What is the TDG (Transportation of Dangerous Goods) status of each product?
Coal Tar is not controlled by TDG at all so you do not need any licenses or certificates for this product. Sealer IS controlled by TDG, so in-order to transport it anywhere the driver is required to have a Transportation of Dangerous Goods Certificate. This is because Sealer is solvent based which makes it very flammable and TDG controlled.
