HTS Code: 2819 — Chromium Oxides and Hydroxides

Heading 2819 encompasses chromium oxides and hydroxides, which are inorganic chemical compounds primarily used in industries such as metal finishing, pigments, and chemical manufacturing. These compounds vary in chemical composition but share chromium as their central element.

• Chromium trioxide (CrO₃): A highly oxidizing, bright red crystalline solid widely used in chrome plating and as an oxidizing agent.
• Other chromium oxides and hydroxides: Includes various chromium compounds that do not fall under chromium trioxide, such as chromium(III) oxide and chromium hydroxide, often used as pigments or intermediates in chemical processes.

Code Hierarchy

• Section VI:
• Products of the Chemical or Allied Industries (Chapters 28-38)
• Chapter 28: Inorganic Chemicals; Organic or Inorganic Compounds of Precious Metals, of Rare-Earth Metals, of Radioactive Elements or of Isotopes
• Heading 2819: Chromium oxides and hydroxides
• US HTS Code (10-digit): 2819.XX.XXXX – The last digits specify the exact chemical form.

Detailed Breakdown of Subheadings

The heading 2819 is subdivided into more precise categories based on the specific chemical compound:

What is NOT Classified Here?

To ensure accurate classification, the following should be noted as exclusions:

• Other chromium compounds such as chromium salts (e.g., chromium sulfate or chromium chloride) are classified under different headings in Chapter 28.
• Organic chromium compounds are excluded and fall under other chemical classifications.
• Chromium metal and alloys containing chromium are classified under Chapter 72 or 81 depending on the product.

Notes

• Industrial Use:
• Chromium trioxide is widely used for chrome plating and corrosion resistance treatments, requiring proper handling due to toxicity and environmental regulations.
• Trade Regulations: Certain chromium compounds classified under 2819 may be subject to environmental and safety regulations influencing import/export controls.
• Duty Rates: Duty and tariff rates depend on the precise HTS code and country of origin; consult current customs schedules for accurate rates.
