What Are HS Codes for Non-Metallic Inorganic Oxides?
HS codes classify non-metallic inorganic oxides for international trade under the Harmonized System. Managed digit codes form the basis for tariffs worldwide.
- First two digits indicate the chapter (28 for inorganic chemicals).
- Next two specify the heading (e.g., 28.11 for oxygen compounds).
- Last two denote subheadings based on composition.
- Countries add digits for local tariffs (e.g., 10-digit US HTS).
- Essential for 2025 tariff compliance in e-commerce shipments.
Chapter 28: Non-Metallic Inorganic Oxides HS Codes 2025
Chapter 28 covers inorganic chemicals, with non-metallic inorganic oxides primarily in headings 28.11 to 28.23.
- 2811.21: Carbon dioxide – Used in beverages and fire extinguishers.
- 2811.22: Silicon dioxide (silica) – Key for glass and rubber production.
- 2811.29: Other non-metal oxygen compounds like phosphorus oxides.
- 2819.90: Chromium oxides excluding chromic acid – For chrome plating.
- 2821.10: Iron oxides and hydroxides – Common pigments.
- 2823.00: Titanium oxides – Widely used in paints and sunscreens.
These HS codes remain stable globally until the next WCO revision in 2027.
HS Code 2811.22: Silicon Dioxide Classification Guide
Silicon dioxide, or silica, falls under HS code 2811.22 for shipments in 2025.
- Confirm chemical formula SiO2 content above 99%.
- Classify by form: powder, granules, or lumps.
- Check purity for subheading accuracy.
- Include Safety Data Sheets (SDS) for customs.
- Verify regional extensions like GCC 12-digit HS codes.
LSI keywords: HS classification 2025, silicon dioxide tariff code.
HS Code for Titanium Oxides: 2823.00 Details
HS code 2823.00 applies to all titanium oxides, including rutile and anatase forms.
- Sulfate process vs chloride process affects purity but not the base code.
- Used in 90% of white pigments globally.
- 2025 EU updates refine subheadings for nanoparticle variants.
- US HTS requires 10-digit for de minimis imports post-August 2025.
- Avoid misclassification with metallic compounds in Chapter 81.
Iron Oxides HS Code 2821.10: Key Criteria
Iron oxides and hydroxides use HS code 2821.10, distinct from metallic iron.
- Fe2O3 content determines pigment quality.
- Earth colors (2821.20) require ≥70% iron oxide.
- Common in construction and ceramics.
- 2025 GCC shift to 12-digit codes demands precise declarations.
- Pair with test certificates for clearance.
How to Find HS Code for Non-Metallic Inorganic Oxides: Step-by-Step
Use this 2025 guide to accurately classify non-metallic inorganic oxides.
- Review product composition and SDS.
- Search WCO HS nomenclature online.
- Match to Chapter 28 headings.
- Add country-specific digits.
- Consult official tools or customs brokers.
Pro tip: National changes in 2025 emphasize e-commerce compliance.
2025 Regional HS Code Changes for Inorganic Oxides
While global HS codes are stable, 2025 brings regional updates for non-metallic inorganic oxides.
- US: Mandatory 10-digit HTS for all imports after de minimis threshold ends.
- GCC: 12-digit HS codes effective January 1 for precise tariffs.
- EU: Combined Nomenclature 2025 adds purity-based subheadings.
- China: Enhanced e-commerce HS verification rules.
- Global: No WCO changes until 2027, but monitor national portals.
Common Classification Challenges for Inorganic Oxides
Misclassifying non-metallic inorganic oxides leads to delays and penalties in 2025.
- Blends with organics may shift to Chapter 38.
- Purity thresholds alter subheadings.
- Nanomaterials face emerging scrutiny.
- Multi-country shipments need dual compliance.
- E-commerce low-value goods now fully regulated.
