How to Verify Production Lead Times: Realistic vs Overpromised

Your gut feeling after multiple interactions with a supplier is a valid data point. If communication is consistently slow, answers are evasive, or promises are repeatedly broken during the sales process, those patterns will worsen during production. A supplier's sales behavior is the most accurate predictor of their operational behavior. If something feels off during quotation and negotiation, trust that instinct and dig deeper before committing.

Customs data platforms reveal a supplier's real export history. You can see what products they've shipped, to which countries, at what volumes, and how frequently. A supplier claiming years of experience but showing only a few shipments is a red flag. Conversely, a supplier with consistent shipments to reputable buyers in your market is a strong positive signal. Use this data to prioritize which suppliers to visit.
