The White House put a $303B number on tariff evasion. Read it as an audit notice

The White House Office of Trade and Manufacturing Policy released a 25-page report on August 13 titled "The Great Transshipment Scam," alleging that China has built a shadow network routing exports to the United States through roughly 40 countries where goods are relabelled, repackaged, reinvoiced or lightly assembled before re-export ^[1]. For importers, the operative content is not the rhetoric but the geography: the report names specific industrial districts, which is how enforcement targeting gets built ^[13][14][15].

The headline figures do not sit comfortably together. The report puts illegal transshipment at as much as $303 billion a year and the resulting federal revenue loss at $19 billion to $26 billion ^[2][3]. That implies an effective evaded duty of only about 6.3 to 8.6 percent ^[8], which is hard to square with the report's own claim that the average US tariff on Chinese products is around 50 percent ^[6]. Even at the roughly 23 percent average the Penn Wharton Budget Model measured earlier this month, $303 billion of evaded volume would imply about $70 billion in lost duty, close to triple the top of the administration's estimate ^[7][9]. The report also asserts 450,000 displaced jobs and $113 billion to $150 billion in annual GDP damage, which is 4.3 to 7.9 times the revenue figure ^[4][10].

Outside estimates suggest the leakage is larger than the report concedes. Customs data from China and the US Census Bureau showed a $112 billion gap last year between what China reported shipping and what the US reported receiving ^[5]. Goldman Sachs calculated that the US lost $110 billion to $130 billion to tariff dodgers during Trump's first term, after 2018 duties on more than $250 billion of Chinese goods ^[11][12].

The causal chain is not disputed by the practitioners. "If your tariff was 0% there's no need to commit fraud," Flexport chief executive Ryan Peterson told Fortune, adding that higher rates create an incentive to lie about valuation, classification or country of origin ^[16]. Carrie Owens, a Kelley Drye partner and former head of CBP's Enforcement Operations Division, told Fortune transshipment is a bigger issue now because tariffs are higher across the board ^[17].

The named districts show what the compliance burden will look like. The report singled out the Gyeonggi semiconductor belt of Pyeongtaek, Yongin and Icheon as a route for Chinese chips, and said US industry in Phoenix, Austin, Portland and San Jose was harmed ^[13]. Yet the category cited, "other integrated circuits," accounted for $41.4 million of Korean semiconductor exports to the US in the first half, or 2.8 percent of the $1.479 billion total, according to the Korea International Trade Association ^[18]. Myongji University's Kim Tae-hwang said additional tariffs on all semiconductors would be hard to justify on that basis, but that proof-of-origin requirements on goods and intermediate products containing chips would raise costs ^[19]. Mexico's Guanajuato-Queretaro corridor, Ho Chi Minh City and Pune were named for motors, switching devices and pumps ^[14][15].

Meanwhile the incentive keeps widening. Trump's August 13 drone proclamation sets 100 percent on drones over 25kg or with thermal imaging, effective September 3, and 15 percent for Korea, the EU, Japan, Taiwan, Switzerland and Liechtenstein only if substantially all hardware, software and technology originates there ^[20][21][22]. That is an 85-point spread policed by paperwork ^[23].

Watch for origin-verification demands on intermediate goods, clearance delays at named ports, and whether CBP's enforcement staffing moves before the 25 percent small-drone tier lands on February 9, 2027 ^[19][21].
