In July 2026, China's textile exports showed an intriguing divergence: growth in exports of yarn, fibers, and fabrics outpaced that of garments. Behind this data lies the surging garment exports from Vietnam and Bangladesh to the US market, while Chinese fabrics still dominate their raw material imports. On the surface, this is a natural result of industrial relocation, but in reality, it hides a tariff landmine—origin determination is not based on where sewing occurs but traces back to yarn sources.
The 'Guilt by Association' Logic of Origin Rules
Customs in the EU and US determine the origin of textiles based on the 'from yarn forward' accumulation rule. A shirt sewn in Vietnam, if its fabric and yarn come from China, is deemed 'associated with China' in the eyes of EU and US customs. This means that companies that painstakingly relocate assembly to Southeast Asia may neither enjoy tariff preferences nor face risks of back taxes, fines, or even cargo detention due to upstream raw material origins.
US customs statistics show that China's exports of knitted and non-knitted garments to the US have declined, while Vietnam and Bangladesh's imports of man-made filaments and staple fibers from China remain high. This data outlines the true shape of the 'China+1' supply chain: China exports high-value-added fabrics, while Southeast Asia handles low-value-added sewing. Once origin is traced, this division of labor becomes a 'labor for others' trap.
Industrial Cluster Response and Upstream-Downstream Transmission
Vietnam and Bangladesh's textile industries are still dominated by processing trade, with insufficient local capabilities in spinning, weaving, and dyeing, making full-chain localization difficult in the short term. This means that upstream dependence on China will not change soon. For Chinese companies, this is both an opportunity and a risk: the opportunity lies in continued growth of intermediate goods exports, while the risk is that relocation of garment production may trigger origin inspections.
For domestic fabric suppliers, order structures are subtly shifting—direct exports of fabrics to Southeast Asian factories face different compliance requirements than exports to domestic garment makers. The former requires more detailed material traceability documents, while the latter is relatively simpler. This change will force upstream companies to establish more robust origin management systems, or risk losing orders due to downstream customers being audited.
Practical Recommendations
For Buyers - When evaluating Southeast Asian suppliers, require complete raw material purchase records to confirm fabric and yarn origins, avoiding joint tariff liability due to supplier concealment. - Include compliance clauses in contracts, specifying that the responsible party bears losses from origin-related back taxes or detention, and conduct regular supply chain audits. - Prioritize suppliers with established 'from yarn to garment' traceability systems, as they can better prove compliance during origin inspections.
For Trading Companies - Before 'China+1' expansion, hire trade lawyers to conduct a special assessment of origin rules in target markets; do not assume 'sewing location equals origin.' - Organize full-chain documentation from raw material procurement, processing procedures, to export declarations, establishing digital traceability files to handle customs inspections. - Consider gradually relocating some upstream processes (such as dyeing and weaving) to Southeast Asia, or jointly build raw material bases with local factories to fundamentally reduce origin-related risks.
The direction of supply chain restructuring will not reverse, but 'China+1' is by no means a simple 'assembly move.' Under the microscope of EU/US origin rules, any compliance flaw can be magnified into real financial losses. China's textile strength lies upstream, but to translate that strength into global competitiveness, supply chain layouts must be redesigned within the framework of the rules.
