Shanghai, China – December 11, 2025
Shanghai Qianjing Ducting Co., Ltd., a subsidiary of Shanghai Xuanyuan, has officially obtained the UL 181 certification issued by UL Solutions. The certification confirms that Qianjing’s HVAC duct systems meet the strict safety, fire resistance performance and operation standards in the United States and internationally.
Certification at a Glance
UL 181 Certified
UL 181 certification issued by UL Solutions for factory-made air ducts, connectors and related components.
HVAC Air Duct Systems
Qianjing’s HVAC duct systems are covered by the UL 181 certification.
Fire & Safety Performance
Certification demonstrates compliance with U.S. safety and fire performance requirements.
International Applications
Reliable performance in commercial, industrial and residential HVAC applications, with compatibility with global building codes.
What UL 181 Means for HVAC Ducting
The UL 181 standard applies to factory-made air ducts, connectors and related components used in HVAC systems. Certification under UL 181 demonstrates:
- Compliance with U.S. safety and fire performance requirements
- Proven structural integrity and airtightness
- Reliable performance in commercial, industrial and residential HVAC applications
For customers, specifying UL 181 certified ducting reduces compliance risk, shortens project approval cycles, and ensures compatibility with global building codes.
A Milestone for Product Safety and Quality
The certificate presentation ceremony was held at the company’s Shanghai headquarters, with UL Solutions representatives formally presenting the UL 181 certificate to Qianjing’s management team. The golden certificate, symbolizing global trust, marks the company’s transition from domestic manufacturing excellence to certified international supply capability.
From R&D to Quality Control
Achieving UL 181 certification required end-to-end alignment across:
- Product design and R&D for optimized airflow and durability
- Material selection meeting flame spread and smoke development limits
- In-house testing aligned with UL’s technical protocols
- ISO-based quality management systems ensuring batch-to-batch consistency
This certification is both an endorsement of Qianjing’s technical capability and a fulfillment of its long-standing commitment to deliver safe, high-quality, code-compliant ducting solutions.
A New Starting Point for Global Expansion
“UL 181 certification is not an endpoint, but a higher starting point,” said a company spokesperson. “Guided by our philosophy—‘Humility Casts Crystal, Pipes Connect the Future’—we will continue to innovate, strengthen quality control, and bring the credibility of Made in China ducting to global markets.”
