HTS US: 2813.XX.XXXX
Description
Heading 2813 encompasses a group of chemical compounds primarily composed of sulfides of nonmetals. These substances are widely used in various industrial applications including in the manufacture of chemicals, pesticides, and other specialized products. The key products under this heading include:
- Carbon disulfide (CS2): A volatile, colorless liquid with a distinct odor, extensively used as a solvent and in the production of viscose rayon and cellophane.
- Sulfides of arsenic: Compounds where arsenic is combined with sulfur, often utilized in the chemical industry.
- Sulfides of phosphorus including commercial phosphorus trisulfide (P2S3): Important in the manufacture of pesticides, lubricants, and flame retardants.
- Other sulfides of nonmetals: Various sulfide compounds not classified elsewhere within this heading.
These chemical substances are generally classified based on their elemental composition and commercial form.

- Chapter 28: Inorganic Chemicals; Organic or Inorganic Compounds of Precious Metals, of Rare-Earth Metals, of Radioactive Elements or of Isotopes
- Heading 2813: Sulfides of nonmetals; commercial phosphorus trisulfide
- US HTS Code (10-digit):
2813.XX.XXXX– Specific codes identify particular sulfides such as carbon disulfide, arsenic sulfides, and phosphorus sulfides.
Detailed Breakdown of Subheadings
The 4-digit HS heading 2813 is subdivided into more specific 6-digit and 10-digit codes that distinguish between different sulfides of nonmetals.
| HS/HTS Code | Description |
|---|---|
| 2813.10.00.00 | Carbon disulfide |
| 2813.90.10.00 | Sulfides of arsenic |
| 2813.90.20.00 | Sulfides of phosphorus (including commercial phosphorus trisulfide) |
| 2813.90.50.00 | Other sulfides of nonmetals |
What is NOT Classified Here?
To prevent misclassification, note that the following are excluded from this heading:
- Metal sulfides and sulfide ores, which are classified under different headings.
- Organic sulfur compounds not specifically sulfides of nonmetals.
- Prepared chemical products or mixtures where sulfides are part of a formulation but not the principal component.
Notes
- Commercial Importance: Carbon disulfide is a significant industrial chemical with uses in rayon production and as a solvent, while phosphorus trisulfide is critical in pesticide manufacture.
- Handling and Safety: These compounds often require careful handling due to toxicity and flammability risks.
- Import Regulations: Importers should ensure compliance with chemical safety regulations and proper documentation when shipping under these codes.
