Starting July 1, 2026, China's mandatory new national standard for new energy vehicles takes effect. The standard covers three core dimensions: battery safety, electromagnetic compatibility, and functional safety. It imposes stricter requirements on battery thermal runaway, vehicle EMC, and intelligent driving functional safety. This standard directly elevates the safety baseline for Chinese export NEVs—providing quality assurance for overseas buyers while potentially changing market access thresholds.

Core Changes: From "Recommended" to "Mandatory"

Previously, Chinese NEV safety standards were largely recommendations with inconsistent implementation. The new mandatory standard means non-compliant products cannot obtain market approval.

Three core dimensions:

Battery Safety

• Thermal runaway warning: Battery packs must warn occupants at least 5 minutes before thermal runaway occurs.
• Thermal propagation suppression: A single cell thermal runaway must not propagate to adjacent cells (or be delayed sufficiently for escape).
• Crash safety: Added side pole impact and bottom ball strike scenarios.

Electromagnetic Compatibility (EMC)

• Tighter vehicle electromagnetic radiation emission limits.
• Enhanced anti-interference capability for stable electronic system operation in complex electromagnetic environments.
• Specialized requirements for wireless communication modules in intelligent connected vehicles.

Functional Safety (FuSa)

• ADAS systems must meet ASIL level requirements.
• Key sensors (radar, camera, LiDAR) require redundancy and fault detection.
• SOTIF (Safety of the Intended Functionality) included to prevent unexpected behavior in non-fault scenarios.

Immediate Industry Impact

Higher Technical Barriers

Some smaller manufacturers with insufficient technical reserves face product rectification pressures. The new standard is expected to temporarily suspend sales or require technical upgrades for some models.

Cost Pass-Through

Battery safety upgrades (thermal insulation, pressure relief valves, BMS upgrades) increase per-vehicle costs. Industry estimates suggest 2,000-5,000 yuan per vehicle. For price-sensitive markets, this may affect terminal competitiveness.

"Safety Premium" for Export Products

The new standard's safety requirements approach or meet EU, Australian, and other mainstream market access requirements. Export models meeting the new standard will gain "safety compliance" competitive advantages overseas, reducing duplicate certification costs.

Opportunities and Cautions for Overseas Buyers

Opportunity: Elevated Export Safety Baseline

All Chinese export NEVs must meet this elevated safety baseline after July 1. Overseas buyers can procure Chinese products with greater confidence, as safety standards have been uniformly raised.

Caution: Transition Period Products

Vehicles produced before July 1 but not yet exported may have been built to the old standard. Buyers should specify production dates and compliance standard versions in procurement contracts, prioritizing post-July 1 new-standard models.

Caution: Certification Differences Across Markets

While the new standard approaches international standards, individual countries still have differences. For example, EU R100 (battery safety) and R79 (steering functional safety) have additional requirements. Buyers in export markets should still require suppliers to provide complete certification documentation for target markets.

Industry Outlook

The new standard's implementation marks China's shift from "scale expansion" to "quality improvement" in NEVs. Over the next 2-3 years, more sub-domain standards are expected (solid-state battery safety, V2G functional safety, autonomous driving system safety, etc.).

For overseas buyers, China's new national standard should serve as a reference for evaluating supplier technical capabilities. Companies that proactively adapt and exceed new standard requirements typically demonstrate stronger technical strength and more robust quality systems.
