How to Verify Production Lead Times: Realistic vs Overpromised

Video factory tours have become standard since 2020 but can be misleading. Ask the supplier to walk through specific areas: raw material storage, production lines, quality control stations, and finished goods warehouse. Request to see specific machines relevant to your product. Watch for inconsistencies — clean showroom but chaotic workshop, or different facilities than shown in previous videos. A live video call is harder to fake than a recorded tour.

Phone calls reveal more than emails. A legitimate factory manager can answer technical questions about production processes without checking. A trading company representative will often need to 'confirm with the factory' for basic technical details. Schedule a voice or video call early in your evaluation. Listen to how questions are answered — hesitation, vagueness, and over-promising are all warning signs.

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.
