Yes — line 6203431110 covers ski and snowboard pants for men and boys that are water-resistant and made of synthetic fibers with less than 36% wool or fine animal hair. Importers of technical outerwear should verify that the garment meets the water-resistance standard required for this classification.
CBP looks for evidence that the outer shell has been treated or constructed to resist water penetration, typically demonstrated by a mill test report referencing a recognized standard (such as AATCC or ISO water-resistance tests). Without supporting documentation, the goods may be reclassified into the non-water-resistant overalls lines, which can carry different duty rates.
