Incoming Inspections: Process, Challenges, and Tips (+ Free Report Template)

In manufacturing, the quality of your final product often hinges on the quality of the materials you start with. According to ASQ, the total Cost of Poor Quality (COPQ) can deplete 15% or more of a manufacturer’s annual revenue.

Incoming inspections are the first line of defense. By systematically verifying the quality of raw materials and components upon arrival, you can prevent costly errors, protect your brand reputation, and ensure customer satisfaction.

What are Incoming Inspections?

An incoming inspection is the process of thoroughly assessing the quality of raw materials and components received from vendors before they’re used for further manufacturing processes. It is an essential step in manufacturing QC, which aims to detect and address issues early on, preventing them from affecting further processes.

Why Incoming Goods Inspections are Important in Manufacturing

A thorough incoming inspection process is essential for the following reasons in manufacturing:

• Enhances Quality Control from the Beginning: Quality control in manufacturing should start as early as possible. Incoming material inspections allow businesses to detect and address problems at the raw material stage before incorporating them into the production process.
• Prevents Defective Products from Reaching Customers: When combined with other steps in the manufacturing QC, a thorough incoming goods inspection ensures that the customers only receive high-quality products that meet all the specifications.
• Protects Brand Reputation and Customer Satisfaction: Quality and consistency are the cornerstones of customer satisfaction. By maintaining strict quality standards from the start through inward inspections, you not only create a clientele of satisfied customers but also create a trustworthy and reliable brand. 
• Encourages Continuous Improvement: Incoming inspections provide valuable feedback on the quality of received materials. Businesses can use inspection data to identify trends and areas of improvement and implement corrective actions to address potential issues within the supply chain.
• Helps Meet Quality Standards and Regulations: Incoming goods inspections verify if the received material complies with specific regulations and industry standards necessary for safety and quality.

Incoming Inspection Standards

Let’s look at some key industry standards often used for incoming inspections of received goods.

• ISO 9001: Although not explicitly mentioned, ISO 9001:2015 requires companies to have incoming material inspection procedures to ensure they meet requirements. Explore our complete guide on how to perform effective ISO 9001 audits.
• Industry-specific Standards: Different industries have their own specific standards for incoming inspections. For example, the Automotive Industry Action Group (AIAG) is a popular standard in the automobile industry.
• Military Standards: Incoming inspections within the defense and aerospace sectors are frequently governed by stringent Military Standards (often designated as MIL-STD or MIL-SPEC). They typically mandate highly detailed procedures for verification, testing, sampling methods, and documentation.

Incoming Inspection Process: Steps to Perform Effective Incoming Checks

To ensure that only quality materials enter your production process, it’s critical to follow a structured and thorough incoming inspection procedure. Here’s a step-by-step approach to implementing effective incoming QC inspection procedures.

Step 1: Receipt and Documentation Review

Upon arrival of a shipment, first verify that the items match the order. Inspectors should log the delivery and cross-check all paperwork, including the purchase order, packing list, and any compliance or material certificates, against the physical goods.

Step 2: Visual Inspection

Next, conduct a thorough visual check of the incoming materials​. Key items to examine include:

• Labeling: Verify all labels and markings (part numbers, batch/lot numbers, expiry dates, safety symbols) are correct and legible.
• Packaging Integrity: Look for damage to boxes, seals, or shipping containers – no tears, dents, moisture, or pest activity.
• Cleanliness/Contamination: Check for any foreign debris, rust, oil, or other contaminants inside the packaging or on the parts themselves.

Packaging inspection apps like GoAudits can greatly speed up and standardize this work. For example, a digital checklist can prompt the inspector to take photos of critical issues with packaging and automatically flag any missing labels or damaged seals.

Step 3: Sampling and Detailed Inspection

Based on the shipment size and quality requirements, select a representative sample of units for detailed testing. Follow a pre-defined sampling plan to balance risk and inspection effort. For each sampled unit, perform thorough checks such as:

• Dimensional Checks: Measure critical dimensions and tolerances with calipers or gauges to confirm they meet specifications.
• Functional Tests: Operate or power up the sample parts (if applicable) to verify they work as intended (e.g., fit, form, function tests).
• Material Verification: Where needed, verify material properties – for example, hardness testing, chemical spot tests, or reviewing a material certificate – to ensure the part is made from the correct substance.

Step 4: Laboratory Testing (If Required)

Some components or materials require formal lab verification. Arrange laboratory tests when needed, such as chemical composition analysis for metal alloys, tensile or hardness tests for critical mechanical parts, or microbiological testing for raw materials.

Step 5: Handling Non-Conformances & Supplier Feedback

If any item fails inspection or test, immediately flag it as a non-conforming unit. Segregate the affected shipment and document the issue in detail.

Use a manufacturing inspection app like GoAudits to record each non-conformance with photos and initiate the appropriate escalation (e.g., notify quality management or the supplier). Furthermore, initiate prompt corrective actions (such as returning the batch, applying rework, or requesting a supplier corrective action) within the app.

Step 6: Documentation and Record-Keeping

Maintain detailed records of every inspection, including shipment identifiers, inspection findings, measurement data, reports, and any corrective actions taken. 

Implement checklists for consistent, comprehensive, and accurate incoming goods inspection procedures. Checklists help inspectors stay methodical, avoid overlooking important criteria, and maintain uniform standards across shipments and suppliers.

For the best results, use digital manufacturing checklists. They enable real-time data capture, ensure no checkpoint is overlooked, allow users to capture photo evidence, and provide a standardized inspection scoring.

Common Challenges and Solutions in Incoming Quality Inspections

Even with a solid process in place, incoming material inspections often come with challenges that can impact efficiency and accuracy. Let’s explore some common issues teams face and practical solutions to overcome incoming inspections.

Time-Consuming Process

Managing inspection effectively within tight deadlines using paper checklists or spreadsheets can be cumbersome. Especially on days with a high volume of goods flowing in, staff may spend hours on data entry, filing, and chasing missing documents instead of inspecting goods.

Solution: Implement incoming inspection software to streamline the procedures. With these tools, you can create and automate inspection checklists and make them accessible to workers on the shop floor through their mobile devices. Staff can log inspections and generate instant reports that can be shared with relevant team members, saving valuable time.

Coordination Between Teams

Poor communication between the warehouse, production, quality, and purchasing teams can block prompt corrective actions. Moreover, there needs to be a system that allows manufacturers to keep the vendors in the loop about the inspection findings and the final results.

Solution: A manufacturing inspection tool allows inspectors to generate detailed incoming inspection reports and share them with all the relevant stakeholders instantly. The GoAudits inspection app even allows you to share the reports with external parties like vendors and suppliers. In case of serious discrepancies, inspectors can also issue alerts and notify the management about the findings. They can even initiate corrective actions themselves within the app.

Errors and Lost Records

Manual inspection processes are inherently prone to mistakes. Handwritten notes on nonconformances can be illegible, and operators may skip steps under pressure or forget to record a measurement. In fact, updating paper-based processes can be a high-effort task, often resulting in inaccuracies and errors as well as inconsistent information.​

Solution: Use digital checklists and quality inspection software like GoAudits that enforce consistency and keep all records in a single online repository. Digital checklists guide employees through the entire inspection process, making it impossible for even the smallest inspection step to be forgotten.​ Inspectors can attach photos of defects and add comments, removing the risk of illegible scribbles. Over time, these tools build an audit trail so every finding is recorded clearly.

Need for Continuous Training

Inward inspection standards and product specifications change over time, so inspectors need ongoing training. Without regular refreshers, even experienced inspectors can miss new requirements.

Solution: Hold periodic training sessions and competency checks for inspection staff. Implement updated digital checklists and manufacturing SOPs as on-the-job training aids. Ensure all inspectors have access to the correct and updated procedures, along with any new instructions. Review logged inspection data to identify knowledge gaps and tailor future training.
