Calcium Super Phosphate SSP 16%/18% Granular Fertilizer - Export Specification Check

Granular single super phosphate (SSP) fertilizer candidate with declared Total P2O5 18%, Available P2O5 16%, 2-4 mm granules, and 50 kg packing. This item should be evaluated as an agricultural fertilizer input, not as food-grade phosphate. Overseas buyers should verify CAS, fertilizer registration requirements, heavy metal limits, impurity profile, export documents, and destination-country import rules before RFQ confirmation.

Package and route

Packing notes

  • Declared packing: 50 kg bags
  • Confirm bag type, liner, moisture barrier, palletization, and container loading plan before order
  • Confirm whether supplier can provide export marks, batch number, net weight, origin, and destination-specific labeling
  • For bulk RFQs, request photos of actual packaging, pallet condition, and loading method
  • Clarify whether product is supplied in granular or powder form, as bulk density differs by form

Human review

Compliance notes

  • This listing appears to be for agricultural fertilizer SSP, not food phosphate. Do not source for food, feed, pharma, or food additive use unless supplier provides the correct grade and applicable certificates.
  • Verify fertilizer registration, import permit, and product labeling requirements in the destination country, including India if applicable.
  • Request current COA per batch and compare P2O5, moisture, free acid, granulation, and heavy metals against buyer specification.
  • Check heavy metal limits for Cd, Pb, Hg, fluoride, and other regulated impurities under destination fertilizer rules.
  • Confirm whether MSDS/SDS, COA, commercial invoice, packing list, certificate of origin, phytosanitary or fertilizer-related documents, and inspection certificates are available as required.
  • Confirm Dangerous Goods status for sea/air shipment with supplier SDS and freight forwarder; do not rely only on marketplace text.
  • HS code and customs classification must be validated by the importer or customs broker before shipment.
  • No regulatory approval, customs clearance, or compliance outcome should be assumed from supplier claims alone.

  • Is CAS 10031-30-8 used for the actual supplied product, and does the SDS match the batch and composition?
  • What standard is followed for SSP quality control, and can you provide third-party inspection results?
  • Can the product meet the buyer's destination-country fertilizer heavy metal limits, especially for India import requirements?
