Last updated: April 2026 dataGuar gum and locust bean gum (carob gum) are plant-derived polysaccharides that serve as high-performance thickeners and stabilizers in food processing, hydraulic fracturing fluids, paper manufacturing, and textile sizing. The US schedule distinguishes guar-seed-derived products (1302320020) from locust-bean-derived products (1302320040), a split that matters for end-use specification and supplier sourcing. India dominates guar gum supply globally, and its position as the leading US source reflects the concentration of Cyamopsis tetragonoloba cultivation in Rajasthan. Importers should confirm whether the product is native or chemically modified, as modified derivatives may classify differently outside this heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Heading 130232 covers mucilages and thickeners whether or not modified, but heavily derivatized products — such as hydroxypropyl guar or carboxymethyl locust bean gum — may be reclassified under Chapter 35 or Chapter 39 depending on the degree of chemical transformation and the resulting properties. Importers of modified grades should obtain a binding ruling or consult a licensed customs broker before entry.
No. Guar gum destined for hydraulic fracturing or industrial use is not subject to FDA food-additive review. However, the HTS classification is the same regardless of end use, so the commercial invoice and entry documentation should clearly state the intended industrial application to avoid unnecessary FDA examination at the port of entry.
