Triple Superphosphate 46% P2O5 Fertilizer
Triple superphosphate (TSP) is a high-phosphorus fertilizer containing 46% P2O5 by weight, produced by reacting phosphate rock with phosphoric acid. It falls under HTS 3103.11.00.00 as a superphosphate with 35% or more diphosphorus pentaoxide, specifically the triple grade variant. Used primarily for root development in crops like corn and soybeans.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If P2O5 content is under 35% by weight
Superphosphates with less than 35% P2O5 fall under the lower concentration subheading within the same phosphatic fertilizers heading.
If put up in retail packaging like consumer bags under 10kg
Fertilizers packaged in forms or packages for retail sale are excluded from heading 3103 and classified under 3105.
If blended with potassic fertilizers like potassium chloride
Mixtures of phosphatic and potassic fertilizers are classified under heading 3104 as compound fertilizers.

Import Tips & Compliance
• Verify P2O5 content through lab analysis to confirm classification under 3103.11.00.00 (≥35%) vs lower grades in 3103.10
• Obtain fertilizer registration certificates from USDA/APHIS and ensure proper labeling of nutrient content per EPA FIFRA regulations
• Avoid common pitfalls like misdeclaring as blended fertilizer, which could shift to 3105 if packaged for retail
