Indian authorities are investigating LG Electronics and Samsung Electronics over whether the companies paid the correct tariffs on imported OLED television components, five people familiar with the matter told Reuters.

The inquiry concerns how display parts were classified for customs purposes. An investigation does not establish that either company violated the law, and any final liability would depend on the authorities' findings and appeals process.

India has been encouraging more electronics manufacturing inside the country while using tariffs and incentives to influence supply-chain decisions by global manufacturers.
