Duty and recipe classification

Read from the UK Trade Tariff on 4 November 2026, heading 2004 covers frozen vegetables prepared or preserved otherwise than by vinegar or acetic acid. The other-vegetable and mixture lines shown carry 16% duty from China, with no listed anti-dumping or countervailing duty and no suspension. The carrot and asparagus rows are component comparisons, not alternative codes for seaweed salad.

The tariff attaches veterinary control and organic import control to these lines. For veterinary control, ask your customs broker to confirm the requirement for the complete recipe, including fish seasoning or other animal ingredients, before ordering. Organic imports from China into Great Britain need a certificate of inspection for each consignment, and the exporter's control body and export country must be checked against the non-UK organic registers.

Do not classify by the sales name alone. Give your broker the seaweed species, ingredient proportions, preservation method and processing details to confirm the commodity code. For the wider product family, see seaweed and algae.

Specify the seaweed and dressing

Specify the seaweed species, stem or leaf content, strip size, texture after thawing, colour, dressing quantity, sweetness, acidity and sesame distribution. List every dressing ingredient, including soy sauce sub-ingredients, colours and any fish extract. Agree whether the salad is ready to eat after thawing, its thawing instructions and the storage instructions after opening.

Agree pack format, net weight, seal design and frozen transport conditions. Request batch microbiological results and discuss iodine and heavy-metal testing with a food laboratory. Importers must ensure goods are safe and legal before import into Great Britain; these suggested tests are purchasing checks, not a claim that each test is compulsory.

Worked duty example

Illustrative example, not a quote: Illustrative consolidated catering order: 20 tonnes of frozen seasoned seaweed salad, assuming this code is confirmed; FOB and freight values are illustrative. under 2004 90 98 80, invoiced at £36,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £40,000. Duty at 16% is £6,400. Import VAT at 20% is charged on the customs value plus duty, £46,400, so it is £9,280. Import taxes total £15,680; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £6,400 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

Thawed sample: compare chew, strip integrity, dressing separation and liquid loss with the approved sample.

Recipe and labels: reconcile the ingredient sheet with the artwork. Regulated allergens in prepacked food must be clearly labelled within the ingredients list; check the dressing as well as the seaweed.

Cold chain: review loading and transit temperature records, check product temperature on arrival and investigate heavy ice accumulation or signs of thawing.

Packing: check seals, leaks, net weight and batch identification. Retain samples and photographs using the quality inspection guide.

What goes wrong

A frozen sample can conceal weak texture: thaw it before approval. Excess dressing dilutes the seaweed content, damaged strips become soft, and dressing can separate after thawing. Agree acceptance criteria for thawed appearance and taste rather than approving colour through an unopened bag.

A recipe change can introduce undeclared allergens or animal ingredients without an obvious change in appearance. Reconcile production records, labels and the customs description before dispatch, and isolate arrival stock with unexplained temperature excursions or leaking packs.
