A proposed UK import duty on a widely used white pigment has consequences beyond the chemical company seeking protection. On 7 October, the Trade Remedies Authority published an initial recommendation to impose anti-dumping measures on rutile titanium dioxide imported from China. The chemical is used in paint, plastics, coatings and paper. The recommendation is open for comments until 26 October, after which a final recommendation must be considered by the responsible minister. Importers should therefore treat the rates as a live regulatory proposal, not an additional charge already in force.
The proposed rates are specific and substantial
The authority recommends a mixed measure for five years. For cooperating exporters, the proposed ad valorem rate is 48.29%, with a minimum of £0.665 per kilogram; for other exporters, the proposal is 63.66%, with a minimum of £0.876 per kilogram. The applicable calculation depends on which method generates more duty. The TRA says Chinese import volumes in May 2026 exceeded the May 2025 volume by more than 299%, and that dumping threatens injury to UK producers. The investigation covers specified rutile products and customs codes. Other titanium dioxide forms should not automatically be assumed to fall within scope.
Protection for one manufacturer becomes a cost question for customers
The proposed measure is intended to protect UK production capacity and jobs. Downstream manufacturers, however, use the pigment as an input, so their costs depend on sourcing arrangements, available substitutes and the extent to which exporters change prices. A duty can encourage domestic supply without guaranteeing that local producers can meet every specification or delivery schedule. Paint and plastics manufacturers should check whether contracts allow tariff-related price adjustments, whether stocks were imported before any implementation date and whether a supplier's exact product meets the legal description. These are commercial questions distinct from the TRA's determination about dumping.
The next decision follows consultation
Affected businesses can examine the public case file AD0086 and submit comments before the 26 October deadline. The TRA will then make its final recommendation to the government. Importers should follow the final legal notice and any implementation date rather than relying on the initial press release alone. The economic-interest assessment also matters because the effects extend from domestic pigment production to many downstream customers. The current stage is an initial finding and proposed remedy, not a final tariff schedule.
