Jack - The problem is most certainly "up-stream" from the manufacturer and, unfortunately, many are either not concientious or are being misled by material certifications.
I guess a lot depends on where the counterfeits are added to the supply stream. A lot of distributors I know work directly with the manufacturer as their supply source. Or or you talking about more up stream problems?
I would be interested in learning how distributors protect themselves, and their customers, from counterfeit and substandard materials. Insisting on material certification does not seem to be enough, as these documents are frequently falsified. Base metals and alloys seem to be particularly prone to such practices, and many times are already in a finished product or component that may seem, on the surface to be legitamate.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
