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.
- Express Delivery: Services like DHL, FedEx, and UPS are ideal for samples or urgent shipments.
Domestic Shipping:
- Use local logistics providers for truck or rail transport, or opt for express couriers.
- Choose cost-effective, time-efficient shipping services based on the delivery location.

2. Decide on Shipping Costs

Set flexible payment terms for shipping costs based on customer type and agreement:

Suppliers are responsible for delivering goods to the specified port, while customers handle the freight from the port to their destination. Suitable for customers with established logistics networks.
CIF (Cost, Insurance, and Freight):
Suppliers cover freight and insurance costs to the destination port. Ideal for smaller clients who prefer reduced shipping complexity.
EXW (Ex Works):
Customers handle all shipping costs and risks starting from the supplier’s factory. This option works well for clients with their own freight forwarders.
