China‑plus‑one: Vietnam's 40% transshipment penalty tests sourcing

Market Context & Direct Impact

Vietnam now leads China-plus-one electronics flows to the U.S., yet core production of those goods stays in China. A Bloomberg analysis of shipment-level customs data found Vietnam passed China as the top U.S. source of laptops and game consoles in 2025. Core production of those electronics still happens in China. Vietnamese plants that assemble Chinese-made components added under 8% of export value in some cases. U.S. imports from a group including Vietnam, India and Mexico rose by a cumulative $49 billion while China's shipments fell $51 billion last year. The gap suggests Vietnam's gain rests on final assembly rather than full manufacturing.

A 40% transshipment penalty is the rule that can reset landed cost for goods routed through Vietnam. SCMP reports that the April 2025 executive order which set a 46 per cent duty on Vietnam also added a 40 per cent penalty on goods built mainly from foreign materials with only minor assembly elsewhere. That 46 per cent rate was later cut to 20 per cent, but with a catch. Section 301 probes into Vietnam's IP protection, capacity and labour practices are underway, and the sources reviewed report no outcome for them.

Core Executive Takeaways

• Price origin, not labelsA 40% penalty targets goods built mainly from foreign inputs, so a Vietnam label alone may not shield landed cost.
• Use India preferencesZero-duty access on more than 80% of India–ASEAN trade suggests unused preferences are a cost lever.
• Count the transshipment legShallow ports push cargo through Singapore, adding a costly leg that adds time and cost to the lane.

Strategic Playbook

1. 1
   Model origin scenarios

   Re-run landed cost for each Vietnam-made SKU at its declared duty and at a 40% penalty case, bracketed by the 46% and 20% rates.

2. 2
   Qualify an Indian second source

   Shortlist one Indian supplier for the Vietnam lines and confirm preference eligibility before any Section 301 outcome is known.

Claims ledger: 12 facts and where each comes from

• Vietnam surpassed China as the leading U.S. supplier of laptops and game consoles for the first time last year, per a Bloomberg analysis of shipment-level customs data.²
• The core production of those electronics is still happening in China.²
• Vietnamese factories that assemble Chinese-made components added less than 8% of export value in some cases.²
• U.S. imports from a group including Vietnam, India and Mexico rose by a cumulative $49 billion, while China's shipments to the U.S. fell by $51 billion last year.²
• In the same executive order, a 40 per cent transshipment penalty applies to products composed primarily of foreign materials that receive only minor assembly elsewhere.³
• Vietnam's steep 46 per cent duty, imposed in April 2025, was later slashed to 20 per cent, but with a catch.³
• Section 301 probes into Vietnam's IP protection, manufacturing capacity and labour practices are underway.³
• India and Vietnam set a target of boosting bilateral trade to US$25 billion by 2030, up from US$18.28 billion in 2025–26.¹
• The existing ASEAN-India free-trade agreement provides zero-duty access to more than 80 per cent of bilateral trade by value, according to Ajay Srivastava of the Global Trade Research Initiative.¹
• Srivastava said existing ASEAN–India preferences remain underused.¹
• Limited deep-water ports in Southeast Asia prevent larger cargo vessels from docking, requiring costly transshipment through hubs such as Singapore.⁴
• Industrial and logistical infrastructure in the eight emerging economies studied still lagged behind China's, though the gap was narrowing.⁵
