6103.39.10.00 - Of artificial fibers (633)

This HTS classification covers suit-type jackets and blazers for men or boys that are knitted or crocheted and are made from textile materials other than those specified in higher-level subheadings. Specifically, this category pertains to garments constructed from artificial fibers. Examples would include blazers or suit jackets manufactured from materials such as polyester, nylon, acrylic, or rayon, when these fabrics comprise the primary component and the garment is knitted or crocheted.

This classification is distinct from its sibling categories. It is differentiated from 6103.39.40.00, which specifically covers garments containing 70 percent or more by weight of silk or silk waste. Furthermore, it stands apart from the broader "Other" category (6103.39.80) by its explicit material composition of artificial fibers. The key differentiating factor is the exclusive reliance on synthetic or man-made fibers as the constituent textile material for these knitted or crocheted jacket and blazer articles.

As a leaf node, this classification does not have further subcategories. Therefore, the classification criteria are solely based on the garment type (suit-type jackets and blazers), the manufacturing method (knitted or crocheted), and the primary material content (artificial fibers). Proper identification hinges on confirming the knitted or crocheted construction and the presence of artificial fibers as the principal component, while excluding silk-based garments covered under sibling entries.
