Extremely hazardous: Class 3.1 low flash point flammable liquid, UN2363, hazardous materials code 31034;
Transportation: Dedicated hazardous chemical vehicle, low temperature, protected from light, anti-static, incompatible with oxidizers/acids;
Export: Requires hazardous chemical qualification, UN packaging, MSDS, and hazardous chemical certificate. Our company has all the necessary documentation.
