The Shipper's Field Guide: How Freight Actually Moves
This is an independent educational guide, not the website of any carrier, freight forwarder, customs broker, or regulator.
aerolink-logistics.com is an independent, non-commercial field guide to freight and logistics. It explains how goods move by air, sea, road, and rail, what documents a shipment needs, how packing, labeling, and dangerous-goods rules work, and the vocabulary of the industry. It sells nothing, arranges no shipments, accepts no advertising, recommends no specific carrier or service, and has no affiliation with IATA, ICAO, the FAA, the IMO, the FMC, the WCO, CBP, or the ICC, or any other named organization.
Freight rarely moves in one hop. A shipment is handed between parties, each responsible for a stage, a document, or a rule. This guide walks you through that chain so you can ask better questions before you pay anyone. You will meet the five concepts that appear on nearly every shipping document, the organizations that write the rules for air and sea, a table matching your situation to the source that helps most, how quotes are built, and the misunderstandings that cost first-time shippers money.
1. Why Shipping Freight Is a Chain, Not a Single Trip
Freight is organized as a sequence of handoffs. Goods are picked up at origin, consolidated with other shipments, moved on a line-haul leg (the long-distance flight, vessel voyage, or truck run), cleared through customs where a border is crossed, deconsolidated at destination, and delivered to the final address. Each stage has its own paperwork and its own responsible party. A missed document at consolidation can stall the line-haul; a mislabeled pallet can delay customs release. Understanding the chain tells you where to look when something goes wrong.
2. Five Working Concepts
Bill of lading. A contract of carriage and receipt for the goods. It names the shipper, consignee, and cargo. Illustrative example: Northgate Tools issues a bill of lading naming Harbor City Roasters as consignee for a pallet of hardware.
Consignee. The party entitled to receive the shipment. Illustrative example: Harbor City Roasters is the consignee on a delivery to its warehouse.
Freight forwarder. A company that arranges transport, documentation, and customs steps on your behalf. Illustrative example: Northgate Tools hires a forwarder to book air cargo and file the export declaration.
Incoterms rule. A standard trade term defining who arranges and pays for carriage, insurance, and duties. Illustrative example: Northgate Tools sells under a rule where the buyer arranges the main carriage.
HS code. A numeric classification for traded goods, used to determine duty and controls. Illustrative example: Harbor City Roasters classifies green coffee under an HS code for unroasted coffee.
3. Who Sets the Rules in the Air
IATA runs the air cargo industry's standards programs, including documentation and dangerous-goods guidance that airlines and forwarders follow. The International Civil Aviation Organization is the UN agency behind the Chicago Convention framework for international air navigation, and it publishes standards and recommended practices that states adopt. The Federal Aviation Administration regulates civil aviation in the United States, issuing rules and guidance that affect carriers operating to, from, or within the country. Together they shape what can fly, how it is described, and what paperwork accompanies it.
4. Who Sets the Rules at Sea and at the Border
The International Maritime Organization writes the global safety and pollution conventions for shipping, covering vessel construction, dangerous goods, and environmental protection. The Federal Maritime Commission oversees US ocean shipping, including the conduct of carriers and intermediaries in the waterborne trade. The World Customs Organization maintains the Harmonized System, the tariff nomenclature that national codes are built on. U.S. Customs and Border Protection publishes the basic import and export guidance for the United States, explaining entry, classification, and clearance steps.
5. A Decision Table for Your Situation
| Your situation | What matters most | Source that helps most |
|---|---|---|
| Small business importing its first pallet | Classification, duty, and entry paperwork | U.S. Customs and Border Protection |
| Online seller shipping a parcel abroad | Documentation and carrier conditions | IATA |
| Company moving urgent parts by air | Airworthiness and operating rules | The Federal Aviation Administration |
| Household moving furniture overseas | Ocean safety and carrier conduct | The International Maritime Organization and the Federal Maritime Commission |
| Manufacturer exporting under its first trade terms | Who arranges and pays for each leg | The International Chamber of Commerce |
6. How a Price Quote Is Built
Air freight quotes usually turn on chargeable weight, which compares actual weight with volumetric weight so light but bulky cargo is priced by the space it occupies. Ocean freight splits into full-container load, where you book a whole container, and less-than-container-load, where your cargo shares a container with others. Trucking quotes add accessorial charges for services beyond the basic line-haul, such as waiting time or special handling. Illustrative example: a shipment of 12 cartons weighing 180 kg actual and 240 kg volumetric would be quoted on the higher figure, with a liftgate fee added at delivery.
7. Common Misunderstandings
The cheapest quote is the final price. Quotes often exclude accessorials, duties, and clearance fees that appear later.
The carrier is always the company you booked with. Forwarders and brokers arrange carriage, so the airline or vessel line may never deal with you directly.
Customs clearance is the carrier's job. Carriers move goods; entry and duty obligations rest with the importer or its broker.
Insurance is included by default. Standard carriage terms usually limit liability, so cover must be arranged separately.
A tracking number means the shipment is moving. A number often appears at booking, before the goods physically leave.
8. Frequently Asked Questions
Do I need a freight forwarder?
Not always, but a forwarder helps when you cross borders, need documentation, or lack carrier accounts.
What is the difference between a bill of lading and a waybill?
An order bill of lading is negotiable and can transfer title; a waybill is non-negotiable and names the consignee directly.
Who decides the HS code?
The importer is responsible for correct classification, though a customs broker can advise.
Can I ship dangerous goods as a small business?
Yes, but only with proper classification, packing, and documentation under the applicable air or sea rules.
What does Incoterms change?
It sets which party arranges and pays for carriage, insurance, and duties at each point.
Where do I check US import rules?
U.S. Customs and Border Protection publishes the basic import and export guidance.
