European Union Imposes Definitive Duties On Chinese PBTC Imports

EU PBTC Anti-Dumping Duties Are Published

The European Union has published definitive PBTC anti-dumping duties on imports originating in China. Commission Implementing Regulation (EU) 2026/2088 was published on 21 September 2026 and entered into force on 22 September.

The covered product is 2-phosphonobutane-1,2,4-tricarboxylic acid and its sodium salt, tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate, known as PBTC, in solid form or aqueous solution. The regulation identifies CN code 2931 49 80, TARIC code 2931 49 80 60, CAS numbers 37971-36-1 and 66669-53-2, and specified CUS and European Community identifiers.

Duty Rates And Customs Conditions

The definitive duty is calculated on the net free-at-Union-frontier price before duty. Shandong Taihe Technologies Co., Ltd receives a rate of 156.7%, Jiyuan Qingyuan Water Treatment Co., Ltd 183.8%, and Nantong Uniphos Chemicals Co., Ltd 192.2%. Other cooperating companies listed in the annex receive 173.8%, while all other Chinese imports receive 192.2%.

An individual rate applies only where customs receives a valid commercial invoice containing the prescribed signed declaration and the producer's TARIC additional code. Without that invoice, the 192.2% all-other rate applies. Customs may request shipping or other evidence even when the declaration is present.

Amounts secured under provisional Regulation (EU) 2026/1045 are to be collected definitively. Any secured amount exceeding the definitive rate must be released. The regulation also provides a route for qualifying new exporters to request the 173.8% rate for cooperating companies not sampled.

A trader may issue the commercial invoice if the prescribed declaration identifies the qualifying manufacturer and TARIC additional code. Goods made by another legal entity cannot use a named producer’s rate merely because the entities are related.

The Commission concluded that the conditions for retroactive collection on registered pre-provisional imports were not met. That conclusion is separate from definitive collection of secured provisional amounts.
