Sourcing molybdenum furnace boats from China

Zero duty and the waste-control check

Read from the UK Trade Tariff on 20 October 2026, heading 8102 covers molybdenum and its articles, including waste and scrap. Finished furnace boats should be assessed against the other-articles line, 8102 99 00 00. Sheet and unwrought material are separate lines. The table includes related inputs and scrap so that these are not described as finished boats.

The supplied tariff snapshot records 0% duty for goods from China across these lines, with no anti-dumping duty, countervailing duty or suspension recorded. It attaches import and export waste controls to the other-articles and scrap lines. England's official guidance says waste shipment controls apply only to waste. For a shipment from China, ask your customs broker to confirm whether the attached control requires documents or consent for the actual goods.

Confirm the commodity code using the material, manufacturing route and finished drawing. See the wider molybdenum guide for other forms. For the illustrative order, FOB and freight values are assumptions rather than a quotation; see UK import duty and VAT for the calculation method.

Boat geometry and furnace conditions

Specify the material grade, purity, density, oxygen content and manufacturing route. State whether the boat is folded from sheet or machined, and provide a drawing covering internal capacity, wall thickness, base flatness, corners, seams and handling features. Ask for batch-linked chemical analysis rather than a certificate covering an unspecified stock grade.

Give the supplier the furnace atmosphere, operating temperature, load material and support arrangement. Agree the surface finish and cleaning condition, and approve a sample in your own furnace before accepting repeat production. HSE says substances in articles may require UK REACH registration if intended to be released during use; review that point if the proposed design includes such a release.

Worked duty example

Illustrative example, not a quote: Illustrative order: 500 kg of finished molybdenum furnace boats for industrial stock under 8102 99 00 00, 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

Material: match batch identification to the certificate; check chemistry and density against the ordered grade, with independent testing for the initial delivery.

Geometry: measure wall thickness, internal dimensions, base flatness and seam position against the drawing; check fit on the actual furnace support.

Surface: inspect folded corners, machined edges and seams for cracks, burrs, laminations and oxidation; agree how questionable parts will be assessed.

Packing: check rigid support, separation between boats and the agreed protective sealing and desiccant. Use a written inspection brief to record acceptance criteria.

What goes wrong

A boat can match the outside dimensions while having the wrong internal capacity or a bowed base. Corners can crack during forming, and thin walls can be damaged when boats are nested for transport. Inspect the sample's working surfaces and support points, not just its overall length.

Poorly worked material can crack, low-density sintered parts can fail at temperature, and oxidation or chemistry outside the ordered grade can shorten service life. Keep the approved drawing, material certificate and furnace trial findings together so that a supplier cannot substitute a different material route without review.
