Double salts and blended mixtures of ammonium sulfate and ammonium nitrate occupy a distinct classification niche from either straight ammonium nitrate or straight ammonium sulfate, because the combined nitrogen-sulfur nutrient profile targets crops with elevated sulfur demand such as canola, alfalfa, and small grains. The classification boundary between this heading and adjacent nitrogenous fertilizer categories turns on the specific salt chemistry and blend ratios, making laboratory analysis or supplier certification useful documentation at entry. Importers should also confirm whether any active antidumping or countervailing duty orders on ammonium nitrate-containing products extend to these mixtures, as scope rulings can be product-specific.

Classification hinges on the chemical composition and the ratio of ammonium sulfate to ammonium nitrate in the blend. CBP may request a certificate of analysis or manufacturer's specification sheet confirming the product meets the double-salt or mixture definition. If the ammonium nitrate content dominates and the product does not qualify as a true double salt, it could be reclassified under the straight ammonium nitrate heading.
These blends are commercially attractive for sulfur-deficient soils common in the Pacific Northwest and parts of the Midwest, where crops like winter wheat, canola, and corn benefit from simultaneous nitrogen and sulfur delivery. Demand tends to track planting-season timing, so import volumes often concentrate in late winter and early spring.
