6210.30.90.40 - Having a fiber content of 70 percent or more by weight of silk or silk waste (735)

This HTS classification, 6210.30.90.40, specifically covers anoraks, windbreakers, and similar articles made from fabrics described in headings 5602, 5603, 5903, 5906, or 5907. The defining characteristic of this particular subcategory is that the garment must have a fiber content of 70 percent or more by weight of silk or silk waste. These are typically outer garments designed for protection against wind and light rain, often featuring a hood and full-length closure.

This code is distinguished from its sibling category, 6210.30.90.49, by its strict material composition requirement. While both fall under "Other" anoraks and similar articles within the broader "Other garments, of the type described in heading 6202" parent context, 6210.30.90.40 is exclusively for articles where silk or silk waste constitutes at least 70% of the fabric weight. The sibling category, 6210.30.90.49, would encompass all other anoraks and similar articles that do not meet this specific silk content threshold.

As this classification is a leaf node within the HTS, there are no further subdivisions. Therefore, classification under 6210.30.90.40 relies solely on the garment's design (anorak, windbreaker, or similar) and the explicit requirement of a fiber content of 70 percent or more by weight of silk or silk waste. Any variation in material composition below this threshold would necessitate classification under a different HTS code.
