About Us

Any Part, Any Time

Stacked Purchasing is owned and operated by ASAP Semiconductor, a leading aerospace distributor. Our inventory contains over 6 billion new and obsolete parts available for immediate purchase, and we specialize in helping source hard-to-find components for our customers. We offer you access to this inventory alongside a powerful search engine and a user-friendly quotation system.

Never Sacrificing Quality

One of the primary values that Stacked Purchasing was built upon is the idea that customers should never need to question the quality of the components they purchase or the trustworthiness of their supplier. As a testament to that belief, we have built a quality assurance program that meets and exceeds industry standards. Our practices and procedures have allowed us to proudly operate with AS9120B, ISO 9001:2015, and FAA AC 00-56B certification and accreditation.

Supply chain

We maintain one of the most robust and efficient supply chains in the industry, and as such, we are able to offer our customers lower prices and expedited shipping times. Our account managers work with every customer to determine their required time frame, and we consistently meet it. Furthermore, our 24/7x365 AOG services are available to get you back in the air with same-day and next-day shipping on select in-stock items.
