6203.19.50.00 - Containing 70 percent or more by weight of silk or silk waste (743)

This HTS classification covers men's or boys' suits that are not knitted or crocheted and are primarily composed of textile materials other than cotton or artificial fibers, specifically where silk or silk waste constitutes 70 percent or more by weight. These garments are designed for formal or semi-formal wear and are typically sold as a coordinated set, often including a jacket and trousers. The emphasis on a high silk content is a key defining characteristic for classification within this code.

This category is distinguished from its siblings by its specific material composition. HTS code 6203.19.10 specifically covers suits made of cotton. Another sibling category, 6203.19.90, encompasses suits made from "other" textile materials not otherwise specified, which would include blends where silk is present but does not meet the 70% threshold, or suits made from entirely different materials. This node, 6203.19.50.00, exclusively targets suits where silk or silk waste is the dominant fiber.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, classification under 6203.19.50.00 is determined solely by the presence of men's or boys' suits (as defined in the parent categories) where at least 70% of the weight is derived from silk or silk waste, and not primarily from cotton or artificial fibers. This precise material composition is crucial for accurate customs declaration.
