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.

HowBridge provides China-to-Taiwan logistics. The China warehouse identifies inbound parcels by customer code; commercial cargo marks are checked against packing lists, invoices, transport documents and carrier requirements. A shipping mark does not replace legally required cargo details.

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.

Word origin: The Chinese character mark used in the trade term is a phonetic loan of the English word “mark”, read mà — the Ministry of Education's Dictionary of Chinese Character Variants (standard character B00413) glosses it precisely as “a phonetic rendering of the English word mark”. It simply means “a mark or sign”.
Written forms: In Chinese the term has two interchangeable spellings that are used synonymously across the industry; both mean "shipping mark," and formal documents and trade textbooks tend to prefer one of them.
Format: It can be printed, written with a permanent marker, or applied as a pre-printed adhesive label, placed where it is easy to see on the outer carton (usually the front and the side of the box).
Purpose: It lets goods be identified quickly at every stage — transport, transshipment, customs declaration, and devanning — and ties them to the shipping documents (bill of lading, invoice, packing list).
Common variants and misspellings: Formal documents usually use one spelling and everyday or online writing another, but the two are identical; because the characters sound alike, the term is also frequently mistyped, yet every version still refers to the same Shipping Mark. In English it is the Shipping Mark (also called the transport marking or shipping marking).

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 ItemDescription
Consignee / buyer markThe consignee's or buyer's English abbreviation or graphic logo (the essential primary identifier)
Reference numberA 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 numberThe piece count or batch number of this shipment
Country of manufacture / originThe country of manufacture or origin of the goods (relevant to the declared origin at customs)
(Optional) Consignee address and phoneIn some cases the consignee's address and phone number are added for easy contact

② Side Mark — supplementary information

Side Mark ItemDescription
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 weightGross Weight and Net Weight
Volume (measurement)The carton volume (CBM), used for space booking and freight calculation
Packing assortmentA note on the mix of items packed inside this box
Box serial numberSuch as 1/10 or 2/10, showing which box this is out of the whole shipment
Quality gradeAn indication of the quality or grade of the goods
💡 Quick tip: The main mark decides "whose cargo this is and where it is going"; the side mark decides "how easy it is to count and sort into boxes." Before export, always make sure the shipping mark matches the Packing List and the Invoice.

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.

Main mark exampleABC CO.P/O: 20260625-001KEELUNG, TAIWANC/NO. 1-10MADE IN CHINA
Side mark exampleG.W.: 18.5 KGSN.W.: 16.0 KGSMEAS: 0.045 CBMC/NO. 1/10
What is N/M? N/M is the annotation for No Mark (also written N.M.). The clearance manual of the Customs Administration, Ministry of Finance provides that an export declaration “must state N/M if there is no shipping mark”; and when the bill of lading for consolidated import cargo is marked N/M, re-marking must first be applied for at the inspection and warehousing unit handling clearance before it can be transmitted on the declaration. For consolidation and LCL cargo it is therefore still advisable to show at least the consignee's abbreviation and the carton sequence number.

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 typeWhere to place the markNotes
CartonTwo opposite faces: front plus one sideMain mark on the front, side mark on the side
Wooden crateTwo faces or more; avoid nail lines and sealsMarker pen or stencil spray outlasts a sticker
Palletised cargoVisible on all four upright faces, or on the stretch wrapSolid wood pallets also need an IPPC brand — the two do not substitute
Loose or odd-shaped itemsLargest flat face, at least two spotsUse a hang tag where there is no flat surface
Consolidated parcelsNothing to mark yourselfThe 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.

AbbreviationFull formMeaning
MARKSMarksShipping 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 NumbersMarks and numbers — the official name of the shipping-mark field on the bill of lading and the customs declaration.
C/NO.Case NumberCase number / carton sequence number (e.g. C/NO. 1/10 means carton 1 of 10).
G.W.Gross WeightGross weight (including packaging).
N.W.Net WeightNet weight (excluding packaging).
MEASMeasurementMeasurement (volume, usually stated in CBM, cubic metres).
N/MNo MarkAnnotation for “no shipping mark” (also written N.M.; for consolidated import cargo shown as N/M, re-marking must be applied for first).
IN DIAin 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.

Frequently Asked Questions (Shipping Mark FAQ)

Are the two Chinese spellings of "shipping mark" the same thing?
Yes. In Chinese the term has two interchangeable spellings, and they mean exactly the same thing — in English, the Shipping Mark: the mark printed on a cargo's outer carton for identification and customs clearance. Formal trade documents tend to prefer one spelling, and the Chinese word itself is a phonetic loan of the English word "mark."
People sometimes write the term wrongly — is the misspelling still a shipping mark?
Yes. Because the Chinese characters sound almost identical, the term is often mistyped, but every version refers to the same thing: the Shipping Mark (the transport marking) printed on a cargo's outer carton for identification and customs clearance. Whichever spelling someone searches for, they are looking for the shipping mark.
What is the Chinese term for a shipping mark, and what is that term in English?
The Chinese term for Shipping Mark also translates as "transport marking" or "shipping marking"; conversely, the English for that Chinese term is simply Shipping Mark. A complete shipping mark is made up of a Main Mark, which identifies the cargo owner, and a Side Mark, which adds counting information.
What is the difference between the main mark and the side mark?
The main mark is the primary identifier and is mandatory; it includes the consignee abbreviation, reference number, destination port, piece number, country of origin, and so on. The side mark is supplementary information — contract number, gross and net weight, volume, box serial number (such as 1/10), and the like — that makes counting and sorting into boxes easier.
How do you write a shipping mark, and what is the minimum it must include?
Under paragraph 10 of UNECE Recommendation No. 15 (Simpler Shipping Marks, fourth edition ECE/TRADE/243), a standard shipping mark consists, in order, of 4 elements: the consignee's or buyer's English abbreviation, the reference number (waybill / order / invoice number), the destination, and the package number (e.g. 1/25); elements considered unnecessary may be omitted. In practice, gross weight, measurement and handling pictograms (fragile, this way up, keep dry — see also ISO 780:2015) are often added.
Do I need to add my own shipping mark to a Taobao consolidation parcel?
A regular B2C Taobao/1688 consolidation customer does not need to write a shipping mark. The consolidator collects and forwards the goods, and when you place your order it automatically labels the parcel with the warehouse address and your customer code; once the parcel reaches the warehouse, the consolidator identifies it and assigns it to your account. Only when you import commercial bulk cargo or arrange your own ocean freight do you need to prepare correct shipping marks yourself.
What happens if the shipping mark and the packing list do not match?
During an inspection, Customs checks the goods against the shipping mark and requires the mark on the carton to agree with the packing list, the bill of lading and the invoice. Any mismatch easily leads to a request for supplementary documents or to a physical examination, delaying release. Under Articles 2 and 5 of the Regulations for Correcting Declared Items on Import and Export Declarations, a declaration whose “marks” do not match the facts must be corrected by applying to Customs with supporting documents; and where Customs finds the documentary data questionable, it may refuse exemption from examination and inspect the cargo instead. Always make the shipping mark and the documents agree before shipping.
What does N/M (N.M.) mean?
N/M is the annotation for No Mark; Taiwan's customs clearance manual uses the form N/M (N.M. is also seen). An export declaration must state N/M if there is no shipping mark; and when the bill of lading for consolidated import cargo shows N/M, re-marking must first be applied for at the inspection and warehousing unit before the goods can be declared. So “not writing a shipping mark” is not cost-free on the import side — it is still advisable to show at least the consignee's abbreviation and the carton sequence number.
Is there a shipping-mark template or Excel file to download?
The “Shipping Mark Examples (Main Mark / Side Mark)” section on this page is itself a template you can copy directly: 5 lines for the main mark and 4 for the side mark. Select and copy them into Excel or Word, then replace the company's English name, the P/O number, the destination port and the carton numbers with your own data. HowBridge currently does not offer a separate Excel download — the main-mark fields required by each buyer and destination country differ, so it is better to use the example on this page as a draft and then check it item by item against your sales contract and packing list. For commercial bulk imports, HowBridge's AEO-certified partner customs broker can also draft the shipping mark and packing list for you.
Can HowBridge help with shipping marks and customs declaration?
Yes. HowBridge provides consolidation together with customs brokerage through an AEO-certified partner customs broker: for commercial bulk imports it can handle shipping marks, packing lists, and clearance documents on your behalf, while for regular Taobao consolidation the system assigns parcels to your account automatically, so you never have to write a shipping mark yourself.
Who is liable if the shipping mark is wrong, and what are the consequences?
Under Article 55 of the Maritime Act, the shipper “shall guarantee to the carrier the accuracy” of the notified description, number of packages and marks; the shipper is liable for damage, loss and expenses arising from an inaccurate notification. Article 54 further requires the bill of lading to state the kind and number of packages and the marks (Maritime Act, full text). In other words, for commercial cargo the accuracy of the shipping mark is the shipper's responsibility; a mismatch on the declaration side is corrected with supporting documents under the Regulations for Correcting Declared Items on Import and Export Declarations. Ordinary consumer consolidation customers never handle shipping marks — the consolidation system assigns parcels automatically — so this exposure does not arise.
What material and size should a shipping mark label be?
There is no legally required material or size. Coated and woodfree paper stickers are the norm and neither is waterproof: a splash is fine, soaking is not, so switch to synthetic stock or cover the label with clear tape on long ocean or cold-chain legs. Size it so you can read it standing beside a stacked pallet — A5 to A4 is common in practice. Keep it away from tape seams and the box-cutter path, apply one on each of two opposite faces, and for pallets make it visible on all four upright faces.
Is the mark on a pallet the same as the IPPC stamp?
No — different purpose, different place. The shipping mark is a commercial identifier (consignee abbreviation, reference number, destination, case numbers) applied to the carton or the outside of the stretch wrap for identification, counting and customs matching. The IPPC (ISPM 15) mark certifies phytosanitary treatment: under Taiwan's Plant Protection and Quarantine Act, solid wood pallets, crates and dunnage must first be heat treated (HT) or fumigated with methyl bromide (MB), after which an approved operator brands the mark into the timber — it cannot be re-applied by you or replaced with a sticker. Missing either can stop the shipment, but different authorities stop it: a mark mismatch is customs, a missing IPPC brand is plant quarantine. See our pallet and ISPM 15 guide.
