ISO 9001:2015 (Houston Location):April 2, 2019

As part of the International Standards of Organization, the ISO 9001:2015, in conjunction with our ISO 14001 & OSHAS 18001, provides a guideline for CLS to establish and maintain and Environmental Health and Safety (EHS) system that improves all areas of our organization. Specifically, the standards outlined in the ISO 9001 certification process shows our customers we are dedicated to:

  • Minimizing mistakes
  • Improving reporting and communications
  • Providing better quality products and service
  • Establishing a more reliable production scheduling and delivery


Our ISO 9001:2008 certification forces us provide a workable management system that focuses on the important areas of CLS’s business and improving efficiency.


Through the State of Texas, we are certified as a Historically Underutilized Business (HUB) which officially recognizes CLS as a desirable partner for any state or local agency’s network equipment procurement, implementation, or asset recovery solution.


CLS is certified as an Economically Disadvantaged Woman Owned Small Business (EDWOSB) and Small Disadvantaged Business (SDB) through the Small Business Administration. Since all federal contracting guidelines require these certifications, CLS qualifies as an ideal IT, IP, and telecommunications solution provider for the federal government.

OHSAS 18001-2007 (Houston Location):April 2, 2019

The OHSAS 18001:2007 standard is an international standard that helps CLS identify, control and decrease the risks associated with health and safety within our work environment. The strict guidelines set by this Occupational Health and Safety Management Certificate indicates the priority CLS places on:

  • The health and well-being of employees, sub-contractors and the public
  • Risk management
  • A proactive, rather than reactive, approach to controls which reduces or eliminates workplace hazards
  • A safer, healthier work environment decreases accidents (downtime) and increases employee motivation (output increase and improvement)


Ensuring and monitoring control over all relevant hazards—resulting from both daily production and the unexpected—allows for a safer and more productive operation.
