Products classified under HTS 3809.93.50.00
Chromium Tanning Agent for Leather
A synthetic chromium-based finishing agent used in the leather tanning process to cross-link collagen fibers, making leather durable and water-resistant. It falls under HTS 3809.93.5000 as a preparation specifically for leather industries, not elsewhere specified. This agent is applied during wet processing to achieve full-grain leather quality.
Synthetic Fatliquoring Oil for Leather
An emulsified oil preparation used to lubricate and soften leather during finishing, preventing cracking and improving suppleness. Classified under HTS 3809.93.5000 for leather industry preparations like fatliquors that enhance hide quality. Applied post-tanning to full-thickness leather.
Leather Degreasing Emulsion
A surfactant-based emulsion for removing natural fats from raw hides before tanning, essential in leather preparation. It qualifies for HTS 3809.93.5000 as a leather industry finishing preparation not specified elsewhere. Improves penetration of tanning agents.
Acrylic Resin Finishing Compound for Leather
A water-based acrylic resin used as a topcoat on finished leather to provide gloss, abrasion resistance, and water repellency. Falls under HTS 3809.93.5000 for other leather industry finishing products. Commonly applied by roller or spray in shoe leather production.
Sulfonated Oil for Leather Pickling
Sulfonated vegetable oil used in the pickling stage of leather processing to preserve hides and facilitate tanning. Classified in HTS 3809.93.5000 as a leather industry preparation. Delivers salt and acid in emulsified form for uniform hide treatment.
Protein Filler for Leather Finishing
A casein or collagen-based filler compound that plumps and fills leather grain during finishing for uniform thickness. HTS 3809.93.5000 covers such protein preparations for leather industries. Used on corrected grain leathers.
Neutralizing Agent for Leather Tanning
A buffered alkaline preparation used post-chrome tanning to adjust pH and lock in tannins for stable leather. Fits HTS 3809.93.5000 as other leather processing chemical. Prevents acid reversion in finished hides.
Wetting Agent for Leather Processing
Non-ionic surfactant blend that reduces surface tension in leather wet processing for better chemical penetration. HTS 3809.93.5000 for leather industry wetting preparations. Accelerates re-wetting of hides in multiple processing stages.
Leather Dye Fixative
A polymeric fixative that binds dyes to leather fibers, preventing crocking and improving wash fastness. Classified under HTS 3809.93.5000 as leather industry preparation analogous to mordants. Applied in finishing wet-end.
Antifoam Agent for Leather Processing
Silicone-based defoamer preventing foam buildup in leather tanning drums and finishing operations. HTS 3809.93.5000 for leather industry process aids. Maintains processing efficiency.
Leather Handle Modifier
Synthetic wax and polymer blend that modifies leather touch from stiff to soft/supple during finishing. Fits HTS 3809.93.5000 as leather finishing preparation. Used for automotive and upholstery leathers.
Enzyme Preparation for Leather Bating
Proteolytic enzyme blend for bating leather hides, removing non-fibrillar proteins for cleaner grain. HTS 3809.93.5000 covers enzymatic leather processing aids. Essential for high-quality full-grain leather.
Pull-Up Finish for Leather
Oil-in-resin emulsion creating 'pull-up' effect on aniline leather where stretching reveals lighter base color. Classified HTS 3809.93.5000 for specialty leather finishes. Popular for fashion and marine upholstery.
Leather Mildew Preventive
Fungicidal preparation applied during leather finishing to prevent mold growth in humid storage. HTS 3809.93.5000 for leather industry biocides as finishing agents. Critical for exported leathers.
Setting Agent for Leather Embossing
Thermoplastic resin emulsion that temporarily plasticizes leather for deep grain embossing then sets permanently. Fits HTS 3809.93.5000 as leather finishing preparation. Used for corrected grain leathers.
