Packing notes
Reported packing: 270 kg sealed galvanized or black iron drums
Source page states drums are filled to 80% capacity; confirm net weight, gross weight, drum specification, and palletization
Request photos of export drum marking, batch label, UN/DG labels, and seal condition before shipment
Confirm availability of FCL quantities, mixed-container restrictions, and sample policy if permitted
Ask whether supplier can provide export packing suitable for sea freight under applicable DG 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
Industrial solvent sourcing where dichloromethane is permitted by local law and buyer EHS policy
Formulation or process solvent evaluation with batch COA and impurity review

How we compare
Sourcing options
Request quotation by grade: 99.90%, 99.50%, or 99.20%
Request batch-specific COA and SDS before price confirmation
Request third-party inspection for purity, water, acidity, and packaging condition
Request FCL quote with DG-compliant sea freight documentation
Request supplier correction of CAS/EINECS fields before purchase order issuance
Human review
Compliance notes
CAS discrepancy requires correction before publication or procurement: CAS should be checked against COA, SDS, label, and commercial invoice
Dichloromethane is a hazardous chlorinated solvent and may be restricted or subject to workplace, environmental, and import controls in many destinations
Do not rely on the phrase pharma-grade unless the supplier provides pharmacopeial, GMP, residual impurity, and traceability documentation accepted by the buyer's quality unit
Request current SDS in GHS format, COA by batch, TDS/specification sheet, transport classification, UN number, packing group if applicable, and export documents
Confirm DG classification, marine transport acceptance, port restrictions, and carrier requirements before shipment booking
Buyer should verify compliance with local rules such as chemical inventory listing, REACH/UK REACH, TSCA, PIC/export controls, occupational exposure controls, and end-use restrictions where applicable
No regulatory guarantee is implied by the source listing; destination-country compliance remains subject to buyer review
