EDTA Tetrasodium / Disodium Powder Candidate for Cosmetic and Industrial Chelation
Buyer-facing sourcing candidate for EDTA-4Na and EDTA-2Na white crystalline powder offered as chelating agents for cosmetic, detergent, water treatment, textile, paper, and industrial formulations. Key pre-RFQ checks should focus on confirming the exact salt form, CAS number, assay basis, NTA limit, heavy metals, pH, chelation value, particle form, and document readiness for export.

Package and route
Packing notes
Standard packing referenced: 25 kg bag.
Confirm inner liner, moisture barrier, palletization, and container loading plan for sea freight.
Ask whether packaging is suitable for long transit humidity exposure and whether export marks can include product name, batch number, net weight, gross weight, origin, and hazard status.
MOQ shown on source page: 5,000 kg; confirm sample, LCL, pallet, and FCL options.
Supplier states stock near Qingdao Port; verify current availability, lead time, and port of loading.
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
Chelating agent in cosmetic and personal care formulations, subject to buyer grade and compliance checks.
Complexing agent for detergent and cleaning formulations.
Water treatment additive for metal ion control, subject to local requirements.
Textile dyeing auxiliary for improving dye performance and reducing metal ion interference.
Papermaking and pulp processing additive for scale and metal ion control.
Industrial formulation ingredient where EDTA salt form, pH, and chelation value are specified.
How we compare
Sourcing options
Request separate quotations for EDTA-4Na and EDTA-2Na with no substitution unless approved.
Source by grade: cosmetic grade, food-adjacent grade, or industrial/technical grade with separate impurity specifications.
Use pre-shipment third-party inspection for assay, NTA, heavy metals, and packaging condition.
Start with sample or pilot-lot validation before bulk import.
Compare 25 kg bag, palletized LCL, and FCL purchasing based on moisture protection and landed cost.
Require batch-specific COA and SDS review before issuing purchase order.
Human review
Compliance notes
Do not rely on the marketplace title for grade claims; request grade-specific COA and specification sheet for cosmetic, food, technical, or industrial use.
CAS number is missing from the source listing; confirm CAS for the exact EDTA salt and hydration form before import classification.
Request SDS in GHS format, COA by batch, TDS/specification sheet, certificate of origin, packing list, commercial invoice, and HS code confirmation.
HS code shown: 2922499990; buyer should verify local tariff classification with customs broker.
Clarify whether the material is non-DG for the intended transport mode and obtain a transport classification statement if required by carrier or forwarder.
For cosmetic or food-adjacent applications, request impurity profile, heavy metals, NTA limit, microbiological requirements if applicable, and compliance declarations relevant to the destination market.
No regulatory approval or market-access guarantee should be assumed from supplier claims; confirm requirements with destination-market compliance teams.
Check whether the product is EDTA-4Na, EDTA-2Na, or an interchangeable offer; substitutions should not be accepted without written approval.
