In international trade, supply chain security is more than a safeguard—it is a requirement for uninterrupted operations. Under the Customs Trade Partnership Against Terrorism (CTPAT), physical security plays a critical role in ensuring that facilities, cargo, and transport systems remain protected from external and internal threats.
During a CTPAT audit, inspectors assess how effectively a business has implemented physical security measures across facilities, transportation, and storage points. These evaluations provide an objective view of whether a company is aligned with CTPAT compliance requirements and broader global supply chain security expectations.
This article explores what inspectors focus on when reviewing physical security during a CTPAT audit.
1. Perimeter Security and Facility Access
Inspectors review how businesses control access to critical areas. This includes:
Strong perimeter security helps prevent unauthorized entry and reduces the risk of theft, smuggling, or tampering.
2. Cargo Security and Container Integrity
Cargo security is a major component of supply chain management under CTPAT. Inspectors check whether:
Independent supply chain audits ensure these processes are documented and aligned with recognized standards.
3. Surveillance and Monitoring
Inspectors assess the adequacy of surveillance systems, such as:
Auditors verify whether surveillance tools are regularly tested and maintained. Continuous monitoring supports CTPAT compliance and adds another layer to supply chain security.
4. Interior Security Controls
Within the facility, inspectors evaluate:
These controls help minimize vulnerability assessments related to insider threats or procedural gaps.
5. Workforce Security and Training
While physical infrastructure is essential, inspectors also check whether employees are aware of their role in maintaining supply chain security. Areas reviewed include:
Well-trained teams reduce risks by supporting compliance and ensuring security procedures are followed consistently.
6. Documentation and Records
Physical security is not just about structures and technology—it is about how businesses document and maintain security protocols. Inspectors review:
Documentation provides evidence during a CTPAT audit and demonstrates alignment with supply chain management expectations.
Final Thoughts
Physical security is one of the most visible and measurable aspects of CTPAT compliance. From perimeter fencing and container seals to surveillance systems and access control, every measure contributes to a secure supply chain.
At RSJ Inspection, we conduct independent CTPAT audits that provide a clear, unbiased picture of how effectively businesses are implementing physical security measures within their supply chain security framework. These audits ensure transparency and accountability—two essentials for long-term global trade relationships.
