HS Code for Hydroxide: 2025 Complete Guide
TL;DR: Key Hydroxide HS Code Takeaways for 2025
- **HS codes for hydroxide primarily fall under Chapter 28, with codes like 2815 for sodium hydroxide.**
- 2025 updates include GCC 12-digit extensions and EU nomenclature changes for precise classification.
- Correct HS code usage prevents duties errors, delays, and compliance issues in global trade.
- Verify country-specific tariff schedules for accurate hydroxide import/export classification.
- Shipping hydroxides requires hazmat compliance alongside proper HS code declaration.
What Is the HS Code for Hydroxide? Core Classification Rules
The HS code for hydroxide starts with Chapter 28 for inorganic chemicals in the 2025 Harmonized System.
Hydroxides are bases used in industry, classified digit standard, but nations add digits for tariffs.
In 2025, no WCO overhaul occurred—next revision is 2027—but national changes demand vigilance for hydroxide shipments.
Primary HS Codes for Hydroxide: 2025 Updated List
Specific HS codes for hydroxide depend on the compound type, all under Chapter 28 in 2025.
| Hydroxide Type | HS Code 2025 | Common Use |
|---|
| Sodium hydroxide (caustic soda) | 2815.11 | Water treatment, soap |
| Potassium hydroxide (caustic potash) | 2815.20 | Batteries, fertilizers |
| Magnesium hydroxide | 2816.10 | Antacids, flame retardants |
| Aluminum hydroxide | 2818.30 | Pharmaceuticals, fillers |
| Calcium hydroxide | 2825.90 | Construction, water softening |
These HS codes for hydroxide ensure uniform global identification. Always check subheadings for purity or form (solid/liquid).
How to Find the Correct HS Code for Hydroxide Shipments
Finding the HS code for hydroxide involves matching your product specs to the tariff schedule step-by-step.
- Identify the chemical formula and purity level.
- Locate Chapter 28, heading 2815-2825.
- Select subheading based on metal (e.g., 2815.11 for NaOH solid).
- Confirm with national extensions like US HTS or EU TARIC.
- Use WCO tools or official databases for 2025 verification.
This how-to process minimizes errors in hydroxide classification for customs.
2025 HS Code Changes Impacting Hydroxide Classification
Key 2025 HS code updates refine hydroxide subcategories without WCO core changes.
- GCC nations adopt 12-digit HS codes effective Jan 1, 2025, adding specificity for hydroxide peroxides.
- EU Combined Nomenclature (CN) updates 2815-2825 for environmental compliance tracking.
- US HTS mandates for postal shipments from Sep 2025 affect small hydroxide parcels.
- China and India refine hydroxide codes for green chemistry imports.
- Australia updates for mining-related magnesium hydroxide under 2816.
These shifts highlight why monitoring regional HS code for hydroxide is essential for trade.
Common Mistakes with HS Code for Hydroxide and How to Avoid Them
Errors in HS code for hydroxide lead to penalties, seizures, and extra costs in 2025.
- Misclassifying sodium hydroxide solution as solid (use 2815.12 vs 2815.11).
- Ignoring country-specific digits beyond WCO six-digit code.
- Confusing hydroxide with oxide (e.g., 2815 vs 2826).
- Overlooking purity thresholds affecting subheadings.
- Failing to update for 2025 national tariff revisions.
Audit shipments annually and consult official sources to sidestep these pitfalls.
HS Code for Hydroxide in Global Trade: Country-Specific Examples
HS code for hydroxide varies by country extensions in 2025, demanding localized checks.
| Country/Region | Sodium Hydroxide HS Code | Key 2025 Note |
|---|
| USA (HTS) | 2815.11.0000 | Postal enforcement Sep 2025 |
| EU (CN) | 2815 11 00 | REACH-aligned updates |
| GCC | 2815.11.00.00 | New 12-digit system |
| China | 28151100 | Green import priorities |
| Australia | 2815.11.00 | Mining sector focus |
Tailor your HS code for hydroxide to destination rules for seamless clearance.
Shipping Hydroxides: Hazmat Rules Alongside HS Code Compliance
Hazards of hydroxide shipments require UN numbers plus accurate HS code in 2025.
- Sodium hydroxide: UN 1824, Corrosive class 8.
- Potassium hydroxide: UN 1813, same class.
- Packaging: IBCs or drums with liners for liquids.
- Labels: Corrosive pictogram mandatory.
- Segregation: Away from acids in containers.
Pair HS code declaration with IMDG/IATA compliance for safe hydroxide transport.
