Carboxymethyl Cellulose (CMC)
Carboxymethyl cellulose is a cellulose ether derivative produced by reacting cellulose with sodium hydroxide and chloroacetic acid, used as a thickener in food and pharmaceuticals. It falls under HTS 3912.39.00.00 as a cellulose ether not elsewhere specified, meeting the criteria for primary form polymers where the cellulose ether structure predominates.
Hydroxyethyl Cellulose (HEC)
Hydroxyethyl cellulose is a non-ionic water-soluble cellulose ether used in paints, cosmetics, and construction as a thickener and stabilizer. Classified under HTS 3912.39.00.00 as other cellulose ethers in primary forms, with the hydroxyethyl groups contributing over 95% by weight to the polymer content.
Methylcellulose Powder
Methylcellulose is a methyl ether of cellulose used in food as a thickener and in pharmaceuticals for controlled-release tablets. It qualifies for HTS 3912.39.00.00 as a primary form cellulose ether where methyl groups predominate over other comonomers.
Hydroxypropyl Methylcellulose (HPMC)
HPMC is a semisynthetic cellulose ether combining hydroxypropyl and methyl groups, widely used in pharmaceuticals, construction mortars, and vegan capsules. Under HTS 3912.39.00.00 as other cellulose ethers, classified by predominant monomer units per chapter notes.
Ethylcellulose Granules
Ethylcellulose is an ethyl ether derivative of cellulose used as a coating agent in tablets and in inks. It falls under HTS 3912.39.00.00 for other cellulose ethers in primary granular form, compliant with polymer predominance rules.
Sodium Carboxymethyl Cellulose (NaCMC)
Although specific, NaCMC fits 'other' if not purely matching carboxymethyl subheading specs; used in detergents, food, and oil drilling. HTS 3912.39.00.00 covers when ether content meets general criteria.
