Choosing the right customs form

You’ll need to fill out a customs declaration form for all parcels, International Courier letters and International Express letters you send overseas.

Save time by completing your customs declaration before lodging your parcel.

Not sure how to classify your item?
To be considered a letter or document, your package must:

  • weigh less than 500g
  • only contain printed material with no commercial value if you're sending overseas
  • have a rectangular shape
  • be no larger than a B4 envelope (260 x 360 x 20mm)
  • be no thicker than 20mm.

Guide to completing your customs declaration

Providing clear and accurate information on your International shipment helps your items clear destination customs. Without this information, your shipment may be held up or returned to you, resulting in unnecessary delays and a poor delivery experience for the recipient of your items.
