哥伦比亚采购需求：张紧轮、皮带轮、后减震器、优质减震器、滤清器、轮毂密封圈

I'm looking for high-quality hoses suitable for both cars and trucks. It would be great to have detailed information on the specifications, materials used, and any certifications your products may have. Additionally, pricing and minimum order quantities would be appreciated. Could you also provide info on lead times and shipping options? If you have a catalog or product list, that would be helpful too. I'm eager to explore potential collaboration, so looking forward to your prompt response!
