Quality Assurance - ISO Certification

All PQ plants (USA) are certified to the ISO 9001:2000 Quality Standard (National Quality Assurance). This certification is part of our Operational Platform and our Continuous Quality Improvement (CQI) program.

An independent auditor audits our plants at least once a year (surveillance audits) depending on plant size. Third party internal audits are also carried out as part of our Quality Assurance program.

The PDCA methodology of the ISO Quality system is being combined with the DMAIC methodology in the Six Sigma system as part of our Continuous Quality Improvement program.

At PQ we are committed to Customer Satisfaction and Continuous Quality Improvement.
