The White House has placed Pune, Gujarat and Chennai in an unusual group of manufacturing locations it calls ‘ugly sister cities’, pairing the Indian production belt with Cincinnati, Dayton and Columbus in US.
The comparison has nothing to do with traditional sister-city relationships. Instead, it is based on industrial competition. The
White House report The Great Transshipment Scam matches foreign manufacturing and trade corridors handling products considered vulnerable to Chinese tariff evasion with US industrial regions producing the same or similar goods.
For India, the reference is significant because it comes as Washington steps up scrutiny of whether Chinese goods are reaching US through third countries, including India, after being subjected to higher US tariffs when imported directly from China.
The report identifies India as a tier-1 ‘diversified scale leader’ within what it calls China’s ‘shadow transshipment network’. It groups India with Canada, the European Union (EU), Israel, Japan, Mexico, South Korea and Taiwan—economies with large manufacturing bases, substantial China-linked trade and significant exports to the US. The report stresses that transshipment risk in these economies is embedded within much larger legitimate trade flows.
The classification, therefore, does not amount to an allegation that Indian exporters as a whole are illegally avoiding US tariffs. Rather, Washington is flagging India as a major trading and manufacturing hub where legitimate commerce and potential China-linked transshipment can coexist.
Why Pune, Gujarat and Chennai Have Been Singled Out
The White House report's ‘ugly sister city’ table maps India's Pune-Gujarat-Chennai manufacturing belt to Cincinnati, Dayton and Columbus, with pumps and compressors under HS codes 8413 and 8414 forming the product category.
The idea is to show the possible factory-level consequences of trade diversion. If China-linked goods reach the American market through another country after their origin has been improperly obscured or altered, US manufacturers producing competing goods can lose orders and market share.
The report says its city pairings are not cultural or civic relationships. They are product-to-industry comparisons based on trade categories, manufacturing activity and the US industrial geography associated with those products.
The India-US comparison consequently puts a spotlight on the country's growing role in global industrial supply chains. Pune, Gujarat and Chennai are being viewed not merely as export centres but as manufacturing locations competing with established American industrial corridors.
The China-India-US Route Washington Is Examining
At the heart of the White House report is the possibility that higher tariffs on Chinese goods could create an economic incentive to route those goods through countries with lower US tariff burdens.
The report says illegal transshipment can involve practices such as changing invoices, relabelling, repackaging, minor processing or making misleading claims about the country of origin. The purpose, according to the report, is to obtain tariff treatment that would not have applied had the goods' actual economic origin been declared.
Washington says the pattern became more important after the US imposed Section 301 tariffs on China in 2018. According to the report, Chinese exports that previously moved directly to the US increasingly travelled through third countries where limited processing, repackaging or documentation changes could make the products appear to have a different origin.
The White House describes the resulting network as the ‘shadow transshipment network’ and says more than 40 countries have been associated with elevated transshipment risk.
India's inclusion is particularly notable because the report simultaneously recognises the country's substantial legitimate manufacturing base. That is why India is in the top tier rather than being categorised among the smaller economies that Washington describes as opportunistic targets.
US$67bn India-Mexico-Vietnam Estimate
One of the report's most striking figures comes from the US commerce department's office of trade and economic analysis.
Using a transaction-level methodology, the Commerce analysis estimates that around US$67bn (billion) of US-bound goods were transshipped from China through three major hubs—Mexico, India and Vietnam—in 2025. It estimates the associated loss of US tariff revenue at US$28bn.
That figure needs to be read carefully.
It is not presented as proof that US$67bn of Indian exports to the US were illegally routed goods from China. The methodology covers the three hubs collectively and attempts to identify potential transshipment through exact product matching. The broader White House report also repeatedly acknowledges that some of the increase in third-country trade represents genuine changes in production, investment and sourcing rather than illegal activity.
The commerce estimate is, nevertheless, important because India is one of only three hubs identified in that particular transaction-level analysis.
Genuine Indian Manufacturing Versus Origin Shifting
The distinction Washington is trying to make is between genuine production in India and the use of India merely as a route for Chinese goods.
The report describes production-side nodes where China-origin inputs may undergo light assembly, finishing, testing, packaging, labelling or component integration. It contrasts those activities with logistics-side operations such as warehousing, consolidation, documentation changes, re-invoicing and re-exporting.
That distinction could become increasingly important for Indian exporters.
An Indian factory legitimately using Chinese-made components is not automatically evidence of tariff evasion. The critical issue for US customs authorities is whether the manufacturing performed in India constitutes genuine production or substantial transformation, rather than merely providing a new route and a new set of documents for a largely China-made product.
The report says enforcement would therefore have to examine factory capacity, input sourcing, local value addition, labour use, equipment and whether the claimed transformation is substantive.
Why the White House Is Worried about Tariff Arbitrage
The economic incentive is straightforward. When a product imported directly from China faces a higher US tariff than the same product entering from another country, the difference can become a financial incentive to change the route. The White House calls this tariff arbitrage and argues that the tariff gap can be large enough to support processing facilities, logistics networks and other infrastructure designed to shift the apparent origin of goods.
The report says this pattern expanded following the 2018 China tariffs, as Chinese products increasingly moved through lower-tariff jurisdictions. It describes this shift as the ‘great reallocation’.
But the White House itself acknowledges that falling Chinese imports and rising imports from third countries do not automatically establish illegal transshipment. Some companies have genuinely moved production away from China or diversified their supply chains. The central question is how much of the shift represents legitimate manufacturing and how much reflects tariff evasion.
India Is Not Alone
The ‘ugly sister’ comparison involving India is one of several examples in the report.
Mexico's Guanajuato-Querétaro corridor is paired with Detroit, Grand Rapids and Indianapolis for electric motors, generators, transformers and related equipment. South Korea's Gyeonggi region is matched with Phoenix, Austin, Portland and San Jose for integrated circuits. Vietnam's Ho Chi Minh City is paired with Chicago, Milwaukee and Rockford for electrical switching and circuit-protection equipment.
The report similarly pairs Malaysia's Penang-Kulim cluster with US plastics-producing regions and Thailand's Ayutthaya-Samut Prakan corridor with Minneapolis-St Paul for thermostats.
The broader message is that Washington views transshipment not simply as a customs violation but as a potential source of competitive pressure on specific American manufacturing communities.
White House Estimates Vary Widely
The report brings together five estimates of potential transshipment exposure. Depending on the methodology, they range from about US$40bn to US$303bn a year.
The White House uses about US$75bn as a central estimate based on Exiger's analysis, while the Council of Economic Advisers estimate has a range of US$34.2bn to US$89.6bn. Commerce has a broader US$109bn trade-transfer benchmark, while Altana's US$303bn figure represents a much broader upper-bound exposure measure.
These numbers should not be added together. The report explicitly says the estimates use different datasets, methodologies and definitions and are therefore not directly comparable.
Using its central US$75bn scenario, however, the White House estimates around 450,000 US jobs could be displaced, along with US$113bn to US$150bn in annual GDP effects and US$19bn to US$26bn in federal revenue losses. These are model-based estimates, not observed job losses.
Washington Turns to AI To Track Suspicious Shipments
The report also outlines an artificial intelligence (AI)-enabled system called ‘detective border’, intended to give US customs and border protection greater ability to identify suspicious trade flows.
The system is designed to combine shipment data, routing histories, product classifications, company ownership information, production capacity indicators and anomaly detection. The objective is to separate genuine foreign investment and manufacturing from goods that are simply passing through another country.
The proposed technology would enable US authorities to compare what an exporter claims to manufacture with evidence of what its facilities can actually produce.
The report says AI tools could also examine bills of lading, shipping manifests, declared origins and component information to identify inconsistencies.
For Indian exporters, that could mean greater scrutiny of the entire supply chain rather than just the final country shown on an export document.
What It Means for India's Manufacturing Ambitions
The White House report comes at a sensitive point for India's manufacturing strategy.
India is seeking to expand its role in global supply chains as companies diversify production away from China. The US scrutiny creates both an opportunity and a risk.
If Indian factories are genuinely producing goods that previously came from China, the shift could strengthen India's position as a credible alternative manufacturing base. But if US authorities conclude that some exporters are merely providing a route for China-linked products, the same supply-chain diversification could attract additional customs checks.
The report's focus on Pune, Gujarat and Chennai is, therefore, significant beyond the pumps and compressors category.
The three Indian manufacturing centres have effectively been placed on a US map of industrial competition, where the question is not simply where a shipment was exported from but what happened to the product before it reached the US market.
The White House's own terminology captures the distinction: ‘ugly sister cities’ are not conventional sister-city partnerships but product and manufacturing pairings showing where foreign trade corridors could put pressure on corresponding American industries.
For Indian manufacturers, the immediate issue is likely to be supply-chain transparency. The more closely an exporter can demonstrate its manufacturing capacity, input sources and production processes, the easier it should be to distinguish genuine Indian manufacturing from the kind of origin-shifting activity Washington is targeting.
The bigger test for India is whether it can convert the global shift away from China into durable manufacturing capacity while keeping its export supply chains transparent enough to withstand increasingly sophisticated US scrutiny.
Washington's message is that a shipment leaving an Indian port will no longer necessarily end the questions about where the product came from. As the US builds its AI-driven ‘detective border’, the scrutiny is moving upstream—towards the factory, the components, the ownership structure, the shipping route and the actual transformation that took place before the goods reached America.
