On November 14th, 2025, the publication of SECEX Ordinance nº 90/2025, initiated an anti-dumping investigation on Brazilian imports of seamless carbon steel pipes (line pipes) used in oil or gas pipelines, with an external diameter not exceeding five (5) nominal inches (141.3 mm), originating from Malaysia, India, and Thailand. The product is usually classified under subheading 7304.19.00 of the Mercosur Common Nomenclature (NCM).

The opening of the investigation was motivated by a petition filed on April 30th, 2025, by Vallourec Soluções Tubulares do Brasil 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: Vallourec Soluções Tubulares do Brasil S.A.
  • Origin: Malaysia, India, and Thailand.

  • Period of investigation:

Dumping: January 2024 to December 2024; and

  • Product under investigation:

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 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.
