Short answer
- Many buyers should check a supplier sample in China before placing a bulk order, especially when the supplier is new, the product has visible quality or packaging risk, or the sample has not yet been compared against the quote and order requirements.
- A China-side sample check does not guarantee that bulk production will be perfect, but it can catch obvious gaps before the buyer spends more money.
- The point is not to inspect everything forever. The point is to make the next decision with better evidence.
