Who uses this page

Target buyers

  • Industrial acid importers in India
  • Food additive distributors requiring documented lactic acid solution
  • Chemical trading companies serving Africa and Middle East markets
  • Acidity regulator and preservative ingredient buyers
  • Beverage, condiment, dairy, and fermentation ingredient procurement teams subject to local compliance checks
  • Industrial formulation buyers needing CAS/spec verification before RFQ
Before matching

Documents to check

  • CAS number, grade, assay, and impurity profile
  • SDS, COA, TDS, HS code, and transport classification
  • Destination-market import documents before supplier matching
Package and route

Packing notes

  • Listed packing: 25 kg plastic drum
  • MOQ shown on page: 25 kg
  • Sample availability is mentioned; sample terms should be confirmed directly with supplier
  • For export RFQ, request palletization details, drum material, net/gross weight, seal type, batch labeling, and container loading quantity
  • Confirm whether larger export packs such as IBC drums or bulk drums are available for industrial buyers
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

  • Food acidity regulator sourcing where local regulations and food-grade documentation are confirmed by the buyer
  • pH adjustment ingredient procurement for approved industrial or food applications
  • Ingredient distribution for beverage, condiment, dairy, brewing, and pickling sectors where permitted
  • Industrial lactic acid solution sourcing requiring confirmed concentration and impurity limits
  • Export RFQ comparison for 25 kg drum or larger drum supply
How we compare

Sourcing options

  • Request 80% lactic acid liquid with full COA and SDS
  • Request food-grade lactic acid with food additive documentation and batch traceability
  • Request industrial-grade lactic acid for non-food applications with technical specification only
  • Request alternate concentrations if available, such as higher assay lactic acid solution
  • Request India-focused export quotation with Incoterms, DG shipping confirmation, and landed-cost document set
Human review

Compliance notes

  • Verify CAS 50-21-5 and product identity against COA before purchase order confirmation
  • Grade claims are inconsistent: page references food grade, industrial grade, and food additive use; buyer should specify required grade and applicable standard
  • Request current COA, SDS, TDS/specification sheet, certificate of origin, packing list, invoice template, and any food-grade documentation if needed
  • Confirm whether the product is exported as lactic acid solution at 80% concentration and whether it matches the buyer’s import tariff and local registration requirements
  • Check dangerous goods classification, transport restrictions, and corrosive/acidic liquid shipping requirements with the supplier and freight forwarder before booking
  • No regulatory approval or import clearance should be assumed from marketplace listing text
  • Confirm shelf life, batch traceability, manufacturing date, and storage condition statement on documents

Questions to confirm
  • Please confirm the exact concentration: is the export product 80% lactic acid solution, or is another assay such as 88%, 90%, or 98.8% available?
  • Please clarify the grade: food grade, industrial grade, feed grade, or technical grade? Which standard does the batch comply with?
  • Can you provide a recent COA for CAS 50-21-5 showing assay, color, density, heavy metals, chloride, sulphate, ash, arsenic, lead, mercury, and microbial/food parameters if applicable?
  • Is the listed 98.8% purity compatible with the 80% lactic acid content, or does it refer to a different grade?
  • What is the normal export packing for India, Africa, and Middle East shipments: 25 kg drum, 250 kg drum, IBC, or other?
  • Can you provide SDS in English and confirm DG classification, UN number if applicable, packing group if applicable, and shipping marks?
  • What is the minimum order quantity for export pricing, and what price tiers apply by drum, pallet, and container load?
  • What documents can be supplied with shipment: COA, SDS, TDS, certificate of origin, health certificate, halal/kosher certificate, or food additive compliance documents?
Checks before quote
  • Verify CAS 50-21-5 and product identity against COA before purchase order confirmation

  • Request current COA, SDS, TDS/specification sheet, certificate of origin, packing list, invoice template, and any food-grade documentation if needed
  • Confirm whether the product is exported as lactic acid solution at 80% concentration and whether it matches the buyer’s import tariff and local registration requirements
  • Check dangerous goods classification, transport restrictions, and corrosive/acidic liquid shipping requirements with the supplier and freight forwarder before booking
  • No regulatory approval or import clearance should be assumed from marketplace listing text
  • Confirm shelf life, batch traceability, manufacturing date, and storage condition statement on documents
