U.S. imports of fertilizers: double salts and mixtures of calcium nitrate and ammonium nitrate (SITC 56214) totaled $8.1M in April 2026, traded with 14 countries.
Importers of Fertilizers: Double Salts and Mixtures of Calcium Nitrate and Ammonium Nitrate paid $15K in duties in April 2026 — an effective duty rate of 20% on $77K in dutiable value, based on actual customs collections rather than the published tariff schedule. Fertilizers: Double Salts and Mixtures of Calcium Nitrate and Ammonium Nitrate imports of $8.1M in April 2026 ran 25% above the year-to-date monthly average of $6.5M.
Last updated: April 2026 dataCalcium ammonium nitrate (CAN) blends combine the rapid nitrogen availability of ammonium nitrate with the calcium nutrition and soil-pH buffering provided by calcium nitrate, making them a preferred straight fertilizer for vegetable production, orchards, and high-value horticulture. The calcium content distinguishes CAN from straight ammonium nitrate for both agronomic and regulatory purposes, and the lower ammonium nitrate concentration in many CAN grades places them below certain explosive-precursor thresholds, though importers should verify applicable DHS and EPA thresholds for their specific product grade. Classification accuracy relative to straight ammonium nitrate headings is essential, as the two carry different duty and trade-remedy exposure.

CAN is classified as a double salt or mixture of calcium nitrate and ammonium nitrate rather than as a straight ammonium nitrate fertilizer. The key distinction is the presence of calcium nitrate as a co-constituent, which changes the chemical and regulatory profile. Importers should provide a certificate of analysis showing the calcium nitrate and ammonium nitrate percentages to support correct classification and to demonstrate whether the product falls within or outside the scope of any antidumping orders targeting straight ammonium nitrate.
Regulatory thresholds for CAN under frameworks such as CFATS depend on the ammonium nitrate concentration in the specific product grade. Many commercial CAN grades have lower ammonium nitrate content than straight AN, which may place them below certain reporting thresholds, but importers must confirm the applicable threshold for their exact product specification with CISA and EPA rather than assuming an exemption applies.
