对于候选清单中涉及硼玻璃制品生产但并不存在于这些制品中的某些硼物质，我是否需要通知并向供应链下游传达信息？

对于候选清单中涉及硼玻璃制品生产但并不存在于这些制品中的某些硼物质，我是否需要通知并向供应链下游传达信息？

Do I need to notify and communicate information down the supply chain for certain boron substances included in the Candidate List, which are involved in the production of boron glass articles but not present as such in these articles?

根据 REACH 第 7(2) 条的规定，企业须履行通报义务，并根据 REACH 第 33 条的规定，向供应链下游进行信息沟通。候选清单中的某些硼物质，例如三氧化二硼、硼酸和四硼酸二钠，会参与生产含有“硼硅酸盐玻璃”的物品。在这些过程中，硼物质通常首先经过化学转化，转化为玻璃制品。玻璃制品随后被加工成物品。在这些通常情况下，硼物质会完全转化，不会以原样存在于最终的玻璃制品中。因此，企业无需根据 REACH 第 7(2) 条的规定进行通报，也无需根据 REACH 第 33 条的规定向供应链下游进行信息沟通。请注意，企业仍有责任评估其对候选清单中硼物质的具体使用情况，以确定这些物质在“硼硅酸盐玻璃”制造过程中是否完全转化为玻璃，以及候选清单中的物质是否存在于硼玻璃制品中。

The obligation to notify under Art. 7(2) of REACH and to communicate down the supply chain under Art. 33 of REACH only applies to articles which contain Candidate List substances. Certain boron substances included in the Candidate List, such as diboron trioxide, boric acid and disodium tetraborate, are involved in processes leading to the production of articles containing “borosilicate glass”. In these processes, the boron substances are usually first chemically transformed into a manufactured glass substance. The glass substance is subsequently processed into articles. In these usual cases, the boron substances are completely transformed and are not present as such in the final glass article. Consequently, there is no obligation to notify under Art. 7(2) of REACH, nor to communicate information down the supply chain under Art. 33 of REACH. Please note that it remains the responsibility of companies to assess for their specific use of the Candidate List boron substances whether these are completely transformed into glass in the manufacture of “borosilicate glass” and whether the Candidate List substance is present in the boron glass articles.
