Product classification
HS code for Organic fertilizer: 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 organic fertilizer under HS 3101.00
Organic fertilizers are classified under HS code 3101.00 because they consist of animal or vegetable products, whether or not mixed together or chemically treated. This classification is governed by Chapter 31 of the Harmonized System, which specifically addresses fertilizers. The primary criteria for classification under 3101.00 is the origin of the material; it must be derived from organic matter rather than synthetic chemical processes. Even if these products have been subjected to chemical treatment to enhance their nutrient profile or stability, they remain under this heading as long as the base material is of animal or vegetable origin. This includes products that have been dehydrated, composted, or mixed with other organic substances to create a balanced soil amendment. The classification ensures that natural soil enhancers are distinguished from purely mineral or chemical fertilizers found in subsequent headings of the same chapter.

Codes often confused with 3101.00
Common mistake. Organic fertilizers are frequently misclassified under HS code 3105, which covers mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. While organic fertilizers may contain these elements, 3105 is reserved for products where the primary fertilizing component is mineral-based or synthetic. Another common error is using HS code 0506 for bone meal; however, 0506 is for raw bones and horn-cores, whereas 3101.00 is used once the material is prepared as a fertilizer. Additionally, products intended for animal feed rather than soil enrichment should be classified under 2309.
Top exporters and importers of HS 310100 (the code used for organic fertilizer), 2025
In 2025, the largest exporter of HS 310100 (the code used for organic fertilizer) 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.
Figures cover everything classified under HS 310100, not only organic fertilizer.

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).
