Short answer
If the current supplier cannot make the right sample, delays repeatedly, or sends samples that miss the brief, another China-side sample source can help you compare options before committing to a larger supplier decision.
Guide
Sometimes the issue is not shipping or communication. The current sample source may simply be the wrong path.
If the current supplier cannot make the right sample, delays repeatedly, or sends samples that miss the brief, another China-side sample source can help you compare options before committing to a larger supplier decision.
Do not restart the whole sourcing process blindly. Define the target sample, use the current sample as a comparison point, keep records, and decide whether the new source is meaningfully better.
When suitable, we can help look for another China-side sample source and organize the next sample path. This supports comparison; it does not make us your purchasing agent or guarantee final supplier quality.
