When suppliers list their dried fruit products as Factory Tested on Alibaba.com, they're indicating that each production batch undergoes quality verification before shipment. But what does this actually mean in practice? The term encompasses several layers of testing, documentation, and certification that vary significantly between suppliers and product categories.
For dried fruit specifically, factory testing typically includes moisture content analysis (critical for shelf life), microbiological screening (detecting mold, bacteria, and pathogens), nutritional parameter verification (confirming label claims), and contaminant testing (pesticides, heavy metals, allergens). Each test requires specialized equipment and accredited laboratory procedures.
The testing infrastructure varies widely. Some suppliers operate in-house laboratories with basic testing capabilities, while others partner with third-party accredited labs (ISO/IEC 17025 certified) for comprehensive analysis. The latter provides more credible documentation but comes at higher cost and longer turnaround time.
