Now open: Sunset Review of antidumping duties in force against Brazilian imports of ceramic foam filters from China

In brief

On 25 June 2025, SECEX (the Brazilian Secretariat of International Trade) initiated a sunset review on the antidumping duties in force against Brazilian imports of ceramic foam filters, commonly classified under the NCM code 6903.90.91 e 6903.90.99, from China.

This is a product used to filter liquid metals – such as aluminum, copper or iron for cast retaining inclusions and impurities that would constitute defects in the casting.

The duties remain in force during the sunset review and, at the end of the sunset review, may be extended for additional five years.

The original text of the Official Notice of Initiation of the antidumping investigation (in Portuguese) is available in the following link.

Interested parties can request to be admitted as parties in the investigation until 15 July 2025[1], provided that they demonstrate the extent to which they are affected by the imposition of the antidumping duty or its extension.
