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 not to put tariffs on 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.

For every $1 of manufacturing inputs imported, manufacturers in America produce $1.40 of output.
U.S. suppliers have the capacity to meet up to 84% of U.S. manufacturers’ intermediate and capital goods needs. Even with full utilization of current industrial capacity, 16% of inputs must be imported. |

What Manufacturers Are Saying on Tariffs
Key Policy Actions
The NAM has made a series of recommendations through formal comments to federal agencies in response to the administration’s recent tariff policy proposals. The NAM cautions against broad tariffs that could disrupt supply chains, increase costs, and undermine the global competitiveness of our member companies, offering alternative paths to accelerate manufacturing in the U.S.
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.
