TH Plastics has two other facilities in the area, one in Findlay (2010) and one in Bowling Green (2013) that manufacture and assemble products for a variety of customers in the Midwest. Construction is scheduled to be completed in summer 2021 and production will begin shortly after. TH Plastics was founded in 1974 by Ted Haas in Mendon, Michigan, which is the site of the company’s headquarters and first manufacturing plant. 

Tiffin-Seneca Economic Partnership, the Regional Growth Partnership and JobsOhio worked closely with TH Plastics to secure the project, which will receive Roadwork Development (629) assistance from Development Services Agency and Ohio Department of Transportation Jobs & Commerce funds. Local incentives include the City of Tiffin’s New Jobs Program, property tax exemption through a pre-exiting Community Reinvestment Area and OhioMeansJobs-Seneca County is offering up to $330,000 in potential workforce development grants. These incentives are contingent upon approval of Tiffin City Council.

The spec building was constructed in 2018 by Clouse Construction in coordination with Tiffin-Seneca Economic Partnership, then Seneca Industrial and Economic Development Corp., on an 11.3-acre site that had been owned by the City of Tiffin. Previous speculative industrial building initiatives by SIEDC include the building that now houses MBDS, 981 Tyber Road, built in 2006, and the Quick Tab II facility, 241 Heritage Drive, built in 1994.

“I am excited to be able to welcome TH Plastics to Tiffin and Seneca County,” said Tiffin Mayor Aaron Montz. “Even in the face of this pandemic, Tiffin continues to be a city that companies are coming to and growing in, and I could not be more proud to represent this resilient community.”
