An Industry-Leading NSN and Aviation Parts Sourcing Platform
At NSN Sourcing, owned and operated by ASAP Semiconductor, our goal is to make the parts procurement process as quick and efficient as possible. We know how hard and time-consuming it can be to find all the parts and components you need, especially NSNs and obsolete part numbers. As such, we have designed this new purchasing platform to be easy to navigate and enable you to locate the parts you require, with search engines that can browse by part number, description, NSN, manufacturer, CAGE code, and more.
Our inventory of more than 2 billion parts, new and obsolete, is sourced from over 5000 industry-leading manufacturers for the marine, aviation, and IT hardware sectors. As an AS9120B, ISO 9001:2015, and FAA AC 0056B accredited member of the Aviation Suppliers Association (ASA), our customers know that all of our parts are 100% quality assured, and we are the only independent distributor with a No China Sourcing policy to further ensure the integrity of the products we sell.
In addition to having a vast and comprehensive inventory, we at NSN Sourcing also offer the most competitive quotes on the market, the fastest lead times and shipping times, and the strictest quality assurance standards possible. Our team of dedicated account managers work hand-in-hand with our customers, guiding them through the purchasing process and help them overcome even the most challenging of procurement issues.
