Sourcing tantalum carbide powder from China
Tantalum carbide powder from China carries 4% UK duty under 2849 90 50 10, with no anti-dumping duty or suspension in the supplied tariff record. Chemical supply rules require correct labelling and packaging before sale in Great Britain. Agree carbon content, impurities and particle size before ordering.

Tantalum carbide powder: 4% duty
Read from the UK Trade Tariff on 1 October 2026, heading 2849 covers carbides, whether or not chemically defined. Tantalum carbide powder falls within the tantalum line, 2849 90 50 10, carrying 4% duty for goods from China. The record lists no anti-dumping or countervailing duty and no suspension. The powder descriptions in the table share this tariff line.
The tariff attaches import and export waste controls. Environment Agency guidance for England says waste shipment controls apply only where the material is waste. For recovered powder or residues offered from China, ask your customs broker to confirm waste status and the applicable notification, consent or prohibition requirements before shipment.
Confirm the composition and physical form against the commodity code guide, especially where the offer includes mixed carbide powder or sintered parts. For wider heading context, see the niobium carbide powder guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Tantalum carbide powder | 2849 90 50 10 | 4% | None |
Specify carbon, impurities and particle size
Specify tantalum carbide powder rather than tantalum metal powder or a tantalum-niobium carbide blend. Agree tantalum carbide content, total carbon, free carbon, oxygen and limits for metallic impurities. Ask for a batch certificate of analysis identifying the test methods and reporting actual results against your agreed limits.
State the particle size distribution and measurement method, including how the laboratory disperses agglomerates before testing. Agree moisture acceptance, sealed inner packaging, batch identification and a retained sample. Trial the sample in your intended mixing and sintering process before accepting bulk material.
Check the UK REACH registration position with HSE before ordering, including whether registration coverage or an only representative arrangement is appropriate for your import volume and supply chain. Before placing chemicals on the Great Britain market, the supply chain must ensure correct labelling and packaging. Ask for the safety data sheet and review the classification for the actual powder supplied.
Worked duty example
Illustrative example, not a quote: Illustrative order: 25 kilograms of tantalum carbide powder; FOB and freight values are illustrative under 2849 90 50 10, invoiced at £30,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £32,500. Duty at 4% is £1,300. Import VAT at 20% is charged on the customs value plus duty, £33,800, so it is £6,760. Import taxes total £8,060; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,300 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the order, container labels and certificate to tantalum carbide powder and the same batch; check that a mixed carbide has not been substituted.
Chemistry: independently check total carbon, free carbon, oxygen and the agreed impurities against the batch certificate.
Particle size: test representative samples using the agreed dispersion and measurement method; inspect for coarse particles and hard agglomerates.
Packaging: check seals, inner liners, moisture damage, leakage and batch identification before opening; retain samples for later comparison.

What goes wrong
A matching average particle size can hide a coarse tail or agglomerates. Carbon and oxygen results can differ between the approved sample and production batch, while an unspecified blend can change your formulation. These are reasons to compare delivered material with the retained sample and run a process trial.
A generic certificate does not establish the contents of the delivered batch. Agree sampling, laboratory methods and acceptance criteria before dispatch, using the quality inspection guide. Keep any material with mismatched documents, broken seals or failed results separate while you investigate.

What is the UK import duty on tantalum carbide powder from China?
The supplied tariff record gives 4% under 2849 90 50 10, with no anti-dumping or countervailing duty and no suspension. It was read on 1 October 2026.
Does tantalum carbide powder need UK REACH registration?
Before ordering, confirm with HSE whether your annual import volume and supply arrangements require UK REACH registration coverage or an only representative arrangement.
What should a tantalum carbide powder specification include?
Agree identity, tantalum carbide content, total and free carbon, oxygen, metallic impurities, particle size distribution, test methods and sealed packaging.
How do I check tantalum carbide powder on arrival?
Match batch labels to the certificate, inspect seals and moisture damage, and test representative samples for chemistry and particle size using the agreed methods.
