Products classified under HTS 2934.20.20.00
Sodium 2-Mercaptobenzothiazole Powder
Pure sodium salt of 2-mercaptobenzothiazole, a heterocyclic compound containing a benzothiazole ring system, supplied as a fine white to pale yellow powder. This chemical is classified under HTS 2934.20.20.00 as it exactly matches the specified compound, whether or not chemically defined, per Chapter 29 notes. It serves as a key reagent in rubber vulcanization and corrosion inhibition.
2-Benzothiazolethiol Sodium Salt Flakes
Flake form of sodium 2-mercaptobenzothiazole, a benzothiazole ring-system compound used primarily as a rubber accelerator (MBTS precursor). Classified specifically under HTS 2934.20.20.00 per the tariff description for this exact sodium salt. Meets Chapter 29 requirements for separate chemically defined heterocyclic compounds.
MBTS Sodium Salt Technical Grade
Technical-grade sodium 2-mercaptobenzothiazole (98% purity), a direct precursor to delayed-action rubber accelerator MBTS. This compound features the benzothiazole ring with mercapto functionality, precisely matching HTS 2934.20.20.00. Excluded from other chapters per notes on heterocyclic specificity.
Sodium Mercaptobenzothiazolate Crystals
Crystalline sodium salt of 2-mercaptobenzothiazole, chemically defined heterocyclic compound for use in flotation reagents and antioxidants. Falls under HTS 2934.20.20.00 due to its exact structural match to the tariff subheading for benzothiazole ring compounds. Complies with Chapter 29 note (a) for separate organic compounds.
2-Benzothiazolethiol Sodium Salt Solution 50%
50% aqueous solution of sodium 2-mercaptobenzothiazole, where the solvent is added solely for safe transport per Chapter 29 note (d). Still classified as the pure compound under HTS 2934.20.20.00, not as a preparation, due to the specific allowance for dilutions. Used in water-based rubber processing.
Stabilized Sodium 2-Mercaptobenzothiazole
Sodium 2-mercaptobenzothiazole with added stabilizer for preservation, allowed under Chapter 29 note (f), maintaining classification in HTS 2934.20.20.00. This benzothiazole derivative is essential for polymer stabilization and metalworking fluids.
High-Purity 2-Mercaptobenzothiazole Sodium Salt
99+% purity sodium salt of 2-mercaptobenzothiazole, a lab-grade reagent featuring the unfused benzothiazole ring. Precisely HTS 2934.20.20.00 as a chemically defined heterocyclic compound per Chapter 29 scope. Used in pharmaceutical synthesis and research.
