3204.12.50.10 - FD&C red 40 (CAS No. 25956-17-6)

This HTS classification covers FD&C red 40, a synthetic organic coloring matter. Specifically, this entry pertains to a specific synthetic red dye, identified by its CAS Number 25956-17-6. These dyes are classified under Chapter 32, which deals with tanning or dyeing extracts, pigments, paints, varnishes, and related products. The scope is limited to synthetic organic coloring matter, excluding natural dyes or pigments.

Within the broader category of "Acid dyes, whether or not premetallized, and mordant dyes and preparations based thereon," this sub-sub-classification distinguishes itself by specifying FD&C red 40. Its sibling categories at this level, such as FD&C yellow 5 and FD&C yellow 6, represent different specific synthetic dyes with distinct chemical structures and color properties, each serving specific coloring applications. The "Other" category at this level is a residual category for synthetic organic coloring matter that does not fall under the specifically enumerated dyes like FD&C red 40, yellow 5, or yellow 6.

As this is a leaf node in the HTS database, there are no further subcategories. The classification concludes at FD&C red 40, meaning that any goods imported or exported under this code should specifically be this substance. Classification decisions at this level rely heavily on the precise chemical identity and registered CAS number of the coloring matter to ensure accurate tariff application and compliance with import/export regulations.
