Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 285390 when importing or exporting phosphides that are not ferrophosphorus, as well as other inorganic compounds not elsewhere classified. For example, this code applies to shipments of phosphides used in agriculture or chemical manufacturing.
This HS-6 line covers a variety of inorganic compounds, including distilled water and liquid air, which can be crucial for specific industrial applications. It differs from HS-6 285391, which specifically addresses ferrophosphorus compounds, so ensure you classify correctly based on the chemical composition.
When dealing with phosphides, it's important to note their applications, such as in fertilizers or as chemical intermediates. If your product is a phosphide that does not fall under ferrophosphorus, this is the appropriate code.
Additionally, this category includes other inorganic compounds like conductivity water, which is essential for electronics manufacturing. If you are unsure whether your product qualifies, consider consulting with a customs broker for clarity.
