On November 21th, 2025, the publication of SECEX Ordinance nº 91/2025 initiated an anti-dumping investigation on Brazilian imports of purified phosphoric acid with a concentration greater than 55% and less than 105% H3PO4, originating from China, Morocco, and Mexico. The product is usually classified under subheading 2809.20.11 of the Mercosur Common Nomenclature (NCM).

The opening of the investigation was motivated by a petition filed on July 30th, 2025, by ICL Aditivos e Ingredientes Ltda. After a preliminary analysis, the Foreign Trade Secretariat (SECEX), through the Department of Trade Remedies (DECOM), found sufficient evidence of dumping, injury to the domestic industry, and a causal link between them.

The main information regarding the investigation is summarized below:

  • Petitioner: ICL Aditivos e Ingredientes Ltda.
  • Origin: China, Morocco, and Mexico.

  • Period of investigation:

Dumping: April 2024 to March 2025; and

Injury: April 2020 to March 2025.

  • Product under investigation:

Classification: 2809.20.11 of the NCM; and

Description: food grade purified phosphoric acid with a concentration greater than 55% and less than 105% H3PO4.

  • Dumping margins for initiation purposes:

China:

Absolute dumping margin: US$ 818,60/t; and

Relative dumping margin: 80%.

Morocco:

Absolute dumping margin: US$ 710,98/t; and

Relative dumping margin: 65%.

Mexico:

Absolute dumping margin: US$ 824,61/t; and

Relative dumping margin: 70%.

The participation of interested parties — including domestic producers, importers, exporters and governments of the countries under investigation — must necessarily be carried out through petitions in the Electronic Information System (SEI) of the Ministry of Development, Industry, Trade and Services (MDIC).

Questionnaires will be sent to the identified interested parties, who will have 30 days from the date of the notification to send their responses. Parties not initially identified at the beginning of the proceeding, but whoever considers themselves interested, may request to be admitted to the case by December 15th, 2025.

During the investigation, provisional antidumping measures may be applied if sufficient evidence of unfair trade practices is found and if it is understood that such measures are necessary to prevent injury to the domestic industry during the investigation.

The investigation must be completed within 10 months, extendable for up to 8 additional months. If the initial claims are confirmed, definitive antidumping measures may be applied for a period of up to 5 years.
