南非采购需求：门到门配送、海运、空运、铁路运输、海运门到门、国际空运

I'm looking to get a quote for shipping 1 cubic meter of AI plushies that contain lithium-ion batteries from Shenzhen to Johannesburg, specifically to 26 Turtle Dove, Lenasia Extension 1. Please provide the sea freight cost, including any additional fees that may apply for handling lithium-ion battery shipments. Additionally, if you could share the estimated transit time and any necessary documentation or regulations I should be aware of when importing these items into South Africa, it would be greatly appreciated. Thank you!
