Hi, I want to know is there a difference between an authorized distributor and an authorized stocking distributor? How to understand the word "stocking"? Does it mean it should have a warehouse? I find such a classification, but still there is no explanantion of the key words used. "Octopart classifies distributors into three buckets: Authorized Distributors, Non-Authorized Stocking Distributors, and Non-Authorized Dealers. It is important that buyers understand the differences between them. As a general rule of thumb, if an authorized source is available, you should buy from them.
