Testing Lab of Power Supply/ IT / AV Products

What certifications are required for power supply and battery products to be listed on TEMU? The compliance framework spans safety, EMC, energy efficiency, and battery safety across multiple testing standards and marketplaces. This step-by-step guide walks sellers through the complete certification process for power supply and battery products targeting TEMU's major marketplaces.

Step 1: Classify Your Product

Power supply and battery products fall into distinct regulatory categories, each with specific certification requirements:

• External Power Supply (EPS) — AC adapters, wall chargers, USB chargers: requires EMC + safety + energy efficiency (DOE/ErP)
• Power bank / Portable charger — requires EMC + safety + battery safety (UL 2054/UL 62133 + UN 38.3)
• Internal battery-powered device — laptops, tablets, wireless speakers: requires EMC + safety + battery safety
• Standalone lithium battery — replacement batteries, battery packs: requires UN 38.3 + battery safety standard

Step 2: Determine the Certification Package by Marketplace

• U.S. TEMU marketplace — FCC Part 15B (EMC) + UL 62368-1 (safety) + DOE Level VI (energy efficiency for EPS) + UN 38.3 (battery transport) + UL 2054/UL 62133 (battery safety)
• EU TEMU marketplace — CE LVD (EN 62368-1) + CE EMC (EN 55032/55035) + ErP (EC 278/2009) + RoHS + UN 38.3 + EN 62133 (battery safety)
• Japan TEMU marketplace — PSE Category A (J 62368-1) + J 55032 (EMC) + UN 38.3 + battery safety per applicable standard

Step 3: Prepare Technical Documentation

• Circuit schematic and PCB layout files
• Bill of Materials (BOM) with component safety certifications
• Transformer specification sheet (for power supply products)
• Battery specification sheet (cell model, capacity, voltage, chemistry)
• Product label artwork and user manual

Step 4: Submit Samples and Execute Testing

• Submit at least 2 production-level units for power supply products
• For UN 38.3 testing, provide 10-20 cells and 4-8 battery packs as required
• Multi-port chargers must be tested under each individual and combined output configuration
• Samples must match the production version in firmware, hardware, and labeling

Step 5: Upload to TEMU and Await Review

Once certification documents are obtained, upload them to TEMU Seller Center. The platform typically completes its review within 3 to 7 business days. Ensure that model numbers, product identifiers, and laboratory accreditations in the reports match TEMU's listing requirements exactly. Anchi Testing provides end-to-end certification services for power supply and battery products, ensuring every compliance dimension is covered for seamless TEMU listing.
