It identifies which parts of the shipment are a container-wide concern, which products require their own sample or test, and which evidence must remain connected to each SKU and lot.<\/p>\n<p>ASQ defines acceptance sampling as inspecting a sample from a lot to decide whether to accept that lot, and defines a sampling plan as the sample sizes and acceptance or nonacceptance criteria used.[^1] A container is not automatically a single homogeneous lot just because it travels under one bill of lading.<\/p>\n<table>\n<thead>\n<tr>\n<th>Inspection layer<\/th>\n<th>Objetivo<\/th>\n<th>Record needed<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Container-wide<\/td>\n<td>Check seal, condition, load pattern, moisture or damage signs, and document match<\/td>\n<td>Container ID, photos, seal, loading evidence, and packing-list version<\/td>\n<\/tr>\n<tr>\n<td>Carton-level<\/td>\n<td>Check counts, markings, carton condition, and carton-to-SKU identity<\/td>\n<td>Carton number, SKU, lot, quantity, and location in load<\/td>\n<\/tr>\n<tr>\n<td>SKU-level<\/td>\n<td>Check product, function, appearance, labels, pack, and specified features<\/td>\n<td>SKU, revision, lot, sample selection, defect record, and result<\/td>\n<\/tr>\n<tr>\n<td>Lot-level<\/td>\n<td>Keep production or batch evidence separate when relevant<\/td>\n<td>Lot or batch code, source, date, and supporting documents<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"why-is-a-mixed-container-not-automatically-one-lot\">Why is a mixed container not automatically one lot?<\/h2>\n<p>Different SKUs can have different product risks, packing methods, manufacturing dates, suppliers, defect histories, and customer requirements. That is why a <strong>mixed SKU container inspection<\/strong> needs defined risk groups. A small carton of high-value fragile goods can deserve more scrutiny than a large quantity of simple, repeatable accessories, even when both are in the same container.<\/p>\n<table>\n<thead>\n<tr>\n<th>Difference<\/th>\n<th>Why it changes the inspection plan<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Product function<\/td>\n<td>A functional failure can matter more than a cosmetic issue<\/td>\n<\/tr>\n<tr>\n<td>Defect history<\/td>\n<td>A recurring failure needs targeted attention<\/td>\n<\/tr>\n<tr>\n<td>Packaging and labels<\/td>\n<td>A barcode, warning, or retail pack error can affect only one SKU<\/td>\n<\/tr>\n<tr>\n<td>Supplier or site<\/td>\n<td>Output from different sources should not be blended without traceability<\/td>\n<\/tr>\n<tr>\n<td>Lot or date code<\/td>\n<td>A production change may affect one portion of the load<\/td>\n<\/tr>\n<tr>\n<td>Customer requirement<\/td>\n<td>Certain SKUs may have defined tests or evidence requirements<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Microsoft&#8217;s acceptance-sampling <a href=\"https:\/\/sourcingall.com\/es\/services\/\">guidance<\/a> separates lot size, inspection level, AQL index, defect category, sample size, and accept\/reject thresholds.[^2] A <strong>mixed SKU container inspection<\/strong> should define those elements at the relevant SKU or risk-group level rather than assume one setting covers every product.<\/p>\n<h2 id=\"which-skus-should-receive-priority\">Which SKUs should receive priority?<\/h2>\n<p>Prioritize based on documented risk, not preference or a random desire to inspect the most expensive carton.

Different SKUs can have different risks, requirements, quantities, cartons, and defect histories. Define the applicable lot or risk group first.<\/p>\n<h3 id=\"which-skus-should-i-inspect-first\">Which SKUs should I inspect first?<\/h3>\n<p>Prioritize documented product risk, defect history, customer requirements, complexity, fragility, packaging or label risk, value, change status, and traceability.<\/p>\n<h3 id=\"is-the-container-itself-an-inspection-lot\">Is the container itself an inspection lot?<\/h3>\n<p>Not automatically. Acceptance sampling applies to a defined lot. A mixed load can include separate SKU or lot populations that need separate inspection logic.[^1]<\/p>\n<h3 id=\"what-is-a-container-wide-check\">What is a container-wide check?<\/h3>\n<p>It checks conditions that affect the whole shipment, such as container identity, seal, visible damage, packing-list version, carton totals, and load condition.<\/p>\n<h3 id=\"what-must-be-recorded-for-each-selected-sku\">What must be recorded for each selected SKU?<\/h3>\n<p>Record SKU, product revision, lot or batch if applicable, carton source, load location, selected quantity, test method, defect category, result, and evidence.<\/p>\n<h3 id=\"should-i-sample-cartons-from-different-parts-of-the-container\">Should I sample cartons from different parts of the container?<\/h3>\n<p>Where feasible and relevant to the SKU, spread selection across actual carton locations. The report should identify where each selected carton came from.<\/p>\n<h3 id=\"what-if-a-packing-list-does-not-match-carton-labels\">What if a packing list does not match carton labels?<\/h3>\n<p>Stop treating the map as reliable. Document the discrepancy, identify affected SKUs and cartons, and follow the agreed escalation or reconciliation process before release.<\/p>\n<h3 id=\"does-a-passing-inspection-guarantee-every-item-is-correct\">Does a passing inspection guarantee every item is correct?<\/h3>\n<p>No. Sampling supports a lot decision under a stated plan. It does not prove that every unit conforms.[^1]<\/p>\n<h3 id=\"can-this-guide-set-my-aql-or-regulatory-plan\">Can this guide set my AQL or regulatory plan?<\/h3>\n<p>No. It provides general <a href=\"https:\/\/sourcingall.com\/es\/\">abastecimiento<\/a> education.
