Start with the exact product you need, then compare samples and the supplier’s ability to meet the specification.
Confirm the specification
Record dimensions, colour assortment, packaging and quantity units so quotations cover the same requirements.
Evaluate physical samples
Compare colour application and handling under the same conditions. Keep the approved sample as a reference for the order.
Check documentation
Ask which exact product and model a report covers. Confirm your destination market requirements before approving an order.
