HTS US: 2842.XX.XXXX
Description
This heading encompasses various other salts derived from inorganic acids or peroxoacids excluding azides. It notably includes double or complex silicates and aluminosilicates regardless of whether their chemical structure is precisely defined. Furthermore, it covers a range of other salts such as fulminates, cyanates, thiocyanates, selenides, and tellurides.
The materials classified under this heading are primarily industrial chemicals with applications in fields such as catalysis, pigments, electronics, and materials science. The category distinguishes between complex silicate compounds and other miscellaneous salts based on their chemical composition and structure.
Code Hierarchy
- Section VI:
- Chemical Products (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 2842: Other salts of inorganic acids or peroxoacids (including aluminosilicates whether or not chemically defined), other than azides.
- US HTS Code (10-digit):
2842.XX.XXXX– The last digits specify the exact type of salt or compound.
Detailed Breakdown of Subheadings
The 4-digit HS heading 2842 is subdivided into more specific categories based on the chemical nature and composition of the salts and compounds.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2842.10.00.00 | Double or complex silicates, including aluminosilicates whether or not chemically defined | Includes synthetic or natural complex silicate minerals and aluminosilicates used in various industrial applications such as ceramics, catalysts, and adsorbents. |
| 2842.90 | Other: | Miscellaneous salts not classified under silicates. |
| 2842.90.10.00 | Fulminates, cyanates and thiocyanates | Highly reactive salts with uses in explosives, chemical synthesis, and analytical chemistry. |
| 2842.90.90 | Other | Catch-all category for other salts not specified elsewhere. |
| 2842.90.90.10 | Selenides and tellurides | Compounds containing selenium or tellurium combined with other elements, used in semiconductors, glass manufacturing, and metallurgy. |
| 2842.90.90.50 | Other | Additional salts within this heading not further classified. |
What is NOT Classified Here?
For clarity and proper classification, note the following exclusions:
- Azides: These are explicitly excluded from heading 2842 and classified separately due to their distinct chemical properties and hazards.
- Simple inorganic salts: Basic salts of inorganic acids such as chlorides, nitrates, and sulfates are classified under different headings.
- Organic salts: This heading excludes organic salts which are classified in chapters dedicated to organic chemicals.
Notes
- Industrial Use: Many compounds under this heading are critical in manufacturing processes, chemical synthesis, and high-tech applications.
- Hazard Considerations: Certain compounds such as fulminates are sensitive and hazardous, requiring careful handling and regulatory compliance.
- Tariff Rates: Duty rates for these chemicals vary widely depending on the subcategory and intended use, often subject to strict import controls.
