6204.33.10.00 - Containing 30 percent or more by weight of silk or silk waste (635)

This HTS category, 6204.33.10.00, specifically classifies suit-type jackets and blazers for women or girls that are constructed from synthetic fibers and contain 30 percent or more by weight of silk or silk waste. This material composition is the defining characteristic, distinguishing these garments from other jackets and blazers within the broader synthetic fiber category.

Unlike sibling categories such as 6204.33.20.00 which focuses on flax fiber content, or 6204.33.40 which addresses wool or fine animal hair, this classification exclusively addresses those predominantly synthetic garments incorporating a significant proportion of silk. The "other" category, 6204.33.50, serves as a residual for synthetic suit-type jackets and blazers that do not meet the specific material percentages of the preceding subheadings.

As a leaf node, this HTS code represents the most granular level of classification for this particular item. Therefore, there are no further subcategories. The classification hinges solely on the garment type (suit-type jackets and blazers), the intended wearer (women or girls), the primary material (synthetic fibers), and the specific percentage of silk or silk waste by weight.
