Do i have to buy shipping in my seller central?

Hello my fellow sellers

In order to be eligible for SFP sellers have to use amazon buy shipping which means you have to buy shipping lables from amazon

i cannot get onboard with Amazon shipping as my business entity is based in China (feels like a bit disciminatory against chinese)

My questions is that can i buy shipping from other people's amazon shipping central (not seller central) in this case would this order be considered as buy shipping from amazon?

Kind regards

Ben
