HS-4 · Heading
2834 — Nitrites; nitrates
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2834 when importing nitrites and nitrates, such as sodium nitrite used in food preservation or fertilizers. Understanding the specific type of nitrate or nitrite is crucial for proper classification.
When deciding between HS-6 283410 for nitrites and HS-6 283421 for potassium nitrates, consider the chemical composition and intended use. Potassium nitrates are often used in fertilizers, while nitrites may be found in food processing.
If your product is a nitrate but not potassium-based, you'll need to classify it under HS-6 283429. This includes various nitrates used in agriculture or industrial applications, so ensure you check the specific formulation.
