Air Freight vs Sea Freight: How to Choose for Import & Export

In today’s global trade era, air freight and sea freight are the two most common international shipping methods. Many businesses often face the same question when arranging import-export logistics: “Should I choose air freight or sea freight?” The decision goes beyond cost—it involves delivery speed, cargo type, shipping risks, and long-term strategy. This article compares their advantages, disadvantages, cost differences, and transit times, offering professional advice to help companies select the most suitable logistics solution.
 

What’s the difference between Air Freight and Sea Freight?

In international logistics, choosing air or sea freight depends on factors such as speed, cost, and cargo characteristics—all of which impact the final decision.

Transit Time

Air freight is known for speed—shipping from Taiwan to the U.S. takes only 2–5 days. Sea freight, depending on the route and port congestion, usually takes 15–45 days.

Conclusion: For new product launches or urgent shipments like electronics, air freight prevents delays. For stable bulk exports, sea freight reduces long-term costs.

Air Freight vs Sea Freight Transit Time Comparison

Route	Air Freight ✈️	Sea Freight 🚢
Taiwan ↔ China (Shanghai, Guangzhou, Shenzhen)	Approx. 1–3 days	Approx. 3–7 days
Taiwan ↔ Japan	Approx. 1–2 days	Approx. 4–7 days
Taiwan ↔ Korea	Approx. 1–2 days	Approx. 3–5 days
Taiwan ↔ U.S. West Coast	Approx. 2–5 days	Approx. 15–20 days

Shipping Cost

Air freight is more expensive, usually charged by “actual weight or dimensional weight (whichever is higher).” Sea freight is much cheaper, priced by “LCL (Less than Container Load)” or “FCL (Full Container Load),” with lower unit costs.
Conclusion: Small urgent shipments → Air freight is cost-effective; Bulk cargo → Sea freight is most economical.

Air Freight vs Sea Freight Cost Comparison

Mode	Cost Example	Best For
Air Freight ✈️	Taiwan → U.S. West Coast NT$150–250 / kg 100 kg ≈ NT$15,000–25,000	Electronics, precision instruments, medical supplies, high-value urgent shipments
Sea Freight 🚢	Taiwan → U.S. West Coast 20ft Container ≈ NT$30,000–60,000 Capacity: 20–25 tons	Bulk cargo, furniture, construction materials, auto parts

Cargo Type

Air freight suits high-value, urgent, or perishable goods like electronics, precision tools, and pharmaceuticals. Sea freight is ideal for heavy, bulk, or durable goods such as construction materials, furniture, and machinery.
 

How Should Businesses Choose?

For small, high-value shipments—choose air freight (electronics, medical devices, luxury goods). For bulk or heavy goods—choose sea freight (construction, furniture, auto parts) to cut costs. Many companies adopt a dual strategy: urgent shipments by air, regular shipments by sea, balancing speed and cost.
