Factory Audit Case Studies: China Electronics Sourcing
5 resources tagged with "Factory Audit"
These cases share one habit: a factory audit before the wire transfer, then staged inspections during production. Across them — a 5,000-unit Bluetooth speaker run, 3,000 FCC+CE smartwatches, a private-label Zigbee/Matter sensor — the audit plus a 3-stage inspection regime kept defect rates in the 0.4–0.6% band, well under the AQL thresholds most buyers accept. In the LoRa gateway case the audit started earlier still: tracing a reseller back to its real Shenzhen maker via the public FCC grantee database before any visit.
A factory audit in these projects is not a one-off checkbox — it is the first of several gates, followed by during-production and pre-shipment inspection. The recurring lesson is that auditing the actual manufacturer (not the trading company in front of it) is what unlocks both the cost saving and the quality control.

FAQ
What defect rate is realistic after a proper factory audit and inspection?
In these cases, a factory audit combined with 3-stage inspection produced 0.4–0.6% defect rates on consumer electronics. That's below the typical AQL 2.5 major-defect limit buyers use, but it depends on functional testing, not just cosmetic checks.
Does auditing the factory really save money versus buying through Hong Kong?
Yes — the IIoT gateway and LoRa gateway cases both cut around 22% by auditing and buying direct from the Shenzhen maker instead of a Hong Kong or reseller middleman. The audit is what makes going direct safe.
Can I find the real factory behind a reseller before auditing?
Often, yes. For radio products, the public FCC grantee/ID database lists the actual applicant, which is frequently the real manufacturer rather than the brand selling it. The LoRa gateway case used exactly this to locate and then verify the Shenzhen factory.
