Products classified under HTS 3912.39.00.00
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.
Hydroxypropyl Cellulose (HPC)
HPC is a derivative used in tablet coatings, hot-melt extrusion, and cosmetics for film-forming properties. Classified in HTS 3912.39.00.00 as other cellulose ethers based on hydroxypropyl predominance.
Methyl Hydroxyethyl Cellulose
A mixed cellulose ether combining methyl and hydroxyethyl groups for use in plasters and adhesives. HTS 3912.39.00.00 applies as copolymers classified by predominant comonomer units.
Cyanoethyl Cellulose Ether
Specialty cellulose ether with cyanoethyl groups for electronic applications and adhesives. Falls under HTS 3912.39.00.00 as other ethers where modification doesn't trigger specific subheading.
Quaternary Ammonium Cellulose Ether
Cationic cellulose ether used in paper manufacturing and water treatment as flocculant. HTS 3912.39.00.00 for other derivatives meeting polymer content rules.
Allyl Cellulose Ether
Allyl-modified cellulose ether for crosslinking applications in coatings. Primary form classification under HTS 3912.39.00.00 as other cellulose ethers.
Benzyl Cellulose Ether
Benzyl ether derivative used in specialty resins and adhesives. HTS 3912.39.00.00 covers as chemically modified cellulose ether per subheading notes.
Hydroxypropyl Guar/Cellulose Blend
Polymer blend classified as cellulose ether when cellulose units predominate, used in fracking fluids. HTS 3912.39.00.00 per blend classification rules.
Pharmaceutical Grade HEC USP
USP-compliant hydroxyethyl cellulose for drug formulations meeting pharmacopeia standards. Primary form under HTS 3912.39.00.00 as other cellulose ethers.
Food Grade Methylcellulose E461
E461 approved methylcellulose for processed foods as stabilizer. HTS 3912.39.00.00 for primary form food additive cellulose ether.
