The Environmental Protection Department today announced updated qualifying standards (QS) for the First Registration Tax concessions for environment-friendly commercial vehicles (EFCVs). The new standards will be in effect from April 1, 2026, to March 31, 2027.

For heavy-duty commercial vehicles exceeding 3.5 tonnes, the QS will be revised to include national requirements. To qualify, vehicles must emit at least 30% less nitrogen oxides (NOx) than the China VI-b or Euro VI emission limits.

As the NOx emission limits for both standards are identical, the existing QS emission limit will remain unchanged.

For light-duty commercial vehicles not exceeding 3.5 tonnes (excluding taxis), the standard will be tightened to require emissions not exceeding the China 6b limit. This is approximately 40% to 60% of the Euro 6 standard.

The QS for taxis will remain unchanged, requiring NOx emissions to be at least 80% lower than the Euro 6 limit.

The First Registration Tax concession rates and caps for all EFCVs will remain the same.
