Last updated: August 2026 dataNitrogenous fertilizers not elsewhere specified under Chapter 31 — including products such as calcium cyanamide, certain slow-release nitrogen formulations, and other nitrogen compounds used as fertilizers — are captured under 3102900100. Canada, Russia, and the Netherlands are the leading US suppliers of this residual category, which serves as a catch-all for nitrogen fertilizer products that do not fit the more specifically defined headings. Because the category is heterogeneous, classification disputes can arise when a product's nitrogen compound type or mixture composition places it at the boundary with headings 3102210000–3102800000; a binding ruling request may be warranted for novel formulations.

Products classified here include calcium cyanamide, certain polymer-coated or slow-release nitrogen fertilizers, and nitrogen compounds used as fertilizers that do not match the specific chemical descriptions of headings 310221 through 310280. Novel biostimulant-nitrogen blends and industrial-grade nitrogen compounds repurposed as fertilizers may also land here, though each requires individual classification analysis.
A binding ruling is advisable when a product's chemical composition or intended use places it at the boundary between two or more headings — for example, a slow-release urea-formaldehyde condensate that could be argued under either heading 3102 or heading 3105. Filing a ruling request before the first shipment provides classification certainty and protects against retroactive duty assessments.
