The information requirements in REACH registration depend significantly on the annual tonnage band which is the sum of annual manufactured and imported quantities. There are four tonnage bands under REACH: 1 to 10 tonnes, 10 to 100 tonnes, 100 to 1000 tonnes, and 1000 or more per year. The higher the tonnage band is, the greater amount of data would be needed. For instance, a Chemical Safety Report should be submitted if the substance is manufactured or imported in quantities of more than 10 tonnes annually. Therefore, it is important to determine the tonnage band correctly.
