Air vs sea vs express for sportswear orders: how to choose

Which shipping mode fits which activewear shipment?

Choose by what a late delivery would cost you, then by volume. Express suits samples and urgent cartons, air freight suits launch stock with a fixed date, and sea freight suits planned bulk and replenishment that can spend several weeks in transit.

Door-to-door time is the only time that matters for a launch. A sea quote that names only the port-to-port sailing leaves out pickup, export clearance, consolidation, import clearance and delivery to your warehouse.

How is chargeable weight worked out for bulky apparel?

Carriers charge for space as well as weight. IATA’s general rule for air cargo divides the volume in cubic centimetres by 6,000 and bills whichever is higher, volumetric or actual weight, so a cubic metre of cartons bills as at least about 167 kg. Express couriers set their own divisors: FedEx divides cubic inches by 139, close to 5,000 cm³ per kilogram, so the same carton bills heavier by express.

Take a hypothetical 60 × 40 × 40 cm carton of hoodies weighing 14 kg. Its volume is 96,000 cm³, or 0.096 m³. Folded performance tees pack densely and may bill on actual weight; bulky fleece is more likely to bill on volume. Ask the factory for carton dimensions, gross weights and pieces per carton by size before requesting quotes, because the packing plan sets the chargeable weight.

When is sea freight the right choice for a first order?

When the goods can arrive weeks later without endangering a launch, and the shipment is large enough to absorb fixed charges. Less-than-container-load (LCL) freight is commonly priced per cubic metre or per tonne, whichever is greater, and many forwarders apply a one-cubic-metre minimum plus origin and destination fees. For a handful of cartons, those fixed charges can erase the saving over air.

Sea freight also asks more of the packing. LCL cartons are consolidated and stacked with other cargo, and long voyages expose them to moisture and condensation. Specify strong export cartons, pack garments dry in protective polybags, and ask your forwarder whether desiccants are advisable for cotton fleece on long routes. Book early: consolidation warehouses close at a cut-off for each sailing, and cartons that miss it wait for the next vessel.

What customs data must be ready before the goods move?

Every mode needs a commercial invoice and packing list that match the cartons, with each line described precisely and classified under the right tariff heading; knitted activewear falls within HS chapter 61. Advance security filings make much of this data due before departure, not on arrival.

Express couriers usually clear the goods themselves and bill duty to the receiver unless the sender has prepaid it. Agree who pays before the first sample ships, so a parcel is not held or refused at the door.

• European Union: an entry summary declaration in ICS2 is required for all goods before arrival, and air cargo needs a minimum data set before loading. ICS2 publishes a list of “stop words” too vague to accept, so write “men’s knitted polyester training shorts” rather than a generic term.
• United States, sea freight: the importer’s security filing to CBP is due at least 24 hours before the cargo is loaded aboard the vessel at the foreign port.
• United States, any mode: since 29 August 2025, low-value shipments from every country have lost duty-free de minimis treatment, so even a sample parcel can owe duties, taxes and fees.

Who should book the freight: you or the factory?

The Incoterms rule decides. The ICC reserves four rules, FAS, FOB, CFR and CIF, for sea and inland waterway transport; the others work for any mode. For air or express, quote FCA at a named place rather than FOB, and your forwarder books the main carriage. Under CPT, CIP or DAP the seller books it, and under DDP the seller also pays import duties and taxes.

Write the rule and named place, the transport mode, who insures the goods and who handles import clearance on every quotation. For samples, many buyers give the factory their own courier account number, so parcels move on the buyer’s rates and the buyer controls how duty is billed.

How do you plan a launch date around production and transit?

Work backwards from the launch, and start the transit clock only when cartons are packed. SenLin quotes production at 15 working days for standard styles and 20–25 working days for custom orders, counted after the order, materials, artwork and sample are confirmed. Transit, clearance and delivery come on top; SenLin ships by sea freight, air freight or express courier and quotes each shipment separately, without published transit times.

Factory and port calendars matter too. The Spring Festival and the National Day holiday in early October close many factories and squeeze freight capacity on either side. If one date is fixed, consider splitting the order: fly the sizes and colours needed for launch and send the balance by sea. Agree the split before packing, so each shipment has its own cartons, packing list and invoice.

• Approvals: sample, materials, artwork and labels signed off.
• Production: working days, adjusted for the factory calendar.
• Final inspection, packing and measured carton dimensions.
• Pickup, export clearance and the carrier’s cut-off.
• Main carriage, import clearance and duty payment.
• Delivery, receiving checks and a buffer before launch.
