Urea Fertilizer, Prilled/Granular, CAS 57-13-6, Nitrogen 46% Min
Public sourcing candidate for agricultural-grade urea fertilizer offered as prilled or granular material. The listing title references urea phosphate and CAS 7758-23-8, but the extracted product data identifies urea/carbamide with CAS 57-13-6 and formula CO(NH2)2. Buyers should verify CAS, product identity, grade, nitrogen assay, biuret, moisture, particle size, packing, export documents, and destination-market import requirements before RFQ confirmation.

Packing notes
Standard packing stated as 25 kg, 40 kg, or 50 kg woven/knitting bags with inner plastic liner.
Listing also mentions 1000 kg bag availability; confirm jumbo-bag specification, palletization, liner, and container loading quantity.
Confirm bag marking requirements, batch number format, production date, net/gross weight, and country-of-origin marking.
Request photos of current export packing and recent loading records before shipment.
Confirm whether samples are available and whether sample COA matches the proposed bulk lot.
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Nitrogen fertilizer sourcing for agricultural distribution
Input for fertilizer blending where urea CAS 57-13-6 is specified
Bulk import programs requiring COA-backed nitrogen content and biuret limits
Tender-based procurement requiring packing, origin, and shipment document verification
How we compare
Sourcing options
Request a corrected quotation for urea CAS 57-13-6 if nitrogen fertilizer is required.
Request a separate quotation for genuine urea phosphate only if phosphate fertilizer is required, with matching CAS and COA.
Ask for agricultural-grade, industrial-grade, or feed-grade offers as separate RFQs to avoid specification mixing.
Consider third-party inspection and sealed sample retention for first shipment.
Compare prilled versus granular form based on buyer’s downstream application and local market preference.
Human review
Compliance notes
High priority identity check: title references urea phosphate / CAS 7758-23-8, while product details show urea / CAS 57-13-6. Do not proceed without written confirmation of the intended chemical identity and CAS.
Request SDS, COA, TDS/specification sheet, commercial invoice template, packing list template, certificate of origin availability, and any required fertilizer registration documents for the destination market.
Confirm whether the product is intended only for fertilizer use or also claimed for feed use; feed-grade supply may require different specifications and destination approvals.
Verify export controls, sanctions screening, end-use declaration requirements, and fertilizer import licensing for the buyer’s country.
Confirm dangerous goods classification with supplier SDS and carrier; do not rely on marketplace text for DG status.
No regulatory approval or import clearance should be assumed from the listing alone.
Check heavy metals, insolubles, biuret, moisture, anti-caking agent, and contamination limits against buyer and destination standards.
