U.S.-headquartered manufacturers that make their systems in American plants.
Springfield, Missouri
A Missouri manufacturer that formulates its coatings and builds its own spray rigs under one roof, and trains and supports a network of applicators.
St. Louis, Missouri
One of the largest privately held polyurethane systems houses in the country, producing its resins in St. Louis since 2004.
Santa Fe Springs, California
A family-owned California formulator with three U.S. plants, growing through acquisitions such as E-Z Flow Foam Systems in 2024.
In their words: American-made manufacturing
Why it matters
Chinese coatings and polyurethanes now carry up to 37.5% in Section 301 tariffs on top of normal duty, and Chinese MDI faces dumping duties of 87% to 162%. Systems made here don't pay those duties at the border.
When the Strait of Hormuz closed in 2026, global MDI prices jumped about 40%, while U.S. export prices rose about 10%. Domestic production is a buffer against shocks overseas.
Federal Buy American rules require 65% domestic content today and 75% from 2029. Federal highway projects now need more than 55% domestic components for manufactured products.
American manufacturers can show where a system is blended and where key inputs come from, and the FTC is cracking down on false Made in USA claims.
Tariffs in 2026
The Supreme Court struck down the IEEPA tariffs in February, but Section 301 duties, a new antidumping order on Chinese MDI and tougher Buy America rules all point the same way: toward coatings made in the United States.
Read the tariff trackerCoatings, polyurethanes and polymeric MDI pay a 25% legacy Section 301 tariff plus 12.5% since July 24, 2026.
U.S. producers held 82.7% of the U.S. MDI market in early 2025, and BASF is doubling its Louisiana MDI plant to 600,000 metric tons a year.
