This way up (two arrows)

The box must travel and be stored with the arrows pointing up: the side the arrows point to is the top.

Who puts it on the box

The sender or packer prints or sticks it on, usually on all four upright sides, because the contents would spill, leak or break if the box were laid on its side or turned over.

How to read it

Keep the arrows pointing to the ceiling when you carry, stack or store the box. When you open it, open the top the arrows point to. ISO 780:1997 put the arrows near the top left corner of all four sides, and closer to the corner than the glass when both marks are used; the 2015 edition still fixes where and how many.

What it does not promise

It does not promise the box stayed upright: parcel conveyors, chutes and delivery vans turn boxes over, and a mark cannot stop them. It does not promise the contents are a liquid or a dangerous good either — that is what the red or black orientation arrows of the dangerous-goods rules and the hazard labels are for.

A mark on a parcel is the sender’s statement about what is inside and how it should be handled. It is not a certificate that the parcel is packed safely, that anyone handled it as marked, or that your carrier accepts it: for what you may send, read the carrier’s own terms.

What it looks like
Two parallel arrows pointing up, standing on a short horizontal bar, printed in black near the top corner of the box sides.
Standard
ISO 780:2015, symbol No. 13 — This way up
Kind of mark
A handling symbol from ISO 780, the international standard for handling marks on distribution packages. ISO 780 marks are always black; they say how to handle the package, never that its contents are dangerous.
