On September 18th, 2025, the publication of SECEX Ordinance nº 70/2025, initiated an anti-dumping investigation on Brazilian imports of crude or glacial acrylic acid originating from China. The product is usually classified under subheading 2916.11.10 of the Mercosur Common Nomenclature (NCM).

The opening of the investigation was motivated by a petition filed on April 30th, 2025, by BASF S/A. 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: BASF S/A.
  • Origin: China.

For the purposes of initiating the investigation, DECOM considered that market economy conditions do not prevail in the Chinese acrylic acid production sector.

  • Period of investigation:

Dumping: January 2024 to December 2024; and

Injury: January 2020 to December 2024.

  • Product under investigation:

Classification: usually classified in subheading 2916.11.10 of the NCM; and

Description: Crude or glacial acrylic acid (also referred to as acroleic acid, ethylenecarboxylic acid, propenoic acid, 2-propenoic acid, and vinylformic acid).

  • Dumping margins for initiation purposes:

China:

Absolute dumping margin: US$ 48/t; and

Relative dumping margin: 9%.

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 October 8th, 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.
