283090
Sulphides and polysulphides; whether or not chemically defined, other than sulphides of sodium
Heading 2830 — Sulphides; polysulphides whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283090 when importing or exporting sulphides and polysulphides that are not sodium-based. For example, if you're shipping a batch of barium sulphide for use in pigments, this is the correct code.
This code specifically covers sulphides and polysulphides that are chemically defined but do not include sodium sulphides, which fall under a different classification. If you deal with ammonium or calcium sulphides, you’ll also use this code.
In contrast, HS-6 283010 covers sodium sulphides, which are used in various applications like paper production. If your products include sodium sulphide, ensure you classify them correctly to avoid customs issues.
When classifying your products, consider the chemical composition and intended use. If your shipment includes mixtures or compounds containing sulphides, you may need to provide additional documentation to clarify the classification.
