A Declaration of Conformity Covering Only the Base Polymer
Base polymer declarations certify monomer purity at the reactor gate but omit all converter additives, breakdown products, and finished article migration limits.
Port Demurrage Exposure
Meaning
Financial liability arises when loaded shipping containers remain at a port terminal beyond the agreed free time allowed by the carrier. In the context of resin importing, port demurrage exposure represents an elevated financial risk when customs clearance is delayed or transport is disrupted. It involves daily fees charged by the shipping line for the continued use of their container and port space.
Moulders experience increased feedstock costs when their resin shipments are held up at the port. This exposure is limited to the terminal area and does not cover inland transit delays.
Cost Driver
Delays in document release, missing certificates of analysis, or extended customs audits are the primary causes of these fees. Once the free time expires, the daily charges escalate quickly. For a large shipment of multiple containers, these costs can accumulate to thousands of dollars in a few days.
This directly impacts the profitability of the imported resin.
Processing Consequence
When containers are stuck at the port, the molding plant may run out of resin, leading to production stoppages. This can result in missed delivery deadlines and penalties from the molder’s customers. To avoid this, molders may have to purchase expensive spot-market resin locally.
It disrupts both production schedules and budgets.
Prevention Strategy
Importers reduce risk by ensuring all documents are complete before the ship arrives. They also negotiate extended free time with the shipping line. This minimizes port fees.
