WASHINGTON, May 14 (Reuters) - President Joe Biden is hiking tariffs on $18 billion in Chinese goods including electric vehicles, batteries, semiconductors, steel, aluminum, critical minerals, solar cells, ship-to-shore cranes, and medical products, while retaining Trump-era tariffs on over $300 billion in goods.The United States Trade Representative's Office told Reuters it anticipates the effective date will be in approximately 90 days.

The following products will be targeted:
* Certain steel and aluminum products: Tariffs more than triple on some these products, estimated earlier at least $1 billion in goods, from the current range of zero to 7.5% to 25% in 2024. The White House cited "China's non-market overcapacity in steel and aluminum, which are among the world's most carbon intensive."

* Semiconductors: Tariffs will increase from 25% to 50% by 2025, the White House said, citing China's huge share in new semiconductor wafers coming online and a spike in prices during the pandemic. "China's policies in the legacy semiconductor sector have led to growing market share and rapid capacity expansion that risks driving out investment by market-driven firms."

* Electric Vehicles: Tariffs will increase from 25% to 100% in 2024 (on top of a separate 2.5% tariff), the White House said, citing "extensive subsidies and non-market practices leading to substantial risks of overcapacity." The U.S. Trade Representative's Office said plug-in hybrid electric vehicles will be covered by the new tariffs but not hybrid vehicles.
* Batteries, Battery Components and Parts: Tariffs on lithium-ion EV batteries will increase from 7.5% to 25% in 2024, while the tariff rate on lithium-ion non-EV batteries will increase from 7.5% to 25% in 2026. Tariff rates on battery parts will increase from 7.5% to 25% in 2024. Critical minerals: Tariffs for certain critical minerals will increase from 0 to 25% in 2024.
