For B2B suppliers looking to sell on Alibaba.com with industrial face shields, understanding international safety certifications is non-negotiable. Buyers from North America, Europe, and Southeast Asia have distinct certification requirements that directly impact purchasing decisions. This section breaks down the two dominant standards governing face shield manufacturing and what they mean for your product positioning.
ANSI/ISEA Z87.1-2025: The US Standard
The American National Standards Institute (ANSI) and International Safety Equipment Association (ISEA) jointly publish the Z87.1 standard, which serves as the foundation for eye and face protection in the United States. The latest revision, ANSI/ISEA Z87.1-2025, was published in January 2026 and represents a significant update to testing protocols and marking requirements.
Key marking requirements under Z87.1-2025 include:
- Z87: Basic marking indicating compliance with the standard
- Z87+: High impact protection rating
- D3: Protection against liquid droplets and splashes
- D4: Protection against dust particles
- D5: Protection against fine dust particles
- X: Anti-fog coating (optional marking)
- S: Special tint or lens treatment
These markings must be permanently affixed to both the lens and the headgear, ensuring traceability and compliance verification throughout the product lifecycle.
The 2025 revision introduces more harmonized testing methods and clearer performance-based language. Manufacturers must now provide detailed documentation of testing procedures and results for each product variant.
EN 166 and the Transition to EN ISO 16321: The European Standard
For suppliers targeting European buyers on Alibaba.com, EN 166 has been the governing standard for personal eye protection. However, a major regulatory shift is underway: EN ISO 16321-1 will replace EN 166:2001 starting November 11, 2025 for all new certifications in the UK and EU.
EN 166 certification includes several classification codes that buyers commonly reference:
- Optical Class: Class 1 (highest optical quality), Class 2, Class 3
- Mechanical Strength: S (increased robustness), F (low energy impact), B (medium energy impact), A (high energy impact)
- Optional Risk Protection: 3 (liquid droplets), 4 (large dust particles), 5 (fine dust), 8 (electrical arc), 9 (thermal hazards)
- Surface Treatment: K (anti-scratch), N (anti-fog)
Suppliers must ensure their face shields carry the appropriate CE marking and declaration of conformity for EU market access.
OSHA Compliance Requirements
The US Occupational Safety and Health Administration (OSHA) mandates under regulation 1926.102 that employers shall ensure employees use appropriate eye and face protection when exposed to hazards. Equipment must comply with ANSI Z87.1-2010, 2003, or 1989 versions, with side protection required where hazards exist from that direction.
Safety Standard Comparison: ANSI Z87.1 vs EN 166 vs EN ISO 16321
| Feature | ANSI Z87.1-2025 (US) | EN 166 (EU, until Nov 2025) | EN ISO 16321-1 (EU, from Nov 2025) |
|---|---|---|---|
| Impact Testing | High impact (+) and basic impact | Mechanical strength S/F/B/A | Updated impact performance criteria |
| Marking Requirements | Z87 or Z87+ on lens and headgear | CE mark plus optical and mechanical codes | CE mark plus updated classification |
| Anti-Fog and Anti-Scratch | Optional X marking | K (anti-scratch), N (anti-fog) | Retained with updated testing |
| Dust and Splash Protection | D3/D4/D5 codes | 3/4/5 codes | Harmonized with ISO standards |
| Certification Validity | Current standard | Valid for existing products until Nov 2025 | Required for new certifications from Nov 2025 |
