GPC carbon raiser for United States
Lingshou Jiushun supplies GPC recarburizer ZW01–ZW04 (S≤0.05%, N 100–300 ppm) for U.S.-bound orders. Landed duty depends on the HTS classification used by the importer; Jiushun does not publish a fixed U.S. duty rate. Confirm classification with your customs broker before the commercial invoice is final.
