When is air freight worth it for basics?

Short answer: Air freight is usually worth it only when the cost of being out of stock, or the value of arriving early, is larger than the extra freight cost per unit. For basics, the unit value is often low compared with the weight and volume, so moving a whole order by air can remove much of the margin. Sea freight takes longer and has more steps, such as container loading, port handling and possible congestion, but is usually far cheaper per unit for full orders. Air is commonly charged on the greater of actual and volumetric weight, so bulky goods such as hoodies cost more to fly than their weight suggests. A practical rule is to compare the extra landed cost of air per unit with the margin you would lose during a stock-out, including marketplace ranking or customer loss where relevant. Situations that often justify air are urgent replenishment of fast-selling sizes, a launch date that cannot move, or samples and small top-up quantities. A split shipment, with a small share of the order by air to cover the gap and the rest by sea, often balances cost and timing. The Incoterms rule should suit the mode: ICC Academy guidance notes that FOB is for sea and inland waterway transport only, while FCA works for any mode, including air. Planning reorders earlier is usually cheaper than using air regularly.

When air may be worth it

• Stock-out of fast-selling sizes.
• Fixed launch or promotion dates.
• Samples and small top-ups.

When sea is usually better

• Full replenishment orders.
• Bulky, low-value items.
• Orders planned with enough lead time.

A worked example

As an illustration, a brand could ship enough of its top three sizes by air to cover the expected gap until the sea shipment arrives, and send the remaining cartons by sea, with both shipments under clearly separate packing lists.

What to agree with the factory

Agree which cartons go by air, packing and labelling for each shipment, and the ready date for each part. Ask the forwarder for quotes on both modes using actual carton sizes and weights.

Reducing the need for air

Most urgent air shipments for basics come from late reorders. Setting reorder points that cover the full sea lead time plus a safety margin, and reviewing them each month, usually reduces how often air is needed.

Limits

Freight rates and transit times change with season and capacity. Use current quotations, not past rates, for each decision.

Facts, recommendations and uncertainty

Established: FCA suits any transport mode while FOB is for sea and inland waterway only. Common practice: air freight is often charged on the greater of actual and volumetric weight; confirm the basis with your forwarder. Recommendation: compare extra air cost per unit with the margin lost in a stock-out and consider split shipments. Uncertain: current freight rates and transit times.
