The fascial gun, as a popular category of fitness equipment, features a built-in lithium battery (mostly large-capacity cylindrical/supercapacitor models, suitable for high-frequency vibration scenarios, and some are detachable). The lithium battery is the core component. According to the requirements of the "Electrical and Household Appliance Safety Management Act" in South Korea, the battery of the fascial gun must obtain KC certification before it can legally enter the South Korean market for sales and be listed on local e-commerce platforms. Without certification, it will face customs clearance obstacles, fines, and product recalls.
I. Awareness and Popularization: What is KC Certification? Why is the battery of the fascial gun necessary to obtain?
(1) Core Definition and Standard Basis
KC certification is a mandatory product safety certification in South Korea, supervised by the Korea Institute of Standards (KATS). The core basis for KC certification of the fascial gun battery is the KC 62133-2:2020 standard (corresponding to IEC 62133-2:2017), and it must also comply with the EMC standards KN 32:2020, KN 35:2020 requirements, and the new regulations added in 2025: no spread of thermal runaway from a single cell to adjacent cells within 30 minutes after thermal runaway, and additional random vibration tests are required for high-frequency vibration scenarios, with the resistance of short-circuit tests tightened to ≤5mΩ. The certification needs to be reviewed by recognized institutions such as KTL and KTR in South Korea, and CB reports cannot be directly converted for certification.
(2) Scope of Application and Core Judgement Criteria
Applicable to all built-in or detachable lithium batteries of fascial guns (mostly 100-500Wh large-capacity models), covering various household and commercial fascial gun accessories. Core judgement: safety performance meets requirements (passing tests for overcharge, short circuit, compression, etc., without fire, explosion, or leakage risks); EMC electromagnetic compatibility meets the limit values; compatible with high-frequency vibration scenarios, vibration tests meet standards; meets the new heat diffusion blocking regulations; and is well adapted to the fascial gun as a whole, with the detachable battery requiring separate certification.
(3) Core Necessity of Obtaining KC Certification
1. Mandatory entry, without certification, it cannot pass the customs clearance in South Korea, and sales violations will face a maximum 10% sales fine and product recall; 2. Hard threshold for入駐 of South Korean e-commerce platforms (Coupang， Gmarket)， need to upload KC certificates and declaration of conformity confirmation； 3. Enhance trust between South Korean buyers and consumers， the KC logo is a locally recognized safety and compliance symbol； 4. Avoid supply chain risks， fascial gun manufacturers need to verify the validity of KC certification when purchasing batteries.
II. Practical Guidance： The Complete Process of KC Certification for Fascial Gun Batteries
(1) Required Application Materials
Need to provide the three-language versions (with official seal)： 1. 5 sets of finished batteries， 20 samples of uncharged cells (consistent with production， with complete nameplates)； 2. Business license， ISO 9001 system documents (if not from the own factory， attach authorization)； 3. Specification sheet， BMS function description， KC compliance proof of core components； 4. Application form， declaration of conformity， test commission agreement； 5. Product photos， Korean manual， pre-report of vibration compatibility test.
(2) Complete Processing Flow (5 steps for efficient certification)
1. Select a certified institution and laboratory recognized by KATS in South Korea； 2. Submit materials and samples， after review， start the case； 3. Complete all-item tests according to standards and new regulations， if不合格， issue rectification suggestions； 4. Review test reports and materials， without error， issue a 5-year certificate； 5. Standardly affix the KC logo， retain technical documents for 5 years for future reference.
(3) Key Precautions
1. Adapt to new regulations， complete heat diffusion blocking and high-frequency vibration tests； 2. Samples and production products parameters， components must be completely consistent， vibration compatibility design must meet standards； 3. Provide Korean versions of key documents (manual， warning labels)， no translation errors； 4. Annual inspection of the certificate is required， after obtaining the certificate， regular factory review is required； 5. Choose a recognized institution. Unrecognized reports cannot be used for market entry.
III. Service Transformation: Choose ZRLK. The KC certification of the fascial gun battery ensures efficient customs clearance and smooth market entry.
The KC certification of the fascial gun battery involves Korean language materials, local laboratory collaboration, and adaptation to new regulations, which is quite challenging. ZRLK collaborates with the Korean KATS recognized institution and laboratory to provide a full range of services: 1. Authoritative qualifications, certificates recognized across Korea, suitable for customs and e-commerce reviews; 2. Pre-inspection, identifying non-compliance items such as vibration compatibility and heat diffusion; 3. One-on-one guidance, assisting in preparing multilingual materials, sample testing, and labeling; 4. Support for expedited services, connecting with local laboratories to shorten the cycle; 5. Real-time synchronization of Korean regulatory dynamics, providing product optimization suggestions to ensure long-term compliance.
The KC certification of Korean fascial gun batteries is highly regulated, and the new regulations have further raised the compliance requirements. Certification is the core prerequisite for entering the Korean market.
