Sourcing NPG diglycidyl ether from China

Duty and classification

Read from the UK Trade Tariff on 5 October 2026, heading 2910 covers epoxides and related compounds, including epoxyethers. For neopentyl glycol diglycidyl ether, consider the residual line 2910 90 00 90, subject to confirmation of chemical identity and composition. The supplied data contains no dedicated named line for this product.

That candidate line carries 0% duty for goods from China, with no anti-dumping or countervailing measure and no suspension listed. The tariff attaches an export control for waste. Environment Agency guidance says waste shipment controls apply only to waste. If the consignment is recovered material or waste, ask your customs broker to confirm the applicable requirements before shipment.

Give your broker the chemical identity, composition, safety data sheet and intended use to confirm the commodity code. Only the residual line is shown here because the other named substances are different products. For wider heading context, see butyl glycidyl ether.

Specify the reactive diluent and registration coverage

State neopentyl glycol diglycidyl ether explicitly in the purchase specification. Agree epoxy equivalent weight, viscosity, colour, water and hydrolysable chlorine, with test methods and acceptance criteria. Ask for composition details and a batch certificate of analysis. Qualify the sample in your own resin and curing system rather than approving it on appearance alone.

For Great Britain, UK REACH registration responsibilities arise when annual imports of a substance reach one tonne. Confirm your registration route or the supplier's only representative coverage before ordering. Importers must meet chemical classification, labelling and packaging duties. A safety data sheet is required when a hazardous chemical is supplied for workplace use.

Worked duty example

Illustrative example, not a quote: Illustrative small-business order of neopentyl glycol diglycidyl ether in drums under 2910 90 00 90, invoiced at £24,000 free on board, with £3,500 of freight and insurance to the UK. The customs value is £27,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £27,500, so it is £5,500. 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

Identity: match the chemical name, composition and batch reference across the order, certificate of analysis, safety data sheet and drum labels.

Reactivity: test epoxy equivalent weight and compare the result with the approved sample using the agreed method.

Condition: check viscosity, colour, water and hydrolysable chlorine against the specification; record sampling conditions and retain a sealed sample.

Packaging: inspect seals, closures, corrosion and leakage before acceptance; reconcile drum labels and batch records. Arrange testing through testing and certification.

What goes wrong

A supplier may offer a different glycidyl ether or a blend under a similar reactive-diluent description. Differences in epoxy equivalent weight, viscosity or colour can make the delivered lot unsuitable for the qualified formulation. Require approval of composition changes and compare arrival samples with the retained approved sample.

Generic certificates and mismatched batch references make a disputed delivery difficult to assess. Agree sampling, test methods and rejection criteria before production. Check the documents before loading and inspect the drums on arrival; use the quality inspection guide to organise the checks.
