Sourcing unworked snail shells from China

Zero duty, with controls depending on use

Heading 0508 covers mollusc shells that are unworked or simply prepared but not cut to shape, together with their powder and waste. This guide focuses on whole unworked snail shells. The table separates decorative and craft uses under the same code. See the shells and coral guide for the wider heading.

Read from the UK Trade Tariff on 29 September 2026, the relevant lines for goods from China carry 0% duty throughout, with no anti-dumping or countervailing duty and no suspension recorded. Empty shells for food use fall under 0508 00 90 10; shells retaining tissue or flesh are described under 0508 00 90 20; other shells are under 0508 00 90 90.

The tariff attaches veterinary control to the food-use and flesh-bearing lines, organic import control to all relevant lines, CITES import control to the other-shells line and CITES export control to all relevant lines. For Chinese consignments, ask your customs broker to confirm the veterinary and organic requirements for the actual goods; do not assume every empty shell needs the same documents. Confirm the commodity code against species, preparation, retained tissue and intended use.

Specify species, empty cavities and shell grading

Specify the scientific species name, collection or farming origin, intended use and whether every shell must be completely empty. Agree shell length, opening size, natural colour variation, intact lips and tips, acceptable chips and packing against a retained sample. Describe washing and drying, and exclude undisclosed paint, lacquer, fillers or repairs.

For CITES-listed specimens moving into or out of Great Britain, permits are required. This can include animal parts such as shells. Check the species with APHA and contact the Chinese management authority for the corresponding documents before arranging shipment.

If the consignment falls within the animal-by-product import route, official guidance requires advance notification through the import notification system and entry through an approved border control post. Ask your broker and APHA to establish the applicable route and whether the Chinese origin and processor are eligible before ordering.

Shells intended to contact food need to be safe and suitable for that use. Ask for evidence covering the proposed food, heating and cleaning conditions, including any treatment residues. Decorative appearance alone does not demonstrate suitability for serving food.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2 tonnes of empty unworked snail shells for craft supplies under 0508 00 90 90, invoiced at £1,500 free on board, with £900 of freight and insurance to the UK. The customs value is £2,400. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £2,400, so it is £480. 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: compare species, origin records, batch marks and declared use with the purchase specification; investigate mixed species.

Cleanliness: inspect cavities across the shipment for retained flesh, soil, foreign matter, damp, mould and odour; compare cleaning records with the agreed process.

Integrity: check opening size, grading, chipped lips, broken tips, cracks and concealed repairs against the retained sample.

Packing: inspect cushioning, carton strength and crushed shells at carton bottoms; reconcile contents and batch marks with shipment documents. Use the inspection guide to brief checks before dispatch.

What goes wrong

An apparently empty shell can retain tissue deep inside its spiral. Damp packing encourages odour, while loose bulk packing leaves chipped openings and broken tips. Mixed sizes can make shells unsuitable for a buyer's serving trays or craft designs. Agree cavity checks, grading and protective packing before production.

A supplier may describe the goods only as natural shells, leaving species, retained flesh and food use unresolved. These details affect the tariff line and control checks. Resolve them before shipping, and keep decorative stock separate from stock assessed for food use.
