At National Stock Number Purchasing, we are a comprehensive source for NSN parts that serve those within the private and commercial sectors. Our inventory of over 2 billion products includes engine components, airframe structures, aviation-grade electrical connectors, and others, those of which have been evaluated for their fit and function on board aircraft and within other industrial applications. Carrying out a rigorous inspection program that frequently includes visual inspection, document verification, and cross-referencing of identifiers, we go the extra step to guarantee the air-worthines of many of our offerings. As such, each order we ship will include manufacturer trace documentation and any applicable quality certifications. Furthermore, our No China Sourcing policy dictates that we source only from trusted and traceable entities on our Approved Vendor List (AVL).
