Sourcing wafer dicing machines from China

Duty on wafer dicing machines

Heading 8486 covers semiconductor manufacturing equipment and its parts. Semiconductor wafer dicing machines cut processed wafers into individual dies. The device-manufacturing line is the starting point for classification. The table also distinguishes neighbouring equipment categories; these are not alternative codes to choose solely because their duty matches.

Read from the UK Trade Tariff on 25 October 2026, all supplied lines carried 0% duty for goods from China. The supplied tariff data records no anti-dumping or countervailing duty, suspension or attached import control. Machinery safety obligations still apply.

Confirm the commodity code using the machine's function, process description and whether the shipment contains complete equipment or separate parts. See the semiconductor and display equipment guide for the wider heading.

Specify the wafer and the cutting process

State whether you need blade dicing or laser processing, and specify wafer material, diameter, thickness, coatings, mounting tape and frame. Agree cut depth, kerf width, edge chipping, die dimensions and throughput against your own samples. Include loading, alignment, recipe storage and the method for measuring acceptance results.

Match power, cooling water, drainage, compressed air and extraction interfaces to your site. Agree installation, operator training, software access and spare-part availability. Confirm the applicable conformity assessment, technical file, declaration and CE or UKCA marking requirements with the relevant authority. CE recognition continues in Great Britain. Request an English operating manual and evidence covering the machine's electrical, moving-part and laser hazards where applicable.

Worked duty example

Illustrative example, not a quote: 3 semiconductor wafer dicing machines; illustrative order only under 8486 20 00 00, invoiced at £450,000 free on board, with £15,000 of freight and insurance to the UK. The customs value is £465,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £465,000, so it is £93,000. 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

Sample cuts: inspect your wafer samples for chipping, cracks, incomplete separation and die damage; record results against the agreed acceptance criteria.

Motion and cutting system: check alignment, stage repeatability and spindle condition for blade machines, or focus and alignment for laser machines.

Safety and documents: check guards, interlocks and emergency stops; match the machine identity to its declaration, marking, manual and supporting safety documents.

Arrival and installation: inspect crate condition and shock indicators, check supplied accessories, then repeat the agreed cutting test after installation. Use a written quality inspection brief.

What goes wrong

A demonstration on the supplier's wafer can conceal poor results on your material or mounting tape. Edge chipping, die cracking, alignment drift and unsuitable cooling can make apparently separated dies unusable. Define acceptance around usable output and measured cut quality, rather than a demonstration video.

Transport can disturb alignment, while worn spindles or stages can undermine refurbished equipment. Missing software permissions, incompatible site connections and unavailable consumables can prevent commissioning. Agree the installed acceptance test, disclosed component condition and access to recipes and service information before shipment.
