Sourcing borosilicate glass oven dishes from China
Chinese borosilicate glass oven dishes carry 10% UK duty on the relevant kitchenware lines, with no variation across the listed rates. Food-contact materials must be safe and suitable for their intended use. Confirm glass composition, thermal performance and any lid restrictions before ordering. Cambridge China Bridge sources borosilicate glass oven dishes.
UK duty and glass classification
Read from the UK Trade Tariff on 29 September 2026, heading 7013 covers table, kitchen and other household glassware. Borosilicate oven dishes should be assessed against 7013 42 00 00, the low-expansion kitchenware line. The other table rows are classification alternatives if that line does not apply, rather than interchangeable codes for borosilicate dishes. All listed lines carry 10% ordinary duty for goods from China; the supplied tariff record lists no anti-dumping duty, countervailing duty or suspension on them.
The tariff attaches cat and dog fur import and export controls: products containing that fur are banned. Specify dishes and accessories without such fur. It also lists a cultural-object export licence control; ask your customs broker to confirm the requirement if re-exporting. That entry concerns export rather than the purchase of new oven dishes from China.
Obtain the glass composition and linear expansion report before confirming the commodity code. Do not classify solely from the supplier's borosilicate description. For the wider heading, see glass candle jars and lids, whose use and classification differ from oven dishes.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Low-expansion glass kitchenware, including qualifying borosilicate oven dishes | 7013 42 00 00 | 10% | None |
| Other toughened glass kitchenware, if the low-expansion line does not apply | 7013 49 10 00 | 10% | None |
| Other hand-gathered glass kitchenware, outside the low-expansion line | 7013 49 91 00 | 10% | None |
| Other mechanically gathered glass kitchenware, outside the low-expansion line | 7013 49 99 00 | 10% | None |
Specify the glass, oven use and lid separately
Write the glass composition, expansion characteristics, usable capacity, external dimensions including handles, wall and base thickness, rim finish and base flatness into the order. Keep an approved production sample. Agree oven-use conditions and a laboratory thermal-shock test programme, including heating and cooling conditions, before approving any oven-safe claim.
Food-contact materials must be safe and suitable for their intended use. Ask for reports covering the actual dish, decoration and food-contact accessories under the proposed cooking conditions. Treat a plastic lid, silicone seal and glass lid as separate components: specify their permitted uses and removal instructions. Arrange testing and certification around the finished product rather than a generic glass sample.
Worked duty example
Illustrative example, not a quote: Illustrative order of 500 borosilicate glass oven dishes; illustrative whole-pound values under 7013 42 00 00, invoiced at £2,400 free on board, with £500 of freight and insurance to the UK. The customs value is £2,900. Duty at 10% is £290. Import VAT at 20% is charged on the customs value plus duty, £3,190, so it is £638. Import taxes total £928; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £290 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Glass and dimensions: compare sampled dishes with the approved sample; measure capacity, handles, rim, wall and base thickness, and check that the base sits flat.
Damage and finish: check rims and handles for chips, cracks and sharp edges; inspect the base and walls for inclusions, scratches and uneven moulding.
Performance and paperwork: match material and food-contact reports to the ordered design; review thermal test results and ensure dish and lid instructions reflect their separately agreed uses.
Packing and arrival: open packed cartons to check dividers, cushioning and separation between nested dishes; inspect arrivals for broken glass, chipped rims and abrasion before releasing stock.

What goes wrong
A supplier may substitute a different glass composition while retaining the borosilicate description. A report for plain glass may omit printed decoration or the supplied lid. Compare the production material and finished design with the tested samples, and agree that substitutions need your approval.
Tightly nested dishes can rub or chip in transit, and poorly supported handles can break. A lid that fits the reference sample may distort or fit badly on production dishes. Check packed samples and lid fit across the batch; keep oven-use claims within the tested conditions rather than relying on the material name.

Frequently asked questions
What is the UK import duty on borosilicate oven dishes from China?
The supplied tariff record shows 10% on 7013 42 00 00 and the listed alternative kitchenware lines, with no anti-dumping duty, countervailing duty or suspension.
Which commodity code covers borosilicate glass oven dishes?
Assess 7013 42 00 00 using the glass's linear expansion evidence. The supplier's borosilicate description alone does not establish the classification.
Does borosilicate glass mean the lid is oven-safe?
Assess the lid separately. Ask for its material, tested use conditions and instructions; do not extend the dish's oven-use claim to a plastic lid or seal.
What should I check when glass oven dishes arrive?
Check chipped rims, cracked handles, flat bases, lid fit and damage between nested dishes. Compare dimensions and packing with the approved sample and retain the batch's test records.
