Tesla, Samsung oppose US tariffs on Vietnam as steel and solar firms seek penalties

U.S. businesses are split over whether Washington should impose additional tariffs on Vietnamese goods as the Trump administration approaches a November 29 deadline for its investigation into alleged intellectual property violations. Tesla and Samsung, along with trade groups representing companies that manufacture in Vietnam, warn that new duties could disrupt supply chains and raise costs; Tesla says some advanced components and equipment are not available from U.S. suppliers. U.S. steel, seafood, plywood, solar, wood and software interests have urged tougher action, citing alleged unfair practices and weak intellectual-property enforcement. Vietnam, which the U.S. has placed on its most serious intellectual-property watchlist, has called for objective investigations; a separate inquiry into alleged excess industrial capacity is also underway.
