13. International Transport
Teaching rewrite of international transport practice, law, documents, and cargo insurance. Pedagogical summaries only — not legal, logistics, or insurance advice. Treaty memberships and liability limits change (limits are revised periodically); figures marked illustrative are for learning only.
Introduction
How goods move decides their price, delivery speed, and risk of loss. Big traders run logistics departments; smaller ones rely on freight forwarders. Either way, the person booking transport must know exactly what the sale contract promised: pickup place, delivery place, who pays loading and handling, packaging, and insurance.
Transport law is a patchwork of treaties by mode, each with limited carrier liability and long lists of carrier defences. In practice, a cargo owner recovers losses from insurance, not from carriers. So the safest rule is: insure fully, including “gap” cover where another party’s insurance may fall short.
This lesson covers:
- Transport management: volume, cost, speed, packaging, customs, payment links
- The conventions by mode and what they mean for carrier liability
- Charter parties, freight forwarders, and transport documents (especially the bill of lading)
- Sea, container/multimodal, air, road, and rail in practice
- Cargo insurance: duty vs need to insure, insurable interest, open cover, ICC (A)/(B)/(C)
Assumptions. Cross-border B2B shipments. Incoterms® details are in Lesson 3; documentary credits in Lesson 9.
13.1 Transport management
| Lever | Idea | Practical move |
|---|---|---|
| Volume | Bigger, regular shipments get lower rates | Consolidate sales into one shipment; door-to-door contracts; shippers’ councils for joint bargaining |
| Cost in the price | Transport can be a large share of landed cost, especially for low-value goods | Choose the Incoterm deliberately — it decides who buys transport |
| Transport as profit centre | Sellers quoting EXW/FCA/FOB give the transport business away | A competent seller can quote CIF/CIP/DDP and earn on managing transport |
| Speed & reliability | Late goods lose customers, whoever is at fault; transit time ties up working capital | Fewer hand-overs (one party controls the chain) means fewer delays |
| Inventory | Just-in-time supply cuts warehousing but demands reliable transport | Match mode to stock policy |
| Packaging | Cheap freight modes may need costly packaging and suffer more damage | Ask the buyer early which mode it will use |
| Customs | Simplified procedures for air, postal, and some road/rail regimes speed clearance | Factor clearance time into mode choice |
| Payment | A credit calling for a marine on-board B/L rules out air shipment | Align transport documents with the credit (Lesson 9) |
Transport economies are best when one party buys the whole move (EXW for the buyer, DDP for the seller): more volume with one provider and fewer hand-overs.
13.2 Conventions and carrier liability
| Mode | Regime | Status (simplified) | Liability limit (indicative) |
|---|---|---|---|
| Sea | Hague Rules (1924) | Widely adopted; criticised for low limits and many exemptions | Per package (old fixed amounts) |
| Hague-Visby Rules (1968, amended) | Most major trading nations | 666.67 SDR per package or 2 SDR per kg, whichever is higher | |
| Hamburg Rules (1978) | In force since 1992, but few major shipping nations | 835 SDR per package or 2.5 SDR per kg | |
| Rotterdam Rules (2008) | Door-to-door with a sea leg, e-documents — not yet in force | 875 SDR per package or 3 SDR per kg | |
| Air | Montreal Convention (1999) | In force since 2003; most trading nations | About 26 SDR per kg (revised periodically by ICAO) |
| Warsaw system (1929 + protocols) | Where Montreal not ratified | Lower limits | |
| Rail | COTIF / CIM | Europe and neighbouring countries | 17 SDR per kg |
| Road | CMR (1956) | Virtually all of Europe and beyond | 8.33 SDR per kg |
| Multimodal | UN Convention (1980) | Not in force | — |
| UNCTAD/ICC Rules for Multimodal Transport Documents (1992) | Contractual rules used in FIATA and BIMCO (MULTIDOC) documents | Contractual |
SDR = Special Drawing Right, the IMF’s basket currency (roughly USD 1.3–1.4; check the current rate).
Carrier liability in principle
- Money cap per package or per kg under every regime.
- Carrier’s duty (Hague / Hague-Visby): due diligence on seaworthiness, fitness of the holds, proper loading, stowage, and discharge.
- Carrier’s defences (Hague / Hague-Visby): perils of the sea, fire, war, strikes, acts of God; inherent defects or insufficient packing; negligence in navigating or managing the ship by master or crew.
- Time bars and notice: note visible damage in writing on the delivery receipt immediately, and notify the carrier and the insurer.
Worked example: the liability gap
Ten pallets, 2,000 kg in total, worth USD 80,000, are lost at sea under Hague-Visby. Assume 1 SDR = USD 1.33 (illustrative).
| Basis | Calculation | SDR |
|---|---|---|
| Per package | 10 × 666.67 | 6,667 |
| Per kg | 2,000 × 2 | 4,000 |
| Limit (higher of the two) | 6,667 ≈ USD 8,870 |
Even if the carrier is liable, the owner recovers about 11% of the cargo’s value — and the carrier may have a defence. That gap is why cargo is insured.
13.3 Charter parties
| Charter type | Who runs ship and crew | Charterer’s role |
|---|---|---|
| Voyage | Shipowner | Hires space for one voyage |
| Time | Shipowner | Controls cargo bookings for a period |
| Bareboat (demise) | Charterer | Effectively operates the ship |
A charter party is only a contract of carriage between shipowner and charterer — not a receipt and not a document of title, so it cannot be endorsed like a bill of lading. Charter parties allow more freedom of contract (e.g. lower owner liability) than bills of lading governed by a convention.
Bills of lading issued subject to a charter party create questions for the cargo buyer:
- Whom to sue — shipowner or charterer? Under which contract?
- Acceptability — are charter-party B/Ls acceptable under the sale contract and the credit? (UCP 600 treats them separately.)
- Incorporation — a B/L may incorporate charter-party terms, including an arbitration clause, so a court case by the buyer could be dismissed in favour of arbitration. Incorporation must be clear and must not contradict the B/L or a mandatory convention.

13.4 Freight forwarders
A forwarder is to cargo what a travel agent is to passengers: it knows rates and routes and builds the best package — booking freight, preparing export and customs documents, arranging insurance, and paying port and terminal charges. Small exporters often ask their forwarder for costs before quoting a price.
| Acting as | Legal position | Liability for subcontractors |
|---|---|---|
| Agent | Arranges third-party services on the customer’s behalf; customer contracts with them directly | Generally not liable (owes duties of care and information) |
| Principal | Contracts directly with the customer and subcontracts; issues one invoice | Generally liable for subcontractors |
| Hybrid | Agent for some tasks, principal for others | Depends on the task |
| Specialist | Function |
|---|---|
| Consolidator / NVOCC | Groups small shipments into full containers; NVOCCs issue their own B/Ls on ships they do not own |
| Multimodal transport operator (MTO) | One-stop door-to-door logistics |
| Customs broker | Files declarations, pays duties; usually bonded — give clear limits on duties/fines |
| Port / terminal agent | Handles transfer between modes at a port or airport |
| Air freight (IATA) agent | Processes air cargo, may issue air waybills, often clears customs |
| Road haulage broker | Matches shippers with small road carriers, paid by commission |
| Loading broker | Agent of the shipowner, selling space and supervising loading |
13.5 Shipping documents
| Document | Purpose | Watch-out |
|---|---|---|
| Commercial invoice | Bill for the goods; basis for customs duty in many countries | Double invoicing (a lower invoice for customs) is fraud with heavy penalties |
| Inspection certificate | Independent agency confirms quality/quantity | Often required under L/Cs |
| Certificate of origin | Country of production, usually chamber-certified | Needed for preferential tariffs |
| Insurance certificate / policy | Proof of cover (CIF/CIP) | A credit demanding a policy will not accept a certificate |
| Packing list | Weight, volume, contents, packaging per package | |
| Export licence | Government permit for controlled goods | Hazardous and sensitive (e.g. dual-use) goods may face quotas |
| Consular invoice | Official invoice form required by some importing countries |
13.6 The bill of lading and other transport documents
The marine bill of lading — three functions
- Control of the goods — the lawful holder of an order B/L is entitled to delivery; endorsement transfers control, so goods can be sold in transit and banks can lend against it.
- Evidence of the contract of carriage — on usual terms, as the CIF/CFR seller must provide.
- Receipt — goods received in apparent good order. A received-for-shipment B/L becomes acceptable for documentary sales only once noted shipped on board. Notations of damage make it claused (unclean).
For the buyer, a clean on-board B/L shows the seller shipped apparently conforming goods, gives the right to demand delivery and to sue the carrier, and allows resale and financing. For the seller, it means payment as soon as goods are properly shipped. (UCP 600: the word “clean” need not actually appear on the document.)
Problems:
- Goods arrive before the B/L — common on short routes and in oil. Delivering without an original exposes the carrier, so it releases against a letter of indemnity (LOI), usually backed by a bank.
- A marine B/L covers only the sea leg; door-to-door moves need a multimodal document.
Other transport documents
| Document | Mode | Negotiable? | Note |
|---|---|---|---|
| Order B/L | Sea | Yes | Security for banks; enables resale in transit |
| Straight B/L | Sea | No | Named consignee; shipper may change consignee until it is irrevocable — weak bank security |
| Sea waybill | Sea | No | Receipt + contract, not title; consignee collects without an original — good when goods outrun documents |
| Multimodal transport document | Two or more modes | Can be | May evidence receipt at an inland terminal, not “on board” |
| Air waybill (AWB) | Air | No | IATA form; master AWB from the airline, house AWB from the consolidator |
| Rail consignment note | Rail | No | CIM in Europe |
| Road consignment note | Road | No | CMR |

13.7 Sea transport in practice
Market structure
| Type | Rates | Service |
|---|---|---|
| Conferences | Common published rates (cartel-like, historically exempt from competition law) | Regular scheduled service |
| Outsiders / independent lines | Usually cheaper | Large ones match conference quality |
| Tramps | Negotiated per voyage through brokers | Bulk cargo, flexible routes |
The trend is toward individual confidential service contracts. The EU ended conferences’ antitrust exemption in 2008; liner alliances (vessel-sharing agreements) now dominate container trades, with exemptions under separate rules.
Freight and charges
- Freight on weight or measure (W/M): the carrier charges per tonne or per cubic metre, whichever yields more (commonly 1 m³ treated as 1,000 kg).
- Surcharges: BAF (bunker/fuel adjustment) and CAF (currency adjustment) can change at short notice — include price adjustment clauses in sale contracts; also heavy-lift and long-length surcharges.
- Freight prepaid (seller pays, e.g. CIF) or freight collect (buyer pays on arrival).
- Terminal/handling charges are often outside freight; the Incoterm decides who pays.
Liner terms vs Incoterms®
Liner terms belong to the carriage contract (shipper ↔ carrier) and decide whether loading/unloading costs are in the freight. Incoterms® belong to the sale contract (seller ↔ buyer). The party buying transport must make sure the liner term does not contradict the sale’s Incoterm.
| Liner term | Loading | Unloading |
|---|---|---|
| Ex quay | Carrier loads from anywhere alongside | Carrier lands, sorts, sometimes stores |
| Under ship’s tackle | Shipper brings goods under the crane | Carrier only places goods on deck |
| Free in / free out (FIO) | Shipper loads and stows | Consignee unstows and discharges |
Stevedores handle cargo and bill one party; they do not split charges — one reason Incoterms® 2010 moved FOB/CFR/CIF delivery from the “ship’s rail” to on board.
13.8 Containers and multimodal transport
- Standard boxes 8 ft wide and high, 20 or 40 ft long (10 ft less common); volume measured in TEU (twenty-foot equivalent units). Containers cut handling time from days to hours and reduce damage and theft.
- Always check the internal dimensions before packing.
- FCL (full container load): empty box delivered to the shipper, stuffed, sealed (a broken seal signals tampering), returned. LCL (less than container load): goods delivered to a terminal, consolidated with others, de-consolidated at destination.
- Charges: freight (often including the box), terminal handling charges at both ends, and detention/demurrage penalties if boxes are kept too long.
Use container Incoterms®
| Port-based term | Container / multimodal equivalent |
|---|---|
| FOB | FCA |
| CFR | CPT |
| CIF | CIP |
Containers are handed over at the shipper’s premises or an inland terminal, so dividing risk “on board the vessel” leaves an exposed gap between hand-over and loading — and makes the seller pay costs it no longer controls. Use FCA/CPT/CIP.
13.9 Air transport
Air freight is roughly 1% of world trade by weight but far more by value — perishables, urgent goods, and high-value items (jewellery, pharmaceuticals, art) move by air. Despite higher freight, air can be competitive overall:
- Insurance — often about half the sea rate (e.g. ~0.3% vs ~0.6–0.7% of value)
- Customs duty — sometimes assessed on gross weight; lighter packaging lowers it
- Packaging — lighter and cheaper
- Inventory — less warehousing, tax, insurance, and obsolescence
- Financing — faster delivery means faster payment
Practice. Cargo flies in passenger aircraft, combis, or freighters. Use FCA (named airport terminal) — “FOB airport” was abandoned long ago. IATA cargo agents sell space for airlines; consolidators issue house AWBs (like NVOCCs at sea) and often offer door-to-door service. Cargo moves in ULDs (unit load devices). Ask for guaranteed shipment times. Dangerous goods rules (IATA DGR, updated yearly) are strictly enforced — wrong declarations bring heavy penalties.
Chargeable weight
Carriers charge the higher of actual and volumetric weight:
| Mode | Common conversion (illustrative) |
|---|---|
| Sea (W/M) | 1 m³ = 1,000 kg |
| Road | 1 m³ ≈ 333 kg (varies by market) |
| Air | 6,000 cm³ = 1 kg → 1 m³ ≈ 167 kg |
Worked example: chargeable weight
A consignment weighs 500 kg and measures 3.2 m³.
| Mode | Volumetric | Actual | Chargeable |
|---|---|---|---|
| Sea | 3.2 m³ → 3.2 freight tonnes | 0.5 t | 3.2 freight tonnes (charged by volume) |
| Road | 3.2 × 333 ≈ 1,066 kg | 500 kg | 1,066 kg |
| Air | 3.2 × 167 ≈ 534 kg | 500 kg | 534 kg |
Light, bulky goods are charged on volume — compact packaging saves money.
Worked example: air vs sea total cost
Goods worth USD 200,000; inventory carrying cost 20% a year; sea transit 35 days door-to-door vs 5 days by air (illustrative).
| Cost | Sea | Air |
|---|---|---|
| Freight | 2,500 | 12,000 |
| Insurance (0.7% vs 0.3%) | 1,400 | 600 |
| Packaging | 1,500 | 600 |
| Capital tied up in transit (200,000 × 20% × days/365) | 3,836 | 548 |
| Buffer warehousing at destination | 2,000 | 0 |
| Total | 11,236 | 13,748 |
Sea still wins by about USD 2,500 here — but the gap is far smaller than the freight difference (9,500) suggests. Add one lost sale from a stock-out or a higher-value product, and air can win.
13.10 Road and rail
| Road | Rail | |
|---|---|---|
| Strength | True door-to-door, no transhipment; flexible; Ro-Ro ferries | Very heavy loads, bulk ore and liquids; competitive per tonne; ideal with private sidings |
| Weakness | Limited payload (often ~40 t, national limits apply); driver costs vary by country | Fewer access points; gauge and clearance differences force transhipment |
| Law | CMR | COTIF / CIM |
| Customs transit | TIR carnet: sealed trucks cross TIR countries without full inspection at each border | Rail transit regimes |
| Pricing | Weight vs volume ratio (see chargeable weight) | Usually by weight, express vs slow service |
Road-rail combinations (trailers on wagons) add flexibility.
13.11 Cargo insurance
Duty vs need to insure
- Contractual duty: only under CIF and CIP does the seller have to insure for the buyer.
- Commercial need: everyone at risk at some point should be insured — the Incoterm sets where risk passes.
Why not split cover at the risk point?
Splitting cover (seller to the ship, buyer from the ship) creates gaps, makes it hard to prove where damage happened (both insurers may refuse), and costs more than one warehouse-to-warehouse policy.
If the seller insures only up to loading and the goods are damaged at sea, the buyer may refuse to pay — leaving the seller with a lawsuit instead of an insurance claim. Sellers paid after arrival should insure their contingency interest for the whole transit.
Contingency / gap / difference-in-conditions (DIC) insurance tops up when the other party’s cover is too small, excludes likely risks, or is placed with a local insurer that some countries require by law.
Insurable interest
You can claim only if you had an insurable interest (ownership or risk) when the loss happened — generally the seller before the risk point, the buyer after. Policies can be assigned (e.g. CIF seller endorses the policy to the buyer).
Open cover and floating policies
| Type | How | Note |
|---|---|---|
| Open cover / open policy | General terms for all shipments in a period; limit renews after each voyage | Insurer issues certificates per shipment |
| Floating policy | Total sum insured reduced by each declared shipment | |
| Single (facultative) policy | One shipment |
Cost and clauses
- Indicative premiums: air ~0.3%, sea ~0.6–0.7%, long road/rail legs in difficult regions up to ~2% of value.
- Institute Cargo Clauses: (A) broadest (“all risks” minus exclusions), (B) and (C) named perils only. Even (A) excludes war and strikes (added by separate War and SRCC clauses), insufficient packing, delay, ordinary wear and tear, and carrier insolvency.
- Incoterms®: minimum sum insured 110% of the contract price. Under Incoterms® 2010 both CIF and CIP required at least (C); Incoterms® 2020 raised CIP to (A) while CIF stays at (C).
- If the buyer expects a high margin, specify 120–130%, (A) cover, and SRCC/war in the sale contract.
Worked example: CIF insurance
CIF price USD 100,000; insured value 110% = USD 110,000; sea premium 0.65% → premium USD 715. Adding war/SRCC at, say, 0.05% → 110,000 × 0.0005 = USD 55 more.

Takeaways
- Tell the forwarder/carrier exactly what the sale contract requires
- Carrier liability is capped and full of defences — insure warehouse-to-warehouse, with gap cover where needed
- Know the regimes: Hague-Visby, Hamburg, (Rotterdam not in force), Montreal, CMR, COTIF/CIM
- Order B/L = control + contract + receipt; sea waybill = no title, fast release; AWB never negotiable
- Containers → FCA / CPT / CIP, not FOB/CFR/CIF
- Freight is charged on the higher of actual vs volumetric weight; watch BAF/CAF
- Air can win on total cost, not freight alone
- Only CIF/CIP oblige the seller to insure: 110%; Incoterms® 2020 CIP needs (A)
