答案（中文）
所有物质均须注册：- 定义见 REACH 法规第 3(1) 条；- 每位注册人每年在欧盟境内生产或进口至欧盟的物质数量达到或超过 1 吨；- 除非根据 REACH 法规第 2、9、15 或 24 条的规定，这些物质获豁免注册或被视为已注册；- 无论其是否被归类为危险品。如果您想知道是否必须注册某种物质，应首先查阅注册指南第 2.2 节“注册什么？”。您还可以在其中找到有关豁免注册物质的信息。
Answer (EN)
Registration is required for all substances:- as defined in Article 3(1) of REACH;- manufactured in or imported into the EU in quantities of 1 tonne or more per registrant per year;- unless they are exempted from registration or regarded as being already registered, according to provisions in Articles 2, 9, 15 or 24 of the REACH Regulation;- irrespective of whether they are classified as dangerous or not. If you want to know whether you have to register a substance you should first consult the Guidance on registration, section 2.2- 'What to register?. There you will also find information on substances exempted from registration.
