9902.02.30 - 4,4',4''-(1,1,3-Butanetriyl)tris[5-methyl-2-(2-methyl-2-propa- nyl)phenol] (CAS No. 1843-03-4) (provided for in subheading 2907.29.90)

HTS Code 9902.02.30 represents a specific chemical compound, 4,4',4''-(1,1,3-Butanetriyl)tris[5-methyl-2-(2-methyl-2-propa- nyl)phenol], identified by CAS Number 1843-03-4. This classification falls under Chapter 99, which encompasses temporary legislation and modifications. Therefore, the presence of goods under this code signifies a special import provision, often temporary in nature, related to this particular chemical.

This category is unique and does not have direct siblings at the HTS database root level that cover similar chemical compounds. Its placement in Chapter 99 distinguishes it significantly from the primary commodity chapters (like Chapters 1-89), which cover goods based on their material composition and intended use for general trade. The "provided for in subheading 2907.29.90" note indicates that the underlying chemical would typically be classified under the general provisions for phenols and their derivatives, but for specific, temporary reasons, it is managed through this Chapter 99 provision.

As a leaf node, HTS Code 9902.02.30 does not have further subcategories. Classification within this specific code is definitive for the described chemical. Its purpose is to control or monitor the importation of this particular substance, likely due to temporary trade agreements, policy adjustments, or specific regulatory requirements, rather than its inherent physical characteristics or general commercial use as seen in other HTS chapters.
