Products classified under HTS 3810.90.10.00
Aromatic-Enhanced Steel Pickling Solution
A liquid pickling preparation for cleaning steel surfaces prior to fabrication, containing over 5% aromatic hydrocarbons like benzene derivatives to enhance rust removal and surface activation. Classified under HTS 3810.90.10.00 due to its high aromatic content and use as a metal pickling agent for removing oxides. Meets the subheading criteria for preparations with significant aromatic substances.
Toluene-Based Aluminum Pickling Paste
Thick paste formulation with toluene (aromatic solvent) exceeding 5% by weight, used for pickling aluminum alloys to remove oxide layers before anodizing. Falls under 3810.90.10.00 as a metal surface pickling preparation with qualifying aromatic content.
Xylene Flux for Brazing Copper Pipes
Flux preparation containing xylene isomers (>5% aromatic content) for brazing copper plumbing pipes, preventing oxidation during high-heat joining. Classified in 3810.90.10.00 for auxiliary soldering/brazing preparations with aromatic substances.
Aromatic Welding Electrode Coating Powder
Powder used as coating for MIG welding electrodes, incorporating modified aromatic resins over 5% by weight for arc stability and slag formation control. HTS 3810.90.10.00 covers such auxiliary preparations for welding electrodes.
Benzene Derivative Soldering Paste for Electronics
High-aromatic soldering paste (>5% benzene-based modifiers) for surface-mount electronics assembly, providing flux action and solder alloy dispersion. Fits 3810.90.10.00 as auxiliary soldering preparation with aromatic content.
Modified Aromatic Metal Welding Flux Core
Flux core wire filler material with modified aromatic compounds (>5%) for flux-cored arc welding of structural steel. 3810.90.10.00 applies to such welding auxiliary preparations.
Styrene-Enhanced Brass Brazing Flux
Liquid flux for brazing brass fittings containing styrene derivatives (>5% aromatics) to improve wetting and capillary action. Classified under HTS 3810.90.10.00 for brazing auxiliaries.
Aromatic Pickling Inhibitor for Steel
Additive concentrate with aromatic amines (>5%) used in acid pickling baths to prevent hydrogen embrittlement on steel strip. 3810.90.10.00 for metal pickling preparations.
High-Aromatic Silver Solder Flux
Specialty flux for silver-based soldering of jewelry and instruments, containing >5% aromatic activators for superior cleanability. HTS 3810.90.10.00 classification.
