4> The client arranges payment for the inspection service several days before the inspection start date and settles the relevant fees.
5> SUNPOR inspectors/auditors perform the work and will provide the client with a detailed and comprehensive report within 24 hours after the inspection is completed.

2. How many days in advance should I book? When should I pay for the inspection? How can I pay for the inspection?A completed booking form along with all relevant order details/inspection requirements must be sent to the SUNPOR office at least 3 working days before the planned inspection date. The earlier you book, the better we can prepare and secure the required inspection schedule.
Our service fees typically require confirmation and payment 4 working days before the inspection date.
You will receive a proforma invoice before the inspection, which can be paid via bank transfer, Alipay, etc.

3. Do you offer monthly payment terms?
For new clients and occasional clients, payment is always required before the inspection date.
For regular and VIP clients who schedule periodic inspections and maintain long-term cooperation with us, monthly payment terms can be discussed. Monthly invoices should be paid within 4 working days after they are issued to the VIP client.

4. What information is included in your inspection report?
Our reports are very detailed and include pictures and charts. The report covers:
1> Summary section (Item, Material, Color)
2> Quantity and Sample Size
3> Workmanship Summary (AQL)
4> List of Workmanship Defects
5> Dimensional Measurements
6> Functional Testing
7> Packaging
8> Shipping Marks (Labels)
9> Important Remarks and Professional Feedback.

5. Why do most of our clients choose Factory Audits or Pre-shipment Inspection services?
A Factory Audit (FA) helps you understand who you are placing an order with. The factory's background, legitimacy, capabilities, QC system, etc., are all examined and presented in the report. It helps you make a final decision on whether to work with the factory and can help avoid scammers posing as legitimate entities.
Pre-shipment Inspection (PSI), also known as Final Random Inspection (FRI), is part of supply chain management and is a crucial and reliable quality control method to verify product quality before you settle the final payment.
To detect production issues early, you can use our During Production Inspection (DPI) service.

6. How many days before the loading/shipment date is it better to conduct a Pre-shipment Inspection?
A Pre-shipment Inspection (PSI) is always conducted when the goods are 100% completed and at least 80% packed in the master cartons (if more than one piece, at least 80% of each item must be packed in master cartons) before the inspector arrives. This is set as the default inspection condition.
Some clients require PSI when the goods are over 80% complete and 80% packed.
Some clients require PSI when the goods are 100% complete and 100% packed.
It is recommended that the pre-shipment inspection be conducted at least 2 days before the loading date. This gives the client time to review the report, and any issues found during the inspection can be resolved by the factory before shipment.

7. How is sampling conducted during the inspection?
SUNPOR uses the well-established and widely adopted international standard ANSI/ASQC Z1.4-2003 (equivalent to MIL-STD-105E, ISO 2859, NF06-022, BS 6001, DIN 40080, and GB 2828) to measure the Acceptable Quality Level (AQL) of the inspected products. This standard and its equivalents are designed based on statistical theory and are indexed by AQL tables. The sampling plans within these standards indicate the number of product units to be inspected from each lot or batch (sample size) and the criteria for determining the acceptability of that lot or batch.

8. What is the coverage area of your inspection services?
Coastal provinces and major manufacturing cities in China.

9. What if a batch fails the quality inspection?
If the quality fails the inspection, the supplier is required to rework the entire batch to rectify the defective products, not just the AQL sample size that was inspected. It is recommended that the client requests a re-inspection after a failed inspection, which reasonably reinforces the factory's understanding of product quality requirements. Re-inspections are typically scheduled several days after the initial failed inspection date.

10. What should I do if non-conforming goods are found upon arrival?
It is extremely rare for defective or unexpectedly substandard goods to leave the factory after being inspected by SUNPOR. In the vast majority of cases, the root cause is damage during transportation, or shipment was approved after a failed inspection based on the buyer's sufficient trust in the factory (which should have reworked the goods) to ship without a re-inspection or defect sorting service.
Therefore, we strongly recommend that you book a re-inspection or defect sorting service after a failed inspection and work with your logistics partner to ensure the products are not damaged during transit.
