HS Code for Packaged fertilizer

Packaged fertilizer is classified under HS code 310510. This classification is governed by the legal notes of Chapter 31, which covers fertilizers. Heading 3105 applies to mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium, as well as other fertilizers. Crucially, subheading 310510 is a unique category based on the physical form and packaging of the product rather than just its chemical composition. It includes any fertilizer product, regardless of its chemical makeup (even if it would otherwise fall under 3102, 3103, or 3104), provided it is presented in tablets or similar forms or in packages with a gross weight not exceeding 10 kilograms. This rule is designed to distinguish retail-ready products intended for home gardening or small-scale use from bulk industrial or agricultural fertilizers. The classification under 310510 takes precedence over other subheadings in Chapter 31 when the weight or form criteria are met, following the specific instructions provided in Note 2 to Chapter 31.

Products Included

• NPK fertilizers in 5kg or 10kg retail bags
• Fertilizer tablets for houseplants
• Liquid fertilizers in small retail bottles (under 10kg)
• Ammonium sulfate packaged for retail sale (under 10kg)
• Urea pellets in small consumer-grade containers

Common Misclassification

The most common misclassification occurs when importers use the chemical-specific codes such as 310210 (Urea), 310420 (Potassium chloride), or 310520 (NPK fertilizers) for small packages. While these codes describe the chemical content, the packaging rule for 310510 is a "super-rule" that overrides the chemical classification if the gross weight is 10kg or less. Another error involves confusing organic fertilizers (Chapter 3101) with mineral fertilizers; however, if an organic fertilizer is processed into tablets or small packages, it may still be scrutinized under the 310510 criteria depending on its mineral additives.
