New Regulations for Flatbed Semi-Trailers in 2026: Three Things You Need to Know
2026 is already halfway over, and several new regulations for flatbed semi-trailers are either about to be implemented or still under consultation.
I’ll get straight to the point.
First, two things to do before July:
First, trailers transporting hazardous materials need to pay attention.
The “Safety Technical Conditions for Vehicles Transporting Dangerous Goods” (GB 21668-2025) will officially take effect on July 1st. New models have been following the new standard since April this year, and older models must be upgraded by the end of the year at the latest. If you still have hazardous goods trailers that haven’t been upgraded, you need to do it now, don’t wait until the inspection deadline.
Second, trailer testing methods will be updated on August 1st.
The “Test Methods for Freight Trailers” (GB/T 13873-2026) will be implemented on August 1st, and testing institutions and manufacturers must submit announcements and declarations according to the new methods. Ordinary vehicle owners don’t need to worry about this, but if you’re involved in trailer manufacturing, remember to remind your technical department to familiarize themselves with it beforehand.
Two more things that are easily misunderstood: Increased safety features (ESC, AEBS, EBS, etc.) only apply to newly manufactured commercial trucks; existing vehicles do not need them. Some online claims are alarmist; don’t believe them.
GB 1589 (size and axle load standard) has not been implemented. The draft for comments did raise the single-sided single-tire axle load from 7 tons to 8 tons, but it’s still in the approval process. Don’t take this as a reason to overload.
One last piece of truth:
Don’t use low-bed semi-trailers to haul general cargo. According to current standards, they can only haul non-detachable large items, and traffic police are constantly checking them.
Electric trailers have a chance—the revised draft of GB 7258 has changed the definition of a trailer. Trailers with batteries and electric drive axles may be legal on the road in the future, but don’t rush, the official standard hasn’t been released yet.
In summary:
hazardous goods trailers should complete compliance by July; manufacturers should prepare for the new access review by January next year (Announcement No. 1 of 2026 issued by the Ministry of Industry and Information Technology, effective January 1, 2027); pay attention to other standards first, don’t be anxious.
