A structured supplier audit is your documented evidence of that control. For packaging procurement teams, the audit must go beyond generic quality-system questions: it must interrogate corrugated board performance, film converting tolerances, and regulatory documentation. This checklist is built for on-site or remote audits of corrugated, folding carton, and flexible packaging suppliers in 2026.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Why Packaging Supplier Audits Differ<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Packaging failures are rarely bureaucratic\u2014they are structural. An ECT (Edge Crush Test) shortfall of 10% on a 32 ECT C-flute board can double transit damage rates. Auditors must therefore connect ISO 9001&#8217;s process-control logic (Clause 8.5) to physical test labs, flute specifications, and substrate lot traceability. Regulators add pressure: the EU Packaging and Packaging Waste Regulation (PPWR), fully applicable since August 2026, requires recyclability grading and recycled-content declarations, while US state EPR programs (California SB 54, Oregon, Colorado) demand producer-verified supplier data. A supplier without material compliance documentation is now a supply-chain liability, not just a quality risk.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>The Core ISO 9001 Supplier Audit Checklist<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Use this 12-point checklist, scored 0\u20135 per item for a 100-point weighted qualification (our <a href=\"https:\/\/tadapack.com\/news\/custom-packaging\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">Custom Packaging<\/a> QA teams apply it to every new mill and converter).<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>1.
