Sourcing ultrasound coupling gels from China

UK duty on ultrasound coupling gels

Heading 3006 includes medical gel preparations used to couple the body and medical instruments. Ultrasound coupling gels fall within 3006 70 00 00. The table shows pack formats within that same tariff line, rather than separate commodity codes.

Read from the UK Trade Tariff on 30 September 2026, ultrasound coupling gels from China carried 0% duty. The supplied tariff record lists no anti-dumping or countervailing duty, suspension or attached import control for this line. Medical device requirements still apply independently of the tariff.

Confirm the commodity code using the formulation, intended medical use and product documentation. For other products within this heading, see the first aid kits and medical sundries guide.

Specify the gel and its dispensing pack

Specify the intended examination, sterile or non-sterile status, formulation, viscosity, colour, fragrance, pack contents and dispensing method. Agree compatibility checks with the intended ultrasound equipment and an approved sample. Ask for batch microbiological results, storage instructions and an agreed remaining shelf life at delivery.

For sale in Great Britain, check the medical device classification, applicable UKCA or CE marking, declaration of conformity and any relevant certificate. The Chinese manufacturer needs a UK Responsible Person; confirm the device registration requirements and timing with MHRA before placing it on that market.

England's ultrasound gel guidance distinguishes single-use sachets or tubes from pre-filled disposable bottles. Single-use packs are discarded after an examination. Choose the pack format with the clinical buyer before approving artwork or production.

Worked duty example

Illustrative example, not a quote: Illustrative order: 10,000 single-use non-sterile ultrasound gel sachets under 3006 70 00 00, invoiced at £4,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £5,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,500, so it is £1,100. 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

Gel: compare appearance, consistency, spreading and dispensing with the approved sample; investigate separation, clumps or an unexpected smell.

Packaging: check sachet and tube seals, bottle closures, leaks and transport damage; for sterile products, review sterilisation validation and sterile packaging records.

Traceability: match batch identification, expiry dates and storage instructions across packs, cartons and batch documents; check the agreed remaining shelf life.

Documents: match the manufacturer and exact product to the conformity documents, marking and registration; use testing and certification support where specialist review is needed.

What goes wrong

A clear gel and an intact bottle do not establish sterility. Standard ultrasound gel is not produced as a sterile product, although sterile versions are available. Check that the ordered sterile status matches the label, batch evidence and packaging.

Other problems include leaking seals, gel that separates or dispenses poorly, short remaining shelf life and documents covering a different formulation. A dispensing bottle can also be bought for an unsuitable refill workflow: England's guidance describes pre-filled disposable bottles as non-refillable. Agree the user's dispensing method before ordering.
