On June 24^th, 2025, the publication of SECEX Circular No. 46/2025 initiated a sunset review of the anti-dumping duties on Brazilian imports of refractory ceramic filters originating from China. The product under investigation is usually classified under subheadings 6903.90.91 and 6903.90.99 of the Mercosur Common Nomenclature (“NCM”).

The anti-dumping duties were originally applied by CAMEX Resolution No. 47, of July 3^rd, 2014, and renewed by CAMEX Resolution No. 64, of June 23^rd, 2020. The current review was motivated by a petition filed by Foseco Industrial e Comercial Ltda. 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 antidumping duties applied to imports of refractory ceramic goods, in light of evidence suggesting that the termination of the measure would most likely lead to the resumption of dumping in exports originating from China, and the recurrence of injury the resulting therefrom.

The main information of the process is summarized below:

• Petitioner: Foseco Industrial e Comercial Ltda.
• Origins: China.
• Period of Investigation:

Continuation/resumption of dumping: October 2023 to September 2024.
Continuation/resumption of injury to domestic industry: October 2019 to September 2024.

• Product under investigation:

Classification: Usually classified in subheadings 90.91 and 6903.90.99 of the NCM.
Description: Denominated as refractory ceramic filter, or ceramic foam filter, or ceramic sponge filter, or silicon carbide-based ceramic filter, or silicon carbide ceramic filter. The product is used for filtering liquid metals – such as aluminum, copper, or iron – in foundry processes. It comes in rectangular, square, or round shapes and is packaged in cardboard boxes weighing between 15 to 30 kg per box, depending on the size of the product.

• Dumping margins for initiation purposes:

Absolute dumping margin: US$ 4,65/kg
Relative dumping margin: 80,2%

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 (thirty) days from the date of the notification to send their responses. Parties not initially identified at the beginning of the proceeding, but who consider themselves interested may request to be admitted to the case by July 14^th, 2025.

The sunset review must be completed within 10 (ten) months, extendable for up to 2 (two) 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 (five) years.
