QC-MAT-002 — Component Purity & Contaminant Acceptance

1. Document Control

2. Purpose

Establish measurable and enforceable purity and contaminant limits for components received for GMP manufacturing use in accordance with 21 CFR Part 111. This specification mitigates the risk of adulterated, contaminated, unsafe, or noncompliant materials entering production.

3. Regulatory Basis

• 21 CFR 111.70(b) — Component specifications
• 21 CFR 111.75(a) — Testing and examination of components
• 21 CFR 111.113 — Material review and disposition
• 21 CFR 111.123(a) — Use of components from qualified suppliers

4. Scope

Applies to all dietary ingredients, excipients, and processing aids received for GMP manufacturing use.

Excludes finished product release testing and in-process material testing.

5. Definitions

Compliant State: All defined attributes meet established limits and documentation is complete and verifiable.

Nonconforming State: Any attribute exceeds defined limit.

Invalid State: Required analytical data missing, unverifiable COA, method not validated, instrument out of calibration, compromised chain-of-custody, or data integrity breach identified.

Reassessment Trigger: Repeated trend shift, supplier performance degradation, regulatory update, or risk reclassification requiring evaluation of established limits.

6. Acceptance Criteria

Compliant State: All listed attributes meet defined limits and documentation is complete.

Nonconforming State: Any listed attribute exceeds established limit.

Invalid State: Analytical record incomplete, unverifiable, method invalid, instrument out of calibration, or data integrity compromised.

Escalation Trigger: Detection of Nonconforming or Invalid State.

Required QMS Process Entry:

• Nonconforming State → Quality Defect Process (SOP-QA-DEFECT)
• Invalid State → Deviation Process (SOP-QA-DEV)

Required Authorization Gate: Final component disposition requires QU authorization per QC-DISP-001.

7. Decision Logic Matrix

8. Exception Handling

• Any result exceeding defined limit constitutes Nonconformance and requires Quality Defect entry.
• Any missing, unverifiable, or compromised data requires Deviation entry.
• Repeated failures or systemic issues require CAPA entry.
• Changes to limits, analytical methods, or risk classification require Change Control entry.
• Final disposition decisions require independent QU authorization.

9. Required Records

• Component Analytical Test Record
• COA Verification Record
• Quality Defect Record (if triggered)
• Deviation Record (if triggered)
• CAPA Record (if triggered)
• Change Control Record (if triggered)
• QU Disposition Authorization Record

10. Authority Classification (E / W / A)

• E — Execution: Sampling, analytical testing, COA verification, and result recording.
• W — Workflow: Entry into Quality Defect, Deviation, CAPA, or Change Control processes.
• A — Authorization: Final component disposition and approval of systemic actions under QU authority.

11. Control State Definitions

Compliant State: All defined purity attributes meet established limits and documentation is complete.

Nonconforming State: Any purity or contaminant attribute exceeds established limit.

Invalid State: Analytical record incomplete, unverifiable, instrument out of calibration, method invalid, chain-of-custody broken, or data integrity breach identified.

Escalation Trigger: Entry into Nonconforming or Invalid State.

Stop-Execution Condition: Material shall not be released or used when in Nonconforming or Invalid State.

Reassessment Trigger: Repeated trend deviation, regulatory update, or supplier performance degradation requiring re-evaluation of established limits.

12. Change Control

Changes to contaminant limits, scope, analytical methods, or risk classification require formal Change Control entry, documented impact assessment, and QU approval prior to implementation.
