On April 30th, 2026, the publication of SECEX Ordinance nº 34/2026, initiated an anti-dumping investigation on Brazilian imports of reciprocating compressors for refrigeration originating from China. The product is usually classified under subheading 8414.30.11 of the Mercosur Common Nomenclature (NCM).
The opening of the investigation was motivated by a petition filed on October 31st, 2025, by Nidec Global Appliance Brasil Ltda. 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: Nidec Global Appliance Brasil Ltda.
- 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 subheading 30.11 of the NCM; and
Description: Reciprocating compressors for use with R600a refrigerant fluid, with capacity up to 350 watts (equivalent to 301 frigorias/hour), under the ASHRAE LBP (Low Back Pressure) condition.
- Dumping margins for initiation purposes: the authorities considered that market economy conditions do not prevail in the Chinese reciprocating compressor production segment. The margin was calculated using Mexico as the surrogate third country.
Absolute dumping margin: US$ 33/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 May 25th, 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.
