Calcium Super Phosphate SSP 16%/18% Granular Fertilizer - CAS 10031-30-8 Spec 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 listing appears to be fertilizer-grade material, not food-grade phosphate, and should be screened carefully for intended use, heavy metals, free acid, moisture, HS code, and export documentation before RFQ.

Use context

Common applications

  • Raw material for fertilizer blending where SSP grade is accepted
  • Direct granular phosphate fertilizer distribution subject to local fertilizer registration and import rules
  • Agricultural phosphorus, calcium, and sulfur nutrient supply programs
  • Bulk tender sourcing for SSP 16% available P2O5 after lab verification
  • Replacement or comparison quote against other SSP, TSP, DAP, or NPK fertilizer inputs
How we compare

Sourcing options

  • Request firm quotation for SSP granular 16% available P2O5 / 18% total P2O5 in 50 kg bags
  • Request alternative quotes for powder vs granular SSP if available
  • Request heavy-metal-controlled SSP specification for destinations with stricter fertilizer limits
  • Request third-party pre-shipment inspection and sealed samples from loaded batch
  • Request India documentation support package, including COA, SDS, COO, invoice, packing list, and HS code confirmation
  • If the buyer needs food phosphate for India, source a separate food-grade phosphate supplier instead of using this fertilizer-grade SSP listing
Human review

Compliance notes

  • This product should be treated as fertilizer-grade SSP, not food-grade phosphate
  • Do not use this candidate for food, feed, pharma, or food-additive sourcing unless the supplier provides appropriate grade-specific certification and regulatory documentation from qualified authorities
  • Verify CAS, EINECS, HS code, chemical identity, and grade on COA, SDS, commercial invoice, packing list, and customs documents
  • Heavy metal values are listed, including Cd, Pb, and Hg; buyer should compare against destination-country fertilizer limits and internal procurement limits
  • For India-focused sourcing, confirm Fertilizer Control Order or other applicable import requirements with a licensed local importer or regulatory consultant
  • Request recent batch COA, SDS in GHS format, TDS/specification sheet, certificate of origin, and third-party inspection option before placing a trial order
  • Confirm dangerous goods status, UN number if any, marine transport classification, and whether the supplier can provide a non-DG statement when applicable
  • Free acid and moisture should be reviewed for bag compatibility, caking risk, corrosion concerns, and storage suitability during ocean freight
