The new tariffs on patented drugs come with lots of exceptions.

Drugmakers that reach pricing deals with the Trump administration or are at minimum building manufacturing facilities in the U.S.

can avoid the levies or pay only 20%.

and those in the E.U.

mean lower tariffs for drugmakers there.

As for the metal tariffs, changes are said to be focused on simplifying how they're collected and to combat cheating.

50% tariffs will be eliminated for products that contain small amounts of aluminum, steel, or copper.

They'll come down to 25% for most other products, such as household appliances.

But they'll now be assessed on the full value of the product, not just of the metal it contains.

In addition, the administration will now calculate levies on imports of the metals themselves based on what they're worth in the U.S.

The White House says some importers have been gaming the system with artificially low prices charged abroad.
