A supplier quoted us a sample of Walnut Kernel for Yunnan / Xinjiang. 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 light halves, vacuum pack and come with the lot-level document: phytosanitary, CO. A sample without a lot code proves nothing.
