Simply put: In Taiwan, the only official proof of compliance for explosion-proof equipment in industrial air treatment is the TS Safety Mark. Under Occupational Safety and Health Administration (OSHA) regulations from the Ministry of Labor, electrical equipment used in combustible dust environments must pass formal type inspection and display the TS Mark to be legally compliant. Incorporating certified industrial air treatment solutions is vital for maintaining legal operations.
Many clients ask: “My equipment is already CE or ATEX certified—isn’t that enough?” The short answer is no. Much like driving with a foreign license, international credentials must be formally validated for local use. For effective and compliant industrial air treatment, here is a detailed look at Taiwan’s explosion-proof regulations and certification requirements.
1. Legal Framework for Explosion-Proof Equipment in Taiwan
- Occupational Safety and Health Facilities Rules (Article 177-1): Employers operating in areas with combustible dust hazards must use electrical machinery, tools, and equipment engineered with explosion-proof structures tailored to the specific hazard zone.
- Occupational Safety and Health Act (Article 6): Employers are strictly prohibited from providing machinery or tools for worker use that fail to meet central authority protective standards.
- Regulations Governing Information Reporting and Registration of Mechanical Equipment (Article 4): Explosion-proof electrical equipment must pass type inspection by accredited testing institutions, complete official registration, and display the TS Mark.
- Bottom Line: The law clearly mandates that any facility with dust explosion risks must use legally certified explosion-proof equipment.
2. What Is the TS Mark and How Is It Obtained?
- TS Mark Definition: Standing for “Taiwan Safety,” this mark is certified by the Ministry of Labor’s OSHA to prove a product has passed official type inspection.
- Governing Body: Occupational Safety and Health Administration, Ministry of Labor.
- Accredited Testing Bodies: Authorized institutions (such as the Industrial Safety Technology Center) conduct official type evaluations.
5-Step Acquisition Process:
- Submit application for type inspection to an accredited body.
- Pass evaluation and secure certification.
- Register on the official Mechanical Equipment Registration Platform.
- Obtain the official registration certificate.
- Affix the TS Safety Mark onto the product.
- Customs Clearance: Equipment imported from abroad must complete this registration process before customs will release the shipment.
3. Can International Certifications (ATEX/IECEx) Be Used in Taiwan?
- ATEX Certification (EU): Cannot be used directly. ATEX is an EU directive with fundamental structural differences from Taiwan’s certification system. It cannot be converted directly into a domestic permit.
- IECEx Certification (International): Partially applicable. If a product holds valid IECEx documentation aligned with Taiwan’s standard baselines, those papers serve as accepted supporting evidence. However, it must still undergo formal type inspection through accredited Taiwanese testing bodies to earn the TS Mark.
- Bottom Line: Only the TS Mark provides legal compliance under Taiwanese law. However, having ATEX or IECEx papers significantly speeds up TS Mark testing because the core technical standards closely overlap.
4. National Standard Cross-Reference (CNS vs. IEC)
- General Requirements: CNS 3376-0 correlates directly to IEC 60079-0.
- Flameproof Enclosure “d”: CNS 3376-1 correlates directly to IEC 60079-1.
- Pressurized Enclosure “p”: CNS 3376-2 correlates directly to IEC 60079-2.
- Intrinsic Safety “i”: CNS 3376-11 correlates directly to IEC 60079-11.
- Encapsulation “m”: CNS 3376-18 correlates directly to IEC 60079-18.
5. Risks of Using Uncertified Explosion-Proof Equipment
- Labor Inspection Penalties: OSHA audits will issue immediate citations and fines under the Occupational Safety and Health Act if non-TS marked equipment is found.
- Insurance Claim Denials: Insurers can refuse coverage payouts following an explosion incident on the grounds of “unlawful equipment use.”
- Criminal Liability: In the event of worker injuries or fatalities, facility management faces potential criminal charges for professional negligence.
- Customs Hold-ups: Imports lacking proper TS Mark registration risk being impounded at customs.

Appendix: Explosion-Proof Equipment Self-Assessment Checklist
- Is your dust classified as combustible/explosive? (Yes: Requires explosion-proof equipment)
- Does your current dust collector have explosion protection? (No: High Risk)
- Is a TS Safety Mark affixed to the equipment for industrial air treatment? (No: Regulatory Risk)
- Do you hold ATEX or IECEx international certifications? (Yes: Can accelerate TS application)
- Have you been subjected to labor inspections? (No: Risk of unannounced audits)
If your facility handles combustible dust, using legally certified explosion-proof equipment is non-negotiable. If you have questions about your setup, reach out to USONIC for expert guidance.
