Construction Machinery — North America

The North American market consists of two independent regulatory jurisdictions, the United States and Canada, with no unified regional mandatory certification system. For construction machinery to be launched or cleared through customs in North America, it must meet the emission control and safety compliance requirements of the corresponding country. Relevant certification is a necessary prerequisite for product market access, and non-compliant products cannot be cleared for entry into the market.

United States: Emissions from non-road construction machinery engines are regulated under the Clean Air Act (CAA), overseen by the U.S. Environmental Protection Agency (EPA); occupational safety adheres to regulations of the Occupational Safety and Health Administration (OSHA); safety product certification complies with the requirements of the Nationally Recognized Testing Laboratory (NRTL) system. Canada: Emissions are regulated by Environment and Climate Change Canada, safety certification follows the framework of the Canadian Standards Association (CSA), and compliance test results already obtained in the United States are partially recognized.

Emission Requirements: The United States implements the EPA Tier 4 Final standard, and the 2026 new regulation tightens the emission limits: NOₓ≤0.05 g/kW·h, PM≤0.005 g/kW·h, with mandatory installation of DPF+SCR after-treatment systems, a newly added 150-hour durability test, and a sound power level limit of ≤85 dB(A); Canada implements emission requirements equivalent to U.S. Tier 4. Safety Requirements: The United States follows ANSI series safety standards (e.g., ANSI B30.2 applies to cranes), requiring structural strength to meet safety factor requirements, guardrail height to conform to 1070mm±50mm, and electrical systems to adapt to the North American 480V/60Hz power supply standard; Canada follows the corresponding CSA safety standards. Labeling and Documentation Requirements: Products must be marked with the EPA factory registration number, official compliance number and safety warning information, and complete Chinese-English technical specifications must be provided.
