9902.13.32 - Artificial staple fibers, not carded, combed or otherwise processed for spinning; of viscose rayon, such fibers containing between 28 percent and 33 percent by weight of silica, measuring 2.2 decitex in 38 mm lengths (provided for in subheading 5504.10.00)

This HTS code, 9902.13.32, pertains to a very specific type of artificial staple fiber, namely viscose rayon. The defining characteristics for this classification are that the fibers are not processed for spinning (i.e., they are not carded, combed, or otherwise prepared for yarn production). Furthermore, these fibers must contain a precise weight percentage of silica, specifically between 28% and 33%, and measure 2.2 decitex in length with a 38 mm staple length. These fibers are provided for in subheading 5504.10.00, indicating that this 9902 code represents a temporary modification or restriction applied to goods that would otherwise fall under that primary subheading.

As this is a leaf node within Chapter 99, it represents a specific, temporary provision and does not have further subcategories. Its purpose is to impose special classification treatment, likely due to trade agreements or specific import restrictions, on the described viscose rayon staple fibers. Unlike the numerous sibling categories beginning with "0101" and continuing through the live animal chapters, this category deals with manufactured textile materials rather than live animals, highlighting the broad scope of Chapter 99 to temporarily modify or control the classification and import of diverse goods. The specificity of the silica content, decitex, and staple length are crucial for correctly applying this temporary classification provision.
