1. Whether authorization is required to sell branded products depends on the purchase channel. If there is no authorization letter, only the voucher from the formal purchase channel (that is, the purchase invoice) is acceptable.

2. If the purchase channel is normal and it is not a fake or shoddy brand product, it does not require authorization from the brand owner or brand manufacturer. Sell ??authentic brand products, no authorization required.

3. For example: selling branded mineral water, as long as it is not counterfeit and shoddy, and the purchase channel is normal, even if there is no authorization letter from the manufacturer, it does not constitute infringement of the branded mineral water produced by the manufacturer.
