Global Polymer Trade Routes: Who Ships to Whom, and How

Polymer trade is shaped less by who can produce most cheaply and more by who can deliver most cheaply to where the conversion is happening. The conversion industry sits in five clusters: India and Southeast Asia, China, Mexico and Brazil, Western Europe, and the US Northeast. The polymer goes where the converters are. The route between them is what determines the actual delivered price.

GCC → South Asia#

This is the single densest polymer-trade lane in the world. Jubail Commercial Port and King Fahd Industrial Port in Saudi Arabia, Ruwais in the UAE, and Mesaieed and Ras Laffan in Qatar ship into Mumbai's Jawaharlal Nehru Port Trust (JNPT / Nhava Sheva), Mundra, Hazira, Pipavav, and Karachi. Transit is 7–12 days. Volumes move on Maersk, MSC, CMA CGM, Hapag-Lloyd, ONE, and HMM services with weekly frequency.

Most of this is FOB GCC port or CFR Indian port. Letters of credit on this lane are typically 90 days at sight or 90 days from BL date — see payment terms in polymer trade for what those mean operationally. The buyer is usually a converter or trader; the conversion goes into film, woven sacks, pipe, or moulded goods for the Indian domestic market.

GCC → China and Southeast Asia#

GCC origins ship into Ningbo-Zhoushan, Shanghai (Yangshan), Shenzhen (Yantian), Qingdao, and Tianjin Xingang for Chinese converters. The same producers ship into Map Ta Phut (Thailand), Tanjung Pelepas (Malaysia), Singapore (PSA), and Cai Mep (Vietnam) for Southeast Asia. Transit is 14–20 days to North China, 12–16 days to South China, 10–18 days to Southeast Asia.

This is the lane where benchmark CFR China prices are made. ICIS and Argus publish daily LLDPE, HDPE, and PP CFR China benchmarks that price almost every other Asian transaction by reference. CFR China weakness in any month tells the global desk that producer margins are compressing; CFR China strength tells everyone the opposite.

US Gulf Coast → Europe and Latin America#

The post-2018 US Gulf Coast PE capacity expansion — Dow Freeport, ExxonMobil Baytown, Chevron Phillips Cedar Bayou, LyondellBasell Channelview, Formosa Point Comfort, Shintech Plaquemine, LACC — produced a structural export surplus. The two main outlets are Houston → Antwerp / Rotterdam (18–22 days direct, 22–26 days with calls) and Houston → Manzanillo / Veracruz / Vera Cruz / Buenos Aires / Santos (8–18 days depending on Latin America destination).

European arrivals from Houston are mostly LLDPE and HDPE film grades that compete directly with Antwerp- and Rotterdam-loaded INEOS, Borealis, and ExxonMobil European production. The arbitrage works when CFR NWE pricing is at least 40–60 USD/MT above delivered USGC parity — a window that has been open most months since 2022 due to weak European cracker margins.

Northeast Asia → Latin America and Africa#

Korean and Chinese producers ship LLDPE and HDPE into Latin American and African converters as a discretionary export tier when local Chinese demand is weak. Routes include Ulsan / Yeosu → Manzanillo (~22 days), Ningbo → Santos (38–42 days), and Shanghai → Durban / Lagos / Dar es Salaam (28–36 days). These are the lanes that absorb Chinese petrochemical surplus when the domestic market softens.

Africa specifically is a growing buyer cluster. Lagos (Apapa), Tema (Ghana), Mombasa, Dar es Salaam, Durban, and Casablanca all import polymer into local conversion industries. Volumes per shipment are smaller — typically 1–3 FCL per buyer — but cumulative growth is meaningful.

Europe → Africa and the Mediterranean#

Antwerp, Rotterdam, Hamburg, Le Havre, and Tarragona ship Mediterranean and African destinations on shorter cycles. Antwerp → Casablanca is 5–7 days; Antwerp → Lagos is 12–16 days; Tarragona → Algiers is 2 days. These short-haul lanes are typically smaller volumes per booking but with frequent service.

Chokepoints and current routing realities#

Three chokepoints dominate operational risk: the Suez Canal / Bab-el-Mandeb (Red Sea), the Strait of Malacca, and the Panama Canal. Suez and the Red Sea have been the active disruption since late 2023. Container lines have routed most Asia–Europe and Mideast–Europe polymer flow round the Cape of Good Hope, adding 10–14 days transit and 400–800 USD/FEU in fuel and capital cost. Most desks now price Cape routing as the default and treat any Suez return as upside.

Panama Canal drought events in 2023–2024 caused a temporary preference for the Suez routing on US Gulf Coast → Asia traffic; this has since normalised, but operational lead times on USGC → Asia remain volatile.

Container availability as a leading indicator#

Polymer is one of the heaviest dry-cargo container loads (a 40-foot container of resin can run 24–26 tonnes net). That makes polymer-export bookings sensitive to container supply, weight restrictions, and intermodal terminal congestion. When equipment shortages spike at Pearl River Delta or US Gulf terminals, FOB prices effectively rise even when published producer offers do not move — the buyer simply cannot lift the cargo.

A working desk treats container index movements (Drewry, Freightos Baltic Index) as a leading indicator of effective polymer pricing. A 30% jump in CHTW → EU container rates moves CFR NWE polymer 40–60 USD/MT in the same week, all else equal.

Implications for sourcing#

Three working rules. First, the cheapest FOB origin is rarely the cheapest CFR destination once route, transit, and current freight conditions are loaded in. Second, weekly service frequency is worth a real premium — a route with three weekly sailings is materially less risky than a route with one. Third, the L/C tenor and the actual lead time interact: a 90-day L/C from BL date on a 35-day Cape-routed sailing leaves the buyer 55 days on the receiving end, which is the working capital that actually matters.
