HTS US: 2830.XX.XXXX
Description
The HTS code 2830 encompasses a group of chemical compounds known as sulfides and polysulfides. These substances are characterized by the presence of sulfur combined with metals or nonmetals, and may or may not be chemically defined in precise molecular terms. They are used extensively in industrial processes, pigments, luminescent materials, and chemical manufacturing.
The primary compounds covered under this heading include:
- Sodium sulfides: Compounds containing sodium and sulfur, commonly utilized in the pulp and paper industry, water treatment, and as reagents in chemical synthesis.
- Zinc sulfide: Available in various grades, including a luminescent grade with extremely high purity (99.99% or greater by weight), used in optical applications, phosphors, and pigments.
- Cadmium sulfide: A notable pigment and semiconductor material, primarily used in paints, plastics, and electronic devices.
- Other sulfides and polysulfides: This includes various other chemical forms not specifically detailed but falling under the broader classification.
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 2830: Sulfides; polysulfides, whether or not chemically defined
- US HTS Code (10-digit):
2830.XX.XX.XX– The additional digits specify the exact type and purity of the sulfide.
Detailed Breakdown of Subheadings
The 6-digit HTS heading 2830 is further divided into specific 8- and 10-digit codes to classify individual sulfide compounds based on their chemical composition and purity.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2830.10.00.00 | Sodium sulfides | Commonly used in industrial applications including water treatment and chemical synthesis. |
| 2830.90 | Other sulfides and polysulfides | Includes zinc sulfides, cadmium sulfides, and miscellaneous sulfides. |
| 2830.90.10.00 | Zinc sulfide, luminescent grade having a purity of 99.99 percent or more by weight | High-purity luminescent zinc sulfide for optical and phosphorescent applications. |
| 2830.90.15.00 | Other zinc sulfide | Lower purity or non-luminescent grades of zinc sulfide used in pigments and plastics. |
| 2830.90.20.00 | Cadmium sulfide | Used as a pigment and semiconductor material in various industrial sectors. |
| 2830.90.90.00 | Other | Any other sulfides or polysulfides not specified above. |
What is NOT Classified Here?
To ensure precise classification, the following are typically excluded from this heading:
- Organic sulfides: Compounds where sulfide groups are bonded within organic molecules usually fall under other chemical chapters.
- Non-sulfide sulfur compounds: Such as sulfates, sulfites, and elemental sulfur, which are classified elsewhere.
- Mixtures and preparations: Unless predominantly sulfides, mixtures with other compounds are usually classified under different headings.
Notes
- Purity and Grade Importance: The classification may depend heavily on the purity and chemical definition of the sulfide, especially for zinc sulfide luminescent grades.
- Industrial Usage: These compounds have widespread industrial uses ranging from pigments, semiconductors, to chemical intermediates, influencing their trade and regulation.
- Duty Rates: Import duty rates vary by exact subheading and purity; checking current USHTS for applicable tariffs is recommended.
