WHAT ABOUT YOUR QUALITY ASSURANCE SYSTEM?
The internal QC department of China Liuyang Fireworks is in charge of checking the purchase of raw material, chemical composition to manufacturing process. We have the chemical composition information, drawings, and samples for most of our products. We never buy from outside if we can make the product. We never give up any chance of learning from outside, especially the foreign experienced dealer and pioneer of fireworks industry.
