Meaning
Legal possession of a physical asset transfers from the owner to a temporary custodian without the movement of property ownership. True bailment creates a specific duty of care where the custodian assumes responsibility for the safe return or disposal of the goods according to agreed terms. Parties must clearly define the scope of control and the duration of custody to avoid claims of abandoned property or conversion.
Processing Responsibility
Polymer pellets undergo this arrangement when a resin supplier provides material to a moulder on a consignment basis before final invoicing. The moulder holds the resin in their facility while the supplier retains legal title to the plastic until the machine operator draws the material for production. High moisture sensitivity in engineering plastics like nylon necessitates strict climate control during this period to prevent degradation.
Failure to maintain these conditions results in a loss of structural performance in finished parts.
Specification Distinction
Part specifications define the geometric tolerances and functional requirements for the final moulded component. True bailment governs the movement and storage of the material stocks that exist before those components receive their shape. Virgin resin maintains consistent molecular weight distribution according to the manufacturer datasheet.
Regrind or recycled material batches lack this uniformity and complicate the custodian duty because their processing properties shift with each thermal cycle.
Custody Liability
Machine downtime or power outages within the moulding plant expose the custodian to costs associated with damaged or degraded material assets. Moulders accept the risk of spoilage if they cannot prove the environmental conditions remained within the storage limits required by the resin datasheet. Proper documentation of humidity levels and warehouse temperature confirms that the custodian met the duty of care for the entrusted plastic.
Market practice dictates that the legal status of the goods remains separate from the physical output of the moulding process.
