BOM Screening (TSCA PBT)
Definition
Bill of Materials (BOM) screening for TSCA PBT involves systematically reviewing all materials, components, and substances in a product BOM against the five restricted PBT chemicals and their concentration thresholds. This is the primary compliance verification method for manufacturers and importers.
Source
No official TSCA procedure; operationally derived from 40 CFR Part 751 compliance requirements.
Practical Explanation (Compliance Context)
BOM screening should be integrated into design, procurement, and incoming quality processes. Screen for: DecaBDE in flame-retardant plastics/textiles; PIP (3:1) in flame retardants, lubricants, and plastics; 2,4,6-TTBP in fuel/lubricant additives; PCTP in rubber products; HCBD in chemical intermediates. Use supplier declarations and analytical testing to validate.

Example
An automotive OEM screens its full vehicle BOM (12,000 part numbers) against the five PBT chemicals using Regilient. The screening flags 340 parts with potential PIP (3:1) content in flame-retardant plastics. The OEM initiates targeted supplier declarations for these parts.
