Sourcing glass wool pipe insulation from China
The relevant other-glass-wool line carries 6% UK duty from China, with no additional trade remedy recorded. Confirm with the relevant authority whether a designated standard applies to the building insulation and what declaration of performance and UKCA or CE marking are needed. Check pipe fit and evidence for the supplied facing. Cambridge China Bridge sources glass wool pipe insulation.
Duty on glass wool pipe insulation
Read from the UK Trade Tariff on 30 September 2026, heading 7019 covers glass fibres, including glass wool and its articles. The relevant other-glass-wool line, 7019 80 90 90, carries 6% duty for goods from China. No anti-dumping duty, countervailing duty or suspension is recorded for this line. The table shows product variants sharing this tariff line, subject to confirmation of the finished construction.
The tariff attaches import and export waste controls to this line. For material imported from China into England as waste under notification controls, the exporter must apply to the competent authority in the country of dispatch for consent and follow its procedures. Before buying offcuts or recovered insulation, ask your customs broker to confirm the waste classification and applicable notification and consent requirements.
Confirm the commodity code using the material, shape, facing and intended use. The wider glass fibre and glass wool guide covers other forms under this heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Unfaced glass wool pipe insulation sections | 7019 80 90 90 | 6% | None |
Specify the bore, split and facing
Specify the actual pipe outside diameter, insulation bore, wall thickness, section length and dimensional tolerances. Describe the longitudinal split, closure flap, facing material and matching pieces for bends. Approve a sample fitted around the intended pipe, checking that the split closes without crushing the insulation.
State whether the application is hot pipework or cold pipework. Request thermal conductivity evidence at the intended operating conditions, temperature suitability for the wool, binder and facing, and installation instructions for joints and closures. For cold pipework, agree how the facing and joints will form a continuous vapour barrier.
For building insulation, confirm with the relevant authority whether a designated standard applies and whether a declaration of performance and UKCA or CE marking are required. Check that the declaration and reaction to fire evidence identify the supplied product and facing. Ask the supplier to confirm the standard applicable to pipe sections and their intended use. Arrange testing and certification checks before approving production.
Worked duty example
Illustrative example, not a quote: Illustrative trial stock order of foil-faced glass wool pipe sections in assorted bores under 7019 80 90 90, invoiced at £9,000 free on board, with £2,400 of freight and insurance to the UK. The customs value is £11,400. Duty at 6% is £684. Import VAT at 20% is charged on the customs value plus duty, £12,084, so it is £2,416.80. Import taxes total £3,100.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £684 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Fit: measure bore, wall thickness and length against the purchase specification; fit sampled sections around the intended pipe and check split closure and end alignment.
Facing: check foil adhesion, tears, closure flap position and adhesive release liners; assemble a sample joint using the supplied instructions.
Evidence: match product identifiers and batch labels to the declaration of performance, thermal reports and reaction to fire evidence, including the supplied facing.
Packing: open sampled packs on arrival to check for damp wool, crushed sections and distorted bores; record defects before installation. Use the quality inspection guide to prepare the inspection brief.

What goes wrong
A bore specified from the pipe's nominal size can leave a gap or force installers to crush the insulation. Uneven wall thickness and damaged ends leave poorly fitting joints. Torn foil, lifting flaps and badly sealed closures interrupt the intended vapour barrier on cold pipework.
Wet or crushed packs can leave insulation misshapen and below its specified thickness. A report for an unfaced slab does not establish the performance of the supplied faced pipe section. Compare samples and documents with the exact ordered construction, and agree how defective stock will be isolated and replaced.

Does glass wool pipe insulation need UKCA or CE marking?
Check the applicable standard and evidence for the exact pipe section and facing.
What dimensions should I give the Chinese factory?
Give the actual pipe outside diameter, insulation bore, wall thickness, section length and tolerances. Include split, closure flap and bend details, then approve a fitted sample.
What should I check when glass wool pipe insulation arrives?
Check bore fit, wall thickness, end alignment, foil adhesion and closure flaps. Open sampled packs for damp or crushed wool and match batch labels to the ordered product and performance documents.
