Customers often prefer shipping clay bars by sea for several reasons:

1. Cost-Effectiveness: Shipping by sea is generally more cost-effective for bulky or heavy items like clay bars compared to air freight. Sea freight rates are often lower per unit of weight or volume, making it economical for larger shipments.

2. Suitability for Bulk Orders: Sea freight is ideal for shipping large quantities of clay bars or other products in bulk. It accommodates larger containers and allows for efficient handling of substantial inventory volumes.

3. Less Stringent Size and Weight Restrictions: Unlike air freight, which has strict limitations on size and weight, sea freight allows for shipping of larger and heavier packages without significant surcharges or restrictions. This makes it feasible to transport bulk quantities of clay bars in a single shipment.

4. Environmental Considerations: Sea freight is considered a more environmentally friendly option compared to air freight, as it generally produces fewer carbon emissions per unit of cargo transported over long distances.

5. Reliability and Accessibility of Ports: Major ports are well-equipped to handle sea freight shipments, offering reliable logistics infrastructure and extensive network connections to facilitate smooth transit and distribution of clay bars to various destinations worldwide.

6. Longer Shelf Life and Stability: Clay bars, being non-perishable items, can tolerate longer transit times associated with sea freight without compromising their quality or effectiveness upon arrival. This is advantageous for maintaining product integrity during extended shipping durations.

Overall, the decision to ship clay bars by sea is driven by considerations of cost-efficiency, capacity for bulk orders, environmental impact, and logistical suitability for handling larger volumes over longer distances.
