Request information regarding the experience of each factory in producing your particular product. You should also ask for samples of the product. Unless you will be manufacturing your own new product, the supplier should be able to provide you with samples of the product so that you can get a better idea of the quality and know ahead of time exactly what you are paying for. Cost is not the only the consideration when choosing a supplier; quality may be just as important, and the manufacturer’s experience can be a good indication of the quality of work.
