During Production Inspection in Asia (including China,
India, Vietnam, Malaysia, Thailand and Bangladesh)


During Production Inspection (DPI), also known as In-Process Inspection, is performed when at least 10% of an order is completed. It can uncover problems at an earlier production stage, allowing more time for rework and correction. It also helps you supervise whether the production process is on schedule.


The inspected samples are selected at random, according to international standards and procedures. V-Trust uses ANSI/ASQ Z1.4-2008 (AQL) as its sampling standard and acceptable level of quality.

When is a suitable time to conduct a During Production Inspection?

A During Production Inspection is normally scheduled when the production is 10%-60% finished.

    Frequently Asked Questions on During Production Inspection

    • Why do I need product inspections?

      If you are worried about or have experienced problems such as poor quality, incorrect shipments, or wrong packaging for goods imported from Asia, product inspection services is your solution. V-Trust product inspection service can help you have accurate understanding about the quality of the goods without going to the factory by yourself.

    • How many days in advance should I book the during production inspection?

      Though sometimes it's possible to book next-day inspections for many manufacturing clusters where V-Trust has a large team of full-time inspectors, we recommend booking with us at least three days in advance. Early booking is important for appropriate scheduling and good preparation before the inspection.

    • Who will I be in contact with throughout the whole process?

      There will be one dedicated account manager who will be assigned as your main contact point at V-Trust. You will receive prompt responses whenever you have any questions regarding the inspection arrangement.

    • Do I need to send you an approved sample?

      It would be great if you can send the approved sample to V-Trust before the inspection for reference. Compared with product photos or specification documents, a real product sample allows V-Trust engineers to do a more thorough comparison check.

    • Do I need to inform the factory about the planned inspection?

      Yes. Your account manager at V-Trust contacts the factory to confirm the actual inspection date before each inspection. If you have informed the factory in advance that you will commission V-Trust to conduct the inspection, this confirmation process will go much more smoothly. Therefore, you can include this message in the purchase order: During or after production, the order shall be inspected by V-Trust Inspection Service (www.v-trust.com).

    • Can I discuss with you in details about my own inspection criteria?

      Absolutely! Though V-Trust has 1600+ checklists for different product categories, we encourage our clients to share whether they have special requirements for the inspections, or issues that they hope the inspector can pay attention to. We can combine them into a tailor-made checklist for inspection reference.

    • How long does it take to know the inspection result?

      The official report, reviewed and signed by an authorized V-Trust technical manager, will be available within 24 hours after each inspection. Same day report is available if you would like to know about the inspection findings on the same day. V-Trust has the highest same day report rate in the inspection industry.

    • What if I have questions after I check my V-Trust report?

      Please don’t hesitate to contact us whenever you have any questions. V-Trust team is always available even after the inspection is completed.

    • What other services can I choose besides during production inspection?

      Besides during production inspection, V-Trust also provides other services like pre-shipment inspection, container loading supervision, factory audit, social compliance audit, laboratory testing, product certification etc.
