- 具体要求What the rule requires
- CARB 将 TRU 描述为用柴油内燃机驱动、在易腐产品运输中提供制冷或加热的系统。检查冷藏运输环保状态时，应查明所用机组和设备类型；牵引车检测合格，不能证明冷机也合格。CARB describes TRUs as diesel-internal-combustion-engine systems that refrigerate or heat perishable products in transport. Identify the unit and equipment type separately when checking emissions status; a tractor’s passing test does not establish the refrigeration unit’s compliance.
Transport Refrigeration Units (TRU) are refrigeration systems powered by diesel internal combustion engines designed to refrigerate or heat perishable products that are transported in various containers, including truck vans, semi-truck trailers, shipping containers, and railcars.

- 具体要求What the rule requires
- CARB 项目页载明，2022 年修订于 2022 年 10 月 1 日生效，涉及 TRU 运营费和适用设施登记费；2025 年 SB 153 授予相关收费权限。缴费对象、期限和设备达标情况，应通过项目页链接的现行指引、登记和合规查询确认。本页不提供适用于所有设备的统一收费金额或淘汰日期。CARB states that the 2022 amendments took effect October 1, 2022 and address TRU operating fees and applicable facility-registration fees; SB 153 in 2025 authorized related fee collection. Use the linked current guidance, registration and compliance tools to establish who owes what, when, and whether a unit complies. This page does not invent a universal fee or retirement date for every unit.
On February 24, 2022, CARB approved amendments (2022 Amendments) to the Transport Refrigeration Unit Air Toxic Control Measure (TRU ATCM) for In-Use Diesel-Fueled TRUs (Title 13 CCR §§ 2477–2477.24), effective October 1, 2022. The 2022 Amendments require TRU and facility owners or owner/operators to pay operating and registration fees, respectively. On September 17, 2025 Governor Newsom signed Senate Bill (SB) 153 granting CARB authority to impose fees on entities regulated under the 2022 Amendments to the TRU ATCM.
Guidance documents and answers to frequently asked questions are now available to assist stakeholders with TRU operating and applicable facility registration fee requirements.
