Key Takeaways:
- Accreditation Is Fragile: Nadcap is process-specific and lost quickly when non-conformances go uncorrected or audit cycles slip.
- Supplier Risk Is Program Risk: One plater losing accreditation can halt a qualified production line and force costly requalification.
- Consolidation Reduces Exposure: A single, well-capitalized provider maintaining accreditation across facilities lowers procurement risk.
A supplier that holds Nadcap accreditation today is not guaranteed to hold it tomorrow, and when accreditation lapses mid-program, the fallout lands squarely on procurement teams who trusted that status as proof of reliability. Compliance is not a one-time achievement; it is an ongoing obligation that some suppliers fail to sustain under production pressure, staff turnover, or process drift. For procurement teams sourcing plating services, understanding why platers lose accreditation is as important as confirming they have it in the first place.
Valence Surface Technologies, the world’s largest independent aerospace surface finishing company, maintains Nadcap accreditation across its network through the process discipline and quality systems that regulated industries demand.
In this piece, we will cover the common causes of Nadcap accreditation loss, the supplier risks procurement teams should watch for, and how to vet suppliers for long-term stability.
What Is Nadcap Plating Accreditation And Why Does It Matter?
Nadcap plating accreditation is a process-level approval that confirms a supplier’s special processes meet industry-consensus aerospace standards. It is not a company-wide quality certification, it accredits how specific processes are performed. Plating is generally covered under Nadcap Chemical Processing rather than as a standalone universal category.
Who Administers It
Nadcap is an industry-managed approach to conformity assessment of “special processes” that brings together technical experts from prime contractors, suppliers, and government representatives to establish requirements using a standardized approach.
The Performance Review Institute administers the program, scheduling audits and assigning approved auditors who conduct the audit against an industry-agreed standard using an industry-agreed checklist.
Why Primes Require It
Many leading aerospace, defense, and space companies require Nadcap accreditation for specified special processes, depending on contract and flow-down requirements. Because the supplier is Nadcap-recognized, the customer can eliminate or replace the costly individual audits their quality department would otherwise demand, historically primes sent out personnel to audit suppliers directly.
Common Compliance Failures That Lead To Nadcap Accreditation Loss
Accreditation loss rarely comes from a single dramatic failure. It accumulates from unresolved findings, weak process control, and lapsed discipline.
Uncorrected Non-Conformances
Any non-conformances identified during the audit must be addressed before accreditation is granted. Failure to adequately respond to nonconformances can delay accreditation, affect merit status, or jeopardize continued accreditation.
Process Control Breakdowns
These are extensive process-driven audits that require discipline and intense attention to detail from contract review through product shipment, demanding a constant commitment to training and improvement. Poor chemical control, inadequate records, or untrained staff surface fast under Nadcap scrutiny.
Voluntary Withdrawal
Some suppliers simply stop. Some suppliers choose not to pursue or maintain Nadcap accreditation, either by declining audits after initial accreditation or by never becoming accredited in the first place.
How Nadcap Supplier Risk Affects Aerospace Procurement Decisions
Nadcap supplier risk directly shapes sourcing strategy because an unstable plater can disqualify an entire production line overnight.
Cost and Capacity Trade-Offs
The best plating houses maintain Nadcap accreditation, a critical requirement for many aerospace and defense customers, and upholding it is costly, so accredited platers charge higher prices. Procurement teams weigh that premium against the far greater cost of accreditation loss mid-program.
Consolidation Value
Nadcap recognition lets buyers reduce their own audit burden, so a stable, multi-process supplier compounds that efficiency and shrinks the vendor list that must be monitored.
Warning Signs Procurement Teams Should Watch For In Nadcap Suppliers
The clearest warning signs appear in audit history, corrective-action behavior, and financial capacity.
Audit and Merit Red Flags
Loss of merit status is an early signal. To achieve an 18-month merit, a supplier must have passed at least one previous audit with no major findings in the previous and current audit. A supplier slipping back to a 12-month cycle warrants scrutiny.
Undercapitalization
Fragmented, undercapitalized providers struggle to fund the ongoing training, environmental controls, and technology that Nadcap demands, raising the odds of a failed reaccreditation.
What Happens To A Program When A Supplier Loses Accreditation
When a plater loses accreditation, the affected process may no longer be valid for aerospace work under affected customer requirements.
Immediate Impact
Because Nadcap accreditation is only valid for specific company processes, if a required Nadcap accreditation lapses or is withdrawn, the supplier may no longer be approved for that process under affected customer requirements, and parts processed during nonapproved periods may require customer disposition or requalification.
Downstream Cost
Requalifying a new plater consumes months, disrupts on-time delivery, and exposes the prime to compliance gaps until a replacement is fully approved.
How To Vet Suppliers For Long-Term Nadcap Accreditation Stability
Confirming a supplier holds Nadcap accreditation today is not enough, procurement teams need to assess whether that accreditation is likely to hold up over the life of a program. Here is what to evaluate before committing to a plating supplier:
- Audit History and Findings: Review past audit reports for recurring findings, corrective action patterns, and how quickly issues were resolved. A history of repeat findings signals weaker process discipline than a clean or improving audit trend.
- Scope of Accreditation: Verify the specific processes, chemistries, and specifications covered under the supplier’s accreditation. Accreditation for one process does not guarantee coverage for another.
- Quality Management System Maturity: Confirm the supplier operates under AS9100 or an equivalent aerospace quality management system, with documented procedures that go beyond minimum Nadcap requirements.
- Process Control Investment: Ask about bath chemistry monitoring frequency, equipment calibration schedules, and whether process parameters are tracked manually or through automated systems. Manual tracking increases the risk of drift going unnoticed.
- Workforce Stability and Training: High staff turnover in critical quality and process roles often precedes accreditation issues. Ask about training programs, certification requirements, and staff retention in key positions.
- Customer References and Program History: Speak with other aerospace customers about the supplier’s consistency across multi-year programs, not just initial qualification results.
Suppliers who welcome this level of scrutiny and provide transparent documentation are typically the ones with the process maturity to sustain accreditation long term.

Final Thoughts
Nadcap plating accreditation is earned continuously, not once. The suppliers that lose it are usually the ones that let corrective actions lapse, underinvest in process control, or spread risk across fragmented vendors. For procurement teams, the safeguard is a consolidated, well-capitalized partner that holds accreditation across every process your program depends on.
Frequently Asked Questions About Why Nadcap Platers Lose Accreditation
How much does it cost to get Nadcap certified?
Costs vary by operation size and process count. The cost depends on the size and complexity of the supplier’s operations and the number of processes accredited, including audit fees, travel expenses, and certification fees.
What is the difference between Nadcap and AS9100?
AS9100 certifies your company-wide quality system, while Nadcap accredits specific special processes. AS9100 demonstrates structured quality management, while Nadcap proves critical manufacturing processes are performed to the highest industry standards.
Is Nadcap certification mandatory?
Not by law, but effectively yes for many aerospace suppliers. Many leading aerospace, defense, and space companies require Nadcap accreditation for specified special processes, depending on contract and flow-down requirements.
How often are Nadcap audits required?
Merit allows Nadcap-accredited suppliers to reduce audit frequency to every 18 months or, with certain criteria, every 24 months, otherwise the cycle is typically annual/.
What are the benefits of Nadcap certification?
It signals prime confidence and reduces duplicate audits. The program lets suppliers gain tighter control within special processes and provides a forum for a voice in audit requirements, networking, and market recognition.
How long does it take to get Nadcap certification?
First-time accreditation can take several months and commonly extends toward 6–12 months depending on readiness, scope, audit scheduling, and corrective-action closure.
