Does this mean that the government is subsidizing the biodiesel manufacturing so that 

    they can sell to the export market for less than they sell it for in the home market?

Or that the company is selling for less in the export market to reduce inventory, or just cover overhead. 

Isn't that what dumping is?

Peru places anti-dumping tariffs on imports of biodiesel from Argentina

Peru is the latest country to place anti-dumping tariffs on imports of biodiesel from Argentina for a period of five years, after complaints of unfair competition, the South American’s market regulator said.

According to Reuters, Peru, the second-largest export market for Argentine biodiesel, passed the measure "to prevent the imports of the biofuel to continue harming national production," said the competition regulator Indecopi.

Under the instruction, different companies will be charged different rates, with the Argentine subsidiaries of Cargill, Bunge and Noble being charged $134.70 (€123.44) per tonne, $141.40 per tonne, and $152.70 per tonne, respectively. Louis Dreyfus, along with others, will be charged the highest rate of $191.60.

According to Reuters, the Argentine Biofuels Chamber called the rule a "protectionist measure against the World Trade Organization's (WTO) international norms" and said it would take legal action to force the Peruvian government to reverse its decision.

"We are the main supplier of biodiesel for Peruvian transport, and this unjustified decision will have consequences for their economy since domestic prices for fuel will rise," said Luis Zubizarreta, the group's president.

Argentina and Indonesia were responsible for about 90% of the Biodiesel imports of the European Union (EU) in 2012. By mid-2012, the EU accused Argentina and Indonesia of dumping their Biodiesel in the EU.

In 2013, the EU imposed definitive anti-dumping duties on imports of biodiesel from Argentina and Indonesia.

However, in September 2016, a European Union court annulled anti-dumping tariffs the bloc had applied to Argentine biodiesel imports, after the WTO ruled in favour of the South American country, calling the measures protectionist. Court cases are still continuing on the matter.
