OTC专论符合性评估：出口前必做的成分与标签自检
出口美国的OTC化妆品须在立项阶段完成OTC专论（21 CFR）符合性评估，确认活性成分、浓度与标签均落在专论允许范围。本文给出企业可执行的自检清单，帮助提前排雷、避免上市后被扣留。
米诺地尔生发美国OTC合规：2%与5%浓度及NDC注册要点
米诺地尔外用生发产品以2%与5%两种浓度在美国作为OTC药品销售，须符合FDA专论并标注Drug Facts。5%适用于男性，2%多用于女性，均须完成NDC注册与工厂登记。中国防脱发产品出口美国若宣称促生发，须按药品路径合规，不可归入普通化妆品。
止汗剂美国OTC合规：氯化羟锆铝活性成分、NDC强制注册与除臭剂区别
美国止汗剂属OTC药品，活性成分以氯化羟锆铝、氯化铝、氯羟铝等铝盐为主，须按21 CFR 350专论配制并完成NDC强制注册。止汗剂(减少排汗)与除臭剂(仅掩盖气味)法律属性不同，后者通常不作药品监管。出口企业须区分两类产品合规路径。
祛痘产品美国合规边界：过氧化苯甲酰与水杨酸浓度上限及药妆误区
美国FDA将祛痘产品按OTC药品监管，过氧化苯甲酰限2.5%—10%、水杨酸0.5%—2%、硫磺3%—10%。所谓“药妆”在美国并非法定类别，宣称祛痘即构成药品声称，须符合21 CFR 333专论并完成NDC注册。出口企业应避免以化妆品名义规避药品合规。
防晒OTC专论GRASE活性成分解读与2026 Bemotrizinol新规
2026年FDA将Bemotrizinol纳入OTC防晒专论，叠加CARES Act行政命令框架，防晒剂合规迎来新变化。目前仅氧化锌与二氧化钛被认定为GRASE安全成分，其余化学防晒剂因数据不足需重新评估。出口企业须按21 CFR 352专论调整配方与标签，避免上市后被扣留。
