📌 Safety pins

Nothing — safety pins are permitted in carry-on and checked baggage worldwide, so screeners will simply wave them through. A pouch or small container full of pins may prompt a brief bag search just so the officer can confirm what they are, but confiscation is not on the table.

No meaningful regional restrictions exist for safety pins. Every major aviation authority classifies them as permitted sharp objects in both cabin and hold baggage, so you do not need to adjust your packing based on your destination or transit points.

It is very unlikely. Closed safety pins are a recognised, low-risk item and TSA explicitly notes they pose no security concern. A large, loose collection of metal pins might cause a brief second look on the X-ray screen, but screeners generally move them through without a secondary bag check.

Close every pin before packing them — an open pin can snag fabric, pierce a toiletry bag, or catch on cables and cause a tangle. A small zip-lock bag or a fabric pin roll keeps them contained and makes the cluster easier to identify quickly on an X-ray screen.
