Japan's PSE+JIS S 2021 Dual Certification for Smart Baby Strollers & Rockers from 2026

Introduction

Starting April 1, 2026, Japan will enforce a dual certification requirement (PSE diamond mark + JIS S 2021:2025) for smart baby strollers and electric rockers with USB charging, Bluetooth control, or motorized functions. This regulatory update by METI mandates grid failure simulation testing by designated agencies, directly impacting OEM manufacturers, particularly in China's Guangdong-Guangxi production cluster where lead times have extended to 8–10 weeks. The move signals Japan's tightening integration of electrical safety and child product structural standards for connected nursery goods.

Event Overview

On March 27, Japan's Ministry of Economy, Trade and Industry (METI) revised its Technical Guidelines for Imported Children's Products, specifying that:

• Effective date: April 1, 2026
• Scope: Smart baby strollers and electric rockers with USB/Bluetooth/motor functions
• Requirements: Concurrent PSE diamond certification (electrical safety) and JIS S 2021:2025 compliance (structural safety)
• Testing: Mandatory grid anomaly simulation by METI-approved labs

Impact on Sub-Sectors

1. OEM Manufacturers

Southern China's production hubs (Guangdong/Guangxi) report 8–10 week certification delays due to:

• Redesigned circuit protection for grid failure tests
• Dual documentation for PSE and JIS audits

2. Component Suppliers

Battery/power management system providers must:

• Verify components meet METI's voltage fluctuation thresholds
• Update technical files for dual-certification traceability

3. Export Logistics

Forwarders note increased pre-shipment inspections for:

• Physical JIS structural tags alongside PSE labels
• Revised HS code declarations for smart-enabled units

Key Action Points

1. Certification Timeline Planning

Factor in 12–14 weeks for:

• Grid test scheduling at METI-approved labs (currently 6 agencies)
• JIS documentation review cycles (avg. 20 working days)

2. BOM Cost Adjustments

Anticipate 3–5% cost increases from:

• Redundant safety components for grid failures
• Dual compliance labeling requirements

3. Market Prioritization

Consider tiered rollout strategies:

• Prioritize Japan-bound shipments with simpler mechanical models
• Delay smart feature launches until Q3 2025 certification completions

Industry Perspective

Analysis suggests this reflects Japan's broader trend of:

• Converging IoT safety standards across childcare categories
• Shifting liability to manufacturers through designated testing

Current data indicates 23% of China-made smart strollers exported to Japan may require redesigns for JIS S 2021 structural tests.

Conclusion

This regulatory change represents a strategic alignment of Japan's electrical and childcare safety frameworks, with immediate supply chain repercussions. Manufacturers should treat this as a compliance inflection point rather than incremental update, given the integrated testing requirements. Proactive engagement with METI-recognized labs before Q4 2025 is advised to mitigate shipment bottlenecks.
