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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily sodium hydroxide-based
High-purity caustic soda solutions for pickling fall under inorganic chemicals in Chapter 28, not auxiliary preparations.
If for industrial chemical mixtures without specific metal prep function
General chemical preparations lacking pickling designation shift to catch-all chemical mixtures.
If formulated as surface active cleaning preparation
Preparations primarily functioning as detergents or cleaners are classified under Chapter 34.

Import Tips & Compliance
• Verify aromatic content via lab analysis to confirm HTS classification; obtain SDS and ensure HAZMAT shipping compliance
• Common pitfall: mislabeling as general cleaner leads to reclassification
