Sourcing frozen whole milkfish from China

14% duty on the proposed milkfish line

Read from the UK Trade Tariff on 4 October 2026, heading 0303 covers frozen fish excluding fillets and other fish meat. The proposed milkfish line, 0303 89 90 92, carries 14% duty from China, with no anti-dumping or countervailing duty and no suspension shown. The table presents buying formats under the same tariff line, rather than separate commodity classifications.

The line attaches veterinary, illegal fishing and organic import controls, plus a CITES export control. Ask your customs broker or the relevant authority to confirm establishment approval, health certification, advance notification and the suitable border control post for your consignment. Confirm whether wild-caught fish needs a validated catch certificate and whether fish farmed from fry or larvae qualifies for an exemption. Confirm the organic and CITES requirements with your customs broker where relevant.

Confirm the commodity code using the scientific name, whole-fish presentation and processing details before relying on this rate. A supplier's description of the fish as farmed does not establish its tariff classification. For the wider heading, see the frozen whole carp guide.

Specify the milkfish and its presentation

Put the scientific name on the purchase specification and match it to the supplier's product records. Agree whether the fish is ungutted or gutted, whether the head remains attached, and whether it is individually frozen or block frozen. Specify size grades, acceptable broken tails, declared net fish weight, glaze and carton packing.

Obtain a sample for thawing and cooking. Assess flavour, flesh texture, belly condition and bones against the intended catering use. Ask for farm or catch records and batch-linked residue results. Before shipment, ask port health to confirm the China-specific attestation route; the attestation must include the results of the required tests.

Worked duty example

Illustrative example, not a quote: Illustrative order: two tonnes of frozen whole milkfish; values are hypothetical. under 0303 89 90 92, invoiced at £16,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £17,500. Duty at 14% is £2,450. Import VAT at 20% is charged on the customs value plus duty, £19,950, so it is £3,990. Import taxes total £6,440; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £2,450 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

Identity and documents: match the species, batch marks and establishment number across cartons, packing records and health certification. Review the residue reports against the actual shipment.

Weight and grading: deglaze samples from different cartons, weigh the drained fish and compare size grades with the specification. Solid foods packed in an ice glaze must show drained net weight.

Condition and temperature: inspect skin, bellies and tails for damage, freezer burn and signs of thawing. Measure core temperature on arrival and review the refrigerated transport record.

Packing and labels: check seals, legible batch marks, storage instructions and the declared species, production method and farming or catch area. Compare the delivered pack with the approved sample.

What goes wrong

A whole-milkfish order can arrive with mixed sizes, excessive glaze, split bellies or damaged tails. A gutted specification may be supplied ungutted, while an individually frozen pack may contain fish frozen together. Deglazing, thawing and cooking samples help reveal differences that a carton photograph cannot establish.

Document mismatches and missing residue evidence can disrupt clearance. Verify the establishment and shipment records before loading, and agree how temperature excursions and rejected cartons will be handled. Use a factory verification brief and a product-specific inspection plan.
