How to Prevent Quality Defects in products by Clarifying Requirements?

How can I prevent quality defects in my products? This is one of the top concerns of most of the importers that are manufacturing in Vietnam, China, India and elsewhere in the Asian countries. In addition to this, making your product needs clear to the supplier is certainly a helpful and cost-effective way to approach limiting product defects. There are many importers who have lost their money due to unsellable products and customer returns simply because their suppliers did not clearly comprehend the expectations before manufacturing & shipping their goods.




But do you know how to make sure that the supplier fully understands your expectations for the product? Usually, experienced importers comprehend that suppliers don’t aim to “make a prompt profit” by selling their substandard goods at the lowest possible cost. Most of the suppliers want to offer their customers with a product that meets their specifications closely so that they can keep their business as profitable as possible. There are a plethora of ways to clarify your need in order to help you get the product you want while reducing defects.


How to Address quality defects in the QC list


The QC checklist is the most crucial document in order to ensure your supplier and any of your staff who inspect your product meet your expectations. An effective checklist for factory and QC staff offers your inspection and requirements criteria for product performance, appearance, and functionality. An insufficient checklist puts you at a higher risk of receiving defective products. In addition to this, it can hinder the ability of the quality analysts to apply your standards when evaluating your product.



Most of the inspection companies in Asia usually divide their checklist into four distinct sections, each of these sections cover different aspects of that product and its packaging:


  1. Product requirements


The most crucial section for most of the importers to be included in their checklist is to identify product requirements. These product requirements often include product size, dimensions, weight, color, material, labeling, to name a few. For instance, you can specify “± 1 cm” tolerances for certain clothing measurements or the Pantone color code “337 U” for a part of a toy you make.


  1. Packaging requirements


Almost all the items need packaging while shipping, so most quality control checklists should also meet the requirements of packing. The well-defined requirements section of packaging ensures that the necessary information and documents will be displayed on the shipping boxes during the import and export process. The clear packaging requirements section also minimizes damage during the entire shipment process and ensure the goods arrive at your hands in the best possible condition they left the factory.


  1. On-site product tests and checks


Section 3 of the QC checklist identifies the necessary product tests and it also verifies that the inspector has performed the website. In addition to this, product tests help to make sure that the product complies with any safety, performance, or job standards or claims. This section will also vary greatly between different types of product- from the strength of the blade test for ceramic knives to the hi-pot test for any electrical appliances.


  1. Classification of defect


The QC checklist should also specify how the supplier and QC team of on-site inspection should take into account and report the product deficiencies found during the entire inspection process. In the quality control industry, these defects in the product are usually classified into 3 types of “major”, “critical”, and “secondary”:



  • The major defect affects the performance of your product adversely or is likely to result in returning the product.
  • A serious defect makes the element unusable or dangerous to the end consumer.
  • A minor defect is usually a minor issue, often related to the product appearance, and does not affect the shape or function of the element.
