Mono Ethylene Glycol (MEG) CAS 107-21-1 Industrial Grade for Antifreeze and Polyester Applications
Sourcing candidate for Mono Ethylene Glycol (MEG), CAS 107-21-1, offered for overseas buyers seeking industrial-grade material for antifreeze, polyester resin, solvent, and dehydration-related applications. Buyer should verify the supplier COA against required MEG purity, water content, acidity, color, diethylene glycol content, appearance, and packing format before RFQ confirmation. The source listing contains several specification inconsistencies that require clarification before purchase.

CAS No.: 107-21-1Industrial chemical raw material / glycol solventNeeds specification verification before RFQ
Boiling range listed: 196-199 °C; buyer should confirm test method
Melting point listed: -1 °C; buyer should verify against specification sheet
Grade listed: industrial grade
Purity or concentration: not stated; request COA with assay
Key impurity checks: water, acidity, color/APHA, diethylene glycol, aldehydes, ash, iron, chloride, sulfate if relevant to application
HS code listed: 28211000; appears inconsistent for MEG and should be verified by exporter/importer

Package and route
Packing notes
Source page lists 25 kg/PP bag, which is inconsistent with MEG being a liquid; request confirmation of actual liquid packaging.
Common RFQ packing options to confirm: drum, IBC, ISO tank, flexitank, or bulk shipment.
Confirm net weight, palletization, seal type, container loading quantity, and whether packaging is suitable for export transit.
Request recent packing photos, label sample, batch number format, and shelf-life statement.
Confirm whether samples are available and whether sample packaging matches export documentation requirements.
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
Antifreeze and coolant formulation subject to buyer’s formulation and compliance review
Polyester, resin, and fiber-related industrial applications
Industrial solvent or intermediate use where MEG specification is suitable
Gas dehydration-related procurement where grade, purity, and impurity limits are confirmed
Chemical distribution in markets requiring export documentation and batch traceability
How we compare
Sourcing options
Request verified industrial-grade MEG with full COA and English SDS before pricing comparison.
Ask for polyester-grade or fiber-grade MEG if low impurity and color requirements are critical.
Compare drum, IBC, flexitank, ISO tank, and bulk supply options based on destination port, volume, and storage capability.
Use third-party inspection for first orders or when marketplace specifications conflict with expected MEG properties.
Confirm whether the supplier can support long-term monthly volume, spot cargo, or sample-to-commercial order progression.
Human review
Compliance notes
Request SDS in English, COA, TDS/specification sheet, packing list, commercial invoice, certificate of origin if required, and transport classification details.
Verify CAS, molecular formula, EC number, grade, assay, and impurity limits before contract confirmation.
MEG is a toxic industrial chemical; buyer should confirm local import, storage, workplace, and end-use requirements with qualified compliance personnel.
Confirm DG/non-DG transport status for the shipping route, carrier, package size, and applicable regulations; do not rely only on marketplace description.
Check whether the supplier can provide export-ready labeling and documentation aligned with destination-country requirements.
No regulatory clearance, import approval, or unrestricted-use status should be assumed from the listing.

Questions to confirm
Please provide your latest COA for MEG CAS 107-21-1, including assay, water, acidity, color/APHA, DEG, aldehydes, ash, iron, and other routine impurity items.
Is the product industrial grade, polyester grade, antifreeze grade, or another grade? Please provide the full specification table.
Please confirm the actual appearance and packing, since the listing states powder and 25 kg/PP bag while MEG is normally supplied as a liquid.
What is the standard export packing: drums, IBCs, ISO tank, flexitank, or bulk? What is the net weight per package and loading quantity per 20 ft container?
Can you provide English SDS, TDS, COA, packing list, invoice, certificate of origin, and transport classification information before shipment?
What is the confirmed HS code used for export from China, and can you align documents with the buyer’s customs broker review?
What is the minimum order quantity for commercial export orders and for pre-shipment samples?
What incoterms are available: EXW, FOB, CFR, CIF, or DAP? Please specify loading port and estimated lead time.
