Some individuals are reporting difficulty transporting Sofnolime®, particularly by commercial airline. Occasionally the transport personnel will arbitrarily decide Sofnolime is a hazardous material (HazMat) and either refuse it or levy special HazMat surcharges. Although all carriers have this right, in these cases it might help to have a copy of the Material Safety Data Sheet (MSDS) at hand. Point out section #14 of the MSDS that indicates Sofnolime has no transport restrictions or UN Number. As a last resort, you might produce a copy of the letter from Molecular Products declaring Sofnolime is classified as non-hazardous for transport. As a practical matter, our customers tell us it is nearly impossible to get airlines to accept containers that have been opened, regardless of documentation.
