美国采购需求：理发盒、电池盒、便携包、无人机盒、耳塞盒、耳机盒

I'm looking for a reliable supplier for EVA tool cases designed for heavy parts, with OEM-level requirements. We anticipate an annual volume of 10,000 pieces across four different variations, totaling 40,000 units over the next four years. Key specifications include stringent flammability standards for both the outside casing and EVA foam, so FR finishing is required. The development lead time is one year, including time for sample production. The materials needed are PU, EVA, and Velvet, with a custom size and black color. We also require customized logo patches on the cases. Additional specs include automotive flammability, surface abrasion resistance, and heat resistance. These cases will be used for various applications including tools, cosmetics, watches, and electronics, serving as hard storage solutions. If you're interested and can meet these requirements, please get in touch.
