The importance of an inspection grows as your business expands. You need to make sure every order meets your requirements.


Preventing Defects

Defects can hurt your business. They can lead to unhappy customers and lost sales. You need to find defects before your products leave the factory. Quality inspections help you do this. You can check for defects in size, color, function, and packaging. Marsky uses detailed checklists to look for defects at every stage.

  • You can use tests like barcode scans and carton drop tests to find hidden defects.

  • You can also check the appearance and function of each item.

Quality assurance means you look for defects and fix them fast. This keeps your products safe and reliable. You can use inspection service tools to track and report defects. This helps you improve your process over time.


Types of Quality Control Inspections

You need to know the main types of quality control inspection. This helps keep your products safe and reliable. Each step lets you find problems early. It also helps protect your brand. Marsky gives you different types of quality control inspections for your needs.


Pre-Production

You begin with a pre-production inspection, called PPI. This step checks raw materials and parts before making products. You make sure the materials meet your quality standards. If you find problems now, you can fix them early. This saves time and money. This is an important part of incoming quality control. Electronics, clothes, and home goods all need this early check.


During Production

Next, you use in-process quality control. Marsky calls this Initial Production Inspection (IPI) and During Production Inspection (DPI). You check products when 10% to 80% of the order is done. You look for defects and make sure the line follows your rules. Random inspection at this stage helps you find problems early. You can change the process and stop delays. This step is important for electronics and soft goods.


Pre-Shipment

You need a last random inspection before shipping. Marsky’s Pre-Shipment Inspection (PSI) checks if finished goods match your order. The team uses random inspection to pick samples. They check how many items, packaging, and product quality. They also test function, safety, and looks. The main goal is to make sure you get what you ordered. The final inspection report shows if the shipment passes or fails. This step in the quality control process protects your name and stops bad goods from reaching your customers.

Tip: Always ask for a detailed final random inspection report. It helps you decide if you should accept or reject the shipment.


Container Loading

The last step is container loading supervision (CLS). You want to make sure the right products and amounts go into the container. The team checks carton conditions, packaging, and labels. They watch the loading and seal the container. They write down everything and give you a report with photos. This random inspection lowers the risk of damage or missing items during shipping. You feel better knowing your goods are safe.


Types of quality inspections like these help you control every part of your supply chain. You use random inspection and final random inspection to keep your quality high. Marsky’s quality control inspection services cover electronics, clothes, and many other products. You can trust their quality control processes to give good results.


Preparation Steps

You must get ready before you start an inspection. Good preparation helps you follow each step. It also helps you reach your quality goals. Marsky uses a checklist that works well. You can use these steps to make sure your plan covers everything important.


Define Criteria

First, set clear inspection criteria. Every inspector should check the same things. This way, you get the same results each time. Use a master checklist template for your product. It should list size, weight, color, and function. If you check home appliances or clothes, add voltage, fabric type, or stitching. Attach instructions and example pictures to your checklist. This helps everyone know what to look for. It keeps your plan on track. Ask inspectors to take photos if something is not clear. This gives feedback and helps you get better. Train your team to use the same methods. They should always check the specifications and compliance standards.

Tip: Make sure your inspection plan matches your quality goals and industry rules. This helps you follow the rules and make fewer mistakes.


Assemble Team

Pick the right people for your inspection team. Each person should know the product and the plan. Your team needs to understand the rules and standards. Marsky says you should train your team. This way, everyone does the steps the same way. Good training makes your results better.


Gather Tools

Get all the tools you need before you start. Use measuring devices, barcode scanners, and safety test tools. Make sure you have the newest checklists and guides. For electronics or clothes, you may need special tools. The right tools help you check specifications and compliance. Having tools ready is very important.


Plan Inspection

Make a detailed inspection plan that fits your needs. Think about the supplier’s history, product value, and safety risks. Some products need more checks if they have many parts or strict rules. Use your plan to set the schedule and give out tasks. Track your progress as you go. Make sure your plan covers all points. Update your plan often if rules or designs change.

Note: Marsky’s plan checks quantity, packaging, looks, and function. This helps you meet all rules and quality needs.


Quality Inspection Steps

Quality Inspection Steps

A good quality control inspection has clear steps. You need to check each part to make sure your products are right. Marsky uses a trusted inspection process. They check things like quantity, looks, and how things work. Let’s see what happens in each step of the quality inspection.


Sampling

You begin with sampling. You cannot look at every item in a big order. So, you pick a few items that show what the whole batch is like. This step helps make the inspection fair and correct.

  • Simple random sampling means every item can be picked. This way, you do not favor any item.

  • Stratified sampling is good when your products have different groups. You split the batch into groups and pick from each group. This lets you check all types, like different sizes or colors.

  • Non-probability methods like quota or purposive sampling are for special cases. But these can make the results unfair.

  • Always watch out for mistakes in sampling and pick the right number of items. This helps you trust your results.

Marsky uses the acceptance quality level (AQL) standard to decide how many items to check. This makes sure the random inspection checks enough products to find problems.


Visual Checks

Next, you do visual checks. You look at how the product and packaging look. You compare each item to your rules. You check color, shape, and surface finish. For example, you might look for scratches or stains on household items. You also check labels, logos, and shipping marks.


Marsky’s inspectors use a checklist so they do not miss anything. They look for problems like color changes, wrong prints, or broken boxes. You can use a color test to see if the product matches your sample. If you find a problem, you take pictures and write it down for your report.

Tip: Always look at the box and packaging in this step. Good packaging keeps your products safe when shipping.


Measurements & Tests

You need to measure and test your products to make sure they are right. Use tools like rulers, calipers, and scales. For machines, you check size, weight, and shape. For clothes, you measure fabric and stitching.

Marsky’s team does tests like:

  • Barcode scan test: You scan the barcode to see if it matches your records.

  • Carton drop test: You drop the box from a set height to check if the packaging protects the product.

  • Color test: You compare the product color to your standard.

These tests help you see if the product passes your quality check. You write down all results in your inspection report.


Function & Safety Tests

You must check if your product works right. This is important for electronics, toys, and home appliances. You test buttons, switches, and moving parts. For example, you turn on a light or run a blender to see if it works.


Safety tests keep your customers safe. You look for sharp edges, loose parts, or electric dangers. Marsky’s inspectors follow strict safety rules. They use special tools to check for risks. If you find a problem, you mark it as a defect and report it right away.

Note: Always follow the last quality control steps for products with strict safety rules. This keeps your customers safe and your brand strong.


Defect Identification

You need to find and write down all defects during your quality control inspection. Defects can be minor, major, or critical. Each type helps you decide if you should accept or reject the shipment.

Here is a table showing common defect types in different industries:

A full quality control inspection checks every detail. You follow these steps to keep your brand safe and give your customers good, safe products.


Documentation & Reporting

Clear documentation and reporting help you keep control over your quality inspection process. You need to record every detail, create useful reports, and share results with your team. This step makes sure you meet compliance rules and keep your products safe.


Record Findings

You start by writing down everything you see during the inspection. Use a checklist to track each item. For example, you can note the size, color, and function of electronics or household products. Take photos of any problems. Write down the results of each test, such as barcode scans or carton drop tests. If you find any issues, you must report defects right away. Good records help you prove that you followed the right steps and met compliance standards.

Tip: Use digital tools or an inspection report template to make your notes clear and easy to read.


Create Reports

After you finish the inspection, you need to make a report. This report should include all your findings, photos, and test results. Marsky uses a final inspection report to show if the products meet your quality standards. The report lists every check, from packaging to function. It also shows if the products pass or fail compliance checks. You can use this report to decide if you should accept the shipment. A good report helps you track trends and improve your quality control over time.

  • Include these parts in your report:

    • Product details

    • Inspection date and location

    • List of tests and results

    • Photos of defects

    • Comments on compliance

Always follow up on any issues to make sure they get fixed before shipping.

Note: Sharing results quickly helps you avoid delays and keeps your customers happy.
