想要諮詢泰國化妝品的申請準備與報價: 目前預計有防曬產品想要出口至泰國,已準備相關之成分文件,想請問關於SPF宣稱準備目前已有in-vitro,是否需額外準備in-vivo? 此外若委託銀們進行申請,還需要哪些文件以及報價?

ElendiLabs

As you are aware, sunscreen products fall under high-risk cosmetics in Thailand and are subject to a higher level of regulatory scrutiny, particularly in relation to claims and supporting documentation. Based on the information provided, additional in-vivo testing is not necessarily required at this stage, although this will ultimately depend on the final formulation, claims, and positioning strategy.
