GST rates on textiles and garments have been revised several times, and can depend on the product type and price. Check the current rate for your product with your accountant or the trader before you price your goods.
For export orders, goods shipped out of India can be zero-rated for GST when the exporter follows the correct procedure, usually under a Letter of Undertaking (LUT). See importing from Surat.
