HS Code for Sodium Hydroxide Aqueous Solution 2025
**TL;DR:** The HS code for sodium hydroxide aqueous solution remains
2815.12 in 2025. This guide covers classification, properties, 2025 regional updates, shipping rules, applications, and compliance tips for importers worldwide.
The HS code for sodium hydroxide aqueous solution ensures tariff compliance and seamless customs clearance in 2025 chemical shipments. Proper use of 2815.12 avoids delays, penalties, and unexpected duties across global trade routes.
What is the HS Code for Sodium Hydroxide Aqueous Solution?
The global HS code for sodium hydroxide aqueous solution is 2815.12, covering liquid caustic soda or soda lye forms.
- Chapter 28: Inorganic chemicals and compounds of precious metals
- Heading 2815: Sodium hydroxide (caustic soda) and potassium hydroxide
- Subheading 2815.12: Specifically for aqueous solutions (not solid flakes)
- Key distinction: Excludes solid sodium hydroxide under 2815.11
- Global standard: 6-digit WCO base code for international harmony
Countries extend this with 2-4 additional digits for local duties, stats, and regulations. Always verify via official tariff schedules.
Properties of Sodium Hydroxide Aqueous Solution (HS 2815.12)
Sodium hydroxide aqueous solution under HS 2815.12 is a highly corrosive liquid used in diverse industries.
- Typical concentration: 30-50% NaOH in water
- Physical state: Clear, colorless, viscous liquid
- pH level: Approximately 14 (strongly alkaline)
- Chemical formula: NaOH (aq)
- Common synonyms: Liquid caustic soda, soda lye, lye solution
These properties dictate its hazardous classification and packaging needs during transport.
Key Uses and Applications of HS 2815.12
HS 2815.12 sodium hydroxide aqueous solution powers essential industrial processes worldwide.
- Water treatment: pH adjustment and heavy metal precipitation
- Soap and detergent production: Saponification of fats and oils
- Food industry: Processing olives, pretzels (GRAS approved by FDA)
- Pulp and paper: Delignification and bleaching
- Petroleum: Acid neutralization in refining
Accurate HS classification supports duty-free imports under certain FTAs for these applications.

How to Verify HS Code 2815.12 for Your Shipment
Follow this step-by-step guide to confirm the HS code for sodium hydroxide aqueous solution in 2025.
- Examine product: Verify it's aqueous (liquid), not solid NaOH
- Access WCO HS: Locate Chapter 28, Heading 2815
- Select subheading: 2815.12 for solutions/soda lye
- Check concentration: All aqueous forms qualify
- Add national digits: Consult country-specific tariff database
- Cross-check hazards: UN 1824 Class 8 for transport docs
This process minimizes misclassification risks.
