6112.19.40.30 - Men's or boys' (738)

This HTS code, 6112.19.40.30, specifically classifies men's or boys' track suits that are knitted or crocheted and are composed of textile materials other than cotton, synthetic fibers, or artificial fibers. The key defining characteristic for this subcategory is that the track suits must contain 70 percent or more by weight of silk or silk waste. This precise material composition is crucial for distinguishing these garments from other track suits within the broader category.

The distinction between this code and its sibling, 6112.19.40.40, lies solely in the intended wearer. While both codes fall under track suits of other textile materials containing 70 percent or more silk or silk waste, this particular code is exclusively for items designed for men or boys, whereas the sibling code pertains to women's or girls' garments.

As this is a leaf node in the HTS classification system, there are no further subcategories. Therefore, the classification terminates with the identification of men's or boys' track suits meeting the specified silk content criteria. When classifying, it is essential to verify the weight percentage of silk or silk waste to ensure accurate placement under this code.
