The DIN 66399 Levels at a Glance
| DIN Level | Cut Type | Max Particle Size | Typical Use |
| P-1 / P-2 | Strip-cut | Wide strips | Non-confidential internal paper |
| P-3 | Cross-cut | <= 320 mm² | General business documents |
| P-4 | Cross-cut | <= 160 mm² | Confidential business - invoices, letters, HR memos |
| P-5 | Micro-cut | <= 30 mm² | Highly confidential - HR files, legal docs, personal data |
| P-6 | Micro-cut | <= 10 mm² | Highly confidential/secret - financial, classified records |
| P-7 | Micro-cut | < 5 mm² | Top secret / government |
Why P-4 Is the UAE Office Baseline
The UAE Personal Data Protection Law (Federal Decree-Law No. 45 of 2021) requires organisations to securely dispose of personal data held in physical form. Administrative fines are reported to range from AED 50,000 to AED 5 million depending on severity, though the law's executive regulations had still not been published as a discrete instrument as of mid-2026, so enforcement detail remains pending - take legal advice on your own position. DIN P-4 cross-cut is widely accepted as the practical minimum across general business documents: unlike strip-cut, it is not reversible by basic reassembly.
When to Step Up to P-5 or Higher
HR departments handling Emirates ID copies, salary details, and employment contracts
Law firms and legal departments shredding client-privileged material
Finance and accounting teams destroying bank statements, payroll records, or audit files
Healthcare providers disposing of patient records under both PDPL and sector-specific confidentiality rules
For multi-national organizations that also need to satisfy GDPR for EU-linked data subjects, DIN P-4 cross-cut generally covers routine business documents, with P-5 recommended for anything containing full personal identifiers.
Cross-Cut vs Micro-Cut - Practical Differences
| Factor | Cross-Cut (P-4) | Micro-Cut (P-5+) |
| Reassembly risk | Very low | Effectively none |
| Shred speed | Faster | Slightly slower |
| Bin fill rate | Slower (larger particles) | Faster (finer particles) |
| Typical cost | Lower | Higher |
FAQ
Q: Is DIN P-4 enough for UAE PDPL compliance? A: For most general office documents, yes. Documents with especially sensitive personal data warrant P-5 or higher - when in doubt, shred to the higher standard.
Q: Can one shredder handle both P-4 and P-5 needs? A: No - the cut level is a fixed hardware property of the machine. Offices with mixed sensitivity often keep a P-4 machine for daily use and route the most sensitive material through document destruction services rated P-5+.
Q: Does Sahara supply P-5 and higher shredders in the UAE? A: Sahara's standard rental and sale range is Fellowes Powershred DIN P-4 cross-cut; micro-cut and higher-security models are available on request - contact us with your requirement.
