The China-Plus-One sourcing strategy — the practice of diversifying manufacturing outside China while maintaining some Chinese production — has been the dominant supply chain narrative since the first Section 301 tariffs in 2018. Seven years later, the strategy has matured but grown more complicated. The Liberation Day IEEPA framework added a 10% baseline tariff on all origins, Vietnam’s scheduled 46% reciprocal rate raised questions about Southeast Asian diversification, and Mexico’s USMCA advantages came with intensified transshipment enforcement. For U.S. importers evaluating alternatives, the analysis requires a complete total cost of ownership model, not a simple tariff rate comparison.
Why China-Plus-One Remains Relevant in 2026
The effective tariff rate on most manufactured goods from China in 2026 combines MFN rates, Section 301 rates (7.5% to 25%+), and IEEPA Liberation Day (145%), producing combined effective tariffs that frequently exceed 150%. At those rates, Chinese-sourced goods are economically uncompetitive in most product categories for the U.S. market unless there is no viable alternative origin. The Section 301 tariffs on China alone eliminated the landed cost advantage for most mid-value manufactured goods; the addition of the IEEPA layer rendered the arithmetic untenable for a much broader range of categories including consumer electronics, furniture, apparel, and industrial components.
The “Plus-One” in China-Plus-One does not mean complete exit from China — it means adding a non-Chinese manufacturing base to reduce tariff exposure on U.S.-bound goods while maintaining Chinese production for other markets or for products where no viable alternative exists (often advanced components or highly specialized manufactured goods).
Evaluating Vietnam
Vietnam was the primary beneficiary of the initial China-Plus-One wave beginning in 2018-2019. Major electronics, apparel, and footwear manufacturers established significant Vietnamese production capacity during this period.
Current Tariff Exposure
Vietnam was assigned the highest Liberation Day Annex II rate of any major exporter: 46%, paused at 10% during negotiations. Even at 10% (plus MFN), this represents a meaningful increase from pre-2025 tariff levels. Ongoing bilateral negotiations may reduce or lock in the Vietnamese rate, but the scheduled 46% creates uncertainty for long-term capital commitments.
Active AD/CVD orders cover Vietnamese solar panels, steel wire rod, catfish, and shrimp. For importers in these categories, the AD/CVD exposure on Vietnamese goods adds to the tariff burden and in some cases eliminates the Chinese tariff differential. Use the Captain tariff tracker to verify Vietnamese AD/CVD coverage for any specific HTS subheading.
Rules of Origin Considerations
Vietnam has no FTA with the United States, meaning Vietnamese goods receive MFN treatment at the base rate plus any applicable remedial tariffs. There is no preferential tariff layer that reduces the MFN base for Vietnamese-origin goods. For goods incorporating Chinese-origin components, transshipment rules apply: goods must undergo substantial transformation in Vietnam to qualify as Vietnamese origin. Simple assembly operations that do not meaningfully change the character of the goods do not confer Vietnamese origin; such goods may be assessed Chinese tariffs by CBP.
Landed Cost Assessment
Vietnam generally offers lower factory wages than China for labor-intensive products, partially offsetting the tariff differential. Logistics costs from Vietnam to U.S. ports are comparable to China for East Coast destinations via Suez routing and marginally higher for West Coast destinations. The supply chain infrastructure (ports, component suppliers, skilled workforce) is well-developed in Ho Chi Minh City and Hanoi corridors for most categories that have already diversified there.
Evaluating India
India has positioned itself as a major China-Plus-One destination, particularly in electronics assembly, pharmaceuticals, textiles, and gems and jewelry.
Current Tariff Exposure
India was assigned a 26% Liberation Day Annex II rate, paused at 10%. A preliminary bilateral deal framework announced in early 2026 may reduce this rate in exchange for Indian market access on U.S. agricultural and pharmaceutical products. If a deal is formalized, India could achieve a preferential tariff relationship with the U.S. for the first time — a significant competitive advantage over Vietnam and other Southeast Asian alternatives. India has no FTA with the United States under existing law. For current rates see current U.S. tariff rates by country.
Advantages for Specific Categories
- Pharmaceuticals and APIs: India is the world’s largest generic pharmaceutical exporter and a major active pharmaceutical ingredient (API) supplier. The U.S. has strategic interest in Indian pharmaceutical supply chain access, making this category particularly favorable for bilateral deal protections.
- Textiles and apparel: India’s textile industry is among the world’s largest. Labor costs are competitive, and the supply chain for cotton and synthetic textiles is deep.
- Electronics assembly: Government incentive programs (PLI schemes) have attracted major electronics manufacturers including Apple suppliers to India. Quality and volume are ramping rapidly for mid-range consumer electronics.
Considerations
India’s infrastructure gaps (port congestion, power reliability, road logistics) outside major industrial corridors remain real cost factors. Lead times can be longer than China or Vietnam for certain product categories. The legal and regulatory environment for foreign investment requires more setup time than Vietnam or Mexico.
Evaluating Mexico (Nearshoring)
Mexico benefits from USMCA and geographic proximity to the U.S. market, making it the primary nearshoring destination for supply chains serving U.S. customers that require shorter lead times or just-in-time delivery.
USMCA Advantages
Goods that meet USMCA rules of origin qualify for zero or reduced MFN rates on entry to the United States. This preferential treatment is unavailable to any Asian alternative. For products with zero USMCA tariff rates, the comparison with Vietnamese or Indian manufacturing is largely a logistics and factory cost comparison, not a tariff comparison.
Section 232 and Transshipment Risks
Mexico is subject to Section 232 TRQs for steel and aluminum. More significantly, CBP has intensified enforcement of transshipment cases where Chinese-origin goods are imported into Mexico and re-exported to the U.S. without undergoing substantial transformation. Goods found to originate in China (based on production activity, not point of export) face the full Chinese tariff stack regardless of Mexican origin documentation. Importers sourcing from Mexican facilities that use significant Chinese-origin inputs must conduct rigorous origin analysis.
Landed Cost Assessment
Mexico’s advantages are proximity (2-3 day truck transit to most U.S. markets versus 20-30 days ocean from Asia), USMCA zero tariff (for qualifying goods), and a large, experienced manufacturing workforce in automotive, electronics, and consumer goods sectors. Factory labor costs are higher than Vietnam or India but significantly lower than U.S. manufacturing for most categories. The combination of zero tariff and proximity makes Mexico compelling for products with high tariff exposure and short-cycle inventory requirements.

A complete China-Plus-One evaluation compares total landed cost, not just the tariff rate differential. The key variables are:
- Factory price difference: the cost premium or discount at the alternative origin versus China
- Tariff differential: current effective rate at alternative origin versus China IEEPA/Section 301 stack
- Logistics cost difference: freight, transit time, inventory carrying cost, and service reliability
- Quality and volume ramp: time and cost to qualify the alternative supplier and achieve target quality and output volume
- Rules of origin compliance cost: investment in local content to meet FTA thresholds (for Mexico under USMCA)
- Tariff rate trajectory: expected rate at the alternative origin under ongoing negotiations versus China rate expectation
Our trade advisory services team builds multi-scenario total landed cost models covering these variables for specific product categories. The tariff consulting component covers the HTS classification, rules of origin analysis, and tariff rate scenario modeling for each candidate country.
Frequently Asked Questions
What is the China-Plus-One strategy?
China-Plus-One is a supply chain diversification approach in which importers maintain some Chinese manufacturing capacity while adding at least one alternative manufacturing base outside China to reduce tariff exposure on U.S.-bound goods. The strategy became prominent after the 2018 Section 301 tariffs and has intensified following the 2025 Liberation Day IEEPA framework that raised effective Chinese tariffs above 150% for many product categories.
What is the current tariff rate on Vietnamese imports?
Vietnam was assigned a 46% Liberation Day Annex II reciprocal rate, paused at 10% during bilateral negotiations. MFN base rates apply at the product level on top of the 10% baseline. Active AD/CVD orders cover specific Vietnamese goods including solar panels, steel, and seafood. Check the Captain tariff tracker for current rates on specific HTS codes.
Does USMCA eliminate tariffs on Mexican goods?
USMCA eliminates MFN duties on qualifying originating goods from Mexico. Section 232 TRQs continue to apply to steel and aluminum. Liberation Day IEEPA rates apply to non-USMCA-qualifying goods. Chinese-origin goods transshipped through Mexico without substantial transformation are subject to the full Chinese tariff stack regardless of point of export.
Is India a viable China-Plus-One alternative in 2026?
India is a viable alternative for specific categories including pharmaceuticals, textiles, and consumer electronics assembly. Its Liberation Day rate (26%, paused at 10%) and potential bilateral deal trajectory make it attractively positioned for rate stability. Infrastructure gaps and longer ramp times are real considerations for industrial and high-precision categories.
What is transshipment in the context of China-Plus-One?
Transshipment refers to routing Chinese-origin goods through a third country (Vietnam, Mexico, etc.) without meaningful manufacturing transformation, to claim the third country’s more favorable tariff rate on U.S. entry. CBP applies the substantial transformation test to determine true origin. Goods that do not undergo substantial transformation in the transit country retain Chinese origin and are subject to the full Chinese tariff stack.
How do I evaluate total landed cost for alternative sourcing locations?
Total landed cost analysis compares factory price, tariff differential, freight and logistics cost, inventory carrying cost, quality ramp investment, and tariff rate trajectory for each candidate origin versus China. A tariff consulting engagement provides the tariff component; logistics and factory cost inputs come from your supply chain and procurement teams.
