Supplier Quality Clauses

The Supplier is encouraged to review the COTSWORKS Supplier Quality Clauses prior to acceptance of this Purchase Order. This document may also be found on the COTSWORKS website, www.cotsworks.com. If the Supplier does not have access to the COTSWORKS website, they should contact [email protected] to obtain a hard copy of these Supplier Quality Clauses.

In the execution of a purchase order, the Supplier must be aware of their contribution to product conformity by meeting the specification and drawing requirements of the component(s) defined in the purchase order and associated documents. Should there be a discrepancy between the purchase order documents and any documents on file with the Supplier, it is the Supplier’s responsibility to reconcile these differences with COTSWORKS before proceeding with an order.


Likewise, the Supplier is responsible for ensuring that the component(s) furnished on a COTSWORKS purchase order meet all applicable safety laws, codes (local, national and international) and directives in accordance with ISO9000 and AS9100. Supplier will support product safety by ensuring robust management of special requirements, critical items and key characteristics. If there are concerns with respect to product safety, supplier will communicate them to COTSWORKS. If there is a concern at the Supplier's premises with respect to safety during the manufacture of the product, Supplier will notify its own employees of the concern and whenever possible, mitigate the concern.


COTSWORKS conducts business to the highest ethical standards and practices. Similarly, COTSWORKS requires that Suppliers conduct business to these same high ethical standards and practices. Supplier must be committed to the highest standards of ethics and business conduct. Supplier must comply with the law, honor commitments, act in good faith, and be accountable. Supplier must strive to maintain full compliance with all laws and regulations applicable to the operation of the business and customer relationships. Supplier must not offer, promise, authorize, or provide, directly or indirectly, anything of value (including business gifts or courtesies) with the intent or effect of inducing anyone to engage in unfair business practices. Supplier will avoid involvement in activities that may be perceived as a conflict-ofinterest. Supplier will respect the legitimate proprietary rights and intellectual property rights of customers and Suppliers and take proper care to protect sensitive information, including confidential, proprietary and personal information.

The Supplier shall ensure all relevant COTSWORKS Purchase Order requirements are flowed down to their sub-tier suppliers. The Supplier’s sub-tier suppliers are responsible to comply with the same specifications and requirements specified on this Purchase Order. The Supplier should make a reasonable effort use American suppliers over international suppliers.

The Supplier shall maintain a quality system meeting the requirements of ISO9001 or AS9100. Third-party registration by an accredited registrar is preferred. Suppliers declaring compliance with no formal accredited registration may require review. For Suppliers not meeting these specifications, COTSWORKS will review and determine if the system implemented is sufficient based on the nature and levels of control required by the parts, materials or services being procured.

The Supplier’s Quality System shall ensure all relevant Purchase Order requirements are met and all applicable processes affecting the final quality of the product in the Purchase Order are rendered by qualified personnel.

The Supplier shall not subcontract in whole, or substantially in whole, performance of any order without prior written consent of COTSWORKS. Requests for subcontracting an order shall be made by the Supplier in writing to [email protected] All affected COTSWORKS part numbers must be listed in the email notification.

A Certificate of Conformance (C of C) shall be provided with each shipment. The C of C can be a separate document, or it can be included as part of the shipping declaration/packing slip text. The C of C shall contain the following information:

  • Supplier name and address
  • Statement that parts conform to the requirements
  • P.O. and line item number
  • Original manufacturer’s name and part number, if applicable
  • COTSWORKS part number and revision number, if applicable
  • Date and identity (hand signature or electronic signature) of quality representative or company official
  • For returned parts, the Supplier shall indicate if the parts are reworked.

The Supplier shall retain all purchasing, production control, quality, manufacturing and manufacturing methods, test, and other related documents associated with the item purchased, for a minimum of ten (10) years after order completion, unless a longer retention period is herewith noted on the Purchase Order.


Records must be stored in an area which prevents loss, damage or deterioration. All data stored by electronic means shall be secure with back-up procedures.


The Supplier shall contact [email protected] to determine disposition of records upon termination of business activity.

COTSWORKS or anyone designated by COTSWORKS, including cognizant government agencies, shall have access to all applicable areas of Supplier’s facilities. This includes suppliers at any level of the supply chain involved in the order and to all applicable records. This right shall also extend to the Supplier’s sub-tier suppliers. The Supplier shall be given reasonable advance notice by COTSWORKS to host such events.

The Supplier is required to notify COTSWORKS prior to shipping material or products with changes in product, processes, components, sub-suppliers / sub-contractors, manufacturing facility locations, packaging, shipping method, molds, or outside processors. The Supplier shall notify COTSWORKS in writing at [email protected] with details of the proposed change(s). All affected COTSWORKS part numbers must be listed in the email notification.


 For items where COTSWORKS has design authority, suppliers are required to obtain written approval from [email protected] prior to instituting any change(s). Suppliers are required to maintain record of all such approvals and have them available upon request.

All affected COTSWORKS part numbers must be listed in the email notification.

For electrical and electronics parts, the plans and acceptance standards shall comply with J-STD001 Requirements for Soldered Electrical and Electronic Assemblies, and ANSI/IPC-A-610, Acceptability of Electronic Assemblies. Other part types shall have workmanship standards in accordance with the relevant drawings, specifications, and the Supplier’s QMS. Workmanship requirements specified on the component specification/drawing or elsewhere on the contract or purchase order shall take precedence over this paragraph.

The use of Pure Tin Plated finishes intended to be soldered are strictly PROHIBITED. These restrictions apply for all types and levels of procurements, with the Supplier responsible for communicating these restrictions to manufactures or sub-tier suppliers as required.

COTSWORKS requires that all suppliers of electrical parts or assemblies shall document and implement a policy compliant to the current revision of SAE AS5553, Counterfeit Electronic Parts; Avoidance, Detection, Mitigation, and Disposition. Suppliers of mechanical parts are to comply with similar methodology by adopting and implementing standard counterfeit mitigation processes applicable to their industry. Suppliers shall purchase material directly from original equipment manufacturers, original component manufacturers, or their authorized distributors.

For electrical and electronic parts susceptible to damage from Electrostatic Discharge (ESD), the Supplier shall establish and maintain a written ESD Control Program compliant to the latest revision of MIL-STD-1686, JEDEC JESD 625, ANSI/ESD S20.20, or equivalent. The Supplier shall take the necessary precautions to ensure that static susceptible devices are adequately protected from ESD damage during handling, manufacturing, testing, inspection, packaging and shipping. Packaging shall be marked with an ESD cautionary note or symbol.
