What Henniges Automotive makes

Henniges Automotive is a global Tier 1 supplier of highly engineered automotive sealing and anti-vibration systems. Its core product lines are the rubber and TPE sealing systems that run around a vehicle's openings: doors, windows, trunks, lift gates, sunroofs, and hoods. Alongside sealing, the company produces encapsulated glass systems, anti-vibration components, and related rubber parts. These are the parts that control how a door shuts, how much wind and water intrude at speed, and how much road noise reaches the cabin, so warranty rates and customer feedback are the metrics that matter, and the company points to both as evidence its parts outperform.

Henniges supplies automotive OEMs directly, both large blue-chip carmakers and smaller technology-driven manufacturers. The company describes its platform as vertically integrated, which gives it the ability to make large-volume premium products with consistent quality across regions rather than outsourcing sub-processes. Sealing and encapsulated glass apply across both internal-combustion and electric-vehicle programs, so the product set carries into the EV transition without a change in what the company builds.

Ownership and history

Henniges traces its lineage to 1863, making it one of the older names in the automotive supply base. Its modern corporate form has passed through several owners. Private-equity firm Littlejohn & Co. acquired the business in 2013. In 2015, AVIC Automotive Systems Holding Co., Ltd., a subsidiary of Aviation Industry Corporation of China, acquired Henniges outright, a deal AVIC described as one of the largest acquisitions of a US automotive manufacturer by a Chinese company to date. The transaction cleared a CFIUS review, and in 2019 the Senate Finance Committee asked questions about that approval given AVIC's state ownership. Henniges has operated as an AVIC portfolio company since.

The company's world headquarters is at 2750 High Meadow Circle in Auburn Hills, Michigan. Larry Rollins serves as President, having joined Henniges in 1988 and risen through manufacturing, plant management, and global operations, including a term as Chief Operating Officer. Linda Hellebuyck is Chief Financial Officer, and Adam Koivula, who rejoined the company in 2025, is Global Vice President of Sales.

Global footprint

Henniges runs roughly 18 facilities across North America, Europe, and Asia, with about 8,000 employees worldwide. In the United States it operates plants in Keokuk, Iowa; New Haven, Missouri; Reidsville, North Carolina; and Frederick, Oklahoma, in addition to the Auburn Hills headquarters. Mexico adds four sites, in Gomez Palacio, Guadalajara, and Torreon. In Asia the company has five Chinese facilities, in Beijing, Guiyang, Shanghai, Taicang, and Tieling. Europe is served from Hranice in the Czech Republic and Prudnik in Poland, with a European headquarters and technical center opened in Mlada Boleslav, Czech Republic, in 2020. The company closed its Burlington, Ontario plant at the end of 2024.

Certifications and quality

Henniges states that its operations hold IATF 16949, the automotive quality-management standard, along with ISO 14001 for environmental management and ISO 45001 for occupational health and safety. Multi-site IATF 16949 registration is the norm for a Tier 1 of this scale, and the company reports it as a standing claim across its manufacturing base. On sustainability, Henniges earned an EcoVadis Bronze Medal for the fourth consecutive year in its January 2026 assessment, improving its percentile ranking from the 52nd to the 69th, which places it among the top 35 percent of companies EcoVadis assesses.

Known customers

Most of Henniges' OEM relationships are unnamed, which is normal for a direct sealing supplier. One is on the public record through a repeated program award.

Beyond that documented relationship, the company describes long-standing ties with blue-chip OEMs and smaller technology-driven manufacturers, and it sells to all major automotive OEMs. Those broader claims are the company's own and are not individually named here.

Sourcing evidence

Henniges' US import record reads like a manufacturer bringing in production materials, not a reseller moving finished goods. US customs bill-of-lading records show 501 sea shipments since January 2015, with the most recent on record dated August 2, 2026, and volume averaging about 8.13 TEU per month. The single largest foreign supplier by shipment count is Fuyao Glass Industrial Group, the world's largest automotive glass maker, which fits a company that builds encapsulated glass modules and glass-run sealing.

Four shown of the recorded supplier list. The mix, automotive glass and technical films in, sealed assemblies out, is the signature of a plant that imports substrates and consolidates them into finished sealing and glass modules domestically. The company also imports under dozens of name and address variants across its US plants, so a single importer record understates the true flow.

Coverage caveats: these are US ocean-freight records only. Air, truck, and rail movements do not appear, some records name freight intermediaries rather than manufacturers, and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
