Products classified under HTS 3824.99.32.00
Sodium Hydrosulfite Dye Vat Discharge Agent
A chemical mixture containing sodium hydrosulfite (Na2S2O4) used in textile dyeing to discharge color from vat dyes, creating white patterns on indigo-dyed denim. This preparation falls under HTS 3824.99.32.00 as a mixture of hydrosulfite compounds with other inorganic substances for industrial textile processing.
Zinc Formaldehyde Sulfoxylate Bleaching Powder
A dry powder formulation of zinc sulfoxylate formaldehyde (Zn(CHO)2SO2) mixed with stabilizers, used for bleaching and discharging in printing textiles and paper. Classified under HTS 3824.99.32.00 due to its sulfoxylate compound content in an inorganic mixture designed for industrial decolorization.
Hydrosulfite-Sulfoxylate Textile Discharge Paste
Thickened paste combining sodium hydrosulfite and sodium formaldehyde sulfoxylate for screen printing discharge effects on fabrics. This dual-compound inorganic mixture is specifically classified under HTS 3824.99.32.00 for its hydrosulfite and sulfoxylate composition.
Industrial Sodium Dithionite Reducing Solution
Aqueous solution of sodium dithionite (hydrosulfite) with inorganic buffers for vat dyeing reduction in textile mills. Falls under HTS 3824.99.32.00 as a mixture of hydrosulfite compounds with other inorganic substances for chemical processing.
Sulfoxylate Bleach for Paper Manufacturing
Mixture containing sodium sulfoxylate with inorganic activators used in paper pulp bleaching processes to remove color impurities. Classified in HTS 3824.99.32.00 specifically for sulfoxylate compound mixtures in industrial applications.
Denim Discharge Printing Hydrosulfite Paste
Specialty paste of sodium hydrosulfite compounded with inorganic thickeners for creating white discharge prints on indigo denim fabric. This preparation qualifies under HTS 3824.99.32.00 as containing hydrosulfite compounds in mixture form.
Formaldehyde-Sulfoxylate Reducing Agent
Industrial reducing agent combining formaldehyde sulfoxylate with inorganic salts for leather dyeing and finishing processes. Covered by HTS 3824.99.32.00 for sulfoxylate-based inorganic compound mixtures.
Hydrosulfite Stabilized Powder for Dyeing
Stabilized sodium hydrosulfite powder mixed with inorganic carbonates and silicates to prevent decomposition during textile dyeing operations. Classified under HTS 3824.99.32.00 as hydrosulfite compound mixtures.
