Sourcing Penicillium cultures from China
Penicillium cheese-ripening cultures from China carry 0% UK duty under the non-pathogenic culture line. Unsafe food cannot be sold, and the tariff attaches veterinary and animal-health-certificate controls whose application needs checking. Cambridge China Bridge sources Penicillium cheese-ripening cultures.
Duty and import-control checks
Heading 3002 includes cultures of micro-organisms, excluding yeasts, alongside blood products, vaccines and cell cultures. For non-pathogenic Penicillium cheese-ripening cultures, the relevant candidate is 3002 49 00 20. The table describes buying variants under the same commodity line, rather than separate tariff subdivisions. For the wider culture family, see mould starter cultures.
Read from the UK Trade Tariff on 5 October 2026, the culture line carries 0% duty for goods from China, with no anti-dumping or countervailing duty and no suspension listed. The tariff attaches Veterinary control and Animal Health Certificate measures. The importer should confirm their application to the exact Chinese formulation with their customs broker, including whether any animal-derived carrier changes the required documents.
Give the broker the organism identity, intended cheese-making use, complete carrier composition and packaging details to confirm the commodity code. The published animal-derived starter-culture authorisation lists Australia, Canada, New Zealand and USA as origins. China is outside that listed route; ask the animal import authority to confirm whether another route exists before ordering such a formulation.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Non-pathogenic Penicillium cultures for white-rind cheese | 3002 49 00 20 | 0% | None |
Specify the strain and cheese-ripening result
Specify the species and strain identity, white-rind or blue-cheese application, culture format and carrier ingredients. Agree an activity test, dosing instructions, storage conditions and remaining shelf life on arrival. Ask for batch-specific identity, purity and contamination results, with test methods and agreed acceptance criteria rather than a generic description of cheese mould.
Trial the culture in your own milk and ripening process. Compare rind coverage or internal veining, flavour, unwanted pigmentation and consistency against an agreed reference batch. Ask for evidence supporting the exact strain's food use and assess novel-food status. Unsafe food cannot be placed on the market; a product that qualifies as a novel food needs authorisation before sale in Great Britain.
Worked duty example
Illustrative example, not a quote: Illustrative order: sealed freeze-dried culture sachets for a small cheesemaker under 3002 49 00 20, invoiced at £4,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £5,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,500, so it is £1,100. 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.
Inspection checklist
Identity: match the strain designation and batch on sachets, cartons and analysis documents to the purchase specification.
Activity: review the batch activity result and test a retained arrival sample in the agreed cheese-making process before using the batch throughout production.
Transport: compare temperature records with the supplier's stated storage conditions and stability evidence; investigate excursions before accepting the goods.
Packs and carriers: check seals, moisture ingress, caking, expiry and the complete carrier declaration, including any milk-derived ingredients; retain supplier and customer batch records.

What goes wrong
A culture can have the expected species name yet give the wrong rind, veining or flavour because the strain or application differs. Moisture ingress and unsuitable transport conditions can reduce activity. A certificate describing the supplier's usual product gives little assurance about the delivered batch. Set measurable acceptance criteria and keep an approved sample for comparison.
An animal-derived carrier can leave the import route unresolved even when duty is zero. Do not assume the published starter-culture authorisation covers China. Obtain a formulation-specific answer before dispatch, and keep suspect batches separate while identity, activity and transport records are reviewed.

Frequently asked questions
What is the UK import duty on Penicillium cheese cultures from China?
The supplied tariff reading lists 0% duty under 3002 49 00 20, with no anti-dumping or countervailing duty and no suspension. Veterinary and animal-health-certificate controls are attached.
Can I import cheese cultures containing a milk carrier from China?
Do not assume the published animal-derived starter-culture authorisation covers China: its listed origins exclude China. Ask the animal import authority and your customs broker to confirm the exact formulation's route.
Does a Penicillium cheese culture need novel-food authorisation?
Assess the exact product's status rather than relying on its genus name. If it qualifies as a novel food, authorisation is needed before it can be placed on the Great Britain market.
What should I check when cheese cultures arrive?
Match strain and batch documents, inspect seals and moisture damage, review transport records against supplier conditions, and trial an arrival sample for the agreed ripening result.
