6114.90.90.55 - Subject to man-made fiber restraints (659)

This HTS category, 6114.90.90.55, covers knitted or crocheted garments and clothing accessories that are not made of cotton, wool, or other specific textile materials designated by restraints. The key defining characteristic for this classification is that the garments are subject to man-made fiber restraints, as indicated by the "(659)" notation. These restraints are import limitations, and their presence is crucial for proper classification.

This category is specifically distinguished from its sibling categories by the type of fiber restraints applied. While 6114.90.90.45 covers garments subject to cotton restraints and 6114.90.90.50 pertains to those under wool restraints, 6114.90.90.55 exclusively addresses items with man-made fiber limitations. The "Other (859)" category at the same level is for garments that do not fall under any of these specific fiber restraint categories.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Therefore, the classification decision rests entirely on identifying that the garment is knitted or crocheted, is not of cotton or wool, is made from textile materials subject to import restraints, and specifically falls under the man-made fiber restraint designation. Importers must consult the relevant trade agreements or official notices for the specific details and scope of the man-made fiber restraints.
