Contractual Allocation
Contractual terms governing financial and operational responsibility define the allocation of risk for customer-furnished parts held at an electronic manufacturing services facility. Under standard commercial agreements, consigned material liability establishes which party absorbs losses stemming from transit damage, warehousing attrition, moisture degradation, or assembly yield fallout. The customer retains ownership of the raw inventory while transferring physical custody to the assembler.
Liability transfers back to the consignor when unworked parts fail incoming verification or exhibit latent manufacturing defects. Production contracts typically define specific scrap allowance thresholds, beyond which the contract manufacturer pays replacement costs for lost or damaged parts.
Custody Attribution
Physical verification upon delivery establishes the baseline for all subsequent inventory claims. Receiving personnel log the physical condition of packaging, desiccants, humidity indicator cards, and seal integrity before moving materials to controlled stockrooms. In this phase, consigned material liability shifts according to documented receiving tallies and moisture barrier bag conditions.
If non-conforming quantities, bent leads, or oxidized terminations enter the stockroom without an immediate discrepancy report, the assembler assumes legal custody and subsequent financial responsibility for resulting production delays. Unused consigned reels return to the customer after production runs, with remaining balances audited against pick-and-place feeder attrition logs.
Financial Settlement
Reconciliation protocols govern the final accounting for damaged components, excess shrinkage, and production scrap. Standard agreements calculate scrap liability against mutually agreed baseline percentages, which generally span from one to three percent for standard surface-mount passive components and zero percent for high-cost active silicon. When manufacturing losses exceed these contractual thresholds, the contract manufacturer reimburses the component purchase price or offsets the loss against final assembly billing.
Disputed claims trigger root cause investigations to isolate feeder mispicks, solder profile mismatches, or board design anomalies from vendor packaging flaws. Direct component replacement or credit adjustments conclude the liability settlement between contracting parties.
