Sourcing plastic cistern lids from China
The supplied heading has a single duty rate of 6% for goods from China. Plastic toilet cistern lids need a confirmed commodity code and, for consumer use in Great Britain, must be safe. Match the underside locating rim and button opening to the actual cistern. Cambridge China Bridge sources plastic toilet cistern lids.
UK duty on plastic toilet cistern lids
Read from the UK Trade Tariff on 1 October 2026, heading 3922 covers plastic sanitary ware, including flushing cisterns. For a separate plastic cistern lid, treat 3922 90 00 00, described as Other, as a candidate classification to confirm. The supplied facts contain only one relevant line; the table therefore shows that line.
The supplied tariff lines all carry 6% duty for goods from China. The snapshot lists no anti-dumping or countervailing duty, suspensions or attached import controls. This guide covers the lid itself; see plastic toilet cisterns for the complete product.
Send your customs broker the material specification, photographs, underside drawing and details of any supplied button assembly. Confirm the classification using finding your commodity code before ordering.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other plastic sanitary ware: candidate line for toilet cistern lids | 3922 90 00 00 | 6% | None |
Specify the lid against the actual cistern
Provide a reference cistern and an approved lid sample. Specify overall shape, underside locating rim, seating depth, corner radii, button-hole position and clearance above the flushing mechanism. State whether the lid is supplied alone or with a button assembly, and agree the plastic material, wall thickness, reinforcing ribs, colour and gloss.
For consumer use in Great Britain, general product safety rules require safe products and include UK-based importers among producers. Traceability should identify the producer's name and address and the product reference or applicable batch on the product or packaging, where reasonable. Keep those details connected to your sample and inspection records.
Worked duty example
Illustrative example, not a quote: 300 plastic toilet cistern lids, illustrative only under 3922 90 00 00, invoiced at £6,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £7,500. Duty at 6% is £450. Import VAT at 20% is charged on the customs value plus duty, £7,950, so it is £1,590. Import taxes total £2,040; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £450 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Fit: seat sampled production lids on the intended cistern; check rocking, locating-rim engagement and clearance around the flush mechanism.
Button opening: fit the intended button assembly and operate it with the lid seated; check rubbing, sticking and accidental pressure on the mechanism.
Moulding and finish: check underside ribs, cracks, sharp flash, sink marks and warping; compare colour and gloss with the approved sample.
Packing and identity: check protective separation, edge protection and model labels; match producer and product or batch details to the shipment records. Use quality inspection to document findings.

What goes wrong
A lid can match the visible outline yet fail because the underside rim or corner shape is different. A misplaced button opening can make the button bind, while insufficient internal clearance can press on the flushing mechanism. Approve fit on the actual cistern rather than from a photograph.
Uneven cooling can leave the lid warped, and unsupported stacking can damage corners or mark the visible surface. Agree packing using production samples and check lids after unpacking. Keep different cistern models separately identified to prevent warehouse picking errors.

Frequently asked questions
What is the UK import duty on plastic toilet cistern lids from China?
The supplied tariff snapshot shows 6% on 3922 90 00 00, the candidate Other line for plastic sanitary ware. Confirm classification for your lid. No trade remedy, suspension or attached import control is listed.
Will a universal plastic lid fit my toilet cistern?
Check it on the actual cistern. Overall dimensions alone do not establish fit: the underside rim, corners, seating depth and flush-button clearance also matter.
What safety information should I arrange for GB sales?
For consumer lids, arrange product safety checks and traceability. Where reasonable, the product or packaging should identify the producer's name and address and the product reference or applicable batch.
What should I send a Chinese cistern-lid factory?
Send a reference cistern or verified drawings, an approved lid sample, material and finish requirements, button details and packing instructions. Require approval before changing the material or mould.
