9902.10.20 - Preparations containing 5-amino-1,3-dihydro-2H-benzimidazol-2-one (CAS No. 95-23-8) (provided for in subheading 3809.91.00)

This classification, HTS Code 9902.10.20, pertains to specific chemical preparations containing 5-amino-1,3-dihydro-2H-benzimidazol-2-one (CAS No. 95-23-8). These preparations are designated for use as provided for in subheading 3809.91.00, which generally covers finishing agents for textiles, paper, leather, etc. The inclusion of the CAS number and reference to a primary subheading is crucial for precise identification, ensuring these particular preparations are distinct from other chemical substances or general finishing agents.

As this category is a leaf node within Chapter 99, it does not have further subdivisions. Its purpose is to apply temporary legislation or specific import restrictions to this particular chemical preparation, overriding or modifying the general classification found under subheading 3809.91.00. Therefore, the distinction from its sibling categories, which begin with chapter and heading numbers like 0101 (Live horses), lies fundamentally in its placement within Section XXII and Chapter 99. This chapter is reserved for special classification provisions, temporary modifications, and legislatively mandated import restrictions, rather than the general classification of goods by their nature or function found in earlier chapters.
