HTS US: 2843.XX.XXXX
Description
This heading encompasses various forms of precious metals in colloidal form as well as their inorganic or organic compounds. It also includes amalgams, which are alloys of precious metals with mercury. These materials are important in multiple industrial, chemical, and technological applications due to their unique chemical and physical properties. The classification covers both chemically well-defined compounds and those not chemically defined.
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
- Heading 2843: Colloidal precious metals; inorganic or organic compounds of precious metals, whether or not chemically defined; amalgams of precious metals.
- US HTS Code (10-digit):
2843.XX.XXXX– The final digits specify the exact type of compound or form.
Detailed Breakdown of Subheadings
The 4-digit HTS heading 2843 is further segmented into specific 6-digit and 10-digit codes that identify the precise nature of the precious metal compounds or amalgams.
| HTS Code | Description | Examples & Notes |
|---|---|---|
| 2843.10.00.00 | Colloidal precious metals | Suspensions of precious metals such as gold, silver, or platinum in colloidal form, typically used in catalysis, medicine, or electronics. |
| 2843.21.00.00 | Silver nitrate | A well-defined inorganic compound of silver widely used in photography, antiseptics, and chemical synthesis. |
| 2843.29.01.00 | Other silver compounds | Includes silver salts and other silver-based compounds not classified as silver nitrate. |
| 2843.30.00.00 | Gold compounds | Various inorganic or organic compounds containing gold, used in electronics, catalysis, and medicine. |
| 2843.90.00.00 | Other compounds; amalgams | Compounds of other precious metals like platinum, palladium, and their amalgams with mercury, used in dentistry, electronics, and chemical processes. |
What is NOT Classified Here?
To prevent misclassification, the following are excluded from this heading:
- Precious metals in metallic form or uncombined state – These are classified under different headings for metals and metal ores.
- Organic compounds not containing precious metals – These fall under organic chemical classifications.
- Non-precious metal compounds or amalgams – Covered under other chemical chapters.
Notes
- Industrial Applications: Colloidal precious metals and their compounds are widely used in catalysis, electronics, medical devices, and photographic industries, necessitating precise classification for trade and regulatory compliance.
- Chemical Definition: Some compounds are chemically defined (e.g., silver nitrate), while others may be mixtures or complex compounds, still falling under this heading.
- Amalgams: Amalgams, particularly those of silver and other precious metals with mercury, are included and are often used in dental applications.
