How to prevent a Controlled Shipping order before it happens
A Controlled Shipping order is the OEM formalizing a loss of confidence in your quality. It is almost always preventable. The suppliers who never reach CSL1 share a few habits: they answer alerts within the hour, close 8Ds with real root cause, and contain proactively during launch.

What actually triggers Controlled Shipping?
Controlled Shipping is rarely the result of one defect. It is triggered by a pattern: a defect reaches the OEM line, it is contained, and then a second escape of the same or a related issue happens before the first is truly closed. That second escape tells the Supplier Quality Engineer the process is not under control, and the formal order follows. The lesson is that the danger is not the first defect, it is the repeat. Prevention is therefore about closing the loop completely the first time, so there is no second escape to escalate.
What habits keep suppliers off CSL1 and CSL2?
| Habit | Why it prevents escalation |
|---|---|
| Respond within the hour | A managed alert reads as control; a chased one reads as risk |
| Verify both root causes | Fixing why it occurred and why it escaped stops the repeat |
| Preventive GP-12 at launch | Catches launch defects before they reach the line |
| Keep a voice in the plant | Small concerns are answered in person before they formalize |
| Document everything | Evidence lets the SQE close the file instead of escalating |
How does IDS help suppliers stay off Controlled Shipping?
IDS keeps a resident presence at Stellantis Toluca so the first two habits are covered every working day: alerts answered in person within the hour, and 8Ds driven to a verified close. During launches, preventive GP-12 containment catches early defects before they escape. And when a concern does appear, containment crews are on site within 4 hours, so it is handled and documented rather than left to escalate. That is the core of the containment and Controlled Shipping service. Worried about escalation? Request a quote.
FAQ Frequently asked questions
Can Controlled Shipping really be prevented?
Mostly, yes. It is usually triggered by a repeat escape, not a single defect. Fast response, verified 8D closure and preventive containment at launch remove the repeats that cause escalation.
What is the difference between CSL1 and CSL2?
CSL1 is run by the supplier; CSL2 adds an independent third party at the supplier's cost. See our guide on CSL1 vs CSL2 for the full breakdown.
How does IDS lower our escalation risk at Toluca?
With a resident Quality Liaison who answers the SQE within the hour, drives 8Ds to closure, and dispatches containment crews within 4 hours, so concerns are managed before they formalize.
