Onion sample: how much should we pay and what should it prove?

admin

A supplier quoted us a sample of Onion for Gansu / Shandong. What is a normal sample cost, and what should the sample prove beyond appearance?

Sample cost is usually 30-60 USD including courier. It should prove 5-8cm, red/yellow, mesh bag and come with the lot-level document: phytosanitary, CO. A sample without a lot code proves nothing.
