NCM 69.03 – Other refractory ceramic goods

About NCM heading 69.03

Ceramic goods; (e.g. retorts, crucibles, muffles, nozzles, plugs, supports cupels, tubes, pipes, sheaths, rods and slide gates) excluding those of siliceous fossil meals or of similar siliceous earths

Heading 69.03 of Brazil's NCM has 17 eight-digit codes. Official Portuguese description: Outros produtos cerâmicos refratários (por exemplo, retortas, cadinhos, muflas, bocais, tampões, suportes, copelas, tubos, mangas, varetas, "portas" deslizantes (slide gates)) que não sejam de farinhas siliciosas fósseis nem de terras siliciosas semelhantes.
