Buyer-facing sourcing candidate for 85% phosphoric acid, CAS 7664-38-2. The source page lists both industrial/fertilizer positioning and food-grade FCC-style specifications, so buyers should confirm intended grade, assay basis, impurity limits, packaging, DG Class 8 export documentation, and destination-market acceptance before RFQ or sampling.

Package and route
Packing notes
Listed packing options include 35 kg HDPE drums, 1600 kg IBC totes, and 35 MT flexitank; confirm availability by destination and carrier acceptance.
Confirm net weight, gross weight, palletization, drum material, venting or closure type, and container loading plan before booking.
For corrosive liquid export, request packaging compliance details suitable for DG Class 8 transport and destination import requirements.
Ask whether samples are available only for evaluation and whether sample packaging/documentation matches the declared grade.
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
Fertilizer and phosphate-based formulation procurement, subject to industrial/fertilizer-grade confirmation
Food ingredient sourcing as acidulant or pH-adjustment raw material, only if food-grade documentation is verified
Industrial formulation requiring 85% phosphoric acid concentration and defined impurity limits
Distributor stock purchase for customers requiring CAS 7664-38-2 acid with COA-backed specifications
Bulk corrosive liquid sourcing where DG Class 8 export handling and documentation are required
How we compare
Sourcing options
Request quote for 35 kg drum packing for smaller distributor lots or mixed container planning.
Request IBC packing for industrial buyers balancing handling efficiency and batch traceability.
Request flexitank or bulk option only after confirming DG acceptance, route suitability, and destination unloading capability.
Ask supplier to quote both industrial-grade and food-grade options separately with corresponding COA templates.
Use pre-shipment third-party inspection for assay, impurity profile, packing condition, labels, and document consistency.
Confirm Incoterms such as FOB, CFR, or CIF and verify DG surcharges and carrier booking constraints.
Human review
Compliance notes
CAS/spec identity should be checked against COA, SDS, product label, and commercial invoice before purchase.
Source page has a grade-positioning mismatch: raw title states industrial grade for fertilizer manufacturing, while detailed specification claims food grade and FCC/Food Chemical Codex alignment.
DG awareness: source lists Hazard Class 8 corrosive; buyers should request current SDS, transport classification, UN number, packing group, emergency contact format, and carrier-accepted DG declaration.
Document readiness listed by supplier includes Commercial Invoice, Packing List, COA, FORM E Certificate of Origin, Health Certificate, Bill of Lading, and REACH Report; verify destination-specific requirements separately.
Do not rely on listing certifications alone. Request copies of ISO 22000, Halal, Kosher, FCC/BP/USP conformity statements if relevant to the end use.
HS code on source is listed as 17029000, which appears inconsistent for phosphoric acid; buyer should confirm correct HS code with customs broker before import.
For food, feed, fertilizer, or industrial use, confirm the grade label, impurity profile, and permitted-use status in the importing country before contracting.
No regulatory approval, customs clearance, or end-use suitability is guaranteed by the listing data.

Questions to confirm
Is the offered material industrial grade, food grade, or both? Please quote separate specifications if grades differ.
Can you provide a recent batch COA showing assay, arsenic, fluoride, heavy metals, chloride, sulfate, nitrate, reducing substances, color/APHA, and insoluble matter if applicable?
What standard is the quoted material produced against: FCC, BP, USP, GB, industrial grade, fertilizer grade, or buyer-defined specification?
Please confirm CAS 7664-38-2, concentration 85%, molecular identity, and whether the product is orthophosphoric acid without blended additives.
What is the current SDS issue date and transport classification, including UN number, hazard class, packing group, and marine pollutant status if applicable?
Which packaging can be supplied for our destination: 35 kg drums, IBC, ISO tank, or flexitank? Are DG-compatible packages and labels included?
What is the minimum order quantity for export, and can one container be supplied from a single batch or with batch traceability?
What documents can be issued before shipment: COA, SDS, packing list, commercial invoice, certificate of origin, health certificate, REACH-related statement, and DG declaration?
