Sourcing tantalum evaporation pellets from China

Duty and classification for tantalum pellets

Read from the UK Trade Tariff on 1 October 2026, heading 8103 covers tantalum and articles thereof, including waste and scrap. All listed lines carry 0% duty for goods from China, with no listed anti-dumping or countervailing duties and no suspensions. The table includes pellet classification candidates, manufacturing feedstock and waste; these are different goods.

The tariff attaches import and export waste controls to every listed line. Waste shipment controls apply only where the material is waste. For a shipment from China, ask your customs broker to confirm the material's waste status and the applicable requirements, particularly for used evaporation charges or recovery material.

Do not select a code solely from the name 'evaporation pellets'. Obtain the manufacturing route, physical form and intended supply condition, then confirm the commodity code. For wider tantalum coverage, see the tantalum sputtering targets guide.

Pellet purity, shape and evaporation trials

Specify tantalum purity, the impurities included in that calculation, and separate acceptance limits for oxygen, nitrogen, carbon and metallic contaminants. State whether the pellets are cut from worked rod, sintered or made by another route. Agree diameter, length, shape, dimensional tolerances, cleaning and packaging with the factory.

Request a certificate of analysis for the actual batch, including test methods and reporting limits. Agree a retained sample and trial the material in your evaporation equipment before accepting a production batch. Define acceptance for melting behaviour, spitting and deposited-film contamination.

For Great Britain, assess whether importing the material as a new substance requires UK REACH registration. Your business must identify and manage risks from substances it places on the market. Settle these questions alongside the specification rather than relying on a supplier's general compliance statement.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2 kg of finished tantalum evaporation pellets, classification assumed under 8103 99 90 00, invoiced at £3,600 free on board, with £800 of freight and insurance to the UK. The customs value is £4,400. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,400, so it is £880. 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

Chemistry: match the batch certificate to the sealed packs and commission independent analysis against the agreed impurity limits.

Geometry: measure sampled pellet diameters and lengths against the drawing; check for oversized pieces, irregular cuts and loose fines.

Cleanliness: inspect for oil, machining residue, loose particles and damaged packaging; keep samples sealed until testing.

Traceability: reconcile batch identities, pack weights and retained samples with the order. Include these checks in the inspection brief.

What goes wrong

A purity statement can leave important impurities outside the calculation. A certificate from another batch, mixed production lots or cleaning residue can also defeat an otherwise clear specification. Compare the analysis basis and batch identity, then use a process trial to assess the material in your equipment.

Pellets outside the agreed dimensions can be unsuitable for the charging arrangement. Keep rejected material separate while investigating. If a supplier offers used charges or recovery material instead of new pellets, confirm its condition and waste-control position before shipment.
