Brazilian polyethylene (PE) buyers are turning again to US product following the expiration of Brazil's provisional antidumping duty on US and Canadian material, while a ditributor for domestic producer Braskem has advised it is running out of product.
The domestic supply picture deteriorated after a Braskem distributor notified clients in a 5 March letter that all grades were unavailable and that there was no forecast for new arrivals from its supplier. The distributor also noted that market participants were speculating about further price increases and that several product lines had already reached zero inventory, with the situation likely to worsen in the coming days. The combination of limited domestic availability and reduced import flows from the Middle East because the US-Israel war on Iran has increased reliance on alternative supply routes, particularly from the US.
In light of the supply disruptions, the expiration of Brazil's provisional antidumping duty on US ($199.04/metric tonne) and Canadian ($238.49/t) PE has taken on heightened importance for the domestic market.
The timing is critical because the conflict in the Middle East continues to disrupt shipping routes and constrain liftings, narrowing the supply available to Brazilian buyers just as logistical pressures intensify across global corridors.
More than a tenth of the global container fleet is currently exposed to Mideast Gulf trade routes, which underscores the strategic weight of the region for world shipping, according to logistics provider Ceva, which also reported that over 140 container ships representing more than 470,000 TEU (twenty-foot container) are trapped or waiting in the Arabian Gulf, with security concerns and port disruptions slowing vessel movements.
Freight markets have reacted quickly, with China-to-UAE spot rates rising by nearly 25pc since mid-February as carriers introduce surcharges in response to the rising uncertainty. War risk insurance premiums have increased fivefold, reinforcing the operational strain felt across routes linked to the conflict, Ceva said.
Brazil antidumping duties end
The sequence of events surrounding Brazil's antidumping investigation helps explain how this backdrop has shaped market behavior.
The trade authority initiated the case in November 2024, issued a preliminary determination in August 2025 and extended the process to May 2026. A provisional duty was applied shortly after with a maximum duration of six months. In the absence of any government notice extending that measure, the tariff expired in February 2026, although the broader investigation remains active within its legal timeframe.
Though new provisional duties could be applied at any time, buyers are willing for now to take the risk on ordering product from the US, particularly given the supply tightness and higher prices from local producer Braskem.
Braskem had released its March pricing policy signalling a rollover for PE, but on 2 March it issued a revision lifting prices by $50/t. A second revision was announced on 5 March raising prices by an additional $318/t. The rapid succession of these increases, combined with the absence of domestic supply, pushed buyers to seek alternative sources at a time when regional and global logistics were already under strain.
With imports from the Middle East constrained and domestic availability curtailed, attention has shifted back to US-origin material.
US producers have also been raising prices, requesting increases of up to 10¢/lb, according to letters viewed by Argus. Despite these adjustments, US PE remains competitive for Brazilian importers because transit times are shorter, the US logistics network is unaffected by the conflict and the overall landed cost remains attractive even after a $12/t rise in freight on the Houston to Santos route.
The combined effect of these pressures has prompted converters and distributors to revisit procurement strategies. Buyers are reassessing cfr offers from US suppliers, diversifying carriers to improve booking reliability and managing the balance between domestic and imported volumes as Brazilian prices move higher.
With Braskem implementing consecutive price increases while holding less inventory and with Middle Eastern shipments facing serious operational constraints, US-origin PE has re-emerged as a practical and increasingly necessary second supply option, and its relevance is likely to grow in the near term as long as domestic replenishment remains uncertain and global shipping conditions continue to deteriorate.
