Sourcing measuring microscopes from China

UK duty on measuring microscopes

Heading 9011 covers compound optical microscopes, including those for photomicrography and microprojection, and their parts and accessories. Select the line from the actual optical construction and functions, rather than the supplier's description of a measuring microscope. Confirm the commodity code with the specification and supporting photographs. See the wider microscope guide for the other product families.

Read from the UK Trade Tariff on 1 October 2026, all supplied lines carried 0% duty for goods from China. The supplied records list no anti-dumping or countervailing duties and no suspensions. Import VAT is normally 20%; see the import duty and VAT guide.

The supplied tariff records attach a control labelled DCMS Export Licence. Official guidance says there are no licensing requirements for importing objects of cultural interest into Great Britain. If buying an antique instrument or planning onward export, ask your customs broker to confirm how the listed control applies to the transaction.

Specify the measurement system

Define the workpieces and features to measure, required measurement accuracy, repeatability, stage travel, working distance and illumination. Identify whether readings come from an eyepiece scale, stage readout or camera software. Agree a demonstration using your reference artefact, including measurements at different stage positions and after reversing the direction of travel.

Ask for calibration results identifying the instrument, reference artefact, method and measurement uncertainty. Specify optical magnifications, reticle design, stage load, focusing mechanism and the supplied measuring accessories. For camera-based systems, agree how calibration is stored for each optical setting and whether the supplied software can export usable results.

For mains-powered illumination, confirm applicable electrical safety evidence, UKCA or CE marking, declaration of conformity and UK importer identification requirements for the Great Britain market with the relevant authority. Also confirm whether electromagnetic compatibility, restricted substances and electrical waste obligations apply. For equipment covered by the electrical safety regulations, the importer must ensure that instructions are in easily understandable English. Match the evidence to the exact instrument and power supply.

Worked duty example

Illustrative example, not a quote: 150 basic optical measuring microscopes for a business distributor; illustrative only under 9011 80 00 00, invoiced at £27,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £28,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £28,500, so it is £5,700. 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

Measurement: compare readings with an agreed reference scale across the usable stage travel, repeat measurements and check readings after changing the direction of movement.

Optics: check that the reticle and workpiece can be focused together, edges remain clear across the field, and changing magnification gives the expected measurement results.

Mechanics: check stage movement, backlash, locks and focus drift under the intended workpiece load; confirm that the workpiece fixture holds position.

Documents and packing: match calibration results and electrical documents to the supplied model, test illumination and readouts, and check that the stage is secured against transit movement. Use the inspection guide to agree acceptance checks.

What goes wrong

A sharp image can still produce unreliable measurements. Backlash changes readings when the stage reverses, a reticle gives inconsistent edge alignment, or camera calibration is used with the wrong optical setting. A readout's resolution alone does not establish measurement accuracy.

Loose stages and heavy fixtures can disturb alignment during transport. Approve a sample using representative workpieces, retain its measurement results and repeat the agreed checks on arrival. Require the supplier to explain any difference before accepting the shipment.
