U.S. exports of animal or vegetable fertilizers (HS 310100) totaled $3.3M in August 2026.
Importers of Animal or Vegetable Fertilizers paid $124K in duties in August 2026, an effective tariff rate of 4.76% of the $2.6M imported — duty actually collected as a share of that value, not the published tariff schedule. Animal or Vegetable Fertilizers imports of $2.6M in August 2026 ran 50% below the year-to-date monthly average of $5.2M.
Last updated: August 2026 dataOrganic fertilizers derived from animal or vegetable matter — including manure, compost, guano, and processed plant-based amendments — whether or not mixed or chemically treated, serve as a primary input for sustainable and organic agriculture. Canada, France, and Mexico are the leading suppliers to the US market, a pattern consistent with proximity-driven bulk commodity trade and established agricultural trade relationships. The single 10-digit line (3101000000) covers the full range of these organic fertilizer types, so classification turns on confirming that the product has not been processed to the point of becoming a chemically defined compound (which would shift it to Chapter 31's mineral fertilizer headings). EPA may have jurisdiction over certain treated or blended products under pesticide or soil amendment regulations, and USDA APHIS may require phytosanitary documentation for plant-based materials.

Heading 3101 covers animal or vegetable fertilizers in their natural, mixed, or lightly chemically treated forms. Once a product is processed into a chemically defined compound — such as ammonium nitrate or superphosphate — it shifts to the specific mineral or chemical fertilizer headings elsewhere in Chapter 31. The key test is whether the product retains its organic character or has been transformed into a distinct chemical substance. A licensed customs broker can advise on borderline cases.
Yes, in many cases. Plant-based organic materials such as composted plant matter or certain processed vegetable residues may require a phytosanitary certificate from the country of origin and are subject to USDA APHIS inspection at the port of entry to prevent the introduction of plant pests or diseases. The specific requirements depend on the material's origin, processing method, and whether it meets APHIS-approved treatment standards. Importers should consult APHIS import regulations and a licensed customs broker before shipment.
