答案（中文）
是的，你需要。CLP 第 39(b) 条适用于所有危害。这包括，当混合物投放市场，且由于含有特定物理危害物质而需要被归类为物理危害物质时，必须通知混合物中包含的该物质。需要注意的是，混合物所属的物理危害类别可能与造成危害的物质的类别不同。如有疑问，应寻求专家判断。
Answer (EN)
Yes, you do. CLP Article 39(b) refers to all hazards. This includes notification of a substance classified for a particular physical hazard and contained in a mixture whenever the mixture is placed on the market and needs to be classified for a physical hazard due to the presence of that substance. It should be noted that the physical hazard class to which the mixture belongs could be different from that of the substance(s) causing the hazard. Expert judgment should be sought in case of doubt.
