Sourcing niobium rods from China

Duty and classification for niobium rods

Heading 8112 covers niobium and other named metals and their articles. For rods, the supplied facts distinguish niobium-titanium alloy bars and rods under 8112 99 50 10 from other niobium articles under 8112 99 50 90. The table separates bar and rod descriptions within these same commodity lines. See the wider minor-metals guide.

Read from the UK Trade Tariff on 2 October 2026, both rod lines carry 0% duty for goods from China, with no listed anti-dumping or countervailing duty, suspension or attached control. Import VAT at 20% still applies. The separate unwrought-niobium line has an attached waste import control; if that line is proposed, confirm the requirement with your customs broker.

Confirm the commodity code using composition, manufacturing process and supplied form. Do not choose the unwrought-niobium line merely because the supplier calls its product raw material. Keep the drawing, composition certificate and process description available for the classification review.

Specify composition and rod condition

State whether you need unalloyed niobium or niobium-titanium alloy. Agree the chemistry limits, including interstitial impurities, and the laboratory method used to check them. Specify diameter, length, straightness, machining allowance, surface finish and delivery condition. Ask for a mill certificate linked to the supplied heat and a retained sample for independent analysis.

UK REACH generally covers chemical substances on their own, in mixtures or in articles. Review your position before importing or selling the material, using the intended use and supplied form rather than assuming that a rod description settles chemical compliance.

Worked duty example

Illustrative example, not a quote: 200 kg of niobium rods, illustrative order only under 8112 99 50 90, invoiced at £30,000 free on board, with £800 of freight and insurance to the UK. The customs value is £30,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £30,800, so it is £6,160. 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 heat certificate to the ordered composition and arrange independent analysis against the agreed impurity limits.

Dimensions: measure diameter along the rod, check length and straightness, and confirm sufficient machining allowance against the drawing.

Surface: inspect for seams, cracks, deep scratches and embedded contamination; agree acceptance criteria before shipment.

Traceability and packing: match bundle labels to heat certificates, check quantity and weight, and inspect supports and wrapping for movement or bending damage.

What goes wrong

An alloy supplied against an unalloyed-niobium order can pass a visual check. A certificate without matching heat identification leaves composition uncertain. Bent rods, deep surface marks or inconsistent diameter can consume the machining allowance and leave insufficient material for the finished part.

Agree rejection criteria and sampling before ordering. Hold mismatched or damaged material apart while the supplier and laboratory investigate. Use quality inspection to check the delivered rods against the purchase specification.
