US Section 301 Tariff Review: Implications for Asian Apparel Sourcing Strategies
JINJIANG, China — The US Section 301 tariff regime on Chinese-origin imports has been in place since 2018, with various exclusions and adjustments over the years. The most recent tariff review process, completed in 2025, maintained the existing tariff structure for most apparel categories but introduced several changes that affect mid-market apparel sourcing strategies through 2026 and 2027. The current US tariff structure on Chinese-origin apparel as of mid-2026: Most apparel categories: 7.5–15 percent ad valorem Section 301 tariff Some categories (including certain cotton and synthetic fiber apparel): 25 percent Section 301 tariff A small number of strategic categories: exemptions restored under specific programs The tariff structure has been a major driver of mid-market sourcing diversification to Vietnam, Bangladesh, and other Asian countries over the past five years. The 2025 review did not reverse this trend, but it did introduce some refinements that affect specific product categories. What’s New in 2026 The 2025 review concluded with several changes that affect apparel: Restored exclusions for certain medical and protective apparel. Some categories of medical-grade and protective apparel were excluded from Section 301 tariffs, recognizing their strategic importance. Adjusted tariff levels for some synthetic fiber apparel. Certain synthetic fiber categories that were previously at 25 percent were adjusted to 15 percent, narrowing the differential with cotton apparel. Continued exclusion process for specific HTS codes. The US Trade Representative continued the exclusion process for specific HTS codes, with quarterly reviews of pending exclusions. Strengthened rules of origin enforcement. The 2025 review also strengthened enforcement of US rules of origin, particularly for garments claiming Vietnamese or Bangladeshi origin when significant production occurred in China. Implications for Mid-Market Brands For a mid-market brand running a multi-country sourcing strategy, the 2026 tariff landscape affects sourcing decisions in three ways: Continued preference for Vietnam and Bangladesh for US-bound basic apparel. The Section 301 differential on basic knits and woven bottoms remains the dominant cost driver for US-bound sourcing. Continued Chinese competitiveness for complicated outerwear. For complicated outerwear and technical knits, the Chinese supply chain advantage often offsets the Section 301 tariff, particularly for shorter-lead-time and higher-quality programs. Increased scrutiny on origin claims. The strengthened rules of origin enforcement means that brands and sourcing agents need to verify the actual country of origin for garments claiming Vietnamese or Bangladeshi origin. This is particularly important for fabrics sourced from China and cut-and-sewn in Vietnam or Bangladesh. Enforcement Specifics for Apparel The strengthened rules of origin enforcement focuses on: Substantial transformation. US Customs applies the substantial transformation test to determine country of origin. For a garment to be considered Vietnamese or Bangladeshi in origin, the cut-and-sew assembly must occur in that country, and the garment must undergo a substantial transformation in that country. Fabric origin. For US preferential trade programs like the Generalized System of Preferences (GSP), fabric origin matters. For standard Section 301 calculations, the garment’s country of origin (where the substantial transformation occurs) is what counts. Documentation requirements. Customs requires documentation of production processes, including cut-and-sew records, fabric sourcing records, and finishing records. Brands and sourcing agents should maintain these records for all production in Vietnam and Bangladesh. Practical Steps for 2026 For sourcing teams managing tariff exposure: Re-evaluate Section 301 cost impact annually. The 2025 review introduced changes; the 2026 or 2027 reviews may introduce more. Re-evaluate the cost impact on each program annually. Verify origin claims for Vietnam and Bangladesh production. Don’t assume Vietnam or Bangladesh origin is automatic. Verify the cut-and-sew location and substantial transformation. Maintain documentation. Maintain cut-and-sew records, fabric sourcing records, and finishing records for all production. The documentation is essential for customs disputes. Consider the cumulative tariff impact. For some product categories, the cumulative tariff cost (Section 301 + standard US duties + antidumping) significantly affects the landed cost. Calculate the full landed cost for each sourcing destination. Watch for additional tariff changes. The 2026 US election cycle and changing trade policy priorities may introduce additional tariff changes. Monitor US Trade Representative announcements and respond quickly to changes. The Bottom Line The US Section 301 tariff regime on Chinese-origin apparel remains in place, with the 2025 review introducing targeted refinements but not broad changes. For mid-market brands, the tariff landscape reinforces the multi-country sourcing strategy that has been building since 2018: Vietnam and Bangladesh for US-bound basic apparel, China for complicated outerwear and shorter-lead-time production. The 2026 priority is to verify origin claims and maintain documentation in the face of strengthened customs enforcement.
