An ASAP Logo Semiconductor Web Resource

While Cosmos Purchasing may not have an inventory that rivals the impressive size of its namesake, with more than 2 billion new, used, and obsolete components in our catalogs, our customers will not be disappointed. Included in this inventory is a wide variety of aviation and aerospace parts, IT hardware, electrical supplies, and more, which have all been sourced from trusted entities on our Approved Vendor List (AVL).

We understand how important safety is to our customers, and so we proudly operate with AS9120B, ISO 9001:2015, and FAA AC 00-56B accreditation to prove our commitment to the quality and authenticity of our parts. As part of this practice, we only source from manufacturers who are fully traceable, and we further guarantee the quality of our offerings by carrying out ongoing visual inspections, document verifications, and cross-referencing.

Aside from verifying the quality of our components, Cosmos Purchasing also employs a far-reaching supply chain network that guarantees convenient shipping for all our customers, whether located domestically or across the globe. Coupled with this effort, we are proud to offer competitive pricing that rivals our competitors, using our resources as a distribution partner to negotiate lower prices from top manufacturers.

Once you are ready to look at the diverse range of NSN products we offer, you can easily peruse our online catalog and/or utilize the provided search tool to find specific items and manufacturers of interest.
