Sourcing rotary microtomes from China

Duty on rotary microtomes

Heading 9027 includes microtomes alongside analytical and measuring instruments. The supplied tariff places microtomes, parts and accessories under 9027 90 00 00. The table shows different purchase types within that same commodity line, rather than separate tariff subdivisions.

Read from the UK Trade Tariff on 17 October 2026, this line carried 0% duty for goods from China. The supplied record lists no anti-dumping or countervailing duty, suspension or attached import control for this line. Import VAT is normally 20%; see import duty and VAT.

Confirm the commodity code against the complete instrument or separately supplied part. For the wider medical-device context, see medical instruments and devices. That guide covers a different heading; do not transfer its codes to microtomes.

Specify the cutting mechanism and intended use

State whether you need manual or motorised operation, the specimen and embedding material, section-thickness settings, trimming controls, specimen travel and retraction. Agree the cassette clamp, blade format, blade-holder adjustment, waste tray and cleaning method. Request cutting trials using representative blocks, with the settings recorded.

Obtain the manufacturer's intended-use statement before ordering. General laboratory products are not in vitro diagnostic devices unless specifically intended by their manufacturer for diagnostic examination of human samples within the diagnostic definition. If the model is a medical device, registration with the MHRA is required before placement on the Great Britain market, and an overseas manufacturer must appoint a UK Responsible Person.

For a motorised model falling within machinery supply rules, new machinery placed on the Great Britain market must bear UKCA or CE marking, come with a declaration of conformity and have instructions in English. Ask for documents matching the supplied model and use testing and certification to organise the evidence review.

Worked duty example

Illustrative example, not a quote: Illustrative order: a small batch of rotary microtomes under 9027 90 00 00, invoiced at £10,000 free on board, with £900 of freight and insurance to the UK. The customs value is £10,900. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £10,900, so it is £2,180. 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

Cut quality: cut representative embedded blocks and compare the sections with the approved sample. Look for chatter, compression, scoring and inconsistent feed.

Clamps and holder: check cassette retention, specimen orientation, blade seating and adjustment. Confirm that the clamps and holder remain secure during cutting.

Safety controls: check the blade guard, handwheel lock and, where fitted, stopping controls against the agreed specification and operating instructions.

Arrival condition: inspect the base, specimen feed and accessories for transit damage. Match model identification and documents to the order, then repeat the cutting trial after unpacking. See quality inspection.

What goes wrong

A display showing the requested thickness does not prove that the machine produces consistent sections. Chatter or compression can arise from the cutting setup as well as the mechanism. Compare blade seating, clamp security and block preparation before accepting the instrument or blaming the feed.

A research-use quotation can become unsuitable when the supplied instructions describe diagnostic use. Resolve the intended use and applicable compliance route before ordering. Also confirm replacement clamps, compatible blade holders and servicing arrangements; a visually similar accessory may not fit.
