What Teijin Advanced Composites America makes

Teijin Advanced Composites America, Inc. (TACA) is the US arm of Teijin's carbon fiber composites business. The company was established in December 2011 to market and develop applications for carbon fiber reinforced thermoplastic (CFRTP) composites, and it operates the Teijin Composites Application Center (TCAC) in Auburn Hills, Michigan. The work is materials and application engineering rather than high-volume part production: TACA develops how a composite is designed, formed, and qualified into a program, then hands molding to Teijin's production sites.

Its flagship material is Sereebo, a carbon fiber reinforced thermoplastic that Teijin brands as the first CFRTP suited to high-volume automotive use. Sereebo uses chopped carbon fiber, roughly 20 mm long, in a nylon-6 matrix, compression-molded in about one minute. Teijin states the material is 40 percent lighter than steel, offers up to ten times greater impact resistance, resists corrosion, and is fully recyclable. The one-minute cycle is the point that matters to a buyer: conventional carbon fiber thermoset parts cure far too slowly for a mass-market vehicle line, and the fast cycle is what let a composite move onto a truck built in the hundreds of thousands. Teijin also markets Sereebo P sheet products for broader mobility applications.

TACA sits in the OEM automotive supply base as a material and application developer, upstream of the Tier 1 molders who produce finished parts. For buyers evaluating lightweighting, that distinction matters: the material qualification, the PPAP path, and the tooling all trace back to how the composite was engineered, which is the layer TACA works in.

Flagship program: the GMC Sierra CarbonPro box

The clearest public proof of the material is the GMC Sierra CarbonPro pickup box. Introduced on the 2019 GMC Sierra Denali 1500 and AT4 1500, it was the world's first use of CFRTP for structural parts in a high-volume production vehicle. The box is roughly 25 percent lighter than a steel bed, removing about 60 pounds of mass, and GM marketed it for dent, scratch, and corrosion resistance. The Sereebo material was developed by Teijin; the CarbonPro panels were molded by Continental Structural Plastics, now Teijin Automotive Technologies, at its Huntington, Indiana facility. Continental Structural Plastics and Teijin jointly won a 2020 Automotive News PACE Award for the box and took top honors at the 2019 SPE Automotive Innovation Awards.

The program is now winding down. In 2026, GM Authority reported that the 2027 GMC Sierra will not offer the CarbonPro bed, ending the option after the 2026 model year. That is a real change to the material's most visible application, and any buyer weighing Sereebo should read the CarbonPro history as a proof of concept for high-volume CFRTP rather than as an active, growing volume program.

Ownership and history

TACA is a subsidiary of Teijin Limited, a Japanese materials, healthcare, and fibers group listed in Tokyo (TSE: 3401) and founded in 1918. For the fiscal year ended March 31, 2025, Teijin Limited reported group revenue of about 1,005.5 billion yen and roughly 21,834 employees across the group. Those are group figures; Teijin does not publish standalone financials or headcount for TACA, which is a small application-development center rather than a reporting segment.

Teijin's US composites footprint spans several entities. TACA and the TCAC handle CFRTP materials and application development in Auburn Hills. Teijin Carbon America produces Tenax carbon fiber in Greenwood, South Carolina. Teijin Automotive Technologies, the former Continental Structural Plastics that Teijin acquired in 2017, is the group's North American molder of composite automotive parts and is also headquartered in Auburn Hills. These are related but distinct companies, and a buyer should confirm which entity holds a given contract.

Known customers

Most of TACA's application work is not publicly named, which is normal for a materials developer supplying OEM programs. One relationship is well documented.

Sourcing evidence

TACA does not appear as a distinct US importer in customs bill-of-lading records. A search of public import data returns a separate Teijin entity, Teijin Frontier USA, a fibers and textiles subsidiary in New York, rather than the Auburn Hills composites company. Rather than attribute another subsidiary's shipments to TACA, this profile leaves the customs panel empty.

That absence is not unusual for an application-development center. TACA's role is materials and engineering, not container-scale import of finished goods, so a light or absent customs footprint is consistent with what the company does. Buyers assessing Teijin's broader composite supply chain, including nearshoring and tariff exposure, should look at the group's production entities, Teijin Automotive Technologies and Teijin Carbon America, where the physical part and fiber volumes sit.

Coverage caveat: US customs records cover ocean freight and name the importing entity as filed. A subsidiary that develops materials rather than importing finished parts can be legitimately absent from that record. Absence of a record is not evidence of absence.

Frequently asked questions

What does Teijin Advanced Composites America make?

Teijin Advanced Composites America (TACA) develops carbon fiber reinforced thermoplastic (CFRTP) composite materials and applications. It markets Teijin's Sereebo material, a chopped carbon fiber and nylon composite that molds in about one minute, and operates the Teijin Composites Application Center in Auburn Hills, Michigan. The finished parts are molded by other Teijin production companies.

Who owns Teijin Advanced Composites America?

TACA is a subsidiary of Teijin Limited, a Japanese materials, healthcare, and fibers group listed in Tokyo (TSE: 3401) and founded in 1918. Teijin established TACA in December 2011.

Who are Teijin Advanced Composites America's customers?

The best-documented customer is General Motors. Teijin's Sereebo CFRTP was used for the GMC Sierra CarbonPro pickup box, announced for production in May 2019 and recognized with a 2020 Automotive News PACE Award. GM Authority reported in 2026 that the CarbonPro option ends after the 2026 model year.

Where is Teijin Advanced Composites America located?

TACA is at 1200 Harmon Road, Auburn Hills, Michigan 48326, where it runs the Teijin Composites Application Center. Auburn Hills is also home to Teijin Automotive Technologies, a related Teijin composites company.

What is Sereebo?

Sereebo is Teijin's carbon fiber reinforced thermoplastic. It uses chopped carbon fiber, about 20 mm long, in a nylon-6 matrix, compression-molded in roughly one minute. Teijin describes it as 40 percent lighter than steel, with up to ten times the impact resistance, and fully recyclable. Its first high-volume application was the GMC Sierra CarbonPro box.

Does Teijin Advanced Composites America publish financials?

No. TACA is a small application-development center and Teijin does not report standalone revenue or headcount for it. Its parent, Teijin Limited, reported group revenue of about 1,005.5 billion yen for the fiscal year ended March 31, 2025.
