Sourcing biological microscopes from China
Biological compound microscopes from China pay 0% UK duty across the relevant codes. Mains-powered models need electrical safety evidence, CE or UKCA marking and a declaration of conformity for sale in Great Britain. Specify optical performance and inspect alignment after transport. Cambridge China Bridge sources biological compound microscopes.
0% duty on biological compound microscopes
Read from the UK Trade Tariff on 1 October 2026, heading 9011 covers compound optical microscopes, including those for photomicrography, cinephotomicrography or microprojection. The relevant biological microscope and parts entries carry 0% duty for goods from China. The supplied tariff record shows no anti-dumping or countervailing duty and no suspensions.
The UK Trade Tariff attaches a DCMS Export Licence measure to these entries. Official guidance states that importing objects of cultural interest into Great Britain has no licensing requirements. Ask your customs broker to confirm how the attached measure should be handled for your shipment from China, particularly if buying used or historic instruments.
Confirm the commodity code against the instrument's functions and supplied configuration. Objectives and eyepieces are shown separately in the table but share the parts and accessories code. See the wider microscope guide for the other product families within this heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Biological compound microscopes, other than photomicrographic models | 9011 80 00 00 | 0% | None |
| Biological microscopes for photomicrography | 9011 20 90 00 | 0% | None |
| Objectives for biological compound microscopes | 9011 90 00 00 | 0% | None |
Specify the slide-viewing system
State whether the optical system is finite or infinity corrected, the objective grade and magnifications, eyepiece field number and observation head. Specify the condenser, transmitted illumination, diaphragm controls, mechanical stage and coarse and fine focusing. For camera use, define the camera port and supplied adaptor rather than accepting a photograph of a trinocular head as the specification.
Approve a sample using prepared biological slides and a stage micrometer. Record the expected sharpness across the field, focus retained when changing objectives, and stage movement without drift. Confirm which objectives, eyepieces, slide holders and replacement illumination parts are included.
For mains-powered models sold in Great Britain, confirm with the relevant authority which electrical safety evidence, CE or UKCA marking, declaration of conformity and UK importer identification are required. Also confirm whether electromagnetic compatibility, restricted substances and waste electrical equipment obligations apply. Arrange testing and certification around the exact microscope and power supply being ordered.
Worked duty example
Illustrative example, not a quote: Illustrative order: 150 laboratory biological compound microscopes 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
Optics: view the same prepared slide at every supplied magnification; check central and edge sharpness, parfocality, and absence of dust or fungus in the optical path.
Mechanics: check coarse and fine focus without slipping, smooth stage travel, secure slide holding and positive nosepiece positioning.
Illumination: check brightness adjustment, even illumination and the supplied power adaptor against the approved sample and supporting documents.
Documents and packing: check model identification, conformity documents and importer details. Electrical equipment must have easily understandable English instructions. Check that foam holds the instrument securely and protects the objectives during transport.

What goes wrong
A stated magnification does not establish image quality. Objectives may lose focus when changed, field edges may appear soft, and focusing mechanisms may creep under load. Damp storage can leave fungus inside the optics. Loose packing can shift alignment even when the outer carton looks intact.
Keep the approved sample and slide images as inspection references. Agree the checks with the supplier before production and repeat optical and mechanical checks on arrival. Specify dry storage and fixed packing, and use the quality inspection guide to prepare the inspection brief.

Frequently asked questions
What is the UK import duty on biological microscopes from China?
The relevant biological compound microscope and parts entries under heading 9011 carry 0% duty for goods from China. The supplied tariff record shows no anti-dumping or countervailing duty.
Does a trinocular head determine the commodity code?
Confirm the complete instrument's functions and supplied configuration, including its photographic equipment. Do not select the code from the head description alone.
What paperwork should I request for a mains-powered microscope?
Request electrical safety evidence for the exact model and power supply, a declaration of conformity, CE or UKCA marking, UK importer identification and English instructions for the Great Britain market.
How do I check microscope quality on arrival?
Use a prepared slide and stage micrometer. Check sharpness across the field, focus when changing objectives, stage and focusing movement, illumination, cleanliness and transport damage.
