International Vehicle Shipping Glossary: Bill of Lading, HS Codes, Dim Weight & Letter of Credit (2026)

📅 2026-09-28 ⏱ 10 min read ✍ UZCAN Expert Team

International vehicle shipping has its own vocabulary. Quotes, customs brokers and shipping lines use terms like Bill of Lading, HS code, dimensional weight and Letter of Credit — often without explaining them. This glossary explains each term in plain language, corrects outdated definitions still found online, and shows where each one matters when you ship a car, motorcycle or parts.

1. Quick-reference table

TermWhat it isWhy it matters for your vehicle
Bill of Lading (B/L)Carrier's document: contract of carriage, receipt and — in negotiable form — document of titleLists your vehicle by VIN and controls who collects it at destination
HS codeInternational 6-digit product classification used by customsSets the duty rate — e.g. 8703 for cars vs. 9705 for qualifying collector cars
Dimensional weightA "weight" calculated from size, billed when higher than actual weightApplies to parts, boxes and air cargo — not a car in its own container slot
Letter of Credit (LC)A bank's undertaking to pay a seller against specified documentsUsed when buying a vehicle from a business abroad

2. Bill of Lading (B/L or BOL)

A Bill of Lading is the document a carrier issues when it receives cargo. B/L is the usual ocean-freight abbreviation and BOL is common in North American trucking — they mean the same thing. It does three jobs:

  • Contract of carriage: the terms under which the carrier moves the goods
  • Receipt: confirms what was loaded, in what condition and in which container
  • Document of title: only in negotiable ("to order") form — the holder of the endorsed original can claim the cargo

Not every B/L is a document of title:

TypeHow release worksTypical use
Negotiable ("to order") B/LOriginals must be surrendered; can be endorsed to a new ownerCommercial sales, especially with a Letter of Credit
Straight B/LNames a specific consignee; not transferableTrusted buyer–seller relationships
Sea waybillNo originals; named consignee collects on identificationPrivate shipments and relocations
Telex / express releaseOriginals surrendered at origin, release sent electronicallyAvoids courier delays

For a vehicle, check that the B/L shows the correct VIN, make, model and year, container and seal numbers and consignee. A mismatch between B/L and title is a common cause of holds. You may also see a Master B/L (carrier to forwarder) and a House B/L (forwarder to you) for the same voyage.

3. HS codes (Harmonized System)

The Harmonized System is the product classification customs authorities in more than 200 economies use to apply duty rates and collect statistics. It is maintained by the World Customs Organization (WCO) in Brussels — older glossaries still use its pre-1994 name, the "Customs Co-operation Council".

Structure (HS 2022 edition)

  • 21 sections in Roman numerals — Section XVII covers vehicles, aircraft and vessels
  • 97 chapters in use, with Chapter 77 reserved; Chapters 98 and 99 are left for national provisions
  • 1,228 headings (4-digit) and 5,612 subheadings (6-digit)
  • Revised every five years — HS 2027 is scheduled to take effect on 1 January 2027
Country / regionNational scheduleDigits
United StatesHTSUS (duty at 8 digits, statistics at 10); exports use Schedule B10
CanadaCustoms Tariff (CBSA)10
European UnionCombined Nomenclature (8) and TARIC (10)8–10
TurkeyTurkish Customs Tariff (GTİP)12

Note: older sources still call the U.S. schedule "TSUSA" — it was replaced by the HTSUS in 1989.

HS codes for vehicles

  • 8703 — passenger cars, SUVs and vans
  • 8711 — motorcycles and mopeds
  • 8704 — goods vehicles such as pickups and trucks
  • 9705 — collectors' pieces; in the EU this can include cars 30+ years old, original and no longer in production. See our classic car restoration in Poland guide

Customs, not the shipper, decides the classification — a wrong code can mean penalties or a higher duty bill.

4. Dimensional ("dim") weight

Dimensional weight (volumetric weight) exists because a large, light package uses more space than its scale weight suggests. Carriers calculate a weight from the dimensions and bill whichever is greater — the chargeable weight.

  • Imperial: L × W × H (inches) ÷ divisor = pounds
  • Metric: L × W × H (cm) ÷ divisor = kilograms

Older guides quote divisors of 166 (international) and 194 (domestic) — outdated for most express services. Today 139 in³/lb (≈ 5,000 cm³/kg) is the most common divisor for major express carriers; some economy services still use 166 (≈ 6,000 cm³/kg), and air cargo usually works on 6,000 cm³/kg. Always check your carrier's current rate guide.

Worked example: a 30 × 24 × 22 in box (15,840 in³)

DivisorCalculationDimensional weight
139 (most express services)15,840 ÷ 139 = 113.96114 lb
166 (economy / legacy)15,840 ÷ 166 = 95.4296 lb

If the box weighs 60 lb, you pay for 114 lb (or 96 lb). Carriers also round each dimension up before calculating.

Does dim weight apply to shipping a car?

Not in the same way. A car by ocean container is priced per container slot; RoRo is priced per vehicle or by volume. Ocean cargo such as a pallet of parts is charged on "weight or measure" (1 m³ is usually treated as 1,000 kg). Dim weight matters most for parts, wheels, boxes and air freight — see air freight vehicle shipping.

5. Letter of Credit (LC)

A Letter of Credit is a bank's written undertaking, issued on the buyer's instructions, to pay the seller once documents matching the LC's terms are presented — typically an invoice, a Bill of Lading and insurance documents, within a deadline. Banks pay against documents, not goods. Most LCs follow the ICC's UCP 600 rules.

  • Irrevocable: cannot be changed without everyone's agreement — the modern default
  • Confirmed: a second bank adds its own guarantee
  • Sight vs. deferred: payment on presentation or at a set later date
  • Standby: a guarantee drawn only if the buyer fails to pay

Do I need a Letter of Credit to ship my vehicle?

Usually no. Shipping your own vehicle involves no sale, so there is nothing for an LC to secure. LCs matter when you buy a vehicle from a business abroad and want the seller paid only once the car has shipped — usually against a negotiable Bill of Lading. For smaller private purchases, regulated escrow is often simpler.

6. More terms on a vehicle shipment

Transport and pricing

  • RoRo: the vehicle is driven onto a car-carrier ship — see RoRo shipping
  • FCL / LCL: full container (yours alone) vs. shared container
  • Consolidation: several vehicles sharing one container or truck
  • CBM: cubic metre, the unit of volume in ocean freight

Insurance and handover

Summary: 5 things to remember

  1. A Bill of Lading is a document of title only in negotiable form — a sea waybill is often simpler for private vehicles
  2. The HS code sets your duty rate; the first 6 digits are global, the rest national
  3. Most express carriers now use a dim-weight divisor of 139 (5,000 metric), not 166/194
  4. Dim weight applies to parts and air cargo, not a car in its own container slot
  5. You rarely need a Letter of Credit unless buying from a business abroad

Frequently Asked Questions

The carrier's document for your shipment: contract of carriage, receipt showing your vehicle (by VIN) was loaded and — in negotiable form — a document of title controlling who collects the car. Many private shipments use a sea waybill instead, which releases the car to the named consignee without original papers.
A negotiable B/L must be surrendered in original and can be endorsed to a new owner. A sea waybill is not a document of title: the named consignee identifies themselves to collect the vehicle. Waybills are faster and suit relocations and restoration shipments where there is no sale.
Most passenger cars fall under heading 8703, motorcycles under 8711 and pickups/trucks under 8704. In the EU a qualifying collector car — generally 30+ years old, original and no longer in production — can fall under 9705, usually with no import duty and reduced VAT. Customs makes the final decision.
HS 2022 has 21 sections and 97 chapters in use (Chapter 77 reserved), with 1,228 headings and 5,612 subheadings. The WCO revises it every five years; HS 2027 is scheduled for 1 January 2027.
Multiply length × width × height in inches and divide by the carrier's divisor — most major express carriers use 139 (or 5,000 in cm/kg); some economy services use 166. You pay on the higher of actual and dimensional weight. A 30 × 24 × 22 in box gives 114 lb at 139.
Not for ocean shipping — a car in a container is priced per slot and RoRo per vehicle or volume. Dim weight matters for parts, boxes and air freight.
Usually not. Shipping your own vehicle involves no sale. LCs are used when buying a vehicle from a business abroad, so the bank pays only against shipping documents such as a negotiable Bill of Lading.
On our North American routes UZCAN handles ocean freight, insurance, condition documentation and tracking. Customs declarations, classification, duties and taxes are handled by you or your licensed customs broker; we are happy to coordinate.
