HS-6 · Subheading
310520
Fertilizers, mineral or chemical; containing the three fertilizing elements nitrogen, phosphorus and potassium
Heading 3105 — Fertilizers; mineral or chemical, containing 2 or 3 of the elements nitrogen, phosphorus, potassium; other fertilisers; goods of chapter 31 in tablets or packages of gross weight not exceeding 10kg
Chapter 31: Fertilisers
Plain-language overview
Use HS-6 310520 when importing or exporting fertilizers that contain nitrogen, phosphorus, and potassium. An example would be a shipment of a granular fertilizer blend packaged in 5 kg bags, specifically designed for agricultural use.
This code is specific to fertilizers that include all three primary nutrients: nitrogen, phosphorus, and potassium. In contrast, HS-6 310510 covers fertilizers with only nitrogen and phosphorus, which may not provide the complete nutrient profile required for certain crops.
When classifying under this heading, it’s essential to ensure that the product indeed contains all three elements in measurable amounts. Products that are labeled as 'NPK fertilizers' typically fall under this category, while those with lesser nutrient combinations may require a different classification.
If you're dealing with packaged fertilizers weighing less than 10 kg, this code is particularly relevant. For larger quantities, you might need to look at other codes under the same heading that cater to bulk shipments.
