9902.02.28 - 4,4'-(1,1-Butanediyl)bis[5-methyl-2-(2-methyl-2-propanyl)phenol] (CAS No. 85-60-9) (provided for in subheading 2907.29.90)

This HTS classification pertains to a specific chemical compound, 4,4'-(1,1-Butanediyl)bis[5-methyl-2-(2-methyl-2-propanyl)phenol], identified by CAS Number 85-60-9. While this subheading exists within Chapter 99, which generally addresses temporary legislation and trade agreement modifications, its direct reference to subheading 2907.29.90 indicates its primary classification under phenolic compounds. The substance itself is a bisphenol, characterized by two phenolic rings connected by a butanediyl group, with methyl and tert-butyl substituents.

Distinguishing this entry from other categories at the same level within the HTS database is crucial for accurate import/export processing. Unlike the broad scope of Chapter 99 which can encompass diverse temporary measures for various goods, this specific code is tailored to this single chemical. Its focus is not on general categories like live animals (Chapters 01), but on the precise identification and temporary treatment of a specialized organic chemical. The inclusion within Chapter 99 signifies that its import treatment may be subject to specific, potentially time-limited, trade policies or restrictions that deviate from its permanent HTS classification.

As this is a leaf node, there are no further subcategories. This means that any goods falling under this HTS code 9902.02.28 will be classified directly and definitively as the specified chemical compound. Classification at this level relies on confirming the identity of the imported substance through technical specifications, chemical analysis, or provided documentation that matches the chemical name and CAS number. The reference to subheading 2907.29.90 provides the underlying permanent classification for this phenolic compound, while 9902.02.28 designates a specific, temporary trade provision applicable to it.
