9902.11.47 - Poly(toluene diisocyanate) (CAS No. 26006-20-2) (provided for in subheading 3911.90.45)

This HTS classification, 9902.11.47, specifically covers Poly(toluene diisocyanate) (CAS No. 26006-20-2). This classification falls under Chapter 99, which is reserved for temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions. The primary purpose of this code is to track and potentially restrict imports of this specific chemical compound, which is provided for in subheading 3911.90.45 of the HTS.

While this is a "leaf node" within the HTS database, meaning it has no further subcategories, it is crucial to understand its context. Its parent category, Section XXII, deals with special provisions and temporary measures. Therefore, this classification is not based on the inherent nature or general use of the chemical, but rather on specific import regulations or trade policy that may be in effect at a given time. The mention of its provision under subheading 3911.90.45 indicates that it is also classified under a general heading for other polymers of aromatic compounds, but this Chapter 99 code imposes an additional layer of control or monitoring.

Therefore, when classifying Poly(toluene diisocyanate), it is essential to consider both its general classification within the chemical chapters of the HTS and any applicable temporary legislation or restrictions that may be in effect under Chapter 99. This specific code ensures that imports of this particular substance are subject to scrutiny beyond its standard tariff classification, likely due to trade agreements, national security, or other policy considerations.
