During Production Inspection (DUPRO)

What is DUPRO?

A During Production Inspection (DUPRO) — also called DPI — is a third-party quality check done while your order is still being manufactured, typically when about 25% of the goods are finished.

Unlike a receiving (incoming materials) check, DUPRO looks at finished and semi-finished units already on the production line. The goal is to find defects early enough for the factory to correct them before the rest of the order is made — and before a final pre-shipment inspection.

HKQCC’s team of inspectors across China, Vietnam, India and Southeast Asia performs DUPRO for US, UK and EU importers and Amazon sellers. You receive a photo report within 24 hours after the inspection.

When should you book a DUPRO?

Book a During Production Inspection when:

  • Production has reached about 25% finished
  • You want to confirm materials, workmanship and packing match your specs before the whole batch is finished
  • A previous shipment had quality issues and you want earlier oversight
  • Lead time is tight and you cannot wait until a final random inspection

If production has not started, book an Initial Production Check (IPC). If goods are 100% finished and packed, book a Pre-Shipment Inspection / FRI.

Booking lead time: We typically confirm DUPRO bookings about 3 working days ahead. Regular customers can often be scheduled in 1–2 working days, subject to inspector availability near the factory.

What our inspector checks

Exact checklist depends on your product and purchase order. A typical DUPRO covers:

  1. Production status — finished vs still in process; ship-date risk
  2. Workmanship — defects on finished / semi-finished units
  3. Materials and components — vs approved samples / BOM
  4. On-site tests — common on-site tests agreed with you in advance for the product
  5. Packaging and labelling — if packing has started
  6. Quantity progress — units completed vs order quantity

Findings include photos. Defects follow your AQL plan when sampling applies — see AQL sampling.

How the process works

  1. Book — send PO, specs, samples (or photos), packing requirements and preferred date. Allow about 3 working days for confirmation (regulars often 1–2).
  2. Confirm — inspector assignment and factory address in China, Vietnam, India or Southeast Asia.
  3. Inspect — on-site visit on the agreed day.
  4. Report — within 24 hours.
  5. Decide — corrective action while production continues, or adjust the final inspection plan.

FAQ

Q1. What is the difference between DUPRO and a Final Random Inspection?

DUPRO is done while production is still ongoing (typically from about 25% finished). A Final Random Inspection (FRI) is done when goods are finished and preferably packed, to decide whether to ship.

Q2. When is the best time to schedule a DUPRO?

Usually when about 25% of the order is finished.

Q3. Do you offer DUPRO in Vietnam and India as well as China?

Yes — China, Vietnam, India and Southeast Asia.

Q4. How far ahead should I book?

Typically about 3 working days; regular customers often 1–2 working days.

Q5. How soon will I get the report?

Within 24 hours after the inspection.

Q6. Is DUPRO the same as receiving inspection?

No. Receiving inspection checks incoming materials before production. DUPRO checks products already on the line.

Q7. How much does a DUPRO cost?

Contact us for a quote. New customers may ask about 50% off the first 3 inspections (use within 1 month; not factory audit / SA8000).
