Structures

## What it means in packaging

The code makes a structure easier to specify across languages. It describes a construction, not a particular size, board grade or performance rating. The drawing and production specification still need those details.

## A practical example

FEFCO 0201 describes a familiar slotted case construction; a small and a large case can share that code.

## What to check

Confirm the code against the actual structure and agree dimensions, board and closure requirements separately.
