Testing Lab of Power Supply/ IT / AV Products

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

Step 1: Identify Your Product Classification

Power supply and battery products fall into distinct regulatory categories, each with specific certification requirements. Accurate classification is the foundation of an efficient certification strategy:

• 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 Target Marketplace

• U.S. (Amazon.com) — 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 (Amazon.de, etc.) — CE LVD (EN 62368-1 safety) + CE EMC (EN 55032/55035) + ErP (EC 278/2009 for EPS) + RoHS + UN 38.3 + EN 62133 (battery safety)
• Japan (Amazon.co.jp) — PSE Category A (J 62368-1) + J 55032 (EMC) + PSC mark (battery safety per electrical appliances law) + UN 38.3

Step 3: Prepare Technical Documentation

Complete and accurate documentation is essential for a smooth certification process. The following items are typically required:

• Circuit schematic diagram and PCB layout files
• Bill of Materials (BOM) with component specifications and safety certifications
• Transformer specification sheet (for power supply products)
• Battery specification sheet including cell model, capacity, voltage, and chemistry
• Product label artwork (showing all required markings, ratings, and certifications)
• User manual in the language of the target market

Step 4: Submit Samples and Execute Testing

Provide production-level samples that are representative of the final product. Key guidelines:

• Submit at least 2 units (1 for testing + 1 backup) for power supply products
• For UN 38.3 battery testing, the required sample count depends on the test item (typically 10-20 cells and 4-8 batteries)
• 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: Obtain Reports and Upload to Amazon

Once all testing is complete, review the reports carefully before uploading to Amazon Seller Central. Ensure that:

• All model numbers and product identifiers in the reports match the Amazon listing exactly
• The testing laboratory is recognized by the relevant accreditation body (A2LA, NVLAP for FCC; ISO 17025 for CE)
• UN 38.3 reports cover all 8 test items (T.1 through T.8) with complete test data
• Battery safety reports are at the appropriate level (cell-level and/or pack-level as applicable)
