Shipping has its own language, and not knowing it is how SME owners lose money on cross-border deals. This glossary defines more than 50 of the terms that decide cost, control, and clearance in international trade — from Incoterms and bill of lading to HS codes, demurrage, and letters of credit. Each definition is written plainly for business owners, not logistics professionals, and grouped so you can learn one area at a time. Where a term deserves a full guide, it links to one. Keep this open beside any freight quote, and the jargon stops being a barrier between you and a fair price.
Key Takeaway. Master the vocabulary and you control the conversation. These 50+ terms cover the six areas that move money in shipping: trade terms, documents, customs, modes and cargo, payment, and the players. Learn the words, and a freight quote stops reading like a foreign language — you start spotting what it leaves out.
Trade Terms (Incoterms)
Incoterms are the backbone of any cross-border deal: they decide who pays for each leg and where risk passes from seller to buyer. Agree the wrong one and you can inherit a tax bill you never priced. These are the terms you will see most often on a quote or sales contract.
Incoterms — the 11 standard ICC rules that split cost, risk, and duty between buyer and seller; the 2020 edition is current in 2026.
EXW (Ex Works) — the buyer collects the goods at the seller’s premises and carries nearly all cost and risk from that point.
FCA (Free Carrier) — the seller delivers the goods, cleared for export, to a carrier the buyer names; risk passes there.
FAS (Free Alongside Ship) — a sea-only term where the seller delivers the goods alongside the vessel at the port of loading.
FOB (Free On Board) — a sea-only term where risk passes to the buyer once goods are loaded on board the vessel.
CFR (Cost and Freight) — a sea-only term where the seller pays freight to the destination port but does not insure the goods.
CIF (Cost, Insurance, Freight) — a sea-only term where the seller pays freight and minimum insurance to the destination port.
CPT (Carriage Paid To) — an any-mode term where the seller pays carriage to a named destination; risk passes when goods reach the first carrier.
CIP (Carriage and Insurance Paid To) — like CPT, but the seller also buys higher-level insurance to the named destination.
DAP (Delivered At Place) — the seller delivers to the destination, but the buyer clears import and pays duty and tax.
DPU (Delivered at Place Unloaded) — the seller delivers and unloads at the named place; the buyer still clears import.
DDP (Delivered Duty Paid) — the seller pays everything, including import clearance, duty, and destination GST — the heaviest seller obligation.
Shipping Documents
Documents are where control and proof live. Customs reads them, banks rely on them, and a mismatch between them is one of the most common reasons cargo is held. Learn what each one does before you sign it.
Bill of Lading (B/L) — the carrier’s receipt, contract of carriage, and — in original form — the document of title that releases the cargo.
Original B/L — a negotiable bill of lading; the consignee must present an original to collect the goods.
Telex Release — an instruction that releases cargo at destination after the originals are surrendered at origin.
Seaway Bill — a non-negotiable bill with no originals; goods release to the named consignee without document surrender.
Commercial Invoice — the seller’s bill to the buyer; customs uses it to assess value, duty, and tax.
Packing List — an itemised list of the shipment’s contents, weights, and dimensions that must match the invoice.
Certificate of Origin — a document proving where goods were made, often required to claim preferential duty.
Form D — the ASEAN (ATIGA) Certificate of Origin that lets a buyer claim preferential or zero import duty.
Customs and Compliance
Customs is rarely random; it rewards owners who prepare. These terms cover how goods are classified, taxed, and released — and the charges that pile up when a shipment is held. Getting them right is the difference between a smooth clearance and a costly delay.
HS Code — the standardised product code that sets duty, tax, and permit requirements; the first six digits are global.
AHTN — the ASEAN Harmonised Tariff Nomenclature, which extends the HS code to eight digits for ASEAN countries.
Customs Clearance — the official approval that lets cargo legally leave a port or checkpoint once duty, tax, and permits are settled.
Import Duty — a tax on imported goods set by their HS code; Singapore charges it only on a few categories such as liquor and tobacco.
GST — Goods and Services Tax; Singapore charges 9% on the CIF value of imports (Singapore Customs).
CIF Value — the customs value used to calculate tax: cost of goods plus insurance plus freight.
De Minimis — a value threshold below which imports may be exempt from duty or tax; it varies by country and mode.
LARTAS — Indonesia’s list of restricted goods that need a permit before they can be imported.
Red Lane / Green Lane — customs inspection channels; green clears on documents, red triggers a physical inspection.
Bonded Warehouse — a secured facility where imported goods are stored with duty and tax deferred until they are released.
Demurrage — a charge for keeping a container at the port beyond the free storage days.
Detention — a charge for keeping a carrier’s container outside the port (at your yard) beyond the free days.
Free Time — the grace period before demurrage or detention charges begin to accrue.
Modes and Cargo Types
The mode you ship by — and the way your cargo is packed and measured — drives both cost and transit time. These terms describe the choices a freight forwarder helps you weigh on every shipment.
Sea Freight — cargo moved by ocean vessel; the cheapest mode per unit for most volume cargo.
Air Freight — cargo moved by aircraft; faster and pricier, suited to urgent or high-value goods.
FCL (Full Container Load) — a shipment that fills a whole container, booked exclusively for one consignee.
LCL (Less than Container Load) — a shipment too small for a full container, consolidated with other cargo.
Consolidation — combining several small shipments into one container to lower the per-unit freight cost.
Transhipment — transferring cargo from one vessel or vehicle to another at an intermediate port en route to the destination.
NVOCC — a Non-Vessel Operating Common Carrier; a forwarder that issues its own bill of lading without owning ships.
Out-of-Gauge Cargo — freight too large for a standard container, shipped on flat racks, open tops, or as break bulk.
Break Bulk — cargo shipped loose or on pallets rather than in a container, common for oversized project cargo.
CBM (Cubic Metre) — the volume measure for cargo; sea freight is often priced by CBM or by weight, whichever is greater.
Chargeable Weight — the figure used to price a shipment: the greater of actual weight and volumetric weight.
Dangerous Goods — cargo classed as hazardous (one of nine UN classes) that needs special declaration and packaging.
Parcel Forwarding — a service that receives your overseas purchases and ships them on, handling customs and GST.
Payment and Finance
Payment terms decide who carries the risk of not being paid — the other half of every deal your Incoterm sets up. These terms range from bank-backed security to trust-based credit, and the right one depends on how well you know your counterpart.
Letter of Credit (LC) — a bank-backed payment guarantee issued before shipment that protects the exporter.
Open Account — a term where goods ship first and the buyer pays later, which favours the buyer’s cash flow.
Documentary Collection — banks exchange shipping documents for payment, but without a bank guarantee, governed by URC 522.
UCP 600 — the ICC rulebook that governs letters of credit worldwide.
Landed Cost — the all-in cost of getting goods to your door: product, freight, insurance, duty, tax, and handling.
The Players
Owners often confuse the parties in a shipment, and the confusion costs money, because each one only answers for its own slice. Knowing who does what tells you who to call when something goes wrong.
Freight Forwarder — the company that arranges and manages your shipment end to end without necessarily owning the transport.
Carrier — the company that owns and operates the vessel, aircraft, or lorry that physically moves the cargo.
Customs Broker — a licensed agent who files customs declarations and clears goods, and nothing more.
Shipper — the party sending the goods, usually the exporter or seller.
Consignee — the party receiving the goods, usually the importer or buyer named on the bill of lading.
Frequently Asked Questions
What shipping terms should an SME owner learn first?
Start with Incoterms, the bill of lading, and HS codes. Incoterms decide who pays; the bill of lading controls the cargo; the HS code sets your duty and tax. These three terms underpin almost every other word in this glossary, and getting them right prevents the most expensive shipping mistakes.
What is the difference between demurrage and detention?
Demurrage is charged when a container sits at the port beyond the free storage days. Detention is charged when you keep the carrier’s container outside the port — at your warehouse — beyond the free days. Both are time-based penalties that add up fast, so plan collection and return carefully.
Is a bill of lading the same as an invoice?
No. The commercial invoice is the seller’s bill to the buyer and states the value for customs. The bill of lading is the carrier’s document that acts as receipt, contract, and — in original form — title to the goods. They serve different purposes and must agree with each other.
What does CIF value mean for my import tax?
CIF value is the customs value used to calculate import tax: cost of goods plus insurance plus freight. Singapore charges 9% GST on this CIF value, not on the goods alone (Singapore Customs). So a cheaper freight rate slightly lowers your tax base as well as your shipping bill.
Turn the Vocabulary Into Judgement
Knowing the words is step one; using them with confidence is where the money is. Work through the practical shipping guide to turn these definitions into judgement, and you will read any quote and brief any forwarder as an equal.
