Using the Term "Counterfeit"
“Quality independent distributors do not typically use the term "counterfeit" unless the manufacturer of the product states that they have determined the product is counterfeit in writing. Instead independent distributors typically condition the term "counterfeit" with the word "suspect", meaning that based on the expertise that resides within that independent distributor's business that they suspect that the part may indeed be counterfeit.”
