Guar Gum Powder
Guar gum, derived from guar beans, is a galactomannan polysaccharide used in food, fracking, and textiles. HTS 3913.90.20.90 covers it as a primary form powder of polysaccharide derivatives. Classification relies on its natural plant origin and lack of further specification.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for unmodified plant extracts
Raw guar gum extracts fall under vegetable saps/mucilages in 1302 before polymer processing.
If not purely polysaccharide-based
Other natural polymers not polysaccharides go to the residual 3913.90.90.

Import Tips & Compliance
• Test for galactomannan content >95% to meet polymer predominance rules in subheading notes
• Document as 'native guar gum' not 'modified' if partially hydrolyzed

Sodium Carboxymethyl Cellulose Powder
Sodium carboxymethyl cellulose (CMC) is a cellulose derivative used as a thickener in food, pharmaceuticals, and detergents. It falls under HTS 3913.90.20.90 as a polysaccharide derivative in primary form (powder), not elsewhere specified. This classification applies to its unmodified primary state before further processing.
Hydroxypropyl Methylcellulose Granules
Hydroxypropyl methylcellulose (HPMC) is a semi-synthetic polysaccharide derivative used in pharmaceuticals for capsule shells and as a thickener. Classified under HTS 3913.90.20.90 as a modified natural polysaccharide in primary granular form. It qualifies due to its cellulose base and primary (non-formulated) state.
Xanthan Gum Powder
Xanthan gum is a polysaccharide produced by bacterial fermentation of glucose, used as a stabilizer in food and oil drilling. It is classified in HTS 3913.90.20.90 as a natural polysaccharide derivative in primary powder form, not specified elsewhere. This covers its raw, unprocessed state.
Sodium Alginate Powder
Sodium alginate is a polysaccharide salt from brown seaweed, used in food gelling and biotech. Though alginates have specific provisions, certain derivatives fall under HTS 3913.90.20.90 as other polysaccharides in primary powder form. This applies to modified versions not purely under alginic acid headings.
Carboxymethyl Starch Powder
Carboxymethyl starch is a starch derivative used as a binder in paper and pharma tablets. It is classified under HTS 3913.90.20.90 as a polysaccharide derivative in primary powder form. Meets criteria as modified natural polymer not elsewhere specified.
Pectin Powder
Pectin is a fruit-derived polysaccharide used for gelling in jams and as a stabilizer. HTS 3913.90.20.90 includes it as a primary form powder when not specifically under other provisions. Natural origin and primary state govern classification.
