How do you balance FBA prep speed and QC from China? Struggling to optimize both.

Been in the Amazon space for a while now, and one issue that keeps tripping me up is finding that sweet spot between fast FBA prep and solid quality control when shipping from China.

Right now, I work closely with a supply chain team at Fulfilment Pros out of Shenzhen, they’ve been great on the operational side (especially with partnerships like YunExpress and 4PX), but as volumes increase, even small bottlenecks in inspection → prep → ship start to hit harder.

The main pain points I’m seeing:

• Some suppliers cut corners on QC and assume the prep center will catch everything.
• Amazon’s FBA requirements keep shifting (especially on labeling), and not all centers adapt quickly.
• Air lanes are reliable, but coordinating timing with multiple moving parts gets chaotic.

So I’m curious, how are others here managing this? Are you relying on in-house teams? Hybrid systems? Regional prep centers that’ve nailed both QC and FBA compliance?

Not fishing for leads, just genuinely trying to compare notes and tighten up the process. The more we scale, the more important this part becomes.

Would love to hear what’s worked (or failed) for you.
