If the United States accepts the offer Japan has made as part of the ongoing Trans-Pacific Partnership trade talks, it would be a "radical departure from previous U.S. free trade agreements," suggests a group of meat and grain groups.
The offer, they added, would set "an unacceptable precedent for future trade deals" if accepted.
The TPP is a regional trade negotiation that includes the United States, Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam, which account for nearly 40% of global GDP.
In its negotiations with the United States, Japan wants to exempt from tariff elimination 586 tariff lines, or 11% of its tariff schedule. In the 17 other FTAs the United States has concluded this century, only 233 tariff lines were exempted from tariff elimination.

"For the TPP to be a high-standard, 21st century agreement, Japan's deal on market access should exceed the deal that South Korea and other U.S. FTA partners made this century with the United States," said Nick Giordano, vice president and international trade counsel for the National Pork Producers Council, which is part of the groups leading the charge against the deal.
"If the United States acquiesces to Japan's demands," Giordano said, "it's not difficult to envision other trading partners asking for exemptions on non-agricultural products. And if Japan is permitted to shield a massive number of tariff lines from tariff elimination, other TPP countries are likely to pull back their sensitive products."
Japan is an important market for U.S. agriculture – the fourth largest – which shipped $13.5 billion of food and agricultural products to the island nation in 2012.
"The U.S. must reject Japan's offer and insist that it do what every other U.S. trading partner has done and what all other TPP nations are willing to do: eliminate all tariffs," Giordano said.
The American Meat Institute, National Pork Producers Council, National Cattlemen's Beef Association, National Association of Wheat Growers and U.S. Wheat Associates were among the groups responding to Japan's TPP offer.
