font-size: 13pt;\">Three types of issues can lead to inspection failure and possible rejection of shipment by the buyer.<\/span><\/p>\n<h4><strong><span style=\"font-family: roboto; font-size: 13pt;\">1. Conformity to Specifications.<\/span><\/strong><\/h4>\n<p><span style=\"font-family: roboto; font-size: 13pt;\">All relevant aspects of the product are verified: quantity, components, assembly, aesthetics, function, dimensions, labeling, packaging, etc.<\/span><\/p>\n<p><span style=\"font-family: roboto; font-size: 13pt;\">Ideally, the buyer provides a document listing all specifications, which serves as a checklist for the inspector. If no such document is provided, the inspector collects data for the buyer&#8217;s review.<\/span><\/p>\n<h4><strong><span style=\"font-family: roboto; font-size: 13pt;\">2. Number of Cosmetic Defects.<\/span><\/strong><\/h4>\n<p><span style=\"font-family: roboto; font-size: 13pt;\">Based on the sampling plan, the inspector randomly selects a predetermined number of products, inspects them, counts defects, and compares them to the AQL limits.<\/span><\/p>\n<h4><strong><span style=\"font-family: roboto; font-size: 13pt;\">3. On-site Testing.<\/span><\/strong><\/h4>\n<p><span style=\"font-family: roboto; font-size: 13pt;\">Specific tests are conducted depending on the product. For example, a drop test may involve dropping three samples from an 80cm height onto a concrete floor (test fails if at least one sample breaks or malfunctions).<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><strong><span style=\"font-family: roboto; font-size: 16pt;\">What is the Random Inspection Limitation?<\/span><\/strong><\/h3>\n<ul style=\"list-style-type: square;\">\n<li><strong><span style=\"font-family: roboto; font-size: 13pt;\">Suppliers May Resist<\/span><\/strong><\/li>\n<\/ul>\n<p><span style=\"font-family: roboto; font-size: 13pt;\">Importers often place significant pressure on suppliers, who may face price renegotiations or order cancellations if serious quality issues are found.
