I'm looking for roof and wall sandwich panels and would like to know if you can provide these products. Additionally, please share the HS (Harmonized System) codes that you use for importing these items into Jakarta, Indonesia. This info is crucial for us to ensure smooth customs clearance and compliance with import regulations. Could you also provide details on the specifications, available options, and lead times for these sandwich panels? We want to understand all available choices before making a commitment. Your prompt response would be appreciated as we aim to move forward quickly with our project. Looking forward to hearing from you soon!
