韩国采购需求：球囊管、双层球囊管、三层管、多层管、内腔管、管材挤压

I'm looking to source micro tubes for our upcoming project. We need to ensure they meet specific quality standards and can handle varying temperature conditions. Please provide me with info on your available options, including size variations, materials, and any certifications. Additionally, could you let me know your lead times for production and shipping? Pricing details would also be helpful, especially for bulk orders. Looking forward to your prompt response so we can move forward quickly. Thanks in advance!
