9902.08.36 - Direct Blue 279 (4-N-(5,8-dimethoxy-2,4-dimethylquinolin-6-yl)-1-N,1-N-diethylpentane- 1,4-diamine) (CAS No. 72827-89-5) (provided for in subheading 3204.14.50)

This HTS classification, 9902.08.36, specifically covers Direct Blue 279, a particular dye identified by its chemical name and CAS number. This entry falls under Chapter 99, which encompasses temporary legislation and special provisions. Its inclusion here signifies a specific, often temporary, duty or restriction applied to this dye, overriding its standard classification under Chapter 32 (Dyes and pigments). The "provided for in subheading 3204.14.50" parenthetically noted in the description indicates that while this is the primary classification for immediate customs processing, the underlying material is fundamentally a synthetic organic dye.

Distinguishing this category from its siblings within Chapter 99 is crucial. The sibling categories, such as those related to live animals (0101, 0102, etc.), are entirely distinct in their subject matter, addressing live animal imports. The "99" chapter is a broad area for various temporary or special import conditions, and each subcategory within it, like 9902.08.36, addresses a very specific commodity or situation requiring special tariff treatment.

As this is a leaf node, there are no further subcategories. Therefore, the focus remains on understanding the unique application and provisions associated with Direct Blue 279 under HTS code 9902.08.36. Importers and brokers should consult the specific regulations or proclamations referenced by this Chapter 99 code to understand the exact import requirements, such as any specific duties, quotas, or documentation that may apply to Direct Blue 279 beyond its general classification as a dye.
