IQC and OQC sit at opposite ends of the same shipment. Incoming quality control (IQC) checks goods as they arrive; outgoing quality control (OQC) checks them before they leave. The difference sounds trivial, but in a dispute it is everything — because the question is rarely "were the goods damaged?" It is "where, and on whose watch?"
Understanding the distinction, and why you cannot rely on one without the other, is the foundation of a documentation strategy that actually protects you.
Incoming quality control is the inspection performed when goods arrive at your facility. It confirms that what was received matches what was ordered, and records the condition of those goods at the moment they entered your custody. IQC is your first line of defence against accepting damage you did not cause — and then being held responsible for it.
In practice, IQC is where you document arriving pallets, note any pre-existing damage, and verify quantities against the delivery note. The receiving end of this is the same discipline described in documenting pallet damage at inbound receiving.
Outgoing quality control is the inspection performed before goods leave. It confirms order accuracy, condition, packaging and labelling at the point of dispatch. OQC is your last line of defence — the final chance to catch an error, and the evidence that the shipment left in good order. The full breakdown is in what is OQC.
The two checks differ in timing, purpose and the question they answer. IQC happens on arrival and protects you against inheriting someone else's damage; it answers "what condition did we receive this in?" OQC happens at dispatch and protects you against claims on goods you handled correctly; it answers "what condition did we send this in?"
They also differ in who relies on them. IQC evidence is most useful when dealing with your suppliers and inbound carriers. OQC evidence is most useful when dealing with your customers and outbound carriers. One protects the upstream relationship; the other protects the downstream one.
Documenting only one end leaves a gap a claimant can drive through. If you record outgoing goods but not incoming, you can prove what you shipped but not whether it arrived to you damaged. If you record incoming but not outgoing, you can prove what you received but not what you sent. Only by documenting both do you establish an unbroken record across your entire window of responsibility — the principle of closing the loop between IQC and OQC.
For goods crossing borders or moving by sea, the same logic extends to formal checkpoints. This is why pre-shipment inspection matters for logistics and quality control, and why container loading inspections increasingly rely on photo evidence.
Photos are what make IQC and OQC defensible rather than anecdotal. A written note that goods were "checked and OK" is an opinion. A timestamped image of the actual pallet, tied to the order, is a fact. The same lightweight capture step works at both ends: photograph, attach to the order, move on. The discipline is identical — only the direction changes.
What does IQC stand for?
IQC stands for incoming quality control — the inspection of goods as they arrive at a facility, verifying they match the order and recording their condition on receipt.
What is the difference between IQC and OQC?
IQC inspects incoming goods at arrival; OQC inspects outgoing goods before dispatch. IQC protects you against inheriting damage; OQC protects you against claims on goods you sent correctly.
Do I need both IQC and OQC?
Yes. Documenting only one end leaves a gap. Together they create an unbroken record of condition across the whole period the goods are in your custody.
Is OQC just final inspection by another name?
OQC is the structured, recorded form of final inspection, focused specifically on order accuracy, condition and packaging at dispatch — with evidence attached.
