Sourcing lead battery-grid casters from China

UK duty on lead battery-grid casting machines

Heading 8454 covers converters, ladles, ingot moulds and casting machines used in metallurgy or metal foundries, plus parts. This guide concerns machines that cast lead-alloy battery grids, their casting-machine parts and associated ladles or ingot moulds. See the wider die-casting and foundry equipment guide for the rest of the heading.

Read from the UK Trade Tariff on 1 October 2026, all listed lines carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions or attached import controls. Import VAT is separate from customs duty.

The casting method determines whether a machine belongs in the pressure-casting or other-casting line. Send the operating description, drawings and shipment contents to your customs broker and confirm the commodity code. Grid moulds are classified separately under heading 8480; do not assume every item supplied with the machine belongs under its code.

Specify the grid, alloy and casting process

Give the factory your grid drawing, including overall dimensions, rib pattern, lug position, thickness, weight and agreed tolerances. Specify the lead-alloy composition, gravity or pressure casting, mould heating and cooling, metal delivery, grid removal and trimming. Agree how output and reject rates will be measured using your alloy and grid design.

Define the supply boundary: casting machine, moulds, lead pot, transfer equipment, extraction connections, cooling equipment and controls. Confirm power supply, utility connections, cleaning access, lifting points, spare wear parts, commissioning and training. Use factory verification to check the maker's workshop and experience with comparable grid equipment.

Confirm applicable essential machinery health and safety requirements for machines placed on the Great Britain market with the relevant authority. New machines need CE or UKCA marking, a declaration of conformity and English instructions. HSE tells employers to keep lead-exposure controls in good working order and consult an appointed doctor about appropriate medical surveillance. Agree extraction arrangements and safe access for cleaning before approving the layout.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2 replacement casting-head assemblies for a battery-grid workshop under 8454 90 00 00, invoiced at £28,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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

Grid trial: witness casting with the agreed alloy and mould; measure grid dimensions, weight and flatness, and inspect ribs and lugs for incomplete filling, cracks, flash and distortion.

Metal handling: check temperature control, feed consistency, splash protection, extraction connections and access for removing dross; inspect cooling and hydraulic circuits for leaks.

Safety and documents: test guards, interlocks and emergency stops; match the machine identity to its declaration, marking, English instructions, wiring diagrams and spare-parts list.

Arrival: compare delivered assemblies with the packing list; inspect mould faces, alignment, connectors and corrosion protection, then repeat the agreed acceptance trial after installation. Plan these checks through quality inspection.

What goes wrong

A demonstration using a different alloy or simpler grid can hide filling problems. Unstable metal delivery or mould temperature can leave incomplete ribs, excess flash or distorted grids. Count acceptable grids rather than machine cycles, and retain trial samples with the operating settings.

Installation can stall when cooling connections, extraction interfaces, electrical drawings or replacement components are missing. Write these into the supply scope and check them before shipment. On arrival, resolve transport damage and connection mismatches before running the casting trial.
