Dichloromethane (DCM, CAS: 75-09-2) is classified as a Class 6.1 toxic substance under the Catalogue of Hazardous Chemicals (2015 Edition). Due to its volatility and toxicity, its export packaging must comply with strict international transport standards to ensure safe handling and delivery.
Packaging Standards for Dichloromethane
Leak-Proof Design:
DCM must be stored in special corrosion-resistant containers. Common export packaging includes 250 kg galvanized steel drums, 300 kg IBC tanks, or ISO tanks for bulk shipments. Each container must meet UN hazardous material packaging standards, ensuring a leakage rate ≤ 0.001 g/h. For additional protection, an inner polyethylene lining (≥0.2 mm) is often used to prevent corrosion and vapor leakage.
Labeling and Isolation:
Export packages must bear hazard labels, including "Toxic Substance" and "Flammable Liquid," along with UN number UN1593. During storage and transport, dichloromethane must be kept away from oxidizing agents, acids, and sources of heat. Proper isolation and ventilation are essential to prevent vapor accumulation.
Compliance Process:
Before export, dichloromethane is subject to dangerous goods inspection and certification under IMDG (International Maritime Dangerous Goods) and IATA (International Air Transport Association) standards. Packaging and documentation must comply with GHS labeling and customs safety declarations.
Quality Control
Gneebio follows ISO 9001 and ISO 14001 management systems. Every batch of packaging is tested through pressure, stacking, and drop tests to ensure integrity during long-distance transport. Packaging options are selected to balance cost efficiency and safety-for example, lightweight metal drums for short-distance delivery and high-strength ISO tanks for bulk export.
Conclusion
Because dichloromethane is both volatile and toxic, there is zero tolerance for packaging errors during export. Companies must strictly adhere to international hazardous goods regulations, select certified packaging materials, and cooperate with professional logistics providers to ensure safe and compliant global transport.
