Sourcing Rubber Pipette Bulbs from China

Rubber pipette bulbs: 0% duty

Heading 4014 covers hygienic or pharmaceutical articles of vulcanised rubber other than hard rubber, with or without hard rubber fittings. This guide covers pipette bulbs classified within that description. The table shows product variants sharing the same tariff line, rather than separate commodity lines. For the wider product family, see rubber bulb syringes.

Read from the UK Trade Tariff on 30 September 2026, code 4014 90 00 00 carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls for this line.

Confirm the commodity code using the material declaration, drawings and intended use. Do not select the heading from the word rubber alone. Give your customs broker details of any valves, fittings and accompanying pipettes.

Specify pipette fit, rubber and valve behaviour

Specify the rubber type, neck opening and tolerances, bulb shape, wall thickness, squeeze resistance and recovery after release. Identify the actual pipettes it must fit. For valved bulbs, agree how air release, suction and dispensing operate, with an approved sample and a repeatable acceptance test.

Agree compatibility with the liquids, vapours and cleaning methods used by your buyer. Ask for compound information and supporting tests. REACH restrictions can limit, ban or condition the placing on the market or use of substances; have the compound assessed against applicable restrictions rather than accepting an unsupported compliance statement.

Suppliers must supply safe work equipment. Record the intended use and request operating and cleaning instructions. Not every item used in a hospital is a medical device. Resolve medical-device status before ordering; if the bulb is a medical device, a manufacturer based in China must appoint a UK responsible person.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2,000 valved rubber pipette bulbs; illustrative FOB value and freight under 4014 90 00 00, invoiced at £5,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £7,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £7,000, so it is £1,400. 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. This assumes the goods are standard-rated for VAT. Contraceptive products sold other than on prescription take the reduced rate of VAT under HMRC's VAT Notice 701/57, so check the rate for your product.

Inspection checklist

Fit: check sampled bulbs on the buyer's actual pipettes for secure attachment, air leakage and damage during fitting.

Suction and valves: draw and hold water, operate each valve and check controlled release against the approved sample.

Rubber condition: check neck tears, moulding flash, tackiness, cracks and incomplete recovery after repeated squeezing.

Packing and identity: check cleanliness, deformation from packing, product references and batch identification against the order. Agree the checks with your inspection provider.

What goes wrong

A neck that looks suitable can leak on the buyer's pipette or grip it so tightly that fitting becomes difficult. Poor valve seating causes loss of suction or uncontrolled dispensing. A changed compound can make the bulb harder to squeeze, slower to recover or prone to swelling during use.

Keep an approved sample, record the compound and fitting dimensions, and require approval before material or valve changes. Test samples after the agreed cleaning process and unpack arrival samples before releasing the batch for use.
