Executive Summary
In July 2026, the United States imposed new Section 301 forced labor tariffs on imports from 60 trading-partner economies, placing Vietnam within the 12.5% duty tier—the same level applied to China. At roughly the same time, the U.S. Department of Commerce confirmed the continuation of antidumping duties on Vietnamese mattresses at rates reaching into the hundreds of percent, while CBP began conducting on-site factory inspections in Vietnam targeting Chinese-owned facilities suspected of origin circumvention. A new real-time electronic manifest data-sharing arrangement between the U.S. and Vietnam further tightens enforcement against transshipment and origin fraud. Taken together, these developments suggest that the long-standing assumption that Vietnam represents a relatively low-risk alternative to China sourcing deserves genuine reconsideration. This analysis examines the layered risks now facing importers and logistics providers operating in the Vietnam supply chain, and outlines strategic adjustments worth considering in this evolving enforcement environment.

The Vietnam Shift Trap: Tariffs, AD/CVD, and Forced Labor Enforcement Reshape Sourcing Strategies

(越南转移的陷阱：为何"中国加一"策略不再是万全之策)

1 · The End of ‘China Plus One’ as a Risk-Free Strategy

The Original Premise of Diversification

Since the onset of U.S.-China trade tensions in 2018, thousands of companies sought to reduce their dependence on Chinese manufacturing. The underlying motivation was reasonably clear: avoid Section 301 tariffs, mitigate broader geopolitical risk, and build greater supply chain resilience. Vietnam emerged as the primary beneficiary of this shift, offering competitive labor costs, ASEAN trade advantages, and relative political stability. Apparel, furniture, electronics, solar panels, and automotive parts all migrated in substantial volume to Vietnamese production lines over the following years.

A Meaningful Turning Point in Late July 2026

On July 24, 2026, that underlying calculus changed in a fairly fundamental way. The Office of the U.S. Trade Representative invoked Section 301 to impose additional tariffs on imports from 60 economies—among the largest U.S. trading partners—based on a determination that these nations had failed to impose or effectively enforce prohibitions on goods made with forced labor. The investigated economies collectively account for more than 99% of U.S. imports, meaning relatively few importers of any meaningful scale remain entirely untouched.

Vietnam was placed within the 12.5% tariff tier, alongside China, Hong Kong, Russia, Thailand, and several other countries. While Vietnam had issued a decree just two days earlier prohibiting imports of goods produced with forced labor, USTR determined that this eleventh-hour measure was insufficient on its own to warrant placement in the lower 10% tariff tier.

A meaningful shift worth understanding clearly: Vietnam now faces essentially the same 12.5% Section 301 forced labor tariff as China. The tariff advantage that originally drove much of the “China plus one” sourcing strategy has been substantially narrowed, and in some cases effectively neutralized, for broad categories of goods.

2 · The Layered Tariff Risks Facing Vietnam-Sourced Goods

The 12.5% Section 301 Forced Labor Tariff

This new tariff applies to covered goods entered or withdrawn from warehouse for consumption on or after July 24, 2026. Importantly, this 12.5% duty stacks on top of existing tariffs—including any applicable standard MFN rates and applicable antidumping or countervailing duty orders. For goods that previously moved through Vietnam specifically to avoid the 25% China-specific Section 301 tariff, the new 12.5% Vietnam tariff meaningfully narrows, and in some cases largely eliminates, that prior cost advantage.

Apparel Sector Impact: Vietnam’s largest export category to the United States—apparel and textiles—now faces this 12.5% adder directly. Competing suppliers such as Bangladesh, Cambodia, Indonesia, and Malaysia face a comparatively lower 10% rate under the same broader framework. USTR has also signaled intent to establish tariff-rate quotas for certain textile and apparel products from Bangladesh, Cambodia, Indonesia, and Malaysia—based on U.S. input content—that would allow duty-free entry within defined volumes once implemented. Vietnam has not currently been included within this relief mechanism.

A Separate Intellectual Property Investigation

Vietnam is also currently the subject of a distinct Section 301 investigation, initiated on May 29, 2026, following its designation as a Priority Foreign Country in USTR’s April 2026 Special 301 Report—the first time in over a decade that any country has received this most serious of IP-related designations. The investigation examines Vietnam’s persistent failure to address online piracy, counterfeit goods, weak border enforcement, and unlicensed software use. Importers should reasonably anticipate the possibility of additional tariffs or other trade restrictions arising from this separate track, entirely independent of the forced labor tariff described above.

3 · Antidumping and Countervailing Duties: A Growing and Serious Risk

Antidumping and countervailing duties have long represented a meaningful risk consideration for Asian sourcing generally, but the rates applied to certain Vietnamese products in 2026 have reached genuinely extraordinary levels.

Mattresses: Duties Reaching Well Into the Hundreds of Percent

On July 31, 2026, the U.S. Department of Commerce published the final results of its expedited sunset review, finding that revocation of the existing antidumping order on mattresses from Vietnam would likely lead to continuation or recurrence of dumping at a weighted-average margin of up to 668.38%—among the highest rates applied to any Vietnamese product category. Comparable margins were confirmed across the other countries covered by the same review: Thailand at up to 763.28%, Serbia at 112.11%, Cambodia at 103.79%, and Malaysia at 42.92%.

While Vietnam’s confirmed rate is somewhat lower than Thailand’s in this instance, both figures are commercially prohibitive in practical terms. Any mattress importer sourcing from Vietnam should treat this as a standing, near-existential cost risk requiring active monitoring rather than a background consideration.

Other Vietnam-Specific Actions Worth Noting

Frozen fish fillets and seamless refined copper pipe from Vietnam remain subject to existing antidumping orders. Separately, administrative reviews covering gas-powered pressure washers from both China and Vietnam were discontinued in early August 2026, meaning the cash deposit rates in effect during the relevant review period have now become final—effectively eliminating any possibility of retroactive refunds and confirming the duties already assessed during that period.

Understanding the Review Discontinuation Risk

Early August 2026 marked a fairly significant procedural shift worth understanding. CBP and Commerce discontinued administrative reviews for multiple product categories involving both Vietnam and China, including crystalline silicon photovoltaic products and gas-powered pressure washers from both countries.

When an administrative review is discontinued in this manner, the entries covered by that review are generally liquidated at the cash deposit rate that applied at the time of entry. This means importers lose the opportunity to potentially benefit from a lower final rate that might otherwise have emerged through a completed review process. In practical terms, this transforms what had been a contingent liability into an immediate, fixed cost—and if the original deposit rate happened to be set relatively high, importers generally have no meaningful path toward a downward adjustment.

4 · Origin Enforcement: Transshipment and Substantial Transformation Under Closer Scrutiny

The Reciprocal Trade Framework and Its Transshipment Penalty

Separately from the new forced labor tariff, Vietnam has operated since mid-2025 under a bilateral reciprocal trade framework: a preliminary agreement announced in July 2025 and formalized in an October 2025 joint statement between the two governments. Under that framework, genuinely Vietnamese-origin goods face a 20% reciprocal tariff, while goods determined to represent transshipments from third countries—particularly China—face a considerably steeper 40% tariff, applied under HTS heading 9903.02.01, with no mitigation or remission available once a shipment is found to be transshipped. Negotiations toward a full, finalized bilateral trade agreement were continuing as of mid-2026, but the 20%/40% structure itself has already been in active effect for roughly a year and now sits alongside, and stacks with, the new 12.5% Section 301 forced labor tariff described above.

This explicit distinction signals fairly clearly that U.S. enforcement authorities increasingly view Vietnam as a potential conduit for circumventing duties on Chinese-origin goods specifically. The 40% rate appears intentionally punitive, designed to eliminate much of the economic incentive that might otherwise exist for transshipment schemes.

On-Site Factory Inspections in Vietnam

In July 2026, CBP began conducting on-site inspections of Chinese-owned factories operating within Vietnam. Inspection teams have been reviewing production records, raw material sourcing documentation, and manufacturing processes to assess whether the legal “substantial transformation” standard has genuinely been met. Under U.S. origin law, mere assembly, repackaging, or minor processing occurring in a third country does not change a good’s country of origin for tariff purposes—the goods generally remain Chinese-origin regardless of where final packaging or minor processing occurs.

The practical risk here is fairly significant. Importers claiming Vietnam origin for goods that would ultimately fail the substantial transformation test face not only retroactive duty assessments, but also potential fraud penalties under existing customs law, which can reach the full domestic value of the merchandise involved for fraudulent violations specifically.

Real-Time Manifest Data Sharing

In June 2026, the United States and Vietnam signed a memorandum of understanding establishing real-time, or near-real-time, sharing of electronic cargo manifest data between the two countries. This arrangement gives CBP meaningful visibility into shipment-level details well before goods actually depart Vietnam, supporting more advanced risk scoring for transshipment indicators, enhanced targeting of suspect shippers and consignees, and cross-referencing of declared origin against known production capacity data.

This data-sharing arrangement effectively closes much of the information gap that had previously allowed some transshipment schemes to operate with a meaningful degree of impunity.

5 · Forced Labor: Exposure Extending Well Beyond Simple Detention

A Decree That Arrived Somewhat Late in the Process

Vietnam issued a decree in late July 2026 prohibiting the import of goods produced with forced labor. While a meaningful step forward in formal terms, this decree did not ultimately alter USTR’s determination that Vietnam had failed to effectively enforce such prohibitions in practice—which is precisely why the 12.5% tariff was applied regardless.

Criminal Exposure Under the Broader Enforcement Framework

The jointly issued DOJ-DHS Resource Guide to Trade Fraud Enforcement makes reasonably clear that forced labor violations are no longer treated merely as a customs detention issue in isolation. Under existing federal peonage law, any person who knowingly benefits financially from participation in a venture engaged in forced labor—with actual knowledge or reckless disregard for that fact—has potentially committed a federal crime. This exposure extends meaningfully beyond the importer of record to downstream distributors, retailers, and logistics providers that handle goods ultimately connected to forced labor practices.

Importers sourcing from Vietnam’s textile, seafood, and agricultural sectors specifically may benefit from enhanced supply chain due diligence to help verify the absence of forced labor, including reviewing supplier labor practices directly, auditing subcontractor networks where practical, obtaining and verifying documentation of worker consent and compensation, and maintaining records sufficient to help overcome any rebuttable presumption that might otherwise apply.

6 · Considerations for Logistics Providers

For logistics companies and customs brokers serving clients with Vietnam sourcing exposure, the current enforcement landscape suggests a more proactive, consultative role may be increasingly valuable relative to a purely transactional one.

Communicating Cost Impacts to Clients

Clients generally benefit from clear, timely communication regarding several developments: the 12.5% Section 301 forced labor tariff applying to Vietnam-origin goods entered after July 24, 2026; products covered by existing antidumping and countervailing duty orders facing rate confirmations or review discontinuations that materially affect cash flow; and transshipment risk now being subject to active on-site inspection alongside a punitive 40% tariff for goods failing origin verification.

Reviewing Origin Documentation Carefully

Rather than accepting supplier-provided origin certificates entirely at face value, logistics providers and their clients may benefit from scrutinizing supply chains for genuine evidence of substantial transformation. Useful questions include where raw materials are actually sourced, what manufacturing processes genuinely occur in Vietnam versus China, and whether there is evidence suggesting largely pass-through operations such as simple assembly, repackaging, or relabeling.

Reassessing Prior Sourcing Recommendations

Organizations that previously recommended shifting sourcing to Vietnam primarily to avoid China-specific tariffs may benefit from revisiting that guidance given current conditions. Vietnam now carries essentially the same 12.5% Section 301 rate as China, alongside meaningful antidumping and countervailing duty exposure in certain product categories and heightened origin scrutiny more broadly. Presenting clients with a fuller picture of sourcing alternatives—including countries currently within the lower 10% Section 301 tier alongside potential textile and apparel tariff-rate quota relief—may support more informed sourcing decisions going forward.

Building Compliance Capacity for Low-Value Entry Processes

As detailed in CBP’s interim final rules on low-value entries, effective July 24, 2026, with full compliance required by October 22, 2026, informal mail entries valued at $2,500 or less require an Excel spreadsheet submission to CBP rather than standard ACE transmission. Logistics providers handling e-commerce or small parcel shipments originating from Vietnam should build this manual capability proactively, while also monitoring the electronic Entry Type 13 test program scheduled to begin in September 2026 as a potential longer-term alternative.

Moving Beyond Passive Compliance Postures

The DOJ-DHS Resource Guide explicitly states that willful blindness, reckless disregard, and inadequate oversight may themselves be treated as evidence supporting enforcement actions, rather than serving as a defense against them. Logistics providers generally cannot rely on claimed ignorance of their upstream partners’ activities as an effective shield. Establishing more robust internal controls—documenting client compliance status, escalating discrepancies rather than simply filing entries as instructed, and maintaining records demonstrating the reasonable care standard generally required by law—represents a meaningful risk mitigation step in this environment.

7 · Conclusion: From a Simple Shortcut to a More Deliberate Strategy

The broader Vietnam sourcing shift is far from over—but it no longer functions as the relatively straightforward tariff-avoidance strategy it once represented. The new Section 301 forced labor tariff, meaningful antidumping and countervailing duty rates in certain categories, real-time manifest data sharing, on-site factory inspections, and an expanded liability framework collectively represent a fairly substantial reset of the compliance landscape for Vietnam-sourced goods.

A More Deliberate Framework Going Forward

Rather than searching for a single “safe” country as a wholesale replacement for China, importers and logistics providers may benefit from adopting a more deliberate, portfolio-based approach to sourcing decisions. This generally involves understanding the applicable Section 301 tariff tier for each potential origin country, screening specific products for existing antidumping and countervailing duty orders and any relevant review status, ensuring substantial transformation is genuinely documented and verifiable rather than assumed, conducting meaningful forced labor due diligence across relevant supply chains, and confirming that all logistics intermediaries involved are properly licensed, bonded, and genuinely compliance-aware.

A Broader Perspective

Current federal enforcement priorities increasingly treat trade fraud as an economic and national security concern rather than a purely administrative matter. Companies that continue treating Vietnam sourcing as a simple, low-friction extension of their prior China-focused approach—without adjusting meaningfully to the layered risks described throughout this analysis—may find themselves exposed to civil penalties, potential criminal liability, and reputational harm that could have been reasonably anticipated and managed.

2026 appears to mark a meaningful inflection point for Vietnam sourcing strategies more broadly. Moving forward successfully in this environment generally requires genuine compliance rigor, meaningful supply chain transparency, and proactive risk management—rather than reliance on Vietnam’s prior reputation as a relatively frictionless sourcing alternative.

This analysis reflects U.S. trade policy and enforcement developments as of August 2026, including the Section 301 forced labor tariff action, related antidumping and countervailing duty determinations, and the DOJ-DHS Resource Guide to Trade Fraud Enforcement. Specific tariff rates, exclusion categories, and implementation details remain subject to official Federal Register notices and subsequent agency guidance. Organizations managing Vietnam-sourced imports should consult with customs brokers, trade counsel, and compliance professionals for guidance tailored to their specific products and supply chain structures.
