Pre-shipment Inspection (PSI)

Pre-shipment inspectionIntroduction

Pre-shipment inspection (PSI), an essential part of quality control, plays a pivotal role in maintaining brand image and ensuring customer satisfaction. It is a product quality check conducted when an order is at least 80% complete. This article delves into the importance, benefits, and process of PSI, with a special focus on Amazon FBA sellers.

Understanding Pre-shipment Inspection

PSI is a systematic procedure that checks the quality of products before they are shipped. It relies on the internationally recognized ANSI/ASQCZ1.4 (ISO 2859-1) statistical sampling procedure to ensure that the product meets the required quality standards. This involves carrying out a random sample check on an AQL sample chart and verifying the overall quality performance, including functionality, appearance, weight, size, and readiness for shipping. A third-party inspection company usually conducts this inspection and issues a complete report to help the client make the final decision on the shipment release. QIS provides a comprehensive guide on understanding PSI.

Benefits of Pre-shipment Inspection

The benefits of conducting a PSI are manifold:

  • It helps avoid wrong or missed product shipping.
  • It prevents the release of poor quality products, thereby avoiding rework or return.
  • It eliminates possible troubles before, not after, shipment.
  • It saves money by reducing extra unnecessary after-sale work.
  • It enhances brand reputation and customer reviews.

Importance of Pre-shipment Inspection for Amazon FBA Sellers

For Amazon FBA sellers, PSI is particularly crucial. Not conducting a PSI can pose high risks, such as supply-chain bottlenecks and unsatisfied customers. PSI helps avoid these issues by ensuring that the product quality is up to the mark before it is shipped.
