On June 30th, 2026, the publication of SECEX Ordinance nº 49/2026 initiated an anti-dumping investigation on Brazilian imports of certain plasticizer esters (DOP, DOTP and DINP) originating from South Korea, Chile and Colombia. The product is usually classified under subheadings 2917.32.00, 2917.33.00 and 2917.39.31 of the Mercosur Common Nomenclature (NCM).

The opening of the investigation was motivated by a petition filed on October 29th, 2025, by Elekeiroz 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: Elekeiroz S.A.
  • Origin: South Korea, Chile and Colombia

  • Period of investigation:

Dumping: July 2024 to June 2025; and

Injury: July 2020 to June 2025.

  • Product under investigation:

Classification: usually classified under subheadings 32.00, 2917.33.00 and 2917.39.31 of the NCM; and

Description: plasticizer esters of the types Di-2-ethylhexyl phthalate (DOP, CAS 117-81-7), Di-2-ethylhexyl terephthalate (DOTP, CAS 6422-86-2) and Di-isononyl phthalate (DINP, CAS 28553-12-0).

  • Dumping margins for initiation purposes:

South Korea:

Absolute dumping margin: US$ 731.30/t; and

Relative dumping margin: 56.8%.

Chile:

Absolute dumping margin: US$ 1,374.82/t; and

Relative dumping margin:86.3%.

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 July 20th, 2026.

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.
