Sensitive shipments? Use a warning label! Warning labels are usually fluorescent self-adhesive labels for use on shipments such as packages and pallets. The label often contains a familiar warning symbol and or text that very clearly indicates to the forwarder or warehouse staff important information for how to handle the shipment. All our warning labels are produced in Europe, consistently high quality with silicone-treated release paper for easy and safe removal. Through our local suppliers, we also have the opportunity to customize the labels with unique messages.
