Shipping Mark: Meaning, Format & Examples 2026
📅 Last updated: 2026-09-01 · ✍️ HowBridge Consolidation Editorial Team · 🛡️ Compiled from Customs announcements and current regulations
⚡ One-sentence answer: what is a shipping mark?
A shipping mark is the identification marking printed, written or pasted on a cargo's outer packaging so the goods can be identified and cleared through customs; the Chinese term is a phonetic loan of the English word “mark”. Under UNECE Recommendation No. 15, a standard shipping mark consists, in order, of four elements: the consignee's abbreviation, the reference number, the destination and the package number. In practice it is further split into the main mark and the side mark, for tallying, error prevention and customs checking.
📦 Taobao/1688 consolidation customers usually do NOT need to write their own shipping marks — the consolidator collects and forwards your parcels and automatically labels them with the warehouse address and your customer code; only commercial bulk shipments you arrange yourself require you to prepare correct shipping marks.
What Is a Shipping Mark?
A shipping mark (also written as a shipping mark; Shipping Mark in English) is a label printed, written, or pasted on the outer packaging of goods (cartons, wooden crates, pallets) to show the cargo information. It is a standard term in international trade and ocean shipping.
What a Shipping Mark Contains: Main Mark + Side Mark
A complete shipping mark usually has two parts: the "main mark" and the "side mark." The main mark is the primary identifier and is mandatory; the side mark is supplementary information that makes counting and sorting easier.
① Main Mark — mandatory and must be identifiable
| Main Mark Item | Description |
|---|---|
| Consignee / buyer mark | The consignee's or buyer's English abbreviation or graphic logo (the essential primary identifier) |
| Reference number | A traceable reference number such as the waybill, order, or invoice number |
| Destination port (place) | The name of the destination port or place, used for transshipment and break-bulk sorting |
| Number of pieces / batch number | The piece count or batch number of this shipment |
| Country of manufacture / origin | The country of manufacture or origin of the goods (relevant to the declared origin at customs) |
| (Optional) Consignee address and phone | In some cases the consignee's address and phone number are added for easy contact |
② Side Mark — supplementary information
| Side Mark Item | Description |
|---|---|
| Contract no. / license no. | The sales contract number or the import/export license number |
| Style no. / order no. | The product style number or the matching order number |
| Gross weight / net weight | Gross Weight and Net Weight |
| Volume (measurement) | The carton volume (CBM), used for space booking and freight calculation |
| Packing assortment | A note on the mix of items packed inside this box |
| Box serial number | Such as 1/10 or 2/10, showing which box this is out of the whole shipment |
| Quality grade | An indication of the quality or grade of the goods |
Which 4 elements make up the UNECE standard shipping mark?
Under paragraph 10 of Recommendation No. 15 of the United Nations Economic Commission for Europe (UNECE), Simpler Shipping Marks (fourth edition, ECE/TRADE/243, adopted November 1999), the standard shipping mark consists, in the following order, of these 4 elements, which should appear on both the packages and the documents; elements considered unnecessary may be omitted (for handling and storage pictograms, see ISO 780:2015 instead):
Consignee's or buyer's abbreviation
The primary mark identifying the cargo owner, usually the buyer company's English abbreviation.
Reference number
A traceable number such as the waybill, order, or invoice number.
Destination
The destination port or place name, used for transshipment routing.
Piece number
The package or carton sequence number (e.g. 1/25, meaning packages 1 to 25), which makes tallying easier.
UNECE's design is that “these 4 elements are the full set, from which you may still omit”, and it recommends showing only the gross weight in kilograms on the package. Adding net weight and measurement on the side mark is an industry-practice supplement. In practice, warning pictograms (fragile, this way up, keep dry) are still added according to the type of goods, the destination country's rules and the carriage terms.
Why Do Shipping Marks Matter?
① Identification and counting
A single shipment often has many boxes mixed together in the same vessel and container. It is the consignee abbreviation and box serial numbers (1/10, 2/10…) on the shipping mark that let the consignee and the warehouse quickly claim the cargo and count the quantity, so no box is missed or misidentified.
② Preventing shipping errors
With the destination port and consignee mark shown clearly on the outer carton, there is less risk of the goods being sent to the wrong place or handed to the wrong consignee during transshipment, consolidation, and devanning.
③ Faster customs clearance
- During inspection, customs checks the goods against the shipping mark and requires the marks on the outer carton to match those on the Packing List, the bill of lading, and the invoice.
- If the shipping marks on the documents (bill of lading / invoice / packing list) do not match the marks actually on the boxes, the inspection can easily stall — customs may ask for extra paperwork or open the boxes to inspect them, delaying release.
- A clear shipping mark and consistent documents make inspection smoother and clearance faster.
- Legal basis: the shipping mark (marks) is a declared item on the customs declaration. Under Articles 2 and 5 of Taiwan's Regulations for Correcting Declared Items on Import and Export Declarations, a declaration that does not match the facts must be corrected by applying to Customs with supporting documents (“marks and container numbers” is one of the items eligible for correction) — this is the origin of what the trade calls “filing supplementary documents” (Laws & Regulations Database).
④ Break-bulk and sorting at the destination port
After a full container (FCL) or a consolidated container (LCL) arrives at the port, the destination-port agent unpacks the container and sorts the goods by the shipping mark on the bill of lading, handing the right number of boxes to the correct consignee. The shipping mark is the basis for this sorting process.
Do Consolidation Customers Have to Write Their Own Shipping Marks?
This is the most common question from Taobao/1688 consolidation customers. The answer depends on whether you are a "regular B2C consolidation customer" or "shipping commercial bulk cargo yourself":
Regular Taobao consolidation customers: no need to write it yourself
- Consolidators (such as HowBridge) collect and forward on your behalf; when you place your order, the system automatically labels the parcel with the consolidation-warehouse address and your customer code.
- What you enter on Taobao/1688 is the consolidation-warehouse address plus your customer code; once the parcel reaches the warehouse, the consolidator identifies it and assigns it to your account.
- You do not need to hand-write a main mark or side mark on the carton yourself, and you do not have to deal with bill-of-lading shipping marks.
Commercial bulk / arranging your own ocean freight: correct shipping marks required
- If you are importing commercially, shipping a full container, or arranging ocean freight yourself, you need to prepare correct main and side marks according to the sales contract and the customs requirements.
- The shipping marks must match the packing list, invoice, and bill of lading, or the cargo can get held up during customs inspection.
- For this, HowBridge offers consolidation plus AEO customs brokerage and can handle shipping marks and customs documents on your behalf.
Not sure which one you are? HowBridge offers both Taobao consolidation and commercial bulk-import customs brokerage, with an AEO-certified partner customs broker helping to handle shipping marks, packing lists, and clearance documents. See our consolidation and customs plans.
Shipping Mark Examples (Main Mark / Side Mark)
Below is a typical commercial-export shipping mark example. Adjust the actual content to your own sales contract, consignee, and customs requirements.
How many sides of a carton need the shipping mark, and how do you mark a pallet?
Taiwanese law does not prescribe how many faces a shipping mark label must cover. The trade convention is at least two opposite faces of the carton (main mark on the front, side mark on one side); for palletised cargo, make it visible on all four upright faces so stacking cannot hide it.
Three practical points. Material: coated and woodfree paper labels are the norm and neither is waterproof — a splash is fine, soaking is not, so use synthetic stock or cover the label with clear tape on long ocean legs. Size: large enough to read while standing next to a stacked pallet; there is no legal size, A5 to A4 is common in practice. Consistency: the carton mark must match the packing list, invoice and bill of lading — under Articles 2 and 5 of Taiwan's Regulations Governing the Correction of Declared Items on Import and Export Declarations, a mismatch between the declared "marks and container numbers" and the facts requires supporting documents and a formal correction request. That is exactly why inspections turn into paperwork delays.
For pallets, note that the shipping mark and the IPPC stamp are two different things. The shipping mark is a commercial identifier — consignee abbreviation, reference number, destination, case numbers. The IPPC (ISPM 15) stamp is proof of phytosanitary treatment: under Taiwan's Plant Protection and Quarantine Act, solid wood pallets, crates and dunnage must first undergo heat treatment (HT) or methyl bromide fumigation (MB) and then carry a branded IPPC mark. Their placement differs too: the shipping mark goes on the carton or the outside of the stretch wrap, while the IPPC mark is branded into the timber itself and cannot be re-applied by the shipper. See our pallet specification and ISPM 15 guide.
Which risk category does a wrong shipping mark fall into? Tseng Wen-Jui, Ma Pi-Lien, Tsai Tsung-Che, Lin Hsin-I and Fang Ya-Hsin, "A Study on Risk Management of Import Cargo Customs Clearance and Transport" (Journal of National Kaohsiung Marine University, No. 27, March 2013, pp. 113-136) used a Delphi method, a questionnaire and expert interviews to identify 16 clearance and delivery risk factors and 21 risk management strategies, grouping risk sources into three classes: the cargo itself, documentary defects in the clearance process, and the inland transport leg. A mark that disagrees with the packing list sits squarely in the second class — and the study assigns the risk to the cargo owner. In other words, the shipper eats the cost of a mislabelled carton, and checking marks against documents beforehand is far cheaper than filing corrections later.
| Packaging type | Where to place the mark | Notes |
|---|---|---|
| Carton | Two opposite faces: front plus one side | Main mark on the front, side mark on the side |
| Wooden crate | Two faces or more; avoid nail lines and seals | Marker pen or stencil spray outlasts a sticker |
| Palletised cargo | Visible on all four upright faces, or on the stretch wrap | Solid wood pallets also need an IPPC brand — the two do not substitute |
| Loose or odd-shaped items | Largest flat face, at least two spots | Use a hang tag where there is no flat surface |
| Consolidated parcels | Nothing to mark yourself | The system applies the warehouse address and your customer code |
- Shortest way to write a shipping mark: consignee abbreviation → reference number (P/O or invoice) → destination port → case numbers (C/NO. 1-10) → country of origin. That is the five-line main mark; add the four-line side mark (G.W. / N.W. / MEAS / case sequence) when counting matters. Copy the example above directly.
- Keep label content in English and Arabic numerals. Where a graphic mark cannot be transmitted as text, declarations use a text code instead (for example IN DIA = inside a diamond); see the abbreviation table below.
- Keep stickers clear of tape seams and the box-cutter path, or the label is the first thing sliced open — and you lose a piece of evidence for returns and claims.
- The materials, sizes and face counts above are trade convention, not legal requirements. Taiwanese law only requires the mark to agree with the declaration and the documents; the buyer's instructions and the carrier's rules still govern.
Shipping Mark Abbreviations at a Glance (C/NO., G.W., MEAS, N/M, IN DIA)
The table below lists the shipping-mark abbreviations you will most often see on customs declarations, bills of lading and outer cartons. “Marks & Nos.” is the official name of the shipping-mark field on the bill of lading and the declaration.
| Abbreviation | Full form | Meaning |
|---|---|---|
| MARKS | Marks | Shipping mark / marks. Customs Administration, Ministry of Finance clearance manual: “Marks & Nos.” means the marks on the goods (shipping mark, MARKS) and the case number (CASE NO.). |
| MARKS & NOS. | Marks and Numbers | Marks and numbers — the official name of the shipping-mark field on the bill of lading and the customs declaration. |
| C/NO. | Case Number | Case number / carton sequence number (e.g. C/NO. 1/10 means carton 1 of 10). |
| G.W. | Gross Weight | Gross weight (including packaging). |
| N.W. | Net Weight | Net weight (excluding packaging). |
| MEAS | Measurement | Measurement (volume, usually stated in CBM, cubic metres). |
| N/M | No Mark | Annotation for “no shipping mark” (also written N.M.; for consolidated import cargo shown as N/M, re-marking must be applied for first). |
| IN DIA | in Diamond | “Inside a diamond”. When a shipping-mark graphic cannot be transmitted as text, the declaration writes “IN + shape code”: IN DIA means the mark sits inside a diamond, IN TRIANGLE inside a triangle. Common shape codes used by the Customs Administration: circle CIR., square SQ., rectangle REC., triangle TRI., diamond DIA., oval OVAL, star STAR. |
The above is an illustrative format (C/NO. = Case Number, G.W. = Gross Weight, N.W. = Net Weight, MEAS = Measurement). For an actual export, always follow the content of your own contract, invoice, and packing list.
International Standards and Source Documents
Outer-carton marks, packing-list fields, dangerous-goods labelling and destination-country requirements are governed by different rules and must be checked separately for each cargo type and mode of transport.
