Metal Pickling Solution for Steel
A hydrochloric acid-based solution designed to remove rust and scale from steel surfaces prior to further processing. It falls under HTS 3810.90.5000 as a pickling preparation specifically for metal surfaces, used in industrial metal cleaning applications. This category covers auxiliary preparations essential for metal preparation in manufacturing.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as pure sulfuric or hydrochloric acid without metal-specific inhibitors
Pure acids without formulation for pickling fall under inorganic acids in Chapter 28, not prepared metal treatments.
If for industrial chemical mixtures not specifically for metal pickling
General chemical preparations lacking specific metal surface application shift to Chapter 38 other mixtures.
If imported as part of filtering or parts-washing equipment
If bundled with machinery as a component, it may classify under filtering/purifying equipment rather than standalone prep.

Import Tips & Compliance
• Classify as hazardous material (UN 1789) and provide Safety Data Sheets (SDS) compliant with OSHA and EPA standards
• Verify pH levels and inhibitor content to confirm classification as pickling prep, avoiding reclassification as general acids
• Include end-use certificates if for specific metal types to prevent scrutiny under anti-dumping duties
