Supplier Corrective Action Request (SCAR) Template — Steel Coil Quality Control

When a coil defect occurs, most buyers send an email:

“This material is not acceptable.”

That is not a corrective action process.

A Supplier Corrective Action Request (SCAR) is a structured document that:

• Identifies the defect

• Links it to measurable evidence

• Requires root cause analysis

• Demands preventive action

• Protects future supply

A SCAR is not an emotional complaint.

It is a formal quality control tool.

This guide explains:

• When to issue a SCAR

• How to structure it

• What evidence to attach

• How to evaluate supplier response

• How to prevent repeat problems

And includes a practical template you can implement immediately.

1. When to Issue a SCAR

A SCAR should be issued when:

• ✔ Measurable non-conformance exists
• ✔ Repeat defect occurs
• ✔ Supplier response inadequate
• ✔ Claim involves financial impact
• ✔ Process failure identified

Do NOT issue SCAR for minor cosmetic issues without measurable deviation.

Overuse weakens credibility.

2. SCAR vs Claim — What’s the Difference?

Claim = Financial resolution request.
SCAR = Quality improvement request.

They may occur together.

But SCAR focuses on:

• Root cause
• Corrective action
• Preventive action

SCAR protects future supply — not just current batch.

3. SCAR Structure Overview

A professional SCAR includes:

1. Supplier details

2. PO reference

3. Coil details

4. Description of non-conformance

5. Evidence

6. Immediate containment action

7. Root cause analysis

8. Corrective action plan

9. Preventive action plan

10. Verification of effectiveness

11. Timeline

Structure prevents vague responses.

4. Practical SCAR Template

Below is a structured format you can adapt.

SECTION 1 — Basic Information

• SCAR Number:
• Date Issued:
• Supplier Name:
• Purchase Order Number:
• Delivery Date:
• Coil Number(s):
• Heat Number(s):

SECTION 2 — Description of Non-Conformance

Describe issue factually:

Example:

“Measured thickness 0.57 mm at multiple locations. PO minimum specified 0.58 mm BMT.”

Include:

• Specification reference
• Measured values
• Inspection method

Avoid emotional language.

SECTION 3 — Evidence Attached

Attach:

• Thickness measurement log
• Photos
• Coating gauge readings
• Adhesion test results
• MTC copy
• Sampling records

Evidence makes SCAR enforceable.

SECTION 4 — Immediate Containment Action

Document what you did:

• Quarantined material
• Stopped production
• Isolated affected stock
• Informed production team

Containment protects your process.

SECTION 5 — Root Cause Analysis (Supplier to Complete)

Supplier must explain:

• What failed?
• Why it failed?
• How it escaped detection?

Encourage structured method:

• 5 Whys
• Fishbone analysis
• Process audit

Vague answers are unacceptable.

SECTION 6 — Corrective Action (Short-Term)

Supplier must define:

Specific action taken to correct issue.

Examples:

• Knife clearance adjustment
• Air knife recalibration
• Coating bath chemistry correction
• Additional inspection step

Must include implementation date.

SECTION 7 — Preventive Action (Long-Term)

Supplier must explain:

How future recurrence will be prevented.

Examples:

• Revised inspection frequency
• New QC checkpoint
• Operator retraining
• Equipment upgrade

Preventive action protects ongoing supply.

SECTION 8 — Verification & Follow-Up

Define:

How corrective action effectiveness will be verified.

Example:

Next 3 shipments subject to enhanced inspection.

Close SCAR only after verification.

5. Evaluation of Supplier Response

Acceptable response:

• Clear root cause
• Specific process failure identified
• Concrete action steps
• Defined timeline

Unacceptable response:

• “Operator error.”
• “Within tolerance.”
• “No issue found.”

Demand evidence-based explanation.

6. Linking SCAR to Financial Resolution

SCAR does not replace:

• Credit note
• Replacement
• Discount agreement

Financial resolution should be documented separately.

SCAR ensures problem does not repeat.

7. SCAR Escalation Strategy

If supplier fails to respond:

• Escalate to management
• Review supplier rating
• Increase inspection frequency
• Consider alternate supplier

Repeat SCARs indicate systemic quality weakness.

8. Common SCAR Mistakes

• Issuing without evidence
• Failing to link to PO tolerance
• Accepting vague root cause
• Closing SCAR too early
• Not tracking repeat defects

SCAR must be controlled process.

9. SCAR Tracking Log (Recommended)

Maintain simple tracking sheet:

• SCAR number
• Supplier
• Issue type
• Date issued
• Response received
• Status
• Closure date
• Repeat occurrence?

This builds supplier performance history.

10. When NOT to Issue SCAR

Do not issue SCAR if:

• Issue is within tolerance
• Damage caused by your storage
• Incorrect handling on-site
• Specification unclear

SCAR must be objective.

11. Benefits of Formal SCAR System

• ✔ Reduces repeat defects
• ✔ Strengthens supplier accountability
• ✔ Improves negotiation leverage
• ✔ Supports audit compliance
• ✔ Protects production stability

Structured suppliers respect structured buyers.

FAQ Section

Is SCAR legally binding?

It supports contractual enforcement but is part of quality process.

Should every claim include SCAR?

Not always.

Yes.

What if supplier ignores SCAR?

Escalate.

Should SCAR reference tolerance?

Always.

Can SCAR affect supplier rating?

Yes.

Should I require timeline?

Yes.

Can SCAR prevent repeat issues?

If properly enforced.

Is verbal complaint enough?

No.

Should SCAR be formal document?

Yes.

Conclusion

A Supplier Corrective Action Request is not just paperwork.

It is:

• A risk management tool
• A supplier accountability system
• A preventive quality strategy

Without SCAR:

Problems repeat.

With SCAR:

You move from reactive claims to controlled quality management.

Professional coil buyers use SCAR not as punishment —

But as structured improvement.

Control the defect.

Control the supplier.

Control the future supply chain.
