Ensure the supplier provides an accurate Commercial Invoice, Packing List, and Certificate of Origin. For apparel, the HS Code (typically Chapter 62 for non-knitted shirts) must be correct to avoid customs delays or incorrect duty applications. For urgent seasonal party trends, use Air Freight for small batches, but for bulk inventory, Sea Freight (LCL or FCL) is significantly more economical. Always confirm if your country has Free Trade Agreements (FTA) with the sourcing origin to reduce import tariffs.
