Products classified under HTS 2916.13.00.00
Glacial Methacrylic Acid
Pure methacrylic acid (CH2=C(CH3)COOH) in undiluted form, a key unsaturated acyclic monocarboxylic acid used in polymer production. Classified under HTS 2916.13.00.00 as it matches the chemical definition of methacrylic acid without salts. Supplied as a corrosive liquid for industrial synthesis of acrylic resins.
Sodium Methacrylate
The sodium salt of methacrylic acid (CH2=C(CH3)COONa), explicitly covered under HTS 2916.13.00.00 as 'methacrylic acid and its salts'. Used in water-soluble polymers, superabsorbent polymers, and dispersants. White powder form typical for industrial applications.
Methacrylic Acid 50% Aqueous Solution
50% methacrylic acid in water, classified under HTS 2916.13.00.00 per Chapter note (d) allowing aqueous solutions of defined organic compounds. Used for safer handling in polymer emulsion production. Stabilized to prevent polymerization during transport.
Ammonium Methacrylate
Ammonium salt of methacrylic acid, covered by HTS 2916.13.00.00 as a methacrylic acid salt per Chapter 29 definitions. Volatile powder used in ion-exchange resins and temporary binders. Classifies with parent acid over general ammonium compounds.
Methacrylic Acid with Hydroquinone Stabilizer
Methacrylic acid stabilized with 250 ppm hydroquinone to prevent polymerization, allowed under HTS 2916.13.00.00 per Chapter note (f) for stabilizers necessary for preservation/transport. Standard industrial grade for acrylic sheet production.
Potassium Methacrylate
Potassium salt form of methacrylic acid, specifically included in HTS 2916.13.00.00. Used in specialty coatings and as reactive diluent in polymer formulations. Classifies as organic salt per Chapter 29 note 3(C).
Technical Grade Methacrylic Acid 99%
99% purity methacrylic acid for industrial polymerization, classified HTS 2916.13.00.00 as chemically defined organic compound allowing minor impurities. Primary raw material for PMMA, adhesives, and coatings.
Methacrylic Acid/Maleic Acid Copolymer Solution
Aqueous solution of methacrylic acid copolymers for scale inhibition, classified under HTS 2916.13.00.00 only if qualifying as Chapter 29 solution. Typically shifts to polymer headings but pure acid solutions remain here.
Lithium Methacrylate
Lithium salt of methacrylic acid used in battery electrolytes and specialty polymers, HTS 2916.13.00.00 as organic salt. High purity required for electrochemical applications.
Methacrylic Acid with MEHQ Inhibitor
Methacrylic acid inhibited with monomethyl ether hydroquinone (MEHQ), standard stabilizer under HTS 2916.13.00.00 Chapter note (f). 100-400 ppm typical for safe bulk transport.
Calcium Methacrylate
Calcium salt of methacrylic acid for dental materials and controlled-release fertilizers, HTS 2916.13.00.00. Classifies as organic salt rather than general calcium compounds.
Methacrylic Acid 70% in Water
70% methacrylic acid aqueous solution for emulsion polymerization, HTS 2916.13.00.00 per Chapter note (d). Higher concentration than standard shipping grades.
Zinc Methacrylate
Zinc salt of methacrylic acid used in rubber vulcanization and anti-corrosion coatings, HTS 2916.13.00.00. Organometallic characteristics but classifies as organic salt.
Methacrylic Acid Technical Grade Stabilized
Industrial methacrylic acid with phenolic stabilizer, HTS 2916.13.00.00 allowing transport stabilizers. 99.5% purity minimum for cast sheet production.
