    Want to make the battery of your Bluetooth speaker compliant? Here are the key points to know for UN38.3 certification

    Author:中認聯科 time:2025-11-10 Ctr:792

    Portable Bluetooth speakers have long been the "atmosphere wonder" for outdoor camping and home leisure. As the core power supply component, the battery of the Bluetooth speaker, with its high capacity and lightweight features, directly determines the device's battery life and user experience. However, to ensure the safe transportation and smooth market entry of such batteries, UN38.3 certification is an indispensable key step

    I. Product Introduction

    The batteries of Bluetooth speakers are mostly lithium-ion or lithium metal batteries, which are compatible with various portable Bluetooth speakers. They feature a compact size and stable discharge performance, meeting the needs of diverse scenarios such as long-term outdoor playback and daily home use. They are the core components for ensuring the mobile use of Bluetooth speakers, and their safety performance is directly related to the overall safety of product use.

    Ii. Why Apply for UN38.3 Certification?

    1. Mandatory transportation safety requirements: UN38.3 is an international universal standard formulated by the United Nations for the transportation safety of lithium batteries, covering all transportation scenarios including air, sea and land transportation. Bluetooth audio batteries that have not passed the certification cannot be transported in compliance with regulations and may even be detained due to safety hazards.

    2. Essential conditions for market access: When domestic and foreign e-commerce platforms and offline dealers list Bluetooth audio products, they will clearly require the battery UN38.3 certification certificate. Without the certification, they cannot enter mainstream sales channels.

    3. Consumer trust foundation: Batteries that have passed authoritative certifications mean they have undergone multiple safety tests such as high and low temperatures, short circuits, and vibrations, which can effectively enhance consumers' trust in product safety.

    Iii. Materials Required for Certification Application

    Product specification sheet (including key parameters such as battery capacity, voltage, nominal energy, and size);

    2. Product structure diagram and circuit diagram (clearly marked with the internal structure of the battery);

    3. Test samples (Provide 3-5 sets of qualified samples as required by the laboratory);

    4. Business license of the manufacturer and trademark registration certificate (if any);

    A fully completed UN38.3 certification application form.

    Iv. Certification Application Process

    1. Consultation and communication: Customers contact ZRLK, explain the specifications and requirements of the Bluetooth speaker battery, and a professional team will provide a customized certification solution.

    2. Document Review: The client submits the above-mentioned materials. Once the review is passed, the next stage will be carried out.

    3. Sample testing: The laboratory conducts full-item testing in accordance with the UN38.3 standard, and provides real-time feedback on the progress throughout the process.

    4. Certificate Issuance: After passing the inspection, an authoritative inspection report and certification certificate will be issued to facilitate the rapid compliance of products.

    The UN38.3 certification for Bluetooth speaker batteries is a core guarantee for safe transportation and market access, and it is also an important manifestation of product compliance. With professional testing qualifications and efficient service processes, ZRLK provides one-on-one assistance to customers throughout the certification process, enabling products to smoothly enter domestic and international markets.
