ZHUJIAJIAO, CHINA (WASHINGTON POST) - The cost of pig feet was climbing, and Ms Xu Min wondered: Had the trade war reached her market stall?
The 29-year-old mother of two sells every part of the hog in a town known for braised hoofs, a classic snack here called trotters.
She carves the meat for local vendors, who slather the feet in soy sauce and hawk them along a nearby canal for as little as 15 yuan, or about S$3.
Geopolitical sparring does not come up often at this market of fresh cuts, watermelon crates and crabs wriggling in plastic bags, Ms Xu said, but lately she and other merchants have swapped grim predictions about the commercial fight between the United States and China.
"Importing less American pork will bring up the prices," the butcher said, frowning behind her bloodstained counter. "Fewer people will be buying - a bad effect."
The first signs of trouble from President Donald Trump's tariffs on US$34 billion (S$46.32 billion) in Chinese goods - and Beijing's retaliatory levies on an equal amount of US imports, including pork and soybeans - are just emerging in both countries, where some workers are bracing for economic turmoil.
Foreign swine that arrives frozen in Shanghai and other port cities is crucial to Ms Xu's business, she said, even though she purchases pork from local farmers.
The imports roll in on refrigerated trucks to warehouses across China, bolstering the national supply, she said, and helping to keep her costs low.
"Things are getting more expensive," she said, noting that her supplier had asked for a few extra yuan over the past two weeks.
The latest round of 25 per cent duties, which took effect in early July, is expected to shrink US exports to China, the fourth-biggest buyer of American swine and the world's largest pork consumer.
China bought 309,000 tonnes of pork last year from farmers throughout the Midwest and the South, and a lot of the shipments carried parts that many Americans don't normally eat: heads, tails, guts and feet.
The United States was China's top foreign supplier of these "variety meats" last year, with US$874 million in sales, Chinese customs data shows. (Germany ranked No. 2.)
The deal is a boon for American producers. Chinese buyers pay a premium for the hoofs, which are considered a delicacy and even a beauty booster - collagen in the fatty flesh is supposed to help make skin glow.
But the new tariffs could severely jeopardise this Sino-American arrangement, landing on top of another 25 per cent duty China imposed on American pork in April in response to levies that Mr Trump placed on Chinese steel and aluminium.
Already, the US loads of pork variety meats to China have diminished, according to the most recent export data, from 12,354 tonnes in March to 11,095 tonnes in April to 9,071 in May.
"We are looking at an US$800 million loss on variety meats alone," said Mr Joel Haggard, senior vice-president for the Asia-Pacific region at the US Meat Export Federation, a trade association. "It's brutal."
The damage is harder to measure in China, where the official line is: We can handily replace these outside goods with homegrown livestock.
Industry observers, though, say the country should protect its trade alliances to meet the growing demand from the exploding middle class.
The cost of pork overall in China has increased 10 per cent since May, according to the Agriculture Ministry, which does not release corresponding price data on variety meats.
However, the price of pig heads, tails and feet in the eastern province of Shandong jumped 7 per cent from May to late July, said Mr Barney Wu, an analyst at Guotai Junan Securities in Shanghai.
"The trade war has begun to hurt," Mr Wu said. "No one gains."
Even Mr Rogers Pay, an agriculture analyst at a Beijing consulting firm called China Policy, said the swelling price of soybeans, another tariff-affected commodity, could also increase expenses for sellers.
"Most of that soy is for pig feed," she said.
On the trade warpath, Mr Trump has shown no sign of backing down, threatening in July to impose duties on an extra US$200 billion in Chinese products.
The President has said he aims to close the United States' US$376 billion trade deficit with China and pressure the Asian nation to scrap policies that force US firms to divulge their proprietary secrets if they want to enter the Chinese market.
This escalation has startled vendors such as Ms Xu, who wants the spat to be resolved.
Pig feet, tails and ribs support her five-year-old daughter and seven-year-old son.
Pork allows her to pay their monthly rent of 500 yuan.
"I have no choice but to take it," Ms Xu said of trade war-related fluctuations. "This is all I can do."
One aisle over, another butcher said he was happy to absorb a loss for the good of his country.
Mr Gao Jun Gui, 56, has sold pig feet to local stands here for five years. His supplier lifted prices by 2 per cent in July, he said, and he suspects the tariffs have something to do with it.
"I'll earn a little less for now, but in a battle we will definitely win," the shirtless merchant said. "Trump is simple like a three-year-old - always changing his mind."
This could be an opportunity for China to reduce its reliance on outsiders, he added.
Across town, one of the market's regular customers brushed sweet, reddish sauce on her domestically produced trotters and displayed them on steel trays in a shop window.
Ms Wu Lin, a 45-year-old stall owner in clear jelly sandals, doesn't think the US tussle with China could jeopardise a treat this juicy.
Tourists from Asia, Africa, South America - "everywhere," she said - come to try it.
"My local pork tastes better than the frozen stuff," she said, "and I think it's more hygienic."
But in Qibao, south of Shanghai, another pork foot dealer in a Hello Kitty apron said the food company she partners with recently made a significant change: Six days before Mr Trump's first tariffs were scheduled to begin, the business stopped sending her imports.
She doesn't know what that means for the future of her business, the Most Nostalgic Shop.
"We used to get a mix of the local and frozen product," said Ms Xiao Lu, 40. "It changed because of the tariffs."
