Sourcing vision inspection systems from China

Duty and classification for vision inspection systems

Heading 9031 covers measuring or checking instruments not specified elsewhere. An optical inspection system may fit 9031 49 90 00, while semiconductor inspection and geometrical measurement have separate lines. The table shows possible classifications and separately supplied parts, not interchangeable codes for the same system. A camera alone does not settle the classification of a complete inspection station.

Read from the UK Trade Tariff on 30 September 2026, the selected lines carried 0% duty for goods from China; related test benches carried 2%. The supplied record lists no anti-dumping or countervailing duties or suspensions. It attaches fluorinated greenhouse gas import controls to 9031 80 80 00 and 9031 90 00 00. Confirm the requirement for the actual shipment with your customs broker.

Send the broker the inspection function, optical arrangement, handling equipment and supplied components to confirm the commodity code. For any pre-charged cooling equipment, establish whether gas quota rules apply: equipment requiring quota authorisations or delegations cannot be imported into Great Britain without enough cover. For camera selection within the wider product family, see industrial machine vision cameras.

Specify defects, lighting and the complete inspection cycle

Define the defects to detect, acceptable cosmetic variation, smallest relevant feature, field of view, working distance and required inspection speed. Supply representative good parts, defective parts and borderline samples. Agree missed-defect and false-reject acceptance criteria using samples kept separate from software setup.

Specify cameras, lenses, lighting geometry, fixtures, triggers, reject mechanism and connections to the production line. Test reflective, dark and translucent surfaces where relevant. List the computer, software licences, recipe editing, image storage, report exports and backup files. Agree who can restore the system after a computer replacement.

For powered inspection machinery, confirm applicable machinery, electrical safety and electromagnetic compatibility evidence and the appropriate CE or UKCA marking. Machinery must be safe before supply or use in Great Britain. For apparatus covered by electromagnetic compatibility rules, the manufacturer must supply relevant instructions in English. Match conformity documents to the complete supplied configuration.

Worked duty example

Illustrative example, not a quote: Illustrative order: four machine vision inspection stations under 9031 49 90 00, invoiced at £25,200 free on board, with £6,000 of freight and insurance to the UK. The customs value is £31,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £31,200, so it is £6,240. 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

Detection: run agreed good, defective and borderline samples without changing settings; record missed defects, false rejects and saved images against the acceptance criteria.

Handling: verify triggering, part positioning, inspection speed and physical rejection; check that the recorded result belongs to the part actually rejected.

Software: load and back up inspection recipes, export images and results, restart the system and demonstrate purchased functions on the buyer's computer without the supplier's account.

Arrival and documents: check lens mounts, lighting brackets, fixtures and connectors for movement or damage. Match equipment identity to conformity records and English instructions, then repeat acceptance checks after installation. Agree these checks through the inspection guide.

What goes wrong

A demonstration using clean, carefully positioned samples can hide failures on real production parts. Reflections, surface finish, vibration and changing ambient light can alter results. Validate with representative variation and retained defect samples, then repeat the agreed test under the buyer's installation conditions.

Reject timing can send a good part to the reject bin while the defective part continues downstream. Software may also depend on the supplier's account or omit editable recipes. Include the complete inspection and rejection cycle, licence access and recovery files in acceptance.
