Sourcing self-cleaning glass units from China
Self-cleaning insulating glass units from China carry 0% UK duty across the relevant heading 7008 lines, with no anti-dumping or countervailing duty shown. For building use, the units need a declaration of performance and construction product marking. Check coating orientation and edge seals. Cambridge China Bridge sources self-cleaning insulating glass units.
Duty on self-cleaning insulating glass units
Heading 7008 covers multiple-walled insulating units of glass. This guide concerns sealed units incorporating self-cleaning glass, rather than complete framed windows. See the double-glazed units guide for the wider heading.
Read from the UK Trade Tariff on 2 October 2026, all listed lines carried 0% duty for goods from China. The supplied tariff record shows no anti-dumping or countervailing duties, suspensions or attached import controls. Import VAT is separate from customs duty.
The self-cleaning description alone does not settle classification. Establish whether the glass is body-tinted, opacified, flashed or has an absorbent or reflecting layer, then check the sealed unit construction. Confirm the commodity code using the actual glass specification.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Self-cleaning insulating units with body-tinted glass | 7008 00 20 00 | 0% | None |
| Other self-cleaning insulating units with two sealed glass panels | 7008 00 81 00 | 0% | None |
| Other self-cleaning insulating units, including triple glazing | 7008 00 89 00 | 0% | None |
Specify the self-cleaning surface and sealed unit
Specify the coating manufacturer and product, the intended outward-facing surface, and the glass make-up pane by pane. Record dimensions, thickness, safety glass, spacer, gas fill, edge seal system and thermal performance. Ask the supplier to explain required daylight and rain exposure, cleaning instructions, and compatibility with glazing sealants. Agree a sample and an acceptance method for the self-cleaning claim.
For building use, confirm with the relevant authority which construction product rules described in our wider guide apply to the insulating glass units, including any declaration of performance and marking requirements. Ask for documents covering the ordered make-up, initial type testing and factory production control. CE marking continues to be recognised for construction products supplied in Great Britain. A self-cleaning brochure should accompany, rather than replace, the unit's performance documents.
Worked duty example
Illustrative example, not a quote: 1,200 small self-cleaning insulating glass units, assuming classification in this line; illustrative only under 7008 00 81 00, invoiced at £36,000 free on board, with £6,000 of freight and insurance to the UK. The customs value is £42,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £42,000, so it is £8,400. 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.
Inspection checklist
Coating: match the supplied glass to the approved product, confirm the outward-facing surface against the drawing, and inspect for scratches, residues and uneven appearance using the agreed viewing conditions.
Dimensions: measure sampled units against the cutting list, including overall thickness, pane make-up and spacer position. Match unit labels to their intended openings.
Edge seals: inspect corners, seal continuity and spacer alignment. Match the sealants and spacer to the supplied durability test evidence, and check for misting between panes on arrival.
Packing: check upright support, separators, edge protection and crate restraint before loading. On arrival, photograph damaged crates and inspect the glass before signing off the delivery. Use the inspection guide to set the inspection brief.

What goes wrong
An unclear drawing can leave the self-cleaning surface facing the cavity or room. Substituted glass, coating damage and unsuitable cleaning materials can also undermine the ordered finish. Ask for coating identification, handling instructions and a compatibility statement for the proposed glazing materials before approving production.
Self-cleaning glass does not resolve weak edge seals, incorrect sizes or transit breakage. Separate coating complaints from condensation between panes, and agree how the supplier will identify affected units and handle replacements. Keep the approved sample, cutting list, inspection photographs and batch documents together.

Frequently asked questions
What is the UK import duty on self-cleaning insulating glass units from China?
Read from the UK Trade Tariff on 2 October 2026, all listed heading 7008 lines carried 0% duty from China, with no anti-dumping or countervailing duty shown. Import VAT is separate.
Does a self-cleaning coating decide the commodity code?
The name alone does not settle it. Check the glass treatment, whether it has an absorbent or reflecting layer, and the sealed unit construction against the tariff descriptions.
What documents should I request for building use?
Request the declaration of performance, construction product marking details and test evidence for the ordered unit. Ask separately for coating identification and cleaning instructions.
How do I check the self-cleaning surface is facing outside?
Require the factory drawing and unit labels to identify the coated surface. Check sampled units against that drawing using the coating supplier's identification method before shipment and installation.
