A non-machinable stamp marks mail that cannot go through USPS sorting machines — rigid, lumpy, or oddly shaped pieces. This self-inking Non-Machinable stamp prints a 9/16" × 1-1/2" red handling mark so clerks and carriers see the surcharge category at a glance. Mailrooms and small shippers stamp envelopes and flats before they hit the counter. The pad is refillable; impressions stay sharp for daily outgoing batches. Use it with your other shipping stamps (media mail, fragile) so each piece carries the right handling language.

Bought this after too many fragile shipments were treated like regular freight. Faster than writing the same handling note on every package. Staying on our packing station for good.

I mark every carton with Non Machinable before it hits the carrier stack. Faster than writing the same handling note on every package. Exactly the package mark we needed.

I stamp Non Machinable on outgoing parcels so handlers see the warning before tossing the box. The imprint is large enough to catch attention on brown boxes. Exactly the package mark we needed.

Our shipping table needed a bold handling mark that survives tape and labels. The imprint is large enough to catch attention on brown boxes. Clear handling cues with less writing.
