A sourcing agent or trading company can be of great benefit when it comes to finding the right manufacturer. This expertise is extremely desirable in the area of culture, language and negotiating methods. In most cases, however, they are not QC inspectors, or have other interests. For example, because they get a commission if they bring in new customers. So make sure you are not ‘marking your own paper’. An independent third party with good inspectors, such as Quality Control, is needed for a professional inspection.
