U.S. exports of Fertilizers, N.E.S. (SITC 56299) totaled $12.9M in August 2026.
Importers of Fertilizers, N.E.S. paid $56K in duties in August 2026, an average duty rate of 0.71% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Fertilizers, N.E.S. imports of $7.9M in August 2026 ran 29% below the year-to-date monthly average of $11.2M.
Last updated: August 2026 dataThe broadest residual fertilizer heading under SITC, 56299 captures fertilizer products that do not fit any of the more specific nitrogen, phosphorus, potassium, or combination headings — including certain micronutrient fertilizers, organic-mineral hybrids, and novel formulations entering the market. Classification here is strictly by exclusion, and the burden falls on the importer to demonstrate why the product does not belong in a more specific heading. As sustainable agriculture drives innovation in fertilizer chemistry, this heading increasingly sees novel slow-release, biostimulant-adjacent, and micronutrient products that lack a dedicated classification.

Products frequently classified here include micronutrient fertilizers (zinc, boron, manganese, etc.) not combined with primary macronutrients, certain organic-mineral hybrid fertilizers, humic and fulvic acid-based soil amendments marketed as fertilizers, and novel controlled-release formulations that do not fit the chemical definitions of the specific headings.
The recommended approach is to obtain a detailed certificate of analysis identifying all nutrient elements and their concentrations, then work through the SITC heading hierarchy systematically — checking each specific heading before defaulting to N.E.S. For products with genuinely ambiguous classification, a binding ruling request to CBP provides certainty and protects against post-entry reclassification. A licensed customs broker with agricultural chemical experience is well-positioned to guide this process.
