Sourcing enoki mushroom spawn from China

Enoki spawn: 0% duty

Read from the UK Trade Tariff on 29 September 2026, heading 0602 covers other live plants, roots, cuttings, slips and mushroom spawn. Enoki spawn falls within the mushroom-spawn line, 0602 90 10 00, carrying 0% duty for goods from China. The supplied tariff record shows no anti-dumping or countervailing duty and no suspension. The table shows product forms sharing this single tariff line.

The UK Trade Tariff attaches Veterinary control and Import control of organic products. Its application to the exact enoki spawn and medium could not be established from the official guidance reviewed; ask your customs broker to confirm the requirements before shipping. A business trading organic products must be certified by an approved UK organic control body. Confirm certificate-of-inspection coverage with that body; the exporter’s control body issues the certificate.

Provide the strain identity, intended propagation use, medium ingredients and packaging when confirming the commodity code. For the wider heading, see the shiitake mushroom spawn guide.

Specify the enoki strain and spawn medium

Ask for the scientific identity and strain designation, intended crop appearance, grain or sawdust medium, all supplements, and any animal-derived ingredients. Agree pack size, production-batch identification, storage conditions and the supplier’s usable-life guidance. Distinguish propagation spawn from a fruiting block when briefing the supplier.

Ask for a sample from the proposed production strain and test it in your own substrate and growing process. Record colonisation, contamination and fruiting results against the agreed sample. Request production and packing records through factory verification.

If the medium contains manure, obtain its processing details for the broker’s assessment. Official guidance prohibits importing unprocessed manure from outside the European Union into Great Britain, and manure imports require the relevant health certificate. Confirm how these rules apply to the complete spawn product before ordering.

Worked duty example

Illustrative example, not a quote: 2,000 bags of enoki mushroom spawn; illustrative order and values under 0602 90 10 00, invoiced at £6,000 free on board, with £900 of freight and insurance to the UK. The customs value is £6,900. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £6,900, so it is £1,380. 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: check strain designation, batch labels and medium ingredients against the order and approved sample.

Condition: check for unexpected coloured growth, wet patches, leakage, damaged seals and broken bottles.

Transport: compare temperature records and arrival condition with the supplier’s agreed storage and transport instructions.

Performance: retain batch samples for a grow-out trial and record colonisation and fruiting results. Arrange the checks using the quality inspection guide.

What goes wrong

A bag can look colonised yet perform poorly in the buyer’s substrate. Strain substitution, contamination, ageing and unsuitable transport conditions can undermine the crop. A photograph of white mycelium does not replace a grow-out trial.

An incomplete medium description leaves the broker unable to assess the tariff’s veterinary control. An organic claim also needs more than a supplier’s label. Resolve medium composition, organic certification and applicable border documents before dispatch.
