HS-4 · Heading
2819 — Chromium oxides and hydroxides
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2819 when importing or exporting chromium oxides and hydroxides, such as chromium trioxide used in metal finishing processes. This heading covers products that are crucial in various applications, including pigments and catalysts.
When deciding between HS-6 281910 and HS-6 281990, note that 281910 specifically refers to chromium trioxide, a highly regulated substance due to its hazardous nature. In contrast, 281990 encompasses other chromium oxides and hydroxides that do not include chromium trioxide, making it essential to identify your product accurately.
If you're dealing with chromium compounds, ensure you distinguish between the two subheadings based on the specific chemical composition. For example, if your shipment includes a mixture of chromium oxides but not chromium trioxide, you would classify it under 281990.
