Carmine and cochineal extract are FDA-certified color additives subject to batch certification requirements when used in food, drugs, or cosmetics. Imported carmine food color solutions under line 3205000500 must comply with FDA's color additive regulations, and shipments may be subject to FDA examination at the port of entry. Importers should ensure the product is accompanied by documentation confirming compliance with the applicable FDA specification. Classification and admissibility are complex; consult a licensed customs broker or FDA prior to import.

The classification of a color lake preparation depends on whether the lake itself imparts the essential character. Lakes on alumina, barium sulfate, or calcium substrates generally remain in 3205 regardless of the substrate, but heavily formulated products — such as a lake dispersed in a wax or resin at low pigment concentration — may shift to a different heading. The hue and whether the product is described in Chapter Note 3 or Additional U.S. Note 3 to Section VI further determine the applicable 10-digit line.
