Cargo Marking in Logistics: What Must Be on the Packaging for International Transportation

Imagine the airport lost your suitcase — without a luggage tag. That is exactly how a logistics specialist feels when a container arrives at the warehouse without readable markings: the cargo is there, but what to do with it is unclear. Customs will not accept it, the freight forwarder cannot locate it, the warehouse keeper cannot sort it. Proper marking is not bureaucracy for its own sake. It is the cargo’s digital passport, working at every stage: from the sender’s warehouse to the last mile of delivery.

What Cargo Marking Is and Why It Is Needed

Cargo marking is the set of inscriptions, signs, symbols, and machine-readable codes applied to packaging, a container, or a transport unit, containing all the information necessary for the identification, transportation, storage, and customs clearance of goods.
Marking performs several functions simultaneously. Identification: unambiguously establishes what the cargo is, who it belongs to, and where it is going. Informational: communicates the contents, weight, dimensions, and handling conditions. Protective: warns of hazards, fragility, orientation requirements, and temperature conditions. Control: enables the cargo to be scanned at every stage of the supply chain and tracked in real time.

The key principle:
Cargo without marking is just a box. Customs will not accept a declaration if the data on the packaging differs from the documents. The carrier bears no responsibility for unmarked cargo. The insurer will deny a claim if damage occurred due to incorrect marking of storage conditions.

Types of Marking: What Goes Where

Cargo marking is divided into several types depending on its purpose. In practice, all types are applied simultaneously — each for its own audience in the supply chain.

Product (Consumer) Marking

Applied to the primary product packaging by the manufacturer. Contains the product name, brand, article number, composition, country of manufacture, production date, and expiry date (for food and pharmaceutical goods). For import into Russia, labeling in Russian is mandatory in accordance with the requirements of the Customs Union technical regulations (TR CU). For certain categories (electronics, clothing, footwear, dairy products), a Chestny Znak system code — Data Matrix — is required.

Transport Marking

Applied to the outer transport packaging (boxes, pallets, crates) and intended for all participants in the logistics chain — from the loader to the customs inspector. In Russia, it is regulated by GOST 14192-96 “Cargo Marking.” It includes three groups of data:

  • Primary inscriptions: name and address of the consignee, name of the consignor, destination, sequential unit number and total number of units in the shipment
  • Additional inscriptions: gross and net weight of each unit, overall dimensions (length × width × height), country of origin
  • Informational inscriptions: transport document number (bill of lading, CMR, consignment note), contract or order number

Special Marking

Includes handling symbols, hazard labels, and environmental marks. Handling symbols under GOST 14192-96 (and their ISO 780 equivalents) are pictograms indicating how to handle the cargo: “This Way Up,” “Fragile,” “Keep Dry,” “Do Not Roll,” “Sling Here,” “Keep Away from Heat,” “Keep Away from Cold,” “Temperature Limitations,” and others. Hazard labels under ADR/GOST for hazardous goods are covered separately in Section 5.

Machine-Readable Marking

Barcodes and two-dimensional codes are an essential element of modern logistics. Linear barcode EAN-13 / UPC-A — for retail identification at the checkout. GS1-128 barcode (Code 128) — a transport label containing batch data, expiry date, and serial number in the GS1 standard. Two-dimensional QR / Data Matrix code — for the Chestny Znak labeling system, pharmaceuticals, and electronics. RFID tag — for automated warehouses and terminals without manual scanning.

Marking of Sea Containers: ISO 6346 Standard

A sea container is a standardized transport unit, and its marking is regulated by the international standard ISO 6346:2022 (4th edition, last revised 2022–2023). The standard is mandatory for all shipping lines and port terminals worldwide. The current edition expanded codes for new container types (specialized transport for lithium batteries, LNG) and added requirements for digital identification (RFID, AEI).

Unique Container Number (BIC Code)

Every sea container has a unique 11-character identifier in the format AAAA NNNNNN C, where:

  • AAAA — four-letter owner code (first three letters — company code, fourth — always U for freight containers, J for detachable equipment, Z for trailers)
  • NNNNNN — six-digit serial number
  • C — check digit (calculated by algorithm, enabling automatic error detection when entering the number)

Example: MSCU 1234567 — a container belonging to MSC (Mediterranean Shipping Company), number 123456, check digit 7. The number is applied to all four sides of the container and to the roof (for aerial reading at the port).

Container Technical Data on the Doors

Parameter What it means
Container Type (Type/Size Code) Four-character code per ISO 6346: size (20’/40’/45′) and type (GP — standard, RF — refrigerated, OT — open top, TK — tank, etc.)
Maximum Gross Weight Maximum permissible weight of the container with cargo — typically 20,800–30,480 kg for 20′ and 32,500 kg for 40′
Tare Weight Own weight of the empty container: from 1,800 kg (20′ standard), up to 3,800 kg (40′ standard), up to 4,200–4,800 kg (40′ HC Reefer — due to the refrigeration unit and insulated walls)
Max Payload Maximum permissible cargo weight = gross minus tare
Cubic Capacity Usable volume in m³: ~28–30 m³ for 20′, ~56–60 m³ for 40′ standard, up to 67 m³ for 40′ HC
CSC Certification Plate Convention for Safe Containers plate with the date of the container’s next technical inspection

Important for overloading:
The gross weight of the cargo must strictly correspond to the VGM (Verified Gross Mass) as required by the SOLAS amendment in force since July 1, 2016. Without a VGM certificate, the container cannot be loaded onto a vessel. Responsibility for providing the VGM lies with the shipper.

Transport Label: What Must Be on Every Cargo Unit

A transport label (shipping label) is a structured information carrier applied to every cargo unit (box, pallet, crate) that allows it to be identified at any point along the route without opening it.

Mandatory elements of a transport label

  1. Consignee: full name, warehouse or distribution center address, contact phone number
  2. Shipper/Consignor: name and address
  3. Description of contents: product name, article number, number of units in the package
  4. Net and gross weight of the cargo unit (kg)
  5. Dimensions: length × width × height in cm or mm
  6. Unit number in the shipment: “1/20,” “2/20,” etc. — sequential number and total number of units
  7. Transport document number: bill of lading (B/L No.), CMR, AWB — for identification in the carrier’s system
  8. Country of Origin — for customs control
  9. Barcode or QR code with machine-readable duplication of all key data

GS1 transport label standard:
The international transport label standard is GS1-128 (Logistics Label). It contains Application Identifiers (AI): AI 00 — Serial Shipping Container Code (SSCC), AI 02 — GTIN of the contents, AI 37 — quantity, AI 10 — batch number, AI 17 — expiry date. WMS (warehouse management system) systems of major retailers and distributors only accept GS1-compatible labels. Verify the recipient’s requirements before dispatch.

Marking of Hazardous Goods: Labels, Placards, and Documents

The marking of hazardous goods is the most strictly regulated area. Violation of requirements results in refusal of transport, fines, and criminal liability in the event of an accident.

Diamond-Shaped Hazard Labels

Each class of hazardous goods under the UN classification has its own diamond-shaped label (100 × 100 mm on packaging, 250 × 250 mm on a container). The classification under ADR / IMDG Code includes 9 classes:

Class Type of Hazard Examples of Goods
Class 1 Explosive substances and articles Fireworks, ammunition, pyrotechnics
Class 2 Gases (compressed, liquefied, dissolved) CO₂ cylinders, aerosols, refrigerants
Class 3 Flammable liquids Paints, varnishes, solvents, alcohols
Class 4 Flammable solids Matches, metal powders, sulfur
Class 5 Oxidizing substances and organic peroxides Hydrogen peroxide, nitrates, fertilizers
Class 6 Toxic and infectious substances Pesticides, medical waste
Class 7 Radioactive materials Medical isotopes, industrial sources
Class 8 Corrosive substances Acids, alkalis, batteries with electrolyte
Class 9 Miscellaneous dangerous substances Lithium batteries, dry ice, magnetized objects

 

ADR Orange Placards

For road transport of hazardous goods, rectangular orange placards (400 × 300 mm) must be affixed to the front and rear of the vehicle. They indicate: upper section — emergency action code (Kemler code, 2–3 digits, indicating the type of hazard and measures to be taken); lower section — UN number of the substance (4 digits, assigned by the UN to each hazardous substance).

Example: the placard “33/1203” means Kemler code 33 (flammable liquid) and UN 1203 (motor gasoline).

Marking of Lithium Batteries (Class 9)

Lithium batteries and accumulators are one of the most problematic cargo types in modern logistics. Special requirements apply to them: a diamond-shaped “Lithium Battery” label with a battery symbol inside, indication of type (Li-Ion or Li-Metal), power in Wh (watt-hours), and UN number (UN 3480 — Li-Ion batteries standalone, UN 3481 — Li-Ion in equipment, UN 3090/3091 — metal batteries). For passenger air transport, the following rules apply under IATA DGR 2026 and ICAO Doc 9284: batteries up to 100 Wh — in carry-on baggage without prior approval; 100–160 Wh — in carry-on baggage with airline approval, maximum 2 units; over 160 Wh — prohibited for passengers. Spare batteries may not be checked in as registered baggage. Separate conditions apply for cargo air transport — verify with the air carrier.

Marking of Refrigerated Cargo

Cargo requiring temperature control has additional marking requirements that supplement the standard transport label.

Marking element Content and requirements
Temperature regime “KEEP FROZEN −18°C” / “KEEP REFRIGERATED +2…+8°C” — indicated on each cargo unit and on the container door. Must match the data in the transport document and insurance policy.
“Keep Away from Heat” symbol (GOST 14192) Pictogram with a thermometer and upward arrow — mandatory for all temperature-sensitive cargo
Logger data The accompanying document specifies the serial number of the temperature logger placed inside the container and the permissible deviation range
Sanitary marking For food cargo — the number of the veterinary or phytosanitary certificate and the facility’s accreditation number in the Rosselkhoznadzor registry
Expiry date on transport packaging Best Before / Use By — duplicated on the outer packaging for verification upon acceptance at the recipient’s warehouse

A typical mistake:
A discrepancy between the temperature regime indicated on the packaging and the data in the bill of lading / CMR consignment note is one of the main grounds for denial of an insurance claim in the event of refrigerated cargo spoilage. The marking, transport document, and insurance policy must all specify the same regime.

Marking Requirements in Different Countries: Key Differences

Cargo marking rules vary depending on the destination country, mode of transport, and product category. The essence is the same everywhere — clearly legible, with a machine-readable code — but specific requirements differ.

Country / bloc Key requirements Specifics
Russia / EAEU GOST 14192-96, TR CU, Chestny Znak (Data Matrix) for applicable categories Marking in Russian is mandatory for goods in retail circulation. Transport marking — in the language of the documents
China (export) GB standards, marking in Chinese and English, HS code indication Compliance with Chinese packaging standards is mandatory for passing Chinese export customs. For certain goods (electronics, household appliances) imported into China, CCC (China Compulsory Certification) marking is required
EU (transit / re-export) CE Directive, CLP regulation for hazardous substances, GS1 standard CE marking is mandatory for electrical equipment, toys, and medical devices. Absence of CE — import prohibited
USA FCC ID for electronics, FDA registration for food products, DOT for hazardous goods “Made in China” / “Made in Vietnam” etc. marking mandatory on each individual unit
Sea freight (all countries) ISO 6346 for containers, SOLAS VGM, IMDG Code for hazardous goods VGM mandatory since 2016 for all containers. Non-compliance = refusal to load onto vessel

Common Cargo Marking Mistakes

Most delays at customs and during acceptance are linked to the same marking violations. Here are the most frequent ones:

  1. Discrepancy between label data and documents. If the box states “500 kg” but the invoice shows “480 kg,” customs will order weighing and inspection. Delay — 2–5 business days.
  2. Unreadable or damaged barcode. The scanner at the customs terminal or warehouse cannot read the code — the cargo is sent for manual processing. A common cause: applying the code to a glossy surface or across packaging seams.
  3. Absence of marking in the destination country’s language. In Russia, Russian-language marking of consumer goods is mandatory. Its absence results in a ban on release into circulation and return of the shipment.
  4. Incorrect or missing hazard labels. For hazardous goods — grounds for refusal of transport and an administrative fine. A common situation: the UN number is not indicated, or the hazard class does not match the actual contents.
  5. Absence of VGM for a sea container. Without confirmed gross mass, the shipping line will refuse to load. Replacing the document after the fact means loss of the slot and additional port storage costs.
  6. Refrigerated cargo marking without temperature regime indication. If discovered at border control — detention for verification of transport conditions; if non-compliant — import ban.
  7. Marking not applied to all cargo units. Absence of the unit number (“5/20,” etc.) on each box is grounds for a full recount of the entire shipment at customs.
