Cross-border vehicle importers lack clear customs regulations for transporting goods through expedited US-Mexico border lanes

People frequently importing goods or vehicles from Mexico to the US via SENTRI (Secure Electronic Network for Travelers Rapid Inspection) lanes don't know the cargo capacity limits, creating risk of confiscation, fines, or lane denial. Current solutions (CBP website, phone lines) provide vague or inconsistent answers, forcing importers to guess or make expensive mistakes. This uncertainty directly impacts small business owners, resellers, and frequent cross-border traders who rely on predictable import processes.
