We have a comprehensive selection of the most common UN numbers preprinted HazMat placards in stock and ready to ship to you quickly. Preprinted placards assist you to avoid the hassle of hand numbering your placards, and sidestep the potential risk of incorrectly numbering your hazardous materials shipments. FlipPlacards.com’s preprinted placards provide you with an incredibly convenient way to tag your hazardous materials shipments by UN regulations. You can choose between two products. First, we offer a long lasting self-adhesive removable vinyl placard, which mounts simply to shipment surfaces and can be peeled off effortlessly if switching hazardous materials. The other offering is a heavyweight polycoated tagboard, which is resistant to water damage and slides in easily to standard placard holders.
