What are the most common audit findings in CoC certification?

The most frequently raised non-conformities in CoC audits are: (1) Incomplete sales documentation — invoices missing certification claim or certificate number; (2) Inadequate training records — staff cannot demonstrate understanding of CoC procedures; (3) Physical separation failures — certified and non-certified timber not clearly segregated in storage; (4) Incorrect percentage calculations — errors in volume credit or percentage-based claims; (5) Supplier certificate verification — not checking supplier certificates are valid before purchasing; (6) Outsourcing without control — subcontractors (transport, treatment) not covered by CoC system; (7) Annual volume summary errors — discrepancies between input and output volumes; (8) Logo use violations — incorrect use of FSC/PEFC trademarks on marketing materials.
