Last updated: April 2026 dataThe catch-all fertilizer heading 310590 captures mineral or chemical fertilizers not classified elsewhere in Chapter 31, including the distinct tariff line for potassium nitrate–sodium nitrate mixtures (3105900010) alongside a broader residual line (3105900050). Russia leads US imports under this heading, with Canada and Chile also significant sources, reflecting global potassium and specialty nutrient trade flows. The heading's breadth means classification disputes are common — importers must confirm that a product's nutrient profile does not place it in a more specific Chapter 31 heading before defaulting to NESOI.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Tariff line 3105900010 specifically covers fertilizers composed of a potassium nitrate and sodium nitrate mixture. Products that do not meet that specific composition — but still fall outside all other named Chapter 31 headings — are classified under 3105900050. The distinction matters because duty rates and any applicable trade-remedy exposure can differ between the two lines.
Russia's dominance reflects its large-scale production of specialty and compound fertilizers not covered by more specific headings. This concentration creates exposure to sanctions-related trade disruptions and freight volatility. Importers relying heavily on Russian supply should monitor export-control developments and consider contingency sourcing from Canada or Chile.
