Last updated: August 2026 dataDual-nutrient fertilizers combining phosphorus and potassium — but not nitrogen — fall here when not elsewhere specified in Chapter 31, classified under the single tariff line 3105600000. These blended products serve specialty crop and turf markets where nitrogen-free formulations are agronomically preferred. Israel leads US supply, followed by the Netherlands and Canada, reflecting both established chemical manufacturing capacity and proximity advantages. Importers should verify nutrient content declarations on commercial invoices, as misclassification between nitrogen-containing and nitrogen-free formulas is a common audit trigger.

Heading 3105.60 captures fertilizers containing both phosphorus and potassium but no nitrogen. If the product also contains nitrogen, it would fall under a different Chapter 31 heading (e.g., NPK fertilizers). The absence of nitrogen is the critical classification criterion, and nutrient content should be documented on the commercial invoice and certificate of analysis.
Imports from China may be subject to Section 301 tariffs. Importers sourcing from any supplier should confirm current tariff treatment with a licensed customs broker, as trade-remedy applicability depends on the country of origin and the specific product formulation.
