Product classification
HS code for Manure: 3101.00
Fertilizers, animal or vegetable, whether or not mixed together or chemically treated, fertilizers, produced by the mixing or chemical treatment of animal or vegetable products.
Classification of manure under HS 3101.00
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.

Codes often confused with 3101.00
Common mistake. 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.

In 2025, the largest exporter of HS 310100 (the code used for manure) in UN Comtrade data was the Netherlands, with 20% of world exports; the largest importer in UN Comtrade data was France, with 8.5% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 1.7% of its imports here ($1.7M, CEPII BACI), so it may also belong among the top importers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
