US Plans 12.5% Section 301 Tariffs on China: Impact on PE, PP & PVC Exports

The United States is moving closer to imposing 12.5% Section 301 tariffs on imports from China and several other economies, with public hearings taking place from July 7-9 before a final decision is made. If approved, the new tariff structure is expected to replace the current temporary 10% tariff after July 24.

Under the proposal, Polyethylene (PE), Polypropylene (PP), and Polyvinyl Chloride (PVC) are not included in the exemption list, meaning these products will be subject to the additional tariff.

In the weeks leading up to the July 24 deadline, Chinese exporters have witnessed a sharp rise in orders as overseas buyers rush to import material before the higher duties come into effect. However, market participants believe this is only a temporary front-loading of demand rather than genuine growth in consumption. Once the tariffs are implemented, exports to the US are expected to slow significantly.

Among the three major polymers, PE is expected to face the biggest impact because it is China's largest plastic export to the US. Higher import costs are likely to make Chinese PE less competitive against material from the Middle East, Southeast Asia, and the Americas, leading US buyers to shift sourcing to alternative suppliers. This could push more unsold PE back into the Chinese domestic market, increasing inventories and putting additional pressure on prices.

The PVC sector is also expected to come under pressure. Besides PVC resin, the proposed tariffs will also apply to downstream products such as flooring, pipes, films, and other plastic goods. As exports of finished products become less competitive, demand for PVC resin within China could weaken further, adding to the already soft domestic market.

Although PP exports to the US are comparatively smaller, the new tariffs are still expected to reduce export opportunities. Producers are likely to redirect more cargoes to Southeast Asia and other overseas markets, increasing competition and narrowing export margins. This could also weigh on domestic PP prices over time.

Market participants expect the export rush to continue only until the tariff deadline. After July 24, US-bound shipments are projected to fall sharply, with PE expected to record the largest decline, followed by PVC and PP. The additional supply remaining in China may lead to higher inventories at ports and factories, keeping pressure on domestic prices during the second half of the year.

While Chinese suppliers are expected to expand sales to Southeast Asia and other international markets, analysts believe these regions will not be able to fully replace lost US demand. As a result, China's plastic industry is likely to face continued oversupply, weaker export opportunities, and softer prices for PE, PP, and PVC in the coming months.
