About Us

Welcome to Purchasing Union, a state of the art purchasing platform owned and operated by ASAP Semiconductor. We are revolutionizing the parts procurement process, offering customers access to over 2 billion parts with unmatched quality and service. To ensure that you only receive the best, we source our parts from top global manufacturers we trust. Before shipment, each and every item is also subjected to rigorous quality assurance testing, inspection, and cross referencing. Due to our steadfast commitment to such quality control practices and standards, we have established ourselves as an FAA AC 00-56B, AS9120B, and ISO 9001:2015 certified enterprise.

Whether you are in need of parts that cater to aerospace, electronic, civil, or defense applications, we can help you procure all that you need for your operations. We also specialize in tracking down hard-to-find, obsolete, and long lead-time items, offering time and cost savings. If you are facing a time constraint, we provide same day shipping on a number of items utilizing our supply chain network locations stretching across United States.

We invite you to explore our ever expanding catalog at your leisure, and our experts are readily available 24/7x365 to answer any questions and provide competitive prices on all that we carry.
