DCM Supply from China: Specification, Stabilisation and Shipment Documents
This is the supply page for DCM (methylene chloride, dichloromethane, CAS 75-09-2, UN 1593, class 6.1, packing group III), the volatile chlorinated solvent used in paint stripping, adhesive formulation, metal degreasing and extraction. Minimum order, container load, loading port, lead time and packing are confirmed in the quotation; they are not fixed on this page.
We are a trading company: the product is produced by a licensed Chinese producer and supplied under our own documentation. Group member Quzhou Huafu handles warehousing and cylinder filling for the cylinder grades in our range (R22, R134a, R410A); DCM is quoted on the packing terms stated in the quotation.

Solvent volumes are usually quoted by net weight, and for a class 6.1 packing group III product the packing form changes both the quantity per consignment and the paperwork that travels with it. Send the quantity, destination port, packing form and any specification the COA should name, and the quotation will state minimum order, loading port and lead time together with the packing that applies.
Specification basis
DCM is specified on more than a purity figure. Water content drives hydrolysis, so the grade is supplied stabilised; the stabiliser and its concentration are declared on the batch COA rather than fixed on this page, and they are what an extraction or stripping process actually has to work around. Purity, water, acidity and residue are reported per lot against our own specification, each result with the method behind it, and no value is carried over from an earlier lot — the certificate that counts is the one issued for the lot you receive.
Where a buyer names a standard — a national grade, an industry grade, or the buyer’s own purchasing specification — the quotation is made against that document and the COA names it as the basis of analysis. That matters more for a solvent than for a refrigerant: two DCM certificates showing similar purity can still behave differently if the water and stabiliser lines are not read against the same specification, which is the point the specification guide below takes apart.
Documents per shipment
- Certificate of analysis, one per lot, including the stabiliser line and the specification it is measured against
- Safety data sheet, current version for the grade supplied
- Transport document naming UN 1593, class 6.1, packing group III
- Packing list showing net weight per package
- Dangerous goods packaging certificate for the packaging used
