9902.08.26 - Acid Brilliant Blue FCF FOOD Blue No. 1 (Acid Blue 9) (disodium 2-({4-[ethyl(3-sulfonatobenzyl)amino]phenyl} {4- [ethyl(3-sulfonatobenzyl)iminio]cyclohexa-2,5-dien-1-ylidene}methyl) ben- zenesulfonate) (CAS No. 3844-45-9) (provided for in subheading 3204.12.50)

This HTS category, 9902.08.26, specifically covers Acid Brilliant Blue FCF, also known as Food Blue No. 1 or Acid Blue 9. The detailed chemical name provided, disodium 2-({4-[ethyl(3-sulfonatobenzyl)amino]phenyl}{4-[ethyl(3-sulfonatobenzyl)imino]cyclohexa-2,5-dien-1-ylidene}methyl)benzenesulfonate, with CAS number 3844-45-9, precisely identifies this synthetic organic dye. Its inclusion in Chapter 99 signifies it is subject to temporary legislation or additional import restrictions, often related to specific trade agreements or Section 22 of the Agricultural Adjustment Act.

Unlike the broad categories of live animals found in the sibling nodes such as live horses (0101) or bovine animals (0102), this classification pertains to a highly specific chemical compound. Its purpose is primarily as a colorant, particularly for food applications, which distinguishes it from other dyes or chemicals that might fall under Chapter 32 (Dyes and pigments) if not for the specific temporary provisions invoked here. The reference to subheading 3204.12.50 under which it is "provided for" indicates its underlying nature as a synthetic dyestuff, but the 9900 series designation overrides or supplements the standard classification with temporary trade or regulatory measures.

As a leaf node within the HTS, there are no further subcategories under 9902.08.26. Therefore, the focus for classification purposes under this heading is on confirming the identity of the imported article as Acid Brilliant Blue FCF, and ensuring compliance with any associated temporary restrictions or requirements dictated by the Chapter 99 provisions. This classification is critical for importers to accurately declare goods and adhere to all applicable trade regulations.
