Sourcing dried kombu kelp from China

Duty on dried edible kombu

Read from the UK Trade Tariff on 4 November 2026, dried kombu fit for human consumption under 1212 21 00 00 carried 0% duty from China. The supplied record shows no anti-dumping or countervailing measure and no suspension. Heading 1212 covers seaweeds and other algae, including dried or ground goods, alongside other vegetable products.

The tariff attaches an organic import control. For organic kombu from China entering Great Britain, obtain a certificate of inspection for each consignment and check the exporter’s control body and export country against the non-UK organic registers. The importing business must be UK-based and certified by an approved UK control body.

The table shows buying forms within the same edible seaweed line, rather than separate tariff subdivisions. Confirm the species, ingredients, processing and intended use with your broker using finding your commodity code. For other products in the heading, see seaweed and algae.

Specify kombu species, cut and drying

Specify the botanical species rather than accepting ‘kombu’ alone. Record harvest origin, whole blades or cut form, thickness, colour, broken pieces, moisture acceptance and whether the product is washed or has added ingredients. Approve a reference sample and agree a repeatable soaking and stock-making comparison.

Agree testing for iodine, inorganic arsenic, other heavy metals and microbiological quality with a food laboratory, using the intended preparation and consumption to set the brief. These are buyer checks, not a universal mandatory test panel. Importers must ensure food is safe and legal before it enters Great Britain.

Worked duty example

Illustrative example, not a quote: Illustrative order: 500 kg of dried edible kombu kelp under 1212 21 00 00, invoiced at £2,500 free on board, with £900 of freight and insurance to the UK. The customs value is £3,400. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,400, so it is £680. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. 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 cut: compare sampled blades or pieces with the approved species documentation and reference sample; check thickness, breakage, sand and foreign material.

Drying and packing: check measured moisture against the contract, inspect for mould or musty odours, and check moisture-resistant liners, seals and carton condition on arrival.

Cooking performance: use the agreed soaking and stock-making method to compare flavour, texture, sediment and consistency between lots.

Labels and records: check that packaged food identifies the marketing business or importer by name and address. Match batch markings to packing records and laboratory reports, and check organic paperwork where applicable. See quality inspection explained.

What goes wrong

A common name can conceal a species substitution, and a good-looking sample can conceal inconsistent blade thickness or excessive broken pieces in production. Damp packing, damaged liners and condensation can leave stock musty or mouldy. Retain samples and photograph defects before agreeing a remedy.

An organic logo on a supplier’s bag is not a substitute for the import certificate and control-body checks. Settle the documentary route before shipment. A generic seaweed test report also gives little buying assurance unless its sample identity and batch match the kombu being supplied.
