High-security paper shredders destroy classified, secret, and Controlled Unclassified Information (CUI) documents down to particles small enough to defeat reconstruction. Every unit in this collection is built to the highest DIN 66399 security level, P-7, which calls for micro-cut destruction with a maximum particle size of about 5 square millimeters. That is the standard required for top-secret and classified material, well beyond the cross-cut and strip-cut shredders used for routine office paper.
A P-7 shredder is the right choice when compliance, not convenience, sets the requirement. Government agencies, defense contractors, financial institutions, healthcare organizations, and any operation handling classified or CUI documents rely on NSA/CSS-listed micro-cut destruction to meet their security policies. The micro-cut particle is far finer than what a standard high security paper shredder or general commercial unit produces, which is what separates a true classified document shredder from an ordinary office machine.
Mid-State Litho is an authorized dealer for the leading P-7 shredder brands, Formax and MBM Destroyit. We help you match the right NSA shredder to your throughput and workspace, from a deskside micro-cut shredder to a central-office unit, and we back every machine with service, supplies, and financing.

High-security shredder FAQ
What is a P-7 / high-security shredder?
P-7 is the highest security level in the DIN 66399 standard. A P-7 shredder is a micro-cut machine that reduces documents to particles of roughly 5 square millimeters or less, the level required for classified and top-secret material. This makes it a true high security paper shredder rather than a general office unit.
What is the difference between P-7 and P-5 or P-6?
The number reflects particle size and the classification of material each level is suited to. P-5 and P-6 produce progressively smaller particles for confidential and secret documents, while P-7 produces the smallest particle of all and is intended for the most sensitive classified and CUI material.
Are these NSA/CSS listed?
P-7 micro-cut shredders are the class of machine used for NSA/CSS-listed high-security destruction. Listing is specific to individual evaluated models, so confirm the current NSA/CSS listing for the exact model you need with our team before you order.
Deskside vs central-office high-security shredder - which do I need?
A deskside micro-cut shredder suits an individual secure workstation with lighter volume, while a central-office unit handles shared, higher-volume destruction for a department or facility. Match the machine to your daily volume and how many people will use it.
