What Hct Co.,ltd. does

HCT Co., Ltd. (주식회사 에이치시티) is a KOSDAQ-listed (ticker 005870) Korean Testing, Inspection, and Certification (TIC) company headquartered in Icheon-si, Gyeonggi-do, South Korea, founded in May 2000 as the Hyundai Calibration Certification Technology Institute and rebranded in 2007. The company operates across two core service lines: HCT Testing & Certification, spanning RF, EMC, SAR, OTA, electrical safety, medical devices, batteries, environmental reliability, software, nuclear, automotive, and defense testing under 14 specialized areas; and HCT Calibration Services, accredited under ISO/IEC 17025 via KOLAS (since 2003) and A2LA (since 2016) across length, mass, time/frequency, electricity, temperature/humidity, acoustics/vibration, light, ionizing radiation, and amount of substance. Supporting capabilities include cleanroom performance evaluation under ISO 14644, a Facility Monitoring System built on Testo Saveris hardware, defense precision measurement solutions, ISO 17034 certified reference materials (Korea's only particle counter standard calibration laboratory, traceable to the Swiss National Measurement Institute), an RF switch matrix automation system, oxygen pressure gauge cleaning under ASTM G93, and an official domestic sales agency for TESTO, KANOMAX, and Westenberg Wind Tunnels.

The business generates revenue through professional-service fees for testing and certification projects, calibration fees published per measurement field (most recently revised July 2025), managed services for facility monitoring, and hardware sales of measurement equipment plus aftermarket calibration and repair. Go-to-market is enterprise sales-led, with dedicated inquiry portals and customer-only systems for testing/certification and calibration, supported by a phone-based customer support line (031-645-6300). The company maintains wholly-owned regional subsidiaries — HCT America Inc. in Milpitas, California (with separate test and calibration lab facilities) and PT. HCT Indonesia in East Jakarta — plus the H&H BIO affiliate for bio-related services. Named customers span global automotive OEMs (Hyundai, Kia, Renault Korea, KGM, VW, Tesla, Volvo, Stellantis), Korean automotive tier-1 suppliers (Hyundai Mobis, Motrex, Hanon Systems, Hyundai Kefico, Schaeffler Korea), electronics manufacturers (LG Electronics, LG Innotek), defense contractors (Lockheed Martin F-35 support), medical device manufacturers, and battery and energy storage system producers.
