Behind every sainsburys firework sparklers factory is a rigorous testing and inspection process that ensures product safety. Before packaging, each batch of sparklers goes through a burn test to check spark quality, duration, and ignition reliability. The factory team may also test resistance to moisture and physical impact. These quality control steps are essential for complying with export standards and building long-term trust with overseas buyers. Some factories even allow clients to request third-party inspections prior to shipment.
