conceal a species change and a different tariff line. Heavy glaze reduces the fish actually delivered, mixed weight grades disrupt portion planning, and rough handling leaves broken tails or split bellies. Set acceptance criteria in the purchase specification and inspect the production batch before loading.

Cold-chain records and histamine results need separate review. A frozen appearance does not establish the batch's handling history. Missing catch documents, mismatched establishment numbers or certificates describing a different load can also cause border rejection. Check the documents before dispatch and keep any arrival discrepancy tied to its batch.
