On July 6th, 2026, the publication of SECEX Ordinance nº 51/2026, initiated an anti-dumping investigation on Brazilian imports of welded line pipe, of circular cross-section, of carbon steel, with a yield strength below 60 ksi and a nominal outside diameter equal to or greater than 14″ (355.6 mm) and not exceeding 48″ (1,219.2 mm), regardless of wall thickness or end type, originating from China. The product is usually classified under subheadings 7305.11.00, 7305.12.00, 7305.19.00, 7305.31.00, 7305.39.00, 7306.19.00 and 7306.30.00 of the Mercosur Common Nomenclature (NCM).

The opening of the investigation was motivated by a petition filed on October 31st, 2025, by Confab Industrial 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: Confab Industrial S.A.
  • Origin: China
  • Period of investigation:

Dumping: July 2024 to June 2025; and

Injury: July 2020 to June 2025.

  • Product under investigation:

Classification: usually classified under subheadings 11.00, 7305.12.00, 7305.19.00, 7305.31.00, 7305.39.00, 7306.19.00 and 7306.30.00 of the NCM; and

Description: welded line pipe, of circular cross-section, of carbon steel, with a yield strength below 60 ksi and a nominal outside diameter equal to or greater than 14″ (355.6 mm) and not exceeding 48″ (1,219.2 mm), regardless of wall thickness or end type (plain-cut, beveled, threaded, etc.), excluding tubes/pipes with an end welded to a connector or shoe, whether coated or uncoated and/or with surface treatment (such as paint or oil), excluding pipes with an external three-layer polyethylene (3LPE) coating.

  • Dumping margin for initiation purposes, based on the normal value in a surrogate country (United States of America) and the export price:

China:

Absolute dumping margin: US$ 1,213.51/t; and

Relative dumping margin: 67%.

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 27th, 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.
