HS Code for Chromium Trioxide: 2819.10 (2025 Guide)

TL;DR: The HS code for Chromium trioxide remains 2819.10 in 2025, with no WCO changes until 2027 but key regional updates like GCC 12-digit codes and US de minimis end. This guide covers classification, tariffs, shipping rules, and compliance tips for accurate international trade.

What is the HS Code for Chromium Trioxide?

The HS code for Chromium trioxide is 2819.10, a stable classification in the 2025 HS codes guide for global trade.

• Defines Chromium trioxide (CrO3) as an inorganic chemical oxidizer
• Used in leather tanning, chrome plating, and pigments
• Hazard Class 5.1 (oxidizer) and 6.1 (toxic inhalation)
• Essential for customs declarations worldwide

HS Code Breakdown: Chromium Trioxide 2819.10 Structure

Chromium trioxide falls under Chapter 28 of the HS system. Here's the precise hierarchy for 2025 compliance.

1. Chapter 28: Inorganic chemicals; organic/inorganic compounds
2. Heading 2819: Chromium oxides and hydroxides
3. Subheading 2819.10: Specifically Chromium trioxide
4. National extensions like 2819.10.0000 for US HTS or GCC

Dark-red crystalline powder, highly soluble in water—key for accurate HS code for Chromium trioxide identification.

2025 HS Code Changes Affecting Chromium Trioxide

While WCO HS remains unchanged until 2027, 2025 brings regional shifts. Focus on these for tariff compliance.

• GCC (Saudi Arabia, UAE, etc.): 12-digit HS codes mandatory from January 1, 2025
• US: End of de minimis threshold August 29, 2025—full HTS required
• EU: Combined Nomenclature updates refine Chapter 28 chemicals
• Global surge in battery/electronics shipments pressures oxidizer logistics

How to Find and Verify HS Code for Chromium Trioxide (Step-by-Step)

Use this 2025 how-to guide for precise classification. Avoid fines with systematic checks.

1. Review product specs: Confirm CrO3 chemical composition
2. Search WCO database: Enter 'Chromium trioxide' for 2819.10
3. Check national extensions: US HTS, EU TARIC, GCC systems
4. Validate hazards: IMDG/ IATA for dangerous goods alignment
5. Consult official tools or experts for edge cases

Common Mistakes with Chromium Trioxide HS Code 2819.10

Misclassification of Chromium trioxide leads to delays and penalties in 2025.

• Confusing with 2819.90 (other chromium oxides)—fines up to $5K in GCC case study
• Ignoring regional digits: e.g., shipping 6-digit to 12-digit zones
• Overlooking hazardous flags post-US de minimis changes
• Failing purity tests: Impure CrO3 may shift subheadings

Tariffs and Duties for HS 2819.10 Chromium Trioxide in 2025

Tariff rates vary by origin and destination under 2025 HS codes. Plan accordingly.

Shipping Chromium Trioxide: Dangerous Goods Rules 2025

HS code for Chromium trioxide shipments demand special handling as UN 1463.

• IMDG packing group II; limited quantities allowed
• Required docs: DGD, SDS, HS declaration
• Carrier restrictions: No air for large volumes
• 2025 up
