<p>For cosmetic packaging buyers, a useful defect inspection starts with the approved drawing, reference sample and agreed criteria. Record what was observed on the actual bottle-and-pump assembly. Do not treat a generic defect list as a diagnosis of the manufacturing cause or a universal acceptance plan.</p><h2>Identify the Sample and Requirement</h2><p>Record the item, component versions, production lot and inspection stage. Compare dimensions and appearance with the agreed specification and approved samples. Keep photos of relevant observations with their location and sample reference. A defect photograph does not by itself identify the production condition that caused it.</p><figure><img src="https://bamboopackage.com/wp-content/uploads/2026/01/wholesale-white-pet-bottle-bamboo-lotion-pump-front.webp" alt="Lotion bottle and bamboo pump exterior for procurement review" style="max-width:100%;height:auto;"><figcaption>Product appearance example; this photo is not an inspection or performance-test record.</figcaption></figure>
<h2>Separate Observations from Cause and Disposition</h2><div style="overflow-x:auto;margin:24px 0;"><table style="width:100%;min-width:480px;border-collapse:collapse;text-align:left;"><thead style="background:#2d5016;color:#fff;"><tr><th style="padding:12px;">Review area</th><th style="padding:12px;">Procurement record</th></tr></thead><tbody><tr><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Plastic parts</td><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Record incomplete areas, protruding material, depressions or deformation against the specification</td></tr><tr><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Glass body</td><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Record visible cracks, chips, inclusions or dimensional concerns for the responsible quality review</td></tr><tr><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Decoration and exterior</td><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Record scratches, alignment, finish, attachment or color variation</td></tr><tr><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Pump and closure</td><td style="padding:12px;border-bottom:1px solid #e5e7eb;">Record fit, lock movement, priming, output and any leakage under the agreed method</td></tr></tbody></table></div><p>Use the responsible quality team’s handling and disposition process for suspect items. Do not force components or continue destructive checks without an approved method.</p><h2>Agree Severity and Sampling</h2><p>Define defect examples and categories for the actual product. Document the lot definition, inspection method, sample plan and acceptance criteria before inspection. Do not copy a universal AQL percentage, label every leak identically or describe an acceptance limit as a guarantee of zero defects. Confirm who reviews unclear findings.</p>
<h2>Investigate Functional Problems with the Formula</h2><p>Identify the filled product, closure application settings and relevant sample history. Compare affected units with controlled reference assemblies. A fixed number of priming strokes or generic vacuum procedure is not an approval rule for every pump. Ask the supplier to explain a proposed cause and provide evidence for corrective action.</p><h2>Close the Supplier Review</h2><p>Record the affected scope, agreed action, replacement or rework decision, and any follow-up inspection. Retain the approved reference and confirm how future material or tooling changes will be communicated. Do not claim automated, 100% or certified inspection without records supporting the exact scope.</p><p>For a pump complaint, use the <a href="https://bamboopackage.com/why-does-my-lotion-pump-stop-working-and-how-can-i-fix-it/">lotion pump investigation checklist</a>. <a href="https://bamboopackage.com/contact/">Send ECO-BAMBOO the item, lot, photos, sample history and agreed requirement</a> for a project-specific review.</p>
