Sourcing rubber sink plugs from China

Rubber sink plug duty and classification

Read from the UK Trade Tariff on 17 October 2026, heading 4016 covers other articles of vulcanised rubber other than hard rubber. For ordinary solid rubber sink plugs, consider 4016 99 97 90, subject to confirmation of the finished article. The table shows product forms within this candidate line; these are not separate tariff classifications.

The candidate line carries 2% duty for goods from China, with no anti-dumping or countervailing duty or attached import controls shown. Its 0.00 % suspension is restricted to disposable plastic or rubber boot covers or overshoes and does not cover sink plugs.

Send the broker the rubber composition, drawings and details of any chain, metal insert or bonded component before confirming the commodity code. For the wider product family, see bathroom accessories.

Specify the drain fit and rubber compound

Specify the drain opening and seating shape, plug diameter, taper, depth, sealing rim and pull-tab design. Provide a representative drain fitting and retain an approved sample. State whether the plug seals inside the opening or lies across its rim; a nominal diameter alone does not establish fit.

Agree the rubber composition, hardness, colour, finish and intended water and cleaning conditions. Specify whether a chain is included, its attachment and packing arrangement. Ask for material-specific chemical evidence rather than accepting a report for a different compound.

For plugs intended or likely to be used by consumers in Great Britain, the General Product Safety Regulations 2005 apply. Confirm the applicable safety obligations with the relevant authority. Agree supporting safety information for the intended use and consider detached pull tabs, sharp chain fittings and foreseeable handling.

Worked duty example

Illustrative example, not a quote: Illustrative order: 3,000 solid rubber sink plugs without chains under 4016 99 97 90, invoiced at £2,500 free on board, with £350 of freight and insurance to the UK. The customs value is £2,850. Duty at 2% is £57. Import VAT at 20% is charged on the customs value plus duty, £2,907, so it is £581.40. Import taxes total £638.40; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £57 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Fit: compare dimensions and profile with the approved drawing; trial-fit plugs in representative drain fittings and check insertion and removal.

Seal: fill the representative sink and check leakage against the agreed acceptance criteria; repeat after exposure to the intended water and cleaning conditions.

Moulding: inspect the sealing surface for flash, cracks, voids and distortion; compare flexibility, colour and surface transfer with the approved sample.

Attachments and packing: check pull-tab strength, chain attachment and sharp edges; verify product identification and inspect for packing deformation. Use our quality inspection guide to plan checks.

What goes wrong

A plug can match the advertised diameter yet leak because its taper or sealing rim differs from the drain. Moulding flash interrupts the seal, a stiff compound prevents seating, and packing pressure distorts the rim. A pull tab or chain attachment may also fail during removal.

Approve samples in the actual drain fitting before production. Record the agreed leakage, removal and material checks in the purchase specification. Keep arrival results linked to the batch so that a changed compound or mould can be investigated.
