Mucilages & Thickeners from Vegetable Products (Other)

Carrageenan's commercial volume and distinct chemical identity — a sulfated polysaccharide from red algae — warranted a dedicated 10-digit line (1302390010) within the US schedule, allowing Customs to track it separately from other NESOI thickeners. This also facilitates targeted trade-remedy or admissibility actions specific to carrageenan without affecting other products in the heading.

FDA Prior Notice is required for all food-ingredient shipments. Importers should also have a Certificate of Analysis confirming identity and purity, supplier FSVP documentation under the Food Safety Modernization Act, and, for carrageenan, clarity on whether the product is food-grade (carrageenan) or degraded (poligeenan), as the latter is not permitted in food.
