Candidate List Duty Triggers in Component Level Imports
Candidate List duties trigger when any discrete component article exceeds 0.1 percent SVHC by weight, regardless of aggregate assembly mass.
Component Level Compliance
Meaning
Regulatory verification procedures evaluate individual moulded sub-components and raw resin formulations against chemical substance restrictions prior to final assembly integration. Verification of component level compliance requires raw material suppliers and injection moulders to provide material safety datasheets and laboratory test reports for each sub-part grade. The threshold stops at assembled finished goods where finished article testing can mask non-compliant internal inserts.
Verification Scope
Standardised testing protocols isolate individual resin grades and masterbatch additives to prevent masked contamination. When evaluating component level compliance, analytical techniques such as gas chromatography mass spectrometry verify that restricted heavy metals or prohibited plasticisers remain below specified parts per million limits. Melt flow index and tensile testing confirm that resin properties match nominal datasheet specifications.
Substrate Variation
Recycled resin content introduces chemical variability into production streams. Reclaimed regrind from external sources often contains unrecorded additives, which threatens component level compliance across extended moulding runs. Virgin resin lots maintain tighter melt viscosity and chemical purity than post-consumer flakes.
Moulding parameters must adjust for shear heating changes when processing variable scrap ratios.
Batch Liability
Undocumented material substitutions trigger immediate quarantine of affected moulding lots. Failure to secure component level compliance at the sub-tier level leads to assembly scrap and severe financial penalties. Molders manage this risk by sampling incoming resin shipments prior to press loading.
