What Is Incoming Inspection (Receiving Inspection)?
Also known as: receiving inspection, incoming quality control, IQC, goods receipt inspection
Definition
Incoming inspection, also called receiving inspection or IQC, verifies purchased material against the purchase order, drawing and specification before it is released to stock or production. Checks include documents, count, visual, dimensional and sometimes lab testing.
Incoming Inspection (Receiving Inspection) Explained
The stages are usually document review (PO match, packing slip, CoC and material certifications), identification and quantity check, visual and packaging inspection, then dimensional, functional or lab testing according to an inspection plan. The plan depends on risk: part criticality, supplier rating, history and customer requirements. Results are recorded against the lot, and the lot is accepted, rejected or sent to the MRB.
Inspection effort is usually risk-based. New suppliers and critical characteristics get a full or tightened plan, proven suppliers move to reduced sampling, skip-lot or dock-to-stock under a supplier quality agreement. Switching rules from ANSI Z1.4 formalise this. Special processes and raw material often rely on third party lab certification plus periodic verification testing, and electronic parts in defense supply chains add counterfeit-avoidance checks under AS5553 and related standards.
ERPs implement it as a receipt step. Material is received into a receiving or inspection location (not available stock), an inspection record is generated from the item or supplier plan, and passing the inspection moves stock to available. Infor SyteLine supports receiving inspection with inspection plans and quarantine, and Infor LN uses inspection orders and warehouse inspection locations. The key control is that uninspected material is invisible to MRP and picking.
Pain points include inspection backlogs holding production, inspectors with paper checklists, and supplier data that is never fed back. Capturing measurements electronically at the dock links them to the supplier scorecard, so rejection rate, on time delivery and corrective action responsiveness are measured by the same system.
Why It Matters
- Catching a defect at receipt costs far less than finding it in assembly, final test or at the customer.
- Quarantine until inspection keeps unverified material out of kits and jobs, protecting traceability.
- Inspection data drives supplier scorecards, tightened inspection rules and corrective action requests.
- Standards such as ISO 9001 clause 8.4 and AS9100 require verification of purchased product, and receipt records are the evidence.
In Practice
A 20 pallet delivery of sheet metal arrives. Receiving checks the PO and CoC, then pulls 5 sheets per heat lot to measure thickness and flatness against the inspection plan. Two sheets from one heat are 0.15 mm under minimum. The ERP puts that heat on hold, the other heat lots release to stock, and the supplier gets a corrective action request with the measurements attached.
Frequently Asked Questions
What is the difference between incoming inspection and first article inspection?
Incoming inspection checks each delivery of purchased material. A first article inspection fully verifies the first production piece of a new or changed part against every drawing requirement.
What is dock-to-stock?
A practice where trusted suppliers' deliveries go straight to stock without inspection, based on their quality record and agreements, usually with periodic audits.
Should every delivery be 100 percent inspected?
Rarely. Most plans use risk-based sampling, with tighter checks for critical characteristics and new or poorly rated suppliers.
How does the ERP handle uninspected material?
It is received into an inspection or quarantine location and excluded from available inventory until the inspection result releases it.
Related Terms
AQL and Acceptance Sampling
Acceptance sampling inspects a random sample from a lot and accepts or rejects the whole lot based on the number of defects found. AQL (acceptance quality limit) is the worst defect rate considered acceptable as a process average in that plan.
Certificate of Conformance (CoC)
A certificate of conformance (CoC) is a document from the manufacturer or supplier, signed by an authorised person, stating that delivered goods or services meet the purchase order, drawing and specification requirements, with traceable lot or serial references.
Non-Conformance Report (NCR)
A non-conformance report (NCR) is the formal record that a part, material, process or document failed a specified requirement. It captures what failed, how many, where, and the disposition decision (use as is, rework, repair, scrap or return to supplier).
Traceability
Traceability is the ability to follow the history, location, and application of a part or material through the supply chain and production process, both backward to its sources and forward to every product and customer it reached.
Three-Way Match
A three-way match is the accounts payable control that compares the purchase order, the goods receipt, and the supplier invoice on quantity and price before releasing payment, ensuring a company pays only for what it ordered and actually received.
