Products classified under Tariff item 3912.39.00
Allyl Cellulose Ether
Allyl cellulose ether is a chemically modified cellulose ether where allyl groups are appended to the cellulose backbone. It is used as a crosslinking agent in coatings and falls under tariff item 3912.39.00 as an 'other' cellulose ether, not elsewhere specified.
Benzyl Cellulose Ether
Benzyl cellulose ether is a cellulose ether derivative with benzyl groups, used in specialty resins and adhesives. It is classified under tariff item 3912.39.00 as an 'other' cellulose ether, as it is not specifically named in other subheadings.
Carboxymethyl Cellulose (CMC)
Carboxymethyl cellulose (CMC) is a cellulose ether produced by reacting cellulose with sodium hydroxide and chloroacetic acid. It is used as a thickener in food, pharmaceuticals, and industrial applications, and falls under tariff item 3912.39.00 as an 'other' cellulose ether.
Cyanoethyl Cellulose Ether
Cyanoethyl cellulose ether is a specialty cellulose ether with cyanoethyl groups, used in electronic applications and adhesives. It falls under tariff item 3912.39.00 as an 'other' cellulose ether, as the modification does not trigger a more specific subheading.
Ethylcellulose Granules
Ethylcellulose granules are an ethyl ether derivative of cellulose, used as a coating agent in tablets and in inks. They fall under tariff item 3912.39.00 as 'other' cellulose ethers in primary granular form, compliant with polymer predominance rules.
Food Grade Methylcellulose E461
Food grade methylcellulose E461 is a methyl ether of cellulose approved as a food additive (E461) for use as a stabilizer. It falls under tariff item 3912.39.00 as an 'other' cellulose ether in primary form, specifically for food additive applications.
Hydroxyethyl Cellulose (HEC)
Hydroxyethyl cellulose (HEC) is a non-ionic water-soluble cellulose ether used in paints, cosmetics, and construction as a thickener and stabilizer. It is classified under tariff item 3912.39.00 as an 'other' cellulose ether in primary forms.
Hydroxypropyl Cellulose (HPC)
Hydroxypropyl cellulose (HPC) is a derivative used in tablet coatings, hot-melt extrusion, and cosmetics for film-forming properties. It is classified under tariff item 3912.39.00 as an 'other' cellulose ether based on hydroxypropyl predominance.
Hydroxypropyl Guar/Cellulose Blend
Hydroxypropyl guar/cellulose blend is a polymer blend classified as a cellulose ether when cellulose units predominate. It is used in fracking fluids and falls under tariff item 3912.39.00 per blend classification rules.
Hydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methylcellulose (HPMC) is a semisynthetic cellulose ether combining hydroxypropyl and methyl groups, widely used in pharmaceuticals, construction mortars, and vegan capsules. It falls under tariff item 3912.39.00 as an 'other' cellulose ether, classified by predominant comonomer units.
Methylcellulose Powder
Methylcellulose powder is a methyl ether of cellulose used in food as a thickener and in pharmaceuticals for controlled-release tablets. It qualifies for tariff item 3912.39.00 as a primary form cellulose ether where methyl groups predominate.
Methyl Hydroxyethyl Cellulose
Methyl hydroxyethyl cellulose is a mixed cellulose ether combining methyl and hydroxyethyl groups for use in plasters and adhesives. Tariff item 3912.39.00 applies as copolymers classified by predominant comonomer units.
Pharmaceutical Grade HEC USP
Pharmaceutical grade HEC USP is a USP-compliant hydroxyethyl cellulose for drug formulations meeting pharmacopeia standards. It falls under tariff item 3912.39.00 as an 'other' cellulose ether in primary form.
Quaternary Ammonium Cellulose Ether
Quaternary ammonium cellulose ether is a cationic cellulose ether used in paper manufacturing and water treatment as a flocculant. It falls under tariff item 3912.39.00 as an 'other' derivative meeting polymer content rules.
Sodium Carboxymethyl Cellulose (NaCMC)
Sodium carboxymethyl cellulose (NaCMC) is a cellulose ether derivative used in detergents, food, and oil drilling. It fits tariff item 3912.39.00 as an 'other' cellulose ether when ether content meets general criteria.
