Trading to Win
Manufacturers are offering a clear, actionable agenda to strengthen U.S. manufacturing through common-sense trade policy:
-
1
Go for Zero-for-Zero Tariffs
We’re calling on negotiators to secure better terms for manufacturers by adopting zero-for-zero tariffs for American-made products in our trading partners’ markets. That means they don’t charge us, and we don’t charge them.
-
2
Protect Inputs That Power U.S. Production
More than half of U.S. imports are manufacturing inputs. These include critical minerals, chemicals and machinery essential for making things in America. On the path to zero-for-zero, we urge negotiators to take out of scope specific manufacturing inputs we need to make things in America.
-
3
Create American Investment Incentives
If tariffs remain in place, we propose specific incentives, such as tariff rebates for manufacturing companies investing in manufacturing in the U.S. to accelerate the growth of the American industrial base.

What Manufacturers Are Saying on Tariffs
The Promise of the USMCA
President Trump’s USMCA succeeded in shifting manufacturing imports away from China to North America. In this new phase of U.S. trade policy, strengthening the United States–Mexico–Canada Agreement will be critical in helping North America restore balance and combat disruptive, problematic trade practices coming out of other countries, specifically China.
