9902.12.90 - High tenacity single yarn of viscose rayon, with a decitex less than 1,000 (provided for in subheading 5403.10.30)

This HTS classification, 9902.12.90, pertains to high tenacity single yarns of viscose rayon with a decitex less than 1,000. These are specialized yarns designed for applications requiring exceptional strength and durability. The "provided for in subheading 5403.10.30" notation indicates that these yarns are specifically referenced and potentially subject to the provisions outlined within that particular HTS subheading, which typically deals with synthetic filament yarns.

Unlike sibling categories which cover a broad spectrum of goods from live animals to processed agricultural products, 9902.12.90 is highly specific, focusing on a particular type of man-made filament yarn. The key distinguishing factors are the material (viscose rayon), its physical characteristic (high tenacity), and its structural form (single yarn), along with a specific decitex range. This level of detail ensures accurate classification for specialized textile inputs.

As a leaf node, this category does not have further subcategories. Therefore, its utility lies in its precise definition for the direct classification of these high-tenacity viscose rayon yarns. Importers and exporters will use this code to ensure compliance with any specific duties, quotas, or regulations associated with this particular type of textile raw material, especially as it falls under temporary legislation or trade agreement provisions indicated by Chapter 99.
