Sourcing Zirconium Nitride Powder from China
Zirconium nitride powder from China carries 4% UK duty under 2850 00 20 90, with no applicable suspension or listed trade remedy. UK REACH registration arrangements and chemical classification need checking before import and supply in Great Britain. Cambridge China Bridge sources zirconium nitride powder.
Zirconium nitride powder: 4% duty
Read from the UK Trade Tariff on 1 October 2026, heading 2850 covers hydrides, nitrides, azides, silicides and borides, excluding compounds that are also carbides. Zirconium nitride powder falls within the residual hydrides and nitrides line, 2850 00 20 90. The table shows powder specifications within this same line, rather than separate tariff subdivisions.
The supplied tariff data shows 4% duty for goods from China and no listed anti-dumping or countervailing duty. The suspension on this line names lithium aluminium hydride preparations and qualifying titanium nitride, not zirconium nitride. The tariff also attaches import and export waste controls. For waste powder from China entering England under notification controls, shipment can begin only after consent from the Environment Agency and the other competent authorities involved. Confirm the applicable waste requirements with your customs broker.
Confirm the composition and supplied form through finding your commodity code. A blended preparation or finished component needs its own classification check. See the silicon nitride powder guide for the wider heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Zirconium nitride powder | 2850 00 20 90 | 4% | None |
Specify phase, impurities and particle distribution
Specify zirconium nitride as the required compound, its phase composition, nitrogen content, purity basis and limits for oxygen, carbon and metallic contamination. Agree the test methods and whether the certificate reports measured results or specification limits. State whether surface treatment, binders or other additions are acceptable.
Define the particle size distribution, measurement method and sample preparation, including how agglomerates are dispersed. Agree moisture limits, sealed packing and batch traceability. Retain an approved sample for comparison with production material.
For Great Britain, check the UK REACH registration route before ordering. Confirm with HSE or your customs broker whether registration applies to your annual imports and whether an only representative arrangement is available for your supply. Before sale, check chemical classification, labels and packaging. Obtain the safety data sheet and confirm with HSE when it should be provided.
Worked duty example
Illustrative example, not a quote: Illustrative order: 25 kg of zirconium nitride powder under 2850 00 20 90, invoiced at £15,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £17,000. Duty at 4% is £680. Import VAT at 20% is charged on the customs value plus duty, £17,680, so it is £3,536. Import taxes total £4,216; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £680 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: compare batch certificates with independent phase and composition testing, checking for unwanted oxide or carbide phases.
Particle size: use the agreed measurement and dispersion method; compare the distribution and agglomeration with the approved sample.
Packing: check seals, moisture protection, container condition, net weight and matching batch references.
Documents: match the analysis certificate and safety data sheet to the supplied powder; check registration arrangements and appropriate hazard labels before release. Use the quality inspection guide to define the inspection scope.

What goes wrong
A purity claim can conceal different reporting bases or omit oxygen and carbon. A nominal particle size can hide coarse agglomerates, while a certificate from the sample batch may be reused for production. These differences can make the delivered powder behave differently in the buyer's process.
Agree acceptance limits and sampling before shipment. Keep suspect batches separate when seals are damaged, the powder is caked or test results disagree with the certificate. Settle the chemical and transport classification from the actual material rather than assuming every nitride has the same hazards.

Frequently asked questions
What is the UK import duty on zirconium nitride powder from China?
The supplied tariff data shows 4% under 2850 00 20 90, with no applicable suspension and no listed anti-dumping or countervailing duty.
Does the titanium nitride suspension cover zirconium nitride?
No. Zirconium nitride is not named in the suspension attached to this commodity line. Budget for 4% duty.
Do I need UK REACH registration for zirconium nitride powder?
For Great Britain, check registration arrangements when annual imports of the substance reach one tonne. Confirm whether your imports are covered through an applicable only representative arrangement.
What should I test before accepting zirconium nitride powder?
Check phase identity, nitrogen content, oxygen and carbon impurities, particle size distribution and agglomeration against agreed methods and limits. Match the results to the delivered batch.
