Certified. Compliant.
Production Ready.
HMW Services handles UL certification for both currently running machines and new equipment imports from China — ensuring your facility meets every US safety and compliance standard before production begins.
Why UL Certification Matters
In the United States, operating non-certified industrial equipment exposes your business to serious liability — insurance claims, OSHA violations, production shutdowns, and facility-wide safety risks. UL certification is not optional; it's the baseline for legal, insurable operation.
For companies importing equipment from China, the challenge is compounded. Chinese-manufactured machines are built to different standards and rarely arrive UL-listed. Without proper certification, that equipment cannot legally operate in a US facility.
HMW Services bridges this gap. Our team has deep expertise in both Chinese manufacturing standards and US compliance requirements — we know exactly what needs to change, what documentation is required, and how to get your equipment certified efficiently.
Risks of Non-Certified Equipment
- Insurance claim denials after incidents
- OSHA citations and facility shutdowns
- Personal liability for injuries
- Production downtime and lost revenue
- Inability to pass facility safety audits
Two Certification Paths
Whether you have equipment already running or new machines arriving from China, we have a proven process for each scenario.
Currently Running Machines
Equipment already in operation that was never properly certified, or machines that have been modified since original certification. We assess current state, identify gaps, and bring the equipment into full compliance.
Process Steps
- 1
Equipment Assessment
Full inspection of electrical systems, controls, safety devices, and mechanical components
- 2
Gap Analysis
Identify all deviations from NEC, NFPA 79, and applicable UL standards
- 3
Remediation
Modify wiring, replace non-compliant components, install required safety devices
- 4
Documentation
Prepare complete technical file: schematics, BOM, safety analysis
- 5
Certification
Submit for UL field evaluation or third-party NRTL certification
New Imports from China
Equipment purchased from Chinese manufacturers and being imported to the US for the first time. We manage the entire compliance process from pre-shipment review through final certification.
Process Steps
- 1
Pre-Shipment Review
Review factory documentation, schematics, and component specs before equipment ships
- 2
Customs & Delivery
Coordinate import documentation and on-site delivery
- 3
Incoming Inspection
Verify equipment matches specifications and identify compliance gaps
- 4
Compliance Modifications
Upgrade electrical systems, controls, and safety devices to US standards
- 5
Certification & Commissioning
Obtain UL certification and commission equipment for production
Code Expertise
Electrical Standard for Industrial Machinery
The primary US standard governing electrical equipment on industrial machines. We ensure full compliance with wiring methods, overcurrent protection, control circuits, and safety functions.
National Electrical Code (NFPA 70)
Governs electrical installations in facilities. Our installations meet all NEC requirements for industrial occupancies, including panel installations and field wiring.
Industrial Control Panels
The UL standard for industrial control panel construction. We design and build panels to UL 508A requirements, enabling listing by a recognized NRTL.
Occupational Safety Standards
All certified equipment meets applicable OSHA machine guarding, lockout/tagout, and electrical safety requirements.
Safety of Machinery — Electrical Equipment
For equipment with international origins, we reconcile IEC 60204 designs with US NFPA 79 requirements.
Industrial Control Panels for Hazardous Locations
For facilities with classified hazardous areas, we provide compliant panel design and certification.
What's Included
Electrical Panel Certification
Design, build, or modify control panels to UL 508A standards with full documentation.
