分类审核相关问题

安可

在运动类别上架了一个产品，但是不久后被亚马逊自动归类为医疗设备，后台链接不能编辑，需要进行分类审核：

At least 1 purchase invoice for products from a manufacturer or distributor
Make sure your invoices:

Dated on or after Mar 19, 2017 (within 180 days)
Include your name and address
Include the name and address of the manufacturer or distributor
Show the combined purchase of at least 10 units
Omit pricing information (optional)

需要三种证书的其中一种：
Certificate of Analysis (COA)
FDA orange book application number
Good Manufacturing Practices (GMP) certificate


想问下，发票那里说的10 units是指10种不同的产品，还是指同一个产品不少于10个数量的意思呢？
问了供应商说只有检测报告，检测报告可以吗？
谢谢！
