HS-4 · Heading
2814 — Ammonia; anhydrous or in aqueous solution
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2814 when importing or exporting ammonia, whether it's anhydrous or in aqueous solution. For example, a shipment of anhydrous ammonia in bulk containers for agricultural use falls under this heading. Knowing the correct subheading is crucial for accurate customs declarations and compliance.
When deciding between HS-6 281410 for anhydrous ammonia and HS-6 281420 for ammonia in aqueous solution, consider the physical state of your product. Anhydrous ammonia is a gas at room temperature, while aqueous ammonia is a solution in water, often used in cleaning products or fertilizers.
If your shipment consists of ammonia dissolved in water, you'll need to classify it under HS-6 281420. In contrast, if you're dealing with ammonia that has no water content, HS-6 281410 is the appropriate choice. Be mindful of the packaging and concentration, as these factors can influence the classification.
