9902.13.49 - Men's or boys' knitted or crocheted sweaters of linen, each with 9 or fewer stitches per 2 centimeters measured in the direction the stitches were formed (provided for in subheading 6110.90.90).

This HTS category, 9902.13.49, specifically classifies men's or boys' knitted or crocheted sweaters made from linen. A key distinguishing feature for inclusion under this provision is the stitch density: the fabric must contain 9 or fewer stitches per 2 centimeters, measured in the direction the stitches were formed. These sweaters are classified under the broader scope of Section XXII, which deals with temporary legislation and modifications.

The "99" chapter of the HTS system signifies temporary provisions, often enacted due to trade agreements or specific legislative actions like Section 22 of the Agricultural Adjustment Act. Therefore, this particular classification is not a permanent part of the standard HTS structure but rather a temporary adjustment applied to a specific type of linen garment. It exists to implement specific trade policies or restrictions related to these goods.

Given that this is a leaf node within the HTS database, there are no further subcategories. The classification is final at this level, meaning that any men's or boys' knitted or crocheted sweater of linen meeting the specified stitch count will fall under 9902.13.49. It is crucial for importers to verify both the material composition (linen) and the precise stitch density to ensure accurate classification under this temporary provision, as opposed to other general categories for knit or crochet apparel that may exist elsewhere in the permanent HTS structure.
