HS Code for Manure

Manure and organic fertilizers are classified under HS code 3101.00 because they consist of animal or vegetable products that have been processed or mixed for use as soil nutrients. This code encompasses natural fertilizers that may be in their raw state, dehydrated, or chemically treated to enhance their effectiveness or stability. The classification logic rests on the origin of the material; if the fertilizer is derived from organic matter rather than synthetic chemical synthesis, it falls under Chapter 3101. This includes animal excreta (manure), composted vegetable matter, and products resulting from the chemical treatment of these organic bases. The code specifically excludes pure chemical fertilizers, which are classified in subsequent headings of Chapter 31 based on their nitrogen, phosphorus, or potassium content. The inclusion of "chemically treated" in the description allows for organic fertilizers that have been stabilized or enriched, provided the base remains animal or vegetable in nature.

Products Included

• Animal manure (dried or liquid)
• Guano (not chemically treated)
• Composted vegetable waste
• Mixed animal and vegetable fertilizers
• Dehydrated poultry litter

Common Misclassification

Manure is often misclassified under 3102, 3103, 3104, or 3105, which are reserved for mineral or chemical fertilizers. If a product is purely synthetic or mineral-based, it cannot fall under 3101.00. Additionally, raw animal products not intended for use as fertilizer might be confused with 0511.99, but if the intent is soil enrichment, 3101.00 is the correct heading.
