When should I use air freight instead of sea freight?

Air freight is the right choice when any of the following apply: (1) the goods are time-sensitive (urgent spare parts, perishable food, seasonal fashion, product launches); (2) the goods have a high value-to-weight ratio, making the freight cost a small percentage of the product value (electronics, pharmaceuticals, luxury goods); (3) the shipment is small (under 150 kg or 1 cbm), where the minimum charges for sea freight make it uneconomical; (4) the goods are perishable and require fast transit to maintain quality (flowers, fresh seafood, certain chemicals). As a rough rule of thumb, if air freight represents less than 15-20% of the landed cost of the goods, and speed is important, air freight may be justified.

What is the difference between FCL and LCL, and when should I use each?

FCL (Full Container Load) means you book an entire container - you pay for the full container regardless of whether you fill it. LCL (Less than Container Load) means your goods are consolidated with other shippers' cargo in a shared container. Use FCL when your shipment is large enough to fill or nearly fill a container (above 15 cbm as a general rule), when you need shorter transit time (no consolidation/deconsolidation delays), or when your cargo is sensitive and you want to avoid co-loading with other products. Use LCL when your shipment is too small for a full container and the additional 3-7 days of transit time for consolidation is acceptable. Compare the all-in costs: sometimes a 20-foot FCL is cheaper than an LCL shipment of 10+ cbm due to minimum charges and handling fees.

What level of cargo insurance should I take?

For most international shipments, Institute Cargo Clauses (A) - all-risks coverage - is recommended. Clauses (B) and (C) only cover named perils and leave significant gaps (theft, pilferage, breakage, and water damage are excluded under C-clauses). The carrier's liability under transport conventions is limited to a fraction of the goods' value - for maritime transport under the Hague-Visby Rules, just 2 SDR per kg (approximately EUR 2.50/kg). If you are shipping EUR 50 per kg electronics, the carrier's maximum liability covers only 5% of your loss. Always insure for 110% of CIF value. If you ship regularly, an open (floating) policy is more efficient and cost-effective than insuring each shipment individually.

Do I need a freight forwarder or can I book transport directly with carriers?

You can book directly with carriers, but a freight forwarder adds significant value, especially for international trade. Freight forwarders aggregate volume from multiple shippers, giving them negotiating power for better rates than most individual companies can achieve. They handle the complexity of multimodal routing, consolidation, documentation (B/L, customs declarations, certificates), and regulatory compliance. For LCL shipments, you need a forwarder for consolidation. For FCL, you could book directly with a shipping line, but the forwarder often gets better rates and handles the documentation. The main exceptions are very large shippers with dedicated logistics teams and sufficient volume to negotiate directly. For SMEs, a good freight forwarder is an essential partner.

What is ISPM 15 and what happens if my wood packaging does not comply?

ISPM 15 (International Standards for Phytosanitary Measures No. 15) requires all solid wood packaging materials used in international trade - pallets, crates, dunnage, and other wood supports - to be treated (heat treated to a core temperature of 56 degrees Celsius for 30 minutes, or methyl bromide fumigated) and stamped with the ISPM 15 mark showing the treatment method and the producer's registration number. If your wood packaging does not comply, the consequences can be severe: the shipment may be refused entry at the destination port, quarantined, treated at your expense, re-exported, or destroyed. Many importing countries - including the EU, USA, China, and Australia - strictly enforce ISPM 15. The simplest way to avoid issues is to use ISPM 15-compliant pallets from a certified supplier, or to use alternative materials (plastic pallets, plywood, cardboard) that are exempt from the requirement.

Choosing the right mode of transport

The choice of transport mode is one of the most consequential decisions in an international trade transaction. It directly impacts cost, transit time, risk, and environmental footprint. Each mode has distinct characteristics that make it suited to particular types of cargo, trade lanes, and commercial requirements.

Maritime transport

Maritime transport carries approximately 80% of global trade by volume and remains the most cost-effective mode for large volumes and long distances. It dominates intercontinental trade and is the backbone of supply chains for raw materials, manufactured goods, and consumer products.

Container shipping - FCL and LCL

FCL (Full Container Load): the shipper books an entire container - typically a 20-foot (TEU, ~33 cbm, max ~21 tonnes payload) or 40-foot container (FEU, ~67 cbm, max ~26 tonnes). The container is loaded and sealed at the shipper's premises or warehouse and remains sealed until it reaches the consignee.

Advantages: lower risk of damage and pilferage (sealed container), faster terminal handling, more predictable schedule
Cost: quoted per container. As of 2026, rates on major east-west trade lanes range from USD 1,500 to USD 4,500 per FEU depending on the route and market conditions

LCL (Less than Container Load): when the shipment volume does not justify a full container, goods are consolidated with other shippers' cargo at a Container Freight Station (CFS). The freight forwarder groups multiple LCL shipments into one FCL container.

Advantages: cost-effective for small volumes (under 15 cbm)
Disadvantages: longer transit time (consolidation/deconsolidation adds 3-7 days), higher handling risk, potential delays waiting for consolidation

Specialised containers

Container type	Use case
Reefer (refrigerated)	Perishable goods, pharmaceuticals, chemicals requiring temperature control
Open-top	Oversized or heavy cargo loaded from above (machinery, steel coils)
Flat rack	Heavy or out-of-gauge cargo (vehicles, industrial equipment)
Tank container	Liquid bulk (chemicals, food-grade liquids, wines)
High cube (9'6")	Light, voluminous cargo requiring extra height

Air transport

Air freight is the fastest mode and the preferred choice for high-value, low-weight, time-sensitive, or perishable goods. While it represents only about 1% of global trade by volume, it accounts for roughly 35% by value.

Transit time: typically 1-3 days door-to-door for major trade lanes
Cost: significantly higher than maritime - typically USD 3-8 per kg, compared to USD 0.05-0.15 per kg for sea freight
Best for: electronics, pharmaceuticals, spare parts (urgent), fashion, luxury goods, perishable food (fresh fish, flowers, exotic fruits), dangerous goods requiring special handling, samples and prototypes

E-commerce has driven massive growth in air freight, with dedicated freighter capacity and express integrators (DHL, FedEx, UPS) operating global hub-and-spoke networks optimised for speed.

Road transport

Within Europe, road transport handles the majority of intra-continental freight. It offers door-to-door flexibility without the need for additional handling at terminals.

FTL (Full Truck Load): standard European semi-trailer - 13.6m length, max 33 pallets, ~24 tonnes payload. Transit time: approximately 1 day per 500-700 km
LTL (Less than Truck Load): groupage service for smaller shipments. Handled through networks of hubs and depots. Transit 2-5 days within Europe
Types of trailers: tautliner/curtainside (most common), refrigerated, tanker, flatbed, mega-trailer (100 cbm volume)

Road transport is governed by the CMR Convention (Convention on the Contract for the International Carriage of Goods by Road), which standardises the carrier's liability across most European and neighbouring countries.

Rail transport

Rail transport is experiencing a renaissance in international trade, driven by the China-Europe rail services (connecting China's industrial centres to European cities via the Eurasian landbridge in 12-18 days - roughly half the transit time of maritime at roughly half the cost of air) and by EU sustainability policies encouraging modal shift from road to rail.

Within Europe, intermodal rail (containers or swap bodies on rail wagons) competes with road transport on corridors exceeding 500 km. The EU's TEN-T network and European Rail Traffic Management System (ERTMS) are progressively improving cross-border rail efficiency.

Transit time: 12-18 days China-Europe; 1-3 days intra-Europe (for intermodal services)
Cost: between maritime and air freight
Best for: goods that need faster delivery than maritime but are too heavy or voluminous for air

Rail transport within Europe is governed by the CIM Convention (Convention concerning International Carriage of Goods by Rail), which standardises the rail carrier's liability.

Multimodal transport

Most international shipments involve more than one mode of transport. A container shipped from Shanghai to Munich may travel by sea to Hamburg, then by rail or road to Munich. The key question is: who bears the risk during each leg?

A multimodal transport operator (MTO) - typically a freight forwarder - issues a single multimodal transport document covering the entire journey, assuming liability for the entire carriage. This simplifies the shipper's position compared to arranging separate contracts for each leg.

Multimodal transport is not yet governed by a universally ratified international convention. The Rotterdam Rules (2008) were designed to cover door-to-door carriage but have not entered into force. In practice, freight forwarders' standard terms (often based on the FIATA Model Rules) govern liability.

Transport documents

Transport documents serve multiple critical functions: they evidence the contract of carriage, serve as a receipt for the goods, and in some cases constitute a document of title (enabling transfer of ownership).

Bill of Lading (B/L)

The most important document in maritime trade. The B/L serves three functions:

Evidence of contract of carriage between shipper and carrier
Receipt confirming that the carrier has received the goods as described
Document of title: the holder of the original B/L is entitled to take delivery of the goods. This makes the B/L negotiable - it can be endorsed and transferred

Types:

Shipped/on-board B/L: confirms goods are loaded on the named vessel. Required for L/C transactions
Received-for-shipment B/L: confirms goods received at the terminal, not yet loaded. Less valuable for L/C purposes
Clean B/L: no adverse remarks about the condition of goods. Essential for L/C compliance
Claused/dirty B/L: contains remarks about damage or deficiency. Will be rejected under an L/C
Straight B/L: non-negotiable, consigned to a named party. Cannot be transferred by endorsement
Order B/L: negotiable, made out "to order" or "to the order of [party]". Can be transferred by endorsement
Seaway bill: non-negotiable electronic or paper document. Faster than a B/L but provides no title function

Air Waybill (AWB)

The transport document for air freight, governed by the Montreal Convention (and its predecessor, the Warsaw Convention). The AWB is:

Non-negotiable: not a document of title - the consignee can collect the goods upon identification, without presenting the original AWB
Evidence of contract between shipper and carrier
Receipt for the goods
Typically issued as a Master AWB (carrier's document) and a House AWB (freight forwarder's document to the shipper)

CMR consignment note

The transport document for international road freight under the CMR Convention. The CMR note is:

Not a document of title (non-negotiable)
Evidence of contract of carriage and receipt for the goods
The sender can modify the instructions (right of disposal) until the goods are delivered to the consignee
Three originals: one for sender, one for carrier, one travels with the goods (for the consignee)
The e-CMR (electronic CMR) is increasingly adopted, having been ratified by most EU Member States under the e-CMR Protocol

CIM consignment note

The equivalent of the CMR for international rail transport, governed by the CIM Uniform Rules (part of COTIF). Similar characteristics: non-negotiable, evidences the contract of carriage, and serves as a receipt. The electronic CIM note is becoming standard.

Multimodal or combined transport document

Issued by a freight forwarder or MTO covering the entire door-to-door journey across multiple modes. The FIATA Multimodal Transport Bill of Lading (FBL) is the most widely recognised format and is accepted under L/Cs. It can be negotiable (like a B/L) when issued "to order".

Export packaging and marking

Proper packaging is essential to protect goods during the multiple handling stages of international transport. It must withstand stacking, moisture, vibration, and temperature variations. Packaging failures are a leading cause of cargo insurance claims.

Packaging requirements

Primary packaging: product packaging (consumer-facing)
Secondary packaging: shipping cartons, inner boxes
Tertiary packaging: palletisation, crating, containerisation

For sea and air freight, packaging must be resistant to moisture (especially for sea freight where containers experience condensation - known as "container rain"). Desiccant bags and moisture barrier films are commonly used.

ISPM 15 - wood packaging

International Standards for Phytosanitary Measures No. 15 (ISPM 15) requires all solid wood packaging material used in international trade (pallets, crates, dunnage) to be heat-treated or fumigated and marked with the ISPM 15 stamp. This prevents the international spread of wood pests. Non-compliance can result in shipment rejection at the destination port.

Cargo marking

Each package should be marked with:

Shipping marks (consignee's reference, destination, package number)
Handling symbols (ISO 780 - fragile, keep dry, this way up, stacking limits)
Weight and dimensions
Country of origin (often a legal requirement)
Hazardous goods markings and labels (if applicable, per IMDG Code for sea or IATA DGR for air)

Warehousing and free zones

Customs warehousing

Goods can be stored in a customs warehouse without payment of customs duties and import VAT for an unlimited period (under the Union Customs Code). Duties are only due when goods are released for free circulation. This is valuable for:

Importers who need to hold inventory but want to defer duty/VAT payment
Goods that will be re-exported (no duty is ever paid)
Goods awaiting allocation to different EU markets

Free zones

Free zones are enclosed areas within EU customs territory where non-Union goods can be introduced free of import duties, VAT, and commercial policy measures. Goods in free zones can be stored, processed, and re-exported. Major EU free zones include the Port of Hamburg free zone, Shannon (Ireland), Barcelona, and various zones in the Canary Islands and Azores.

Freight forwarder vs customs broker

These are distinct roles, though many companies offer both services:

Role	Function	Regulation
Freight forwarder	Arranges transport, consolidation, warehousing, and documentation on behalf of the shipper. Acts as the shipper's agent or as a principal (MTO).	Industry self-regulation (FIATA membership); some jurisdictions require licences
Customs broker	Prepares and files customs declarations on behalf of importers/exporters. Represents the declarant before customs authorities.	Must be authorised/registered with customs authorities. In the EU, any person may be a customs representative, but direct representation requires establishment in the EU

Tip: choose a freight forwarder with expertise in your specific trade lane, product type, and transport mode. A good freight forwarder will proactively advise on routing, carrier selection, consolidation opportunities, and regulatory requirements.

Cargo insurance

Why you need cargo insurance

The carrier's liability under international transport conventions is limited - often to a fraction of the goods' commercial value:

Convention	Carrier's maximum liability
Hague-Visby Rules (maritime)	2 SDR/kg or 666.67 SDR per package (whichever higher)
Montreal Convention (air)	22 SDR/kg
CMR Convention (road)	8.33 SDR/kg
CIM Convention (rail)	17 SDR/kg

For high-value goods, these limits may cover only a small fraction of the actual loss. Cargo insurance fills this gap.

Types of cargo insurance

Single shipment (voyage) policy: covers one specific shipment. Suitable for occasional shipments or unusually valuable consignments
Open policy (floating policy): provides ongoing coverage for all shipments over a period (typically 12 months). Each shipment is declared to the insurer. Suitable for regular traders with multiple shipments
Institute Cargo Clauses: the standard wordings used worldwide
- (A) All risks: covers all risks of physical loss or damage, subject to specific exclusions (war, strikes, inherent vice, delay)
- (B) Named perils - broad: covers fire, explosion, stranding, sinking, overturning, collision, discharge at port of distress, earthquake, lightning, washing overboard, general average
- (C) Named perils - basic: covers the most catastrophic perils only (fire, explosion, stranding, sinking, collision)

Insured value

Standard practice is to insure for CIF value + 10% (i.e., 110% of CIF). This covers the invoice value, freight, insurance premium, and an allowance for anticipated profit. For L/C transactions, 110% is the minimum required.

Supply chain optimisation

Visibility and tracking

Modern supply chains demand real-time visibility. Technologies enabling this include:

IoT sensors: track location (GPS), temperature, humidity, shock, and tilt throughout the journey
Carrier APIs: real-time container tracking from major shipping lines (Maersk, CMA CGM, MSC, Hapag-Lloyd all offer API-based tracking)
Port Community Systems: provide visibility on vessel arrivals, container discharge, and customs clearance status
TMS (Transport Management Systems): centralise booking, documentation, tracking, and cost management across modes

Sustainability

Supply chain sustainability is no longer optional. The EU's Corporate Sustainability Reporting Directive (CSRD) and the Carbon Border Adjustment Mechanism (CBAM) require companies to measure and report their Scope 3 emissions, including transport. Tools for reducing transport emissions include:

Modal shift from air and road to rail and maritime
Consolidation to improve load factors
Sustainable aviation fuel (SAF) for air freight - available at a premium
Alternative marine fuels (LNG, methanol, ammonia) and slow steaming
Near-sourcing to reduce transport distances
