What Are Third Party Sorting Services?

Third party sorting services are independent quality inspections where certified external teams — such as PTI QCS — physically sort, inspect, and certify automotive parts to separate conforming from non-conforming components. For Tier-1 and Tier-2 automotive suppliers in Michigan, this means deploying experienced, ISO and ASQ certified sorting teams directly to your facility — or PTI’s — to contain a quality escape, support a production launch, or respond to an OEM quality hold before it becomes a line shutdown.

PTI QCS is Michigan’s specialist third party sorting provider, serving automotive suppliers and OEM facilities across Detroit, Sterling Heights, Roseville, Windsor, Warren, and Ann Arbor. Our teams are IATF 16949 compliant and can be deployed same-day for emergency sorting events.

Why Michigan Automotive Suppliers Choose Third Party Sorting

OEMs and Tier-1 suppliers are held to zero-defect delivery standards. Quality escapes during line changes, new program launches, or supplier transitions create immediate risk — rejected shipments, production stoppages, and customer chargebacks. PTI QCS steps in with experienced automotive sorting teams to contain the issue, sort the affected inventory, and provide certified documentation that gives your customer confidence.

How PTI QCS Third Party Sorting Works

1. Emergency Deployment — PTI QCS dispatches a certified sorting team to your Michigan facility or our off-site sorting center within hours of your call. We confirm scope, part numbers, and OEM quality requirements before arrival.
2. Sort Setup and Boundary Sample Approval — Our team establishes sort criteria using approved boundary samples and OEM inspection standards. Every inspector is briefed on accept/reject criteria before sorting begins.
3. 100% Part Inspection and Sorting — Each part is individually inspected against the agreed criteria. Conforming parts are certified and tagged. Non-conforming parts are segregated, documented, and held for disposition.
4. Real-Time Reporting — Sort results, defect rates, and part counts are documented in real time. PTI QCS provides shift-by-shift reporting accessible to your quality team and, where required, your OEM customer.
5. Certified Completion Documentation — On job completion, PTI QCS provides a certified sort report including part counts, defect classification, inspector credentials, and containment status — ready for OEM submission.
