Shipping & Delivery

1. Determine Shipping Methods

Select the appropriate shipping method based on customer requirements and order volume:

International Shipping:
- Sea Freight: Best for large orders, offering lower costs but longer transit times.
- Air Freight: Suitable for small, time-sensitive orders or high-value products, though more expensive.

Domestic Shipping:
- Use local logistics providers for truck or rail transport, or opt for express couriers.
