What buyers usually review first
Quality review usually starts with how testing, batch consistency, cleanroom conditions, and process discipline are presented for technical evaluation.
Which files are commonly requested
Buyers often request COA, specification sheets, identity-related references, and other supporting files that help confirm how batch-level information is organized.
When sample discussion usually starts
Sample discussion usually becomes more practical after the team has reviewed core technical files and confirmed that the quality presentation fits the current project stage.
What the next step usually is
If the product remains relevant after technical review, the next step is usually to request files, discuss samples, or move into MOQ, lead time, and supply follow-up.
