Freight shipping concept

Freight & Air Cargo Basics

When a shipment is too large or heavy for small-parcel networks, shippers look at freight modes: less-than-truckload (LTL), full truckload (FTL), ocean, or air cargo. This primer defines terms so you can speak with forwarders knowledgeably.

LTL vs FTL

LTL consolidates pallets from multiple shippers on shared trailers. FTL dedicates a trailer to one shipper’s load. LTL pricing often depends on freight class, density, and accessorials (liftgate, residential delivery, inside delivery).

Air cargo concepts

Air freight prioritizes speed for high-value or perishable goods. Airport-to-airport service differs from door-to-door products. Security screening and dangerous-goods declarations are common requirements.

Preparation tips

  • Palletize and stretch-wrap to prevent tipping
  • Mark center of gravity and handling orientation
  • Confirm appointment delivery windows for businesses
  • Ask about insurance vs carrier liability limits

Smaller parcels still belong in parcel carrier guides. Oversized retail “freight” counters at local stores vary—call those businesses directly if you need a quote.

We do not broker freight or accept cargo.

Accessorial charges to watch

Liftgate, residential delivery, limited access locations, inside delivery, and appointment delivery can each add cost. Ask for an all-in quote. Photograph pallet height and wrap quality before pickup to defend against damage disputes.

NMFC classification (high level)

LTL freight classes relate to density and liability characteristics. Misdeclaring class creates rebills. If you are new to freight, a forwarder can help classify—still verify you understand the bill of lading you sign.

Practical notes on Freight & Air Cargo Basics

Readers use this page while comparing real-world providers. Keep a short checklist of your constraints—budget range you will confirm elsewhere, deadline, package weight, whether you need multi-carrier receiving, and whether remote scanning matters. Bring that checklist to any vendor you contact so sales conversations stay grounded.

Regulations and carrier products change. Before you act on any step that involves identity documents, money, or legal filings, confirm details on the official agency or carrier site.
