Sourcing battery anode graphite from China

Zero duty on synthetic graphite anode powder

Heading 3801 covers artificial graphite, colloidal graphite and certain carbon preparations. This guide concerns dry synthetic graphite powder for battery anodes. Powder containing not more than 0.05% ash by weight falls under 3801 10 10 00; other artificial graphite powder falls under 3801 10 90 85. The table separates fine and coarse buying grades under these shared codes; particle size does not create additional tariff lines.

Read from the UK Trade Tariff on 1 October 2026, both relevant lines carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspension or attached import control. Chemical obligations still need checking separately. For the other products in this heading, see our artificial and expandable graphite guide.

Confirm the commodity code using the manufacturing route, composition, physical form and measured ash content. Identify any coating or added material before classification. Natural graphite belongs to a different heading. See UK import duty and VAT for the calculation method.

Specify the powder for your anode process

Specify synthetic origin, fixed carbon, ash, moisture, sulphur and iron. Agree the particle size distribution and test method, specific surface area and tap density. Record whether the powder is coated and obtain its composition. Set acceptance criteria using your own electrode formulation and cell test, including first-cycle capacity. A supplier's capacity result is difficult to compare unless the test conditions match.

For supply into Great Britain, importers are responsible for chemical hazard classification, and the supply chain must ensure correct labelling and packaging before placing chemicals on the market. Check UK REACH obligations against the substance identity and annual import volume; some provisions apply at one tonne per year or more. A safety data sheet is required if a hazardous chemical is supplied for workplace use. Ask for safety information and plan dust-controlled handling.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of synthetic graphite anode powder in bulk bags under 3801 10 90 85, invoiced at £64,000 free on board, with £2,400 of freight and insurance to the UK. The customs value is £66,400. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £66,400, so it is £13,280. 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 the bag labels, batch references and manufacturing records against the agreed synthetic grade and any declared coating.

Purity: compare independent ash, moisture, iron and sulphur results with the batch certificate and purchase specification.

Powder behaviour: check particle size distribution, specific surface area and tap density; test a retained sample in your electrode formulation and cell.

Arrival condition: check bag seals, tears, moisture, caking and contamination before releasing stock. Keep samples linked to each batch.

What goes wrong

A powder can meet the supplier's headline purity figure yet fail your anode process. Ash or iron exceeds the certificate, particle size drifts between batches, or natural and blended graphite is supplied as synthetic. Moisture and contamination introduced during packing can also spoil an otherwise acceptable batch.

Approve samples through your own cell test and compare delivered batches with the approved material. Do not release stock solely on the factory certificate. Agree sampling and independent checks through our testing and certification service.
