Years ago several different organizations in the preowned mobile space independently observed a problem: The secondary market for these trade-in, returned, and unsold mobile devices lacked a standardized grading system, leading to disputes and mistrust between buyers and sellers, and, ultimately, wasted time and money. When CTIA Certification(™) announced an initiative to create an industry-wide standard for preowned device grading, leaders from all corners of the mobile market got on board.

When this team of industry experts—including B-Stock—came together to create and evangelize a voluntary grading standard for the mobile device secondary market, the results were clear.

Download our case study on this continued effort if you’re interested in seeing exactly how B-Stock’s support of this new standard led to several great outcomes for our clients, including slower device depreciation, increased bidder interest, and a significant decrease in disputes over listing accuracy and device condition.
