Duty and organic import controls

Read from the UK Trade Tariff on 30 September 2026, heading 2102 covers active and inactive yeasts, other dead single-cell micro-organisms and prepared baking powders. Osmotolerant baker's yeast falls within the active baker's yeast family: dried yeast under 2102 10 31 00 and other baker's yeast under 2102 10 39 00. Both carry 0% duty for goods from China, with no listed anti-dumping or countervailing duty and no suspension.

The tariff attaches import control of organic products to both lines. For organic yeast imported from China into 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 exporter’s control body issues the certificate. Confirm the shipment arrangements with your customs broker.

The table repeats the relevant codes for different supply formats; pack size does not create a separate tariff line. Confirm the commodity code from the product's form and intended use. For the wider yeast family, see instant dry baker's yeast. Confirm with HMRC whether yeast sold as a food ingredient qualifies for VAT zero-rating, and consult the duty and VAT guide.

Specify performance in sweet dough

Specify osmotolerant baker's yeast for your actual sweet-dough recipe. Give the factory the flour, sugar, salt and fat proportions, yeast dosage, mixing method, dough temperature and proofing conditions. Agree a dough-rise test against an approved sample, with the recipe and method recorded. A general activity result does not show how the yeast performs in your dough.

Agree dried or fresh form, granule characteristics where applicable, dry matter, microbiological checks, pack format, storage instructions and remaining shelf life on arrival. Request a batch certificate of analysis and retain samples. Importers must ensure that goods are safe and legal before import into Great Britain. For retail packs, confirm the applicable food-information requirements, including the food-business address for sale in Great Britain, with the relevant food authority; use the site's published yeast guide as a checklist.

Worked duty example

Illustrative example, not a quote: A pallet of vacuum-packed osmotolerant dry baker's yeast; illustrative order and values under 2102 10 31 00, invoiced at £2,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £3,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,500, so it is £700. 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

Performance: compare production-batch samples with the approved yeast in the agreed sweet-dough recipe; record rise and baked results under matching conditions.

Batch quality: match the certificate of analysis to carton and pack batch marks; check dry matter and the agreed microbiological results.

Packing: inspect vacuum retention, seals, damaged packs, moisture ingress and caking; review available transport temperature records.

Labels and dates: check product identity, ingredients, net quantity, date marks, storage instructions and the food-business address; compare remaining shelf life with the purchase specification.

What goes wrong

A sample can perform well in plain dough while the delivered batch disappoints in the buyer's sweet recipe. An undefined test method makes disputes harder to resolve. Approve the recipe-based test before ordering and compare arrival samples with retained production samples.

Leaking packs, moisture and heat in transit can reduce activity. Short remaining shelf life leaves less time to use the stock. Record pack damage and batch details before opening or mixing affected goods, and use the quality inspection guide to organise the checks.

Frequently asked questions

What is the UK import duty on osmotolerant yeast from China?

Both dried baker's yeast under 2102 10 31 00 and other baker's yeast under 2102 10 39 00 carry 0% duty in the supplied tariff reading, with no listed anti-dumping or countervailing duty.

How do I check whether yeast suits sweet dough?

Test the production batch in your own recipe against the approved sample. Keep yeast dosage, dough temperature, mixing and proofing conditions consistent.

What paperwork does organic yeast from China need?

For 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.

Why does imported osmotolerant yeast lose activity?

Heat, leaking packs and moisture can reduce activity. Inspect seals and vacuum retention, review transport records and repeat the agreed dough-rise test on arrival.
