Those different parts, known collectively as offal or "variety meats", had been a money-making export for US pig farmers in 2017 with $874 million in sales to China, the top buyer of US variety meats last year.
According to the USDA, US pork exports to Chinese mainland/Hong Kong from the beginning of this year through May were down 18 percent by volume and 6 percent by value. US exports likely continued to fall in June and July, particularly in July since the second 25 percent tariff was imposed on July 6.
"It's a real big blow to producers to lose the Chinese market because of the variety meats," Ken Maschhoff told USA Today. "It is a $30 million impact to our operation," he said, making up a third and as much as half his profit.
Variety meats make up as much as $5.25 to $5.50 in profit per hog out of the at least $10 per animal that producers need to remain profitable, according to Maschhoff. "I estimate the average hog farmer can only sustain the losses caused by tariffs up to two years," he said.
"The Chinese aren't going to get hurt by this," said Maschhoff, chairman of The Maschhoffs, "Chile or Europe or somebody else is going to say, 'Well, we've got a bunch of stomachs or livers or feet that we're not using...'"
