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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically modified beyond polysaccharide derivative criteria
Cellulose ethers like CMC can shift to synthetic cellulose derivatives if modifications don't meet natural polymer purity rules.
If for industrial-grade dextrin derivatives
Similar polysaccharide products like dextrins classify here if primarily used as adhesives rather than general primary forms.

Import Tips & Compliance
• Verify purity and derivative status via certificate of analysis to confirm polysaccharide base and avoid reclassification to synthetic polymers
• Ensure documentation specifies 'primary form' (e.g
• powder <95% processed) to prevent shifts to finished goods headings

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.
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.
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.
