Certification Introduction
The North American market is divided into two independent regulatory regions, the United States and Canada, with no unified regional mandatory certification system. For construction machinery to be launched on the market 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 condition for product market access, and non-compliant products cannot be cleared to enter the market.
Laws and Regulations
- United States: Emissions of non-road construction machinery engines are regulated under the Clean Air Act (CAA), supervised by the U.S. Environmental Protection Agency (EPA); occupational safety follows regulations of the Occupational Safety and Health Administration (OSHA); safety product certification complies with 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 compliant test results obtained in the United States are partially recognized.
Technical Requirements
- Emission requirements: The United States implements the EPA Tier 4 Final standard, with stricter limits under the 2026 new regulation: NOₓ≤0.05 g/kW·h, PM≤0.005 g/kW·h. Mandatory installation of DPF+SCR aftertreatment system, addition of a 150-hour durability test, sound power level limit ≤85 dB(A); Canada implements emission requirements equivalent to US Tier 4.
- Safety requirements: The United States follows ANSI series safety standards (e.g. ANSI B30.02 applies to cranes), requiring structural strength to meet safety factor standards, guardrail height to conform to 1070mm±50mm, and electrical systems to adapt to North American 480V/60Hz power supply standards; Canada follows corresponding CSA safety standards.
- Label and documentation requirements: Products must be marked with EPA factory registration number, official compliance number and safety warning information, and complete technical specifications in both Chinese and English must be provided.
Certification Process
Confirm product classification and applicable regulatory requirements for the target market (United States/Canada), send samples to a laboratory accredited by the regulatory authority to complete emission and safety tests, organize a full set of technical documents (including instruction manual, test report, nameplate design drawing, etc.), submit the certification application to the corresponding regulatory authority, wait for the authority to review materials and test results, obtain the certificate of compliance after passing the review, complete factory registration and submit annual compliance reports as required.
