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.
Resin Manufacturer Liability
Meaning
Corporate obligation limits the accountability of a polymer producer for defects or failures in their material. Producers provide a limited warranty that the resin meets the published technical specifications at the time of delivery. The liability is restricted to the raw material and does not extend to the final application or finished part performance.
Warranty Limit
Most producers provide a limited warranty that the resin meets the published technical specifications at the time of delivery. Under resin manufacturer liability, the producer is usually not responsible for failures caused by improper moulding or incorrect material selection. These contracts often limit the total damages to the purchase price of the resin batch.
Risk Transfer
Moulders and brand owners must conduct their own testing to ensure the material is suitable for the final application. Although resin manufacturer liability covers batch-to-batch consistency, it does not guarantee that a part will perform in a specific environment. Clear terms and conditions in the sales contract define where the producer’s responsibility ends.
Liability Limit
Disputes over material quality are often settled through replacement of the resin or a credit on future orders. Producers rely on detailed quality records to prove the material met all specifications before leaving the factory.
