Procedure for counterfeit electronic parts.


Suspect Part:

A part in which there is an indication by visual inspection, testing, or other information, that it may have been misrepresented by the supplier or manufacturer and may meet the definition of counterfeit part.

Counterfeit Part:

A suspect part that is a copy or substitute without legal right or authority to do so or one whose material, performance, or characteristics are knowingly misrepresented by a supplier in the supply chain.

Examples of counterfeit parts include, but are not limited to:


Original equipment manufacturer.


Authorized distributors only.


The international organization for standardization


The suppliers of material or services are evaluated and selected based on (a) their ability to supply product or services that (a) meets requirements and (b) their risk of supplying counterfeit parts. Parts are always purchased directly from OCMs or from manufacturer's authorized suppliers for Pentek's ADO customers. For non ADO customers, independent distributors are used only after consideration of alternate parts and a reasonable search for material from franchised/authorized sources has been conducted and approval has been obtained from the quality manager and supply chain manager.

Pentek's supply chain maintains a listing of approved suppliers within its system.

Procurement assurance processes for avoiding counterfeit product begins when the customer requests a quotation for a product. In this way Pentek is alerted to a customer's ADO requirement.

Pentek investigates through reporting sources such as ERAI (erai.com) for alerts of suspect counterfeiting incidents. When independent distributors are used for non ADO customers, special precautions are taken. These precautions are approved by the Pentek quality manager and include, but not limited to:

Supplier's approval and source selection considerations include:

Purchasing may place a trial order. Purchasing orders the material or item, receiving inspects the material. If the results are not acceptable, the product is controlled according to nonconforming procedures.

Supply chain and quality management evaluates suppliers to assure that approved/ongoing sources of supply are maintaining effective processes for mitigating the risks of supplying counterfeit electronic parts and to evaluate overall performance using the following criteria:

When a product or service provided does not meet the requirements of the order, purchasing or quality may initiate a supplier corrective action request.

Purchasing documents specify contract/purchase order requirements to minimize the risk of being provided counterfeit parts. These documents may contain, where or when appropriate:

Purchasing staff reviews the information to make sure it is complete, and reviews the approved supplier list to make sure the specified supplier has been evaluated and accepted. If not evaluated and accepted, the supplier cannot be used unless the supply chain manager decides to initiate a trial order pursuant to the above section.

Verification of Purchased Product

Purchased product is verified before use to assure detection of counterfeit parts prior to formal acceptance. The rigor of the verification process shall be commensurate with product risk. Product risk is determined by the criticality of the part and the assessed likelihood of receiving a counterfeit part. Receiving checks the order against purchasing documents to verify the identification, quantity and condition of the items in the order.

Verification may include:

Material Control

If material is identified to be counterfeit, Pentek will contact the supplier/vendor furnishing the material and provide any Pentek data supporting the counterfeit nature of the material. Pentek will discuss options with the supplier for disposition of the affected material in order to prevent re-entry into the supply chain. This may include:
