Sourcing dried agar seaweed from China

Dried agar seaweed: 0% duty

Read from the UK Trade Tariff on 30 September 2026, heading 1212 covers seaweeds and other algae, including dried material, whether or not ground. For dried agar seaweed, 1212 21 00 00 covers material fit for human consumption; 1212 29 00 90 covers other dried material. Both carry 0% duty from China, with no anti-dumping or countervailing duties and no suspensions recorded in the supplied tariff facts. The table separates product forms sharing these codes.

Both lines carry organic import control. Your company must be based and certified in the UK to import organic products. The exporter’s control body issues the certificate of inspection, and organic imports must use the recognised countries, territories and control bodies. For a Chinese consignment, ask your customs broker and organic control body to confirm the certificate and clearance requirements before shipment.

This guide concerns dried seaweed supplied as agar raw material. Ask the supplier to distinguish it from extracted agar powder or a prepared food. Confirm the species, processing and suitability for human consumption when finding your commodity code. See seaweed and algae for the wider product family.

Specify the seaweed and extraction performance

Write the botanical species, harvest area, whole or ground form, washing method and any bleaching or chemical treatment into the purchase specification. Names such as Gelidium and Gracilaria identify different agar raw materials; a common name alone is a weak buying specification. Agree moisture, sand, salt, foreign matter, colour and packaging against an approved sample.

For extraction use, compare samples using your own extraction method and record recovered agar yield, gel strength and colour. For edible supply, food safety requirements apply. Check the species and processing against novel food status before ordering: novel foods need authorisation before sale in Great Britain. Ask a laboratory to propose relevant contamination tests rather than accepting an unrelated agar powder report.

Worked duty example

Illustrative example, not a quote: Illustrative order: 500 kg of whole dried agar seaweed fit for human consumption 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: compare the botanical name, appearance and supplier sample with the delivered seaweed; investigate mixed species or unexplained colour differences.

Cleanliness: draw samples from across the shipment and check for sand, shells, other seaweed, plastic and excessive salt deposits.

Condition: measure moisture against the agreed specification; check for mould, musty odours, damp liners and damaged bag seals.

Performance and records: repeat the agreed extraction trial and match bag batch markings to the sample records and laboratory reports. Use testing and certification support to agree the testing brief.

What goes wrong

Buying by dry weight alone can conceal excessive moisture, sand or salt, leaving less usable seaweed after washing. Mixed species and changes in washing or treatment can change extraction performance. Compare production samples with the approved material before shipment, then repeat the checks on arrival.

A report for extracted agar does not establish the condition of the seaweed being shipped. Keep the raw-material specification and extraction trial separate. Hold visibly mouldy or otherwise suspect edible lots for assessment: food must not be unsafe. Resolve organic paperwork with the broker before dispatch rather than relying on the supplier’s organic description.
