Sourcing inverted microscopes from China
Inverted optical microscopes from China carry 0% UK duty across the relevant heading 9011 lines. For mains-powered laboratory models, confirm the applicable electrical safety requirements with the relevant authority before sale in Great Britain. Specify vessel clearance, objective working distance and imaging compatibility. Cambridge China Bridge sources inverted optical microscopes.
UK duty on inverted optical microscopes
Read from the UK Trade Tariff on 1 October 2026, heading 9011 covers compound optical microscopes, including instruments for photomicrography, cinephotomicrography or microprojection. All listed lines carry 0% duty for goods from China, with no anti-dumping or countervailing duty and no listed suspensions.
The tariff attaches a DCMS Export Licence entry to each line. Official guidance says there are no licensing requirements for importing objects of cultural interest into Great Britain. Ask your customs broker to confirm the attached entry for your shipment, especially for used instruments, and check any origin-country export requirements.
Confirm the commodity code from the instrument's function and supplied equipment. The specialised semiconductor line applies to photomicrographic instruments with dedicated wafer or reticle handling equipment, rather than ordinary cell-culture microscopes. See the wider microscope guide for the heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other microscopes, including inverted laboratory models | 9011 80 00 00 | 0% | None |
| Other microscopes for photomicrography, including suitable inverted models | 9011 20 90 00 | 0% | None |
| Microscope parts and accessories | 9011 90 00 00 | 0% | None |
| Photomicrographic microscopes with dedicated wafer or reticle handling equipment | 9011 20 10 00 | 0% | None |
Specify vessels, objectives and contrast
Specify whether the microscope will view cells through culture vessels or examine opaque specimens. State transmitted or reflected illumination, vessel types, bottom material and thickness, objective working distance, optical correction system and stage inserts. Send the factory the actual vessels or representative samples so it can demonstrate clearance and focus through the base.
For phase contrast, match each objective to its condenser annulus and require an alignment demonstration. Define the camera port, adaptor, sensor coverage and whether observation and camera imaging can operate together. Agree which objectives, filters, holders and cables are included.
For mains-powered laboratory 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, and consult the wider guide. Electrical equipment within scope must have clear, legible instructions in easily understandable English.
Worked duty example
Illustrative example, not a quote: Illustrative shipment of inverted laboratory 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
Vessel fit: use the agreed dishes, flasks and stage inserts; check condenser clearance, access to the specimen and focus through the vessel base.
Optics: check centre and edge sharpness, parfocality and phase contrast alignment with representative specimens; compare the camera image with the eyepiece view.
Mechanics: check smooth stage travel, secure vessel holders, positive objective positioning and focus that holds without drift.
Electrics and packing: check illumination, dimming, the supplied power supply, marking and documents; inspect for moisture and movement inside the packing. Use the inspection guide to record results.

What goes wrong
A microscope may focus on a demonstration slide but fail through the buyer's culture vessel. Unsuitable working distance, mismatched vessel-bottom thickness or a condenser that obstructs a flask can make the intended workflow impractical. Phase contrast also fails when objectives and annuli are mismatched or poorly centred.
Camera adaptors can crop the image or prevent the camera and eyepieces from focusing together. Loose stage inserts, focus drift, damp optics and transit movement cause further failures. Approve a sample using your vessels and camera, then repeat those checks on arrival.

Frequently asked questions
What is the UK import duty on inverted microscopes from China?
The relevant heading 9011 lines carry 0% duty for goods from China in the supplied tariff reading, with no anti-dumping or countervailing duty.
Which commodity code covers an inverted microscope?
Other microscopes are listed under 9011 80 00 00; other photomicrographic microscopes under 9011 20 90 00. Confirm the function and supplied equipment with your customs broker.
Will an inverted microscope work with my culture flasks?
Have the factory demonstrate your actual flask, bottom material and thickness. Check objective working distance, condenser clearance, holder fit and image quality through the base.
What documents should a mains-powered microscope have?
For a laboratory model sold in Great Britain, check electrical safety evidence, CE or UKCA marking, a declaration of conformity, UK importer identification and clear English instructions.
