## Market Overview Operational bottlenecks and severe berth congestion at Kolkata Port (Syama Prasad Mookerjee Port) have emerged as a significant logistical hurdle for polymer importers and processors across Eastern India today, September 7, 2026. Container vessels carrying key polymer resins—including Polypropylene (PP), Polyvinyl Chloride (PVC), and Polyethylene (PE) grades—are facing extended waiting times at anchorages, leading to delayed customs clearances and congested container yards.
The logistical friction has severely impacted the downstream supply chain in regional processing clusters, including Kolkata, Howrah, Durgapur, and neighboring manufacturing hubs in Odisha and Bihar. Importers and local distributors report that discharge operations have slowed noticeably over the past week due to feeder vessel delays, equipment shortages, and synchronized heavy arrivals of containerized cargo.
## Demand and Supply On the supply front, the inflow of imported polymer resin containers into Eastern Indian processing hubs has decreased due to berth delays. While domestic supply from primary petrochemical refiners remains operational, regional inventory levels at port-adjacent warehouses are depleting rapidly. Converters relying on imported PVC suspension grade and LLDPE film grade materials are experiencing immediate inventory shortfalls.
Demand for raw polymer materials across Eastern India remains steady, supported by consistent requirements from flexible packaging, agricultural pipe manufacturing, and consumer durable sectors. However, processors are constrained by delayed raw material deliveries, forcing several small and medium enterprises (SMEs) to adjust their production schedules or source urgent spot supplies from regional traders at a premium.
## Price Trends The logistical bottlenecks at Kolkata Port have indirectly influenced spot market pricing across Eastern India. While primary producers have maintained stable price lists, regional spot prices for imported PP raffia, PVC suspension grade, and HDPE film grade have firmed up slightly today due to immediate spot supply constraints in Kolkata and adjacent trading centers.
Secondary transport costs have also escalated as local trucking operators levy demurrage and port-detention surcharges on container movements. Importers are attempting to pass these additional logistics expenses onto end-users, resulting in elevated landed raw material costs for plastic processors across the Eastern corridor.
## Regional Focus The Eastern region, particularly industrial clusters in West Bengal such as Howrah, Dankuni, and Haldia, is bearing the immediate brunt of the port congestion. Plastic converters in these hubs rely heavily on imported resin arrivals via Kolkata and Haldia ports for specialized film, packaging, and pipe manufacturing applications.
Neighboring processing hubs in Cuttack, Bhubaneswar, and Patna are also experiencing ripple effects, as delayed container dispatches from Kolkata Port slow down overland trucking deliveries. Regional trade associations are actively liaising with port authorities and logistics providers to request prioritized evacuation of raw material container units.
## Outlook In the short term, logistics service providers expect berth congestion at Kolkata Port to persist over the coming days until vessel scheduling normalizes and container evacuation rates improve. Port authorities are reportedly working on clearing the vessel backlog by optimizing crane deployment and expediting container yard transfers.
Polymers Bazar advises converters and traders in Eastern India to plan their procurement cycles with additional lead time and consider alternative logistics routes or domestic supply channels where feasible. Market participants anticipate that supply chain fluidity across the Eastern corridor will gradually stabilize towards mid-September 2026 as port operations recover.
