Chapter 28: Inorganic chemicals

Plain-language overview

Use HS-6 283329 when importing or exporting inorganic sulfates that aren’t classified elsewhere. For example, if you're shipping a bulk order of ammonium sulfate for agricultural use, this code would apply.

This code specifically covers sulfates not elsewhere classified (n.e.c.) in the heading. It differs from HS-6 283321, which is for sodium sulfate, and HS-6 283326, which pertains to magnesium sulfate, highlighting the need for precise classification.

When dealing with chemical compounds, it’s crucial to identify whether your product fits under this HS-6 line. If your shipment includes a unique sulfate compound not listed in other subheadings, you will likely use 283329.

Be aware that proper classification can affect tariffs and regulations. If you’re unsure, consulting with a customs broker can clarify whether your product fits this category.
