Air freight and sea freight solve different shipping problems. One is usually chosen for speed and smaller packages; the other can be a better fit for bulky, heavy or less urgent cargo. The right choice depends on what you are shipping, how quickly you need it and how the shipment will be priced.

Before deciding, check Legacy Shipping’s current service and rate information because active pricing and available routes can change.

When air freight makes sense

Air freight is commonly used for online-shopping packages, clothing, electronics, small auto parts, documents and items where faster movement matters. Air cargo is generally priced around weight or chargeable weight, so dense packages can be straightforward to estimate.

• Better for smaller and time-sensitive items.
• Useful for regular online-shopping orders.
• Usually easier to estimate when package weight is known.
• Can become expensive for large, lightweight boxes if dimensional weight applies.

When sea freight makes sense

Sea freight is often considered for larger household items, bulk purchases, business stock, barrels, boxes, furniture or other shipments where speed is less important than moving more volume economically.

• Better suited to bulky or heavy shipments in many cases.
• Pricing may be based on cubic volume rather than pounds.
• Transit and processing generally take longer than air.
• Large or commercial shipments may require more planning and documentation.

Weight vs volume: the big pricing difference

Air and sea freight are not always priced using the same measurement. Air shipments often focus on actual or dimensional weight. Sea cargo is frequently priced by cubic feet or another volume measurement.

That means a lightweight but very large item can be expensive by air because of the space it occupies, while a compact heavy item may behave differently. Always compare the specific package, not just a generic “per pound” number.

Customs applies to both shipping methods

Choosing sea instead of air does not automatically remove Jamaican Customs requirements. Value, item classification, documentation and applicable import rules still matter. Jamaica Customs’ eCommerce information explains the US$100 de minimis threshold and the circumstances in which duties and taxes can apply.

See the official Jamaica Customs eCommerce guidance for current rules.

Which option is better for online shopping?

For a few regular packages from Amazon, Temu, SHEIN or similar stores, air freight is often the simpler choice because the items are relatively small. For furniture, larger business orders or bulky household goods, sea freight may deserve a closer look.

A simple decision checklist

• Need it sooner? Start by checking air.
• Large or bulky? Compare sea pricing.
• Know the weight but not dimensions? Ask before assuming the cost.
• High-value item? Budget for possible Customs charges.
• Unsure whether Legacy accepts the item? Ask support first.
