On July 24th, 2026, the publication of SECEX Circular nº 60/2026 initiated a sunset review of the anti-dumping duty applied to Brazilian imports of cylinders for CNG, originating from China. The product under review is usually classified under subheading 7311.00.00 of the Mercosur Common Nomenclature (NCM).
The anti-dumping duties were originally applied by CAMEX Resolution No. 225, dated July 23, 2021.
The current review was motivated by a petition filed by Mat Equipamentos para Gases Ltda. on March 26th, 2026. After a preliminary analysis, the Foreign Trade Secretariat (SECEX), through the Department of Trade Remedies (DECOM), recommended the initiation of the sunset review to verify the need for the extension of the anti-dumping duties applied to the mentioned CNG cylinders, in light of evidence suggesting that the termination of the measure would most likely lead to the recurrence of dumping in exports from China and the recurrence of injury.
SECEX concluded, for initiation purposes, that market economy conditions do not prevail in the Chinese productive segment and adopted India as a surrogate country for purposes of determining the normal value.
The main information regarding the review is summarized below:
- Petitioner: Mat Equipamentos para Gases Ltda.
- Origin: China
- Period of analysis:
Resumption of dumping: January to December 2025; and
Resumption of injury: January 2021 to December 2025.
- Product under review:
Classification: usually classified under subheading 7311.00.00 of the NCM; and
Description: seamless alloy steel cylinders (no weld/seam), designed for the storage or transportation of compressed natural gas (CNG), with an external diameter equal to or greater than 219 mm and not exceeding 406 mm, and a volumetric capacity equal to or greater than 20 liters and not exceeding 160 liters, excluding cylinders for cryogenic use, for compressed gases other than CNG, for acetylene, for liquefied gases, for LPG, for oxygen, for nitrogen, and industrial cylinders.
- Difference between the constructed normal value on a surrogate country (Poland) and the domestic industry’s price in the Brazilian domestic market:

The participation of interested parties — including domestic producers, importers, exporters and the Government of China — 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 notification to submit 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 August 17th, 2026.
The sunset review must be completed within 10 months, extendable for up to 2 additional months. The anti-dumping duties remain in force until the conclusion of the review and, if the initial claims are confirmed, may be renewed for another 5 years.
