Amazon Global Logistics, should I use it?

Hi! Im new to FBA and was hoping to get help with shipping.

My manufacturer is located in Guangzhou China, the nearest Amazon Global Logistics port is Shenzhen.

The Manufacturer quoted me $1,850 to ship to the states.

I know that AGL would be cheaper thus me looking into alternatives.

Would yall recommend I ask the Manufacturer to ship to Shenzhen then AGL take over shipping to the states? (If that's even possible)

Again, I'm new to this so any advice is greatly appreciated🙏🙏
