Dear All,

What is the process in which individuals are using to verify that the raw material lots comng from the correct manufacturer's address, supplier's address and vendor's address? We are currently expecting a sign verification from the source (vendor, manufacturer, supplier) that these are the correct address for each lot received.

We have to use suppliers and vendors due to the small quantities required.

Vendor is a individual that one places the order. It can store product or not.

Supplier is the another option to place the order. They do store the product and may redrum and test the product.

Manufacturer is self explanatory.

speculating here...

Vendors do not assign lot numbers, those are on the packages that come from suppliers.

Get material and check with the supplier about having a CoA for your lot faxed to you (if it is not already available on the internet). If it is very sensitive material, it should be packaged with indicators that will tell you if it got too hot, wet, shocked etc. etc.

Hi All,
Does anybody know the industry standard interval for requalifying the vendor's qualification of raw material? The guidance calls for periodic requalification, but it doesn't specify whether it is to be annual, biennial, etc. Any suggestion would be appreciated?
P.S. My apology to Srdales, I don't mean to steal your post...
