关于通知义务，我是否必须考虑在物质被列入候选清单之前生产/进口的物品中该物质的吨位？

Regarding the notification obligation, do I have to take into account the tonnage of the substance in articles produced/imported before the substance was put in the Candidate List?

一旦某种物质被列入候选清单，您必须确定自己是否有义务进行通报。确定通报义务所需的输入之一是该物质在每个日历年度进口/生产的物品中的吨位（如果该物品在通报义务开始前的三年内进口/生产，则为前三年的平均值）。在计算时，您必须将整个日历年度（即，如果适用，也包括该物质被列入候选清单之日之前的年份）的进口/生产的物品吨位计算在内。但是，如果没有三年的平均值，通报人将需要依赖前一年的吨位。

Once a substance enters the Candidate List you have to determine if you have the obligation to notify. One of the inputs needed to determine this is the tonnage of the substance in imported/produced articles per calendar year (or the average of the three previous years if the article has been imported/produced during three years before the start of the notification obligation). In this calculation, you have to include the tonnage in articles imported/produced for the full calendar year, i.e. if applicable, also before the date of the inclusion of the substance in the Candidate List. However, if the three year average is not available, the notifier will need to rely on the amounts of the previous calendar year.
