ZJK Industrial Co., Ltd. is a high-tech enterprise that manufactures and sells precision fasteners, structural parts and other precision metal components for new energy vehicles and intelligent electronic equipment such as mobile phones, smart watches, drones and 5G communication base stations. The company operates through its consolidated subsidiaries in the People's Republic of China, including Zhongjinke Shenzhen, Zhongke Components, Zhongjinke Nanjing, PSM‑ZJK and Precision Vietnam. As of the date of the annual report, ZJK employs 542 personnel and holds 63 patents from the China National Intellectual Property Administration. It has adopted ISO 9001:2015, ISO 14001:2015, IATF 16949:2016 and ISO 45001:2018 certifications to ensure quality, environmental, automotive and occupational health standards. In the fiscal years ended December 31, 2024 and 2025, the company produced approximately 5.7 billion and 9.7 billion precision metal parts, respectively. Its research and development team consists of 33 engineers, of whom five have more than ten years of experience and six have more than five years of experience.

ZJK generates revenue primarily through a direct sales model, with its sales department handling customer contact, product sales, after‑sales service and customer maintenance. The company’s product portfolio includes standard screws, nuts, bolts, turning parts, stamping parts and computer numerical control (CNC) machining parts, which are used in new energy vehicles, mobile phones, smart watches, drones, 5G base stations and other electronic equipment. Revenue is derived from the sale of these components to OEMs and contract manufacturers, with the sales team engaging customers early in the product development process to co‑design solutions. ZJK maintains both China‑based and overseas sales teams and has entered into sales representative contracts with seven teams in North America to expand its presence there. In April 2024 the company established a factory in Vietnam and in November 2025 it signed a strategic cooperation framework with Chaince Digital Holdings Inc. to jointly create a Delaware‑based joint venture for a planned precision components R&D and manufacturing Gigafactory in the United States.

ZJK positions itself as a specialized supplier of precision metal parts within the competitive fasteners and components industry, emphasizing efficient production organization and high product quality as core advantages. The company cites strong research and development capacity, solid customer relationships and an experienced management team as additional competitive strengths that differentiate it from rivals. Its core technologies include advanced stamping dies for solder chip nuts, ultra‑thin gasket molds for drones, and precision screw processing tools, which improve yield, reduce costs and enable mass production. However, ZJK acknowledges challenges including its relatively small scale compared with larger competitors and the need for external financing to support continued growth.

ZJK serves original equipment manufacturers (OEMs) and other enterprises in the consumer electronics, new energy vehicle and related sectors, supplying components that go into products such as phones, watches, drones and telecommunications infrastructure. While the filing does not disclose specific customer names, it notes that the company has become a supplier for several well‑known enterprises and their OEM partners. The customer base includes both domestic Chinese firms and international clients supported by the company’s overseas sales teams and North American sales representative agreements. ZJK also works with customers from the outset of research and development to tailor products to specific performance and design requirements.
