What a shipping mark is actually for
By the time an export crate reaches a terminal, everyone who made it has gone. What remains is a plywood box with writing on it. The shipping mark is that writing, and its job is to let someone who has never seen the shipment answer four questions without opening anything: whose it is, where it is going, which package of how many it is, and how heavy it is.
That is a narrower job than most people assume. A shipping mark is not a brand panel, not a product photograph and not a place for a slogan. Every mark on the box is read at a distance, in bad light, by someone in a hurry, so the value of a mark is inversely proportional to how much of it there is.
The marks that belong on the box
The order matters less than the consistency. What causes trouble is not a mark in the wrong corner; it is the same box marked two different ways on two shipments, or a package number that does not match the packing list.
| Mark | What it says |
|---|---|
| Consignee | Buyer name, or a short code if the buyer uses one |
| Destination | Port or city of discharge |
| Package number | 3 of 7, for example |
| Gross and net weight | In the unit the destination uses |
| Dimensions | Outside dimensions of the crate |
| Handling pictograms | This way up, keep dry, do not stack |
| Country of origin | Where the goods were made |
A shipping mark is not a treatment mark
These two get confused constantly, and the confusion has consequences.
A shipping mark is commercial information applied by the shipper. A wood-treatment mark is a statement that the wood in the package has been treated under a national plant-protection programme, and it is applied by whoever is authorised to apply it — not by the company that built the box, and not by the company that sells the machinery.
A plywood crate is normally outside that treatment regime because plywood is a processed wood product rather than solid wood. That does not make the box unmarked; it makes the treatment mark inapplicable. If a buyer asks for a treatment mark on a plywood box, the honest answer is that the material does not carry one, and the mill's panel documentation is what supports the claim.
Who supplies what
The information on the box comes from three places, and it is worth knowing which is which before the crates are built:
The mistake that recurs is printing the marks before the crate is finished. Outside dimensions change when a base is added or an edge profile is fitted, and a crate marked with the wrong dimensions will be planned into a container that it does not fit.
- The commercial documents — buyer, destination, package count, weights — come from the sales contract and the packing list.
- The physical dimensions come from the crate drawing, so they must be taken from the finished crate, not from the drawing of the part inside it.
- The handling pictograms come from how the crate must actually be lifted, which is a decision made when the base is designed.
The mistakes that cost the most
The four failures that come up most often are not exotic:
1. The package number is missing, so the receiver cannot tell whether the set is complete and signs for a partial delivery. 2. The weight on the box is the weight of the goods, not the gross weight of the crate. 3. Marks are applied to a face that will be against the container wall for the whole voyage. 4. The same crate carries two different consignee codes because the order was split after the crates were marked.
Each of these is cheap to prevent at the marking stage and expensive to resolve after the container has sailed.
Where the crate itself comes from
None of the above is a reason to buy a particular machine. It is, though, a reason to care how the crate is built: a box whose outside dimensions are consistent shipment after shipment is a box whose marks stay correct.
Our line builds plywood boxes from 5 to 12 mm with three core machines — a buckle machine that fastens panel joints at programmed positions, a steel-edge forming machine that rolls the edge profile, and a hydraulic press that closes the box on that edge. Three machines, one matched line. The repeatability that makes a mark reliable starts there, not at the stencil.
What to send us
If you are specifying marks for a set of export crates, send the packing list structure, the crate drawing and the route. We can tell you which fields have to be taken from the finished crate rather than the part, which is where most marking errors begin.
