Not all shredded documents are destroyed to the same level.
Two shredders can both make a document unreadable at a glance while producing dramatically different particle sizes. The smaller the permitted particles become, the more difficult reconstruction generally becomes.
That is where standardized shredding security levels come in.
P-6 shredding is a very high-security paper destruction level under DIN 66399 / ISO/IEC 21964. P-6 permits a maximum particle area of 10 mm², with a maximum strip width of 1 mm for regular particles.
It sits above P-5 and immediately below P-7 within the seven-level paper classification system.
P-6 may be considered when an organization handles particularly sensitive information or has contractual, governmental, internal, or other requirements calling for a very small destruction particle size.
But that does not mean every confidential business document needs P-6 shredding.
The right security level should reflect the sensitivity of the information, applicable requirements, organizational policy, and the consequences of unauthorized disclosure.
Black Ops Destruction provides secure document shredding throughout Ohio and the Midwest using controlled destruction procedures designed to protect confidential information from collection through final destruction.
What Does P-6 Mean?
The "P" classification applies to information presented in its original size, primarily paper and printed documents.
The system includes seven security levels:
- P-1
- P-2
- P-3
- P-4
- P-5
- P-6
- P-7
As the P-level increases, the maximum permitted particle size becomes progressively smaller.
That gives organizations a standardized way to discuss paper destruction rather than relying only on general terms such as:
- Strip-cut
- Cross-cut
- Micro-cut
- Secure shredding
- High-security shredding
Those descriptions can be useful, but the P-level provides a defined technical classification.
What Is the P-6 Shred Size?
P-6 permits paper particles with a maximum area of 10 mm².
For regular particles, the maximum permitted strip width is 1 mm.
That is substantially smaller than the maximum particle area permitted at P-4 or P-5.
For comparison:
- P-4: maximum particle area of 160 mm²
- P-5: maximum particle area of 30 mm²
- P-6: maximum particle area of 10 mm²
- P-7: maximum particle area of 5 mm²
The permitted P-6 particle area is therefore one-third of the P-5 maximum and one-sixteenth of the P-4 maximum.
Smaller particles provide greater resistance to reconstruction, which is why P-6 sits near the top of the paper-security classification system.
How Secure Is P-6 Shredding?
P-6 represents a very high paper-destruction security level.
Its small maximum particle size makes reconstruction significantly more difficult than with lower P-levels.
However, particle size is only one part of secure information destruction.
Consider a box of highly confidential records waiting to be shredded.
Even if those documents will eventually be reduced to P-6 particles, the information may still be exposed if the records are:
- Left unattended
- Stored in an unlocked area
- Placed beside an ordinary recycling bin
- Transported without appropriate controls
- Accessible to unauthorized personnel
- Handled without clear accountability
A strong destruction program therefore considers both:
How securely the information is handled before destruction
and:
How thoroughly the material is destroyed at the end
P-4 vs. P-5 vs. P-6 vs. P-7 Shredding
P-4 through P-7 represent progressively higher paper-security classifications.
P-4 Shredding
P-4 permits a maximum particle area of 160 mm².
It is an established security level that may be appropriate for many types of confidential business information when consistent with the organization's applicable requirements and policies.
P-5 Shredding
P-5 reduces the maximum permitted particle area to 30 mm².
It provides greater resistance to reconstruction than P-4 and may be considered when an organization requires a higher destruction level.
P-6 Shredding
P-6 reduces the maximum particle area to 10 mm².
It may be considered for particularly sensitive records or situations where internal policy, contractual requirements, government requirements, risk assessment, or information sensitivity calls for very high-security destruction.
P-7 Shredding
P-7 permits a maximum particle area of 5 mm² and represents the highest paper-security level within the P classification.
It is associated with the most stringent paper-destruction requirements.
The important point is:
Higher security does not automatically mean the higher level is necessary for every document.
Organizations should select the destruction standard that matches the information and requirements involved.
Is P-6 More Secure Than P-5?
Yes.
P-6 provides a higher DIN paper-security classification because it requires smaller particles.
P-5 permits particles up to 30 mm².
P-6 reduces that maximum to 10 mm².
That makes the maximum permitted P-6 particle area approximately 67% smaller than the P-5 maximum.
But the useful question is not simply:
Which level is higher?
The better question is:
Which level does our information actually require?
P-5 may be completely appropriate when it satisfies the organization's requirements.
P-6 may be appropriate when the information, risk profile, contract, policy, or other applicable requirement calls for a substantially smaller particle size.
Is P-6 the Highest Shredding Security Level?
No.
P-7 is the highest paper-security level in the classification.
P-7 permits a maximum particle area of 5 mm², compared with 10 mm² for P-6.
That makes P-7 more stringent from a particle-size perspective.
Organizations should not automatically choose P-7 simply because it is the highest available number.
Extremely high-security destruction can require specialized equipment and processes. The selected level should match the organization's actual security requirements rather than becoming a race toward the smallest possible particle.
What Documents Might Be Appropriate for P-6 Shredding?
P-6 may be considered for information an organization determines requires very high protection against reconstruction.
Depending on the organization and applicable requirements, examples could include particularly sensitive:
- Research and development records
- Proprietary technical information
- Intellectual property
- Strategic plans
- Product designs
- Investigative materials
- Legal records
- Financial information
- Government-related information
- Confidential corporate information
- Documents subject to heightened contractual requirements
Document category alone does not determine the correct security level.
For example, not every legal document, financial record, or proprietary business record automatically requires P-6.
Organizations should evaluate the sensitivity of the specific information and the requirements that govern it.
Does HIPAA Require P-6 Shredding?
P-6 should not be presented as a universal HIPAA requirement.
Organizations subject to HIPAA have responsibilities related to protecting and appropriately disposing of protected health information.
But businesses should evaluate the safeguards and destruction methods appropriate to their circumstances rather than assuming every paper record containing health information automatically requires a particular DIN P-level.
The same principle applies to other regulated information.
Separate these two questions:
- What does the applicable law, regulation, contract, or policy require?
- What destruction method and security level will the organization use to satisfy those requirements?
That distinction helps prevent a shredding security classification from being presented as a legal requirement when the underlying rule may not specify one.
Does P-6 Mean a Shredding Provider Is NAID AAA Certified?
No.
P-6 and NAID AAA Certification describe different things.
P-6
P-6 describes the particle requirements associated with a particular paper destruction security classification.
NAID AAA Certification
NAID AAA Certification is an information-destruction industry certification administered by i-SIGMA that evaluates applicable operational and security requirements.
Certification considers broader aspects of secure destruction operations rather than functioning as another name for a particular DIN particle level.
A provider being NAID AAA Certified therefore should not be interpreted as meaning every paper destruction service automatically produces P-6 particles.
If your organization requires P-6 or another specific destruction standard, confirm that capability directly with the provider before service.
Why Particle Size Is Only One Part of Secure Destruction
A document is still confidential until destruction occurs.
That means organizations should evaluate what happens at every stage.
Secure Collection
Confidential records should remain appropriately protected while waiting for destruction.
Secure collection containers can help reduce the chance that documents enter ordinary waste or recycling.
Controlled Handling
Authorized employees and destruction personnel should follow established procedures for handling sensitive materials.
Chain of Custody
Organizations should understand who controls confidential records as they move toward destruction.
Transportation
For off-site destruction, intact documents remain sensitive while being transported.
Facility Security
If documents are destroyed at a separate facility, access and handling controls remain important until destruction is complete.
Appropriate Destruction
The selected destruction process should match the organization's information sensitivity and applicable requirements.
Documentation
A Certificate of Destruction or other applicable documentation can provide a record associated with completion of the destruction service.
Recycling
After confidential information has been securely destroyed, the resulting paper can move into appropriate downstream recycling channels.
A strong information-destruction program combines these stages rather than focusing on shred size alone.
Should Your Business Use P-6 Shredding?
Start with the information.
Ask:
How Sensitive Is the Information?
Consider the potential consequences if someone reconstructed or gained unauthorized access to the documents.
Does a Contract Specify a Destruction Standard?
Customer, vendor, government, or other agreements may establish particular information-security requirements.
Does Internal Policy Require a Specific Level?
Some organizations establish their own destruction standards based on risk assessments and information classifications.
Does a Government Program Specify Requirements?
Government or defense-related work may involve specific destruction requirements that should be evaluated directly.
Is P-6 Actually Necessary?
A higher security classification may provide greater resistance to reconstruction, but unnecessary over-specification can complicate operations without providing meaningful additional value for routine records.
Can Your Provider Support the Required Standard?
If a particular P-level is mandatory, verify the provider's destruction capabilities before materials enter the destruction process.
P-6 vs. Overall Information Risk
Organizations should avoid making security decisions using particle size alone.
Consider two hypothetical scenarios.
Scenario A
Documents are shredded to P-6, but before destruction they remain for several days in open boxes accessible to unauthorized personnel.
Scenario B
Documents are securely collected, access is controlled, chain of custody is maintained, and an appropriate destruction level is used based on the organization's actual requirements.
The second process may provide a much stronger overall information-security program even if the final particle level is not automatically the highest available classification.
That is why secure destruction should be evaluated from collection through final processing.
On-Site vs. Off-Site High-Security Shredding
Where destruction occurs is a separate question from the P-level achieved.
Mobile On-Site Shredding
Mobile on-site shredding allows documents to be destroyed at the customer's location.
Organizations may prefer on-site service when they:
- Want records destroyed before material leaves the property
- Prefer the ability to observe destruction
- Have internal policies favoring on-site service
- Are completing a large purge at one location
Secure Off-Site Shredding
Secure off-site shredding involves controlled collection and transportation to a secure destruction facility.
Organizations using off-site service should evaluate transportation, facility security, chain of custody, and destruction procedures.
Remember:
On-site vs. off-site tells you where destruction occurs.
P-6 tells you the paper destruction security classification.
They describe different aspects of the service.
Questions to Ask if Your Organization Requires P-6
If P-6 or another specific particle standard is important, do not assume.
Ask the provider:
- What paper security levels can you provide?
- Can you specifically support P-6 destruction?
- What particle specifications apply?
- Is the required level available for this service and location?
- How are documents collected before destruction?
- How is chain of custody maintained?
- Where does destruction occur?
- Who handles the material?
- What documentation is provided?
- What relevant certifications does the provider maintain?
A professional destruction company should be able to clearly explain both the destruction method and the broader security process.

Frequently Asked Questions About P-6 Shredding
What is P-6 shredding?
P-6 is a very high-security paper destruction classification under DIN 66399 / ISO/IEC 21964. It permits a maximum particle area of 10 mm², with a maximum strip width of 1 mm for regular particles.
What size is P-6 shredding?
P-6 permits a maximum paper particle area of 10 mm². Actual particle dimensions can vary provided the applicable P-6 requirements are met.
Is P-6 more secure than P-5?
Yes. P-6 permits a smaller maximum particle area than P-5 and therefore represents a higher paper-security classification.
Is P-6 the highest shredding level?
No. P-7 is the highest paper-security level within the P classification and permits particles up to 5 mm².
Does HIPAA require P-6 shredding?
P-6 should not be described as a universal HIPAA requirement. Organizations should evaluate the disposal safeguards and destruction methods appropriate to their circumstances and applicable requirements.
Does NAID AAA Certification mean documents are shredded to P-6?
No. NAID AAA Certification and DIN P-levels describe different aspects of secure information destruction. If a particular P-level is required, verify that capability directly with the provider.
What documents need P-6 shredding?
There is no universal document category that automatically requires P-6. It may be considered for particularly sensitive information or when contractual, governmental, internal, or other applicable requirements call for very high-security destruction.
Is P-7 better than P-6?
P-7 has a smaller maximum particle requirement and therefore provides a higher paper-security classification. Whether it is appropriate depends on the information and requirements involved.
Can businesses use P-6 for ordinary confidential records?
They can if the provider supports it, but organizations should determine whether that level is necessary based on information sensitivity, requirements, policies, and risk rather than automatically selecting the highest available level.
Is particle size the most important part of secure shredding?
Particle size matters, but it is only one element. Secure collection, chain of custody, personnel, transportation, facility controls, destruction procedures, and documentation can all contribute to a secure information-destruction process.
Choose the Security Level That Matches the Information
P-6 shredding is a very high-security paper destruction classification.
With a maximum particle area of 10 mm², it provides substantially greater resistance to reconstruction than lower P-levels such as P-4 and P-5.
But the smallest available particle is not automatically the correct solution for every organization.
The better approach is to evaluate:
- Information sensitivity
- Applicable requirements
- Contracts
- Internal policies
- Risk
- Chain of custody
- Destruction capabilities
- Documentation
Then choose a destruction process that matches those needs.
