Core Conclusion: Following the implementation of this new policy, normal exports of Chinese polycarbonate (PC) panels to Mexico are virtually impossible. Direct exports and re-export trade are no longer viable. The only solution for enterprises is overseas manufacturing.
1. Final Ruling Confirmed: Universal High Tariffs on All Chinese Enterprises
On July 8, 2026, Mexico officially released its final anti-dumping ruling on Chinese polycarbonate sheet:
✅ Unified tariff for all Chinese manufacturers and exporters: $4.2301 per kilogram
✅ Effective date: Permanent enforcement starting from July 9, 2026
✅ Covering all mainstream polycarbonate sheet tariff codes withno exemptions and no differentiated rates.
Compared with the preliminary temporary tariff rate, the final rate has been further increased, drastically raising export costs for Chinese suppliers.
2. All Conventional Export Routes Blocked, Leaving No Domestic Export Options
1. Direct Exports: Completely Uncompetitive
The additional tariff exceeds $4,200 per ton. Combined with logistics and raw material costs, Chinese polycarbonate sheet have lost all price advantages against Mexican local products and goods from other countries. Any direct export order will result in definite losses.
2. Re-export Trade: Unfeasible Due to Product Characteristics
Many companies attempted to avoid tariffs via third-country re-export, yet this method is completely impractical for polycarbonate sheet.
polycarbonate sheet are thin, fragile, and scratch-prone, requiring extremely strict handling and transportation conditions. Multiple transshipments inevitably cause damage and product loss. Coupled with additional warehousing and logistics expenses, re-export costs far exceed the anti-dumping duties themselves, leaving zero profit margin for operation.
3. Only Two Viable Solutions: Overseas Factory Establishment
With both direct and re-export routes fully blocked, building overseas production bases is the only way to sustain market access in Mexico.
Option 1: Local Production in Mexico
Advantages: Zero anti-dumping duties for locally manufactured products, proximity to core Latin American markets, faster delivery, and stable customer relationships. Ideal for large-scale enterprises with long-term Mexican market layouts, stable client resources, and sufficient capital strength.
Option 2: Factory Construction in Southeast Asia (Vietnam / Thailand / Malaysia)
Advantages: Lower production costs and lower entry thresholds. Production bases in Southeast Asia can bypass Mexico’s anti-dumping barriers against China, cover ASEAN, European and American markets, and diversify operational risks. This option is more suitable for medium and small manufacturers.
4. Immediate Actions for Enterprises
Short-term Risk Control
1. Suspend all new quotation offers for direct exports to Mexico;
2. Review existing orders and in-transit goods, and negotiate with clients on tariff sharing, price adjustment, order postponement or volume reduction.
Long-term Strategic Layout
1. Conduct in-depth research on policies, costs and industrial supporting facilities for factory construction in Mexico and Southeast Asia;
2. Explore emerging markets such as the Middle East and Europe to reduce reliance on the single Mexican market.
Industry Summary
This is not a short-term trade fluctuation, but a structural blockade on China’s direct export channels. For polycarbonate sheet exporters, the era of relying solely on domestic production to supply Mexico has ended. Overseas capacity layout has become a mandatory survival strategy.
