The World Trade Organization is to investigate claims that the US is imposing illegal tariffs on imported orange juice and lumber. The WTO's Dispute Settlement Body has decided that a panel of experts will examine the issue, following complaints from Brazil about a tax imposed by the State of Florida on orange and grapefruit juice. Their deliberations usually take around one year to complete.

Florida has applied the tax, currently around 3 cents a gallon, on imported concentrate, which is added to orange juice produced in Florida for flavour and colour and to make up for short supply, for 32 years.

All foreign suppliers, from countries such as Costa Rica, Mexico and Brazil, have to pay the levy. Recently, Florida has also begun imposing the tax on concentrate imported from other US states.
