CoC's, CoA's ..

Hello all, our buyers departments is having difficulty obtaining CoC's with initial shipments. Would letter of guarantee be the same as a CoC? also applicable to a CoA? Thank you all.

Thank you all. 

An (American) LOG is afaik an American invention. Externally typically regarded  as a Myth.

A COC is a (deliberately) diluted version of a  COA.

The specific value of any of the three items depends on the context which is unknown.

 A LOG or LOCG (continuing), can serve depending on it's use. I wouldn't use it as authentication of anything but if the supplier manufactures the product sent to you, a Letter of Guarantee can be used for that specific item as long as there is notification of any changes in your supplier agreement and you can verify specifications and performance.
