The cost of sea freight is lower than other methods of international shipping. When importing products, you’re looking to maximise your profits by minimising your costs as much as possible. Here are some tips for shipping via sea that will save you money: Multiple shipments from multiple suppliers can be combined into a single shipment if they are within a reasonable distance of one another. Adding more items to your order does not necessarily increase shipping costs and, if it does, the increase is not huge. It will improve shipping costs, since the cost per unit will be lower. Holidays or peak times are not the best times to ship. Similarly to other industries, the shipping industry has its busiest times of year.
