What BHAP makes

Beijing Hainachuan Automotive Parts Co., Ltd. (BHAP) is a diversified Tier-1 automotive supplier that spans five major product domains: interior and exterior systems, electronics and electrical systems, chassis, powertrain, and body components. The company operates through more than 100 member enterprises, each focused on a distinct product category.

In the interior and exterior segment, BHAP produces front and rear bumper assemblies, seat modules, cockpit systems, instrument panels, door trim panels, and front-end and tail-door modules. Its electronics portfolio includes vehicle lighting, high- and low-voltage wire harnesses, air conditioning systems, central intelligent gateways, 4G T-BOX modules, and intelligent driving system hardware. Chassis products cover transmission systems, chassis modules, steering assemblies, wheel hubs, and brake systems.

Powertrain is a growing focus. Member enterprise Bohai Piston is a documented manufacturer of pistons and cylinder components; in January 2026, Bohai Piston announced China's first Euro 7-specification forged steel piston. BHAP also produces dedicated hybrid transmissions (DHT), battery boxes, fuel tank assemblies, intelligent transfer cases, and spiral bevel gears.

The electrification segment is now a stated strategic priority. BHAP's DHT assembly targets peak drive power of 150 kW at 350 V. Its EDU (electric drive unit) assembly supports BEV, PHEV, HEV, and REEV vehicle architectures, with distributed drive capability for complex maneuvers. Motor products cover voltage ranges of 400 to 900 V and peak outputs of 200 to 300 kW. BHAP also develops motor controllers, domain controller units (DCU), high-definition cameras, and millimeter-wave radar for intelligent driving applications.

On the materials side, BHAP works with high-strength steel structures and multi-material composite cockpit cross-beams (CCB) under its lightweight initiative.

Financial performance

BHAP reported annual operating revenue exceeding RMB 70 billion for FY2025, placing it 34th among global automotive parts suppliers per the company's own disclosure, up from 43rd in 2024. It ranks 4th in China's automotive parts sector. The Berylls Automotive Suppliers Top 100 (2026 edition, covering FY2025 automotive-sector revenue) estimates revenue at approximately EUR 8.6 billion, with a 4.1% year-over-year decline from an estimated EUR 9.0 billion in FY2024. Berylls classifies the figure as an external estimate; BHAP does not publish a standalone audited financial report as it is an unlisted subsidiary of BAIC Group. No EBIT margin or operating income figure is publicly disclosed.

The revenue softness is consistent with broader pressure on BAIC-dependent Chinese suppliers in 2024 and 2025, as BAIC Motor's domestic passenger-vehicle volumes came under competitive pressure. BHAP employs more than 30,000 people across its member enterprises, per the company's own figures. It holds more than 3,000 patents and operates 12 R&D centers, 9 CNAS-certified laboratories, and 12 municipal or higher-level technical centers. Ten of its plants have received state-level green factory certification.

Ownership and history

BHAP was founded in January 2008 as the automotive parts vehicle for BAIC Group (Beijing Automotive Group / 北京汽车集团有限公司), one of China's largest state-owned automotive conglomerates. BAIC Group is the parent organization; BHAP consolidates the group's Tier-1 auto parts businesses under a single management structure.

Headquartered at No. 7, Xinghai 3rd Road, Yizhuang Economic Development Zone, Daxing District, Beijing, the company has expanded to 9 countries since its founding. International presences include the Netherlands (Venray), the United States (Auburn Hills and Atlanta), Mexico (Irapuato), Germany (two locations), Poland (Wrzesnia), Slovakia (Krakovany), and South Korea (Mado). Within China, BHAP operates 67 production bases across Beijing, Shanghai, Shandong, Chongqing, Tianjin, Hebei, Jilin, Jiangsu, Jiangxi, Guangdong, Sichuan, Anhui, and Hunan.

The company has built approximately 20 international joint ventures with global parts suppliers. Documented partners include Adient, Aptiv, Lear, Visteon, BorgWarner, Tenneco, and Hella, as confirmed in industry databases. In October 2025, BENTELER Group announced the opening of a new module plant in Beijing as a joint venture with BHAP.

Known customers

BHAP's primary customer anchor is BAIC Group's own vehicle brands, given the parent-subsidiary relationship. The company states it supplies more than 40 global automaker brands across passenger cars, commercial vehicles, and new-energy vehicles. Specific program documentation for non-BAIC OEMs is limited in publicly available sources.

The company's joint venture structure provides indirect evidence of customer relationships. A joint venture with Adient implies seat module supply into Adient's OEM customer base. JV arrangements with Lear and Visteon point to harness and electronics supply chains. BHAP's own press materials cite serving "more than 40 world-leading automakers," which is plausible for a supplier operating at this revenue scale within the Chinese automotive ecosystem. Procurement teams should verify specific program details through direct engagement, as BHAP does not publish individual customer revenue breakdowns.
