For me, the only way to go is USPS as I have a PO Box number.
I don't know on your end, but for small packages all I see is a very small (2 x 3) customs declaration label that states what is in the package (antique car part, etc.), the value, your signature and the date.
Let me know if this is something that you would like to pursue.
Here is what I got from the USPS website (
123 Customs Forms and Online Shipping Labels) for Standard International Mail delivery:
123.1 General
Only two customs declaration forms are used, as required under 123.6, for international mail: PS Form 2976, Customs Declaration CN 22 — Sender’s Declaration (green label); and PS Form 2976–A, Customs Declaration and Dispatch Note — CP 72. PS Form 2976–E, Customs Declaration Envelope — CP 91, is used as a carriage document for PS Form 2976–A.
Note: The current edition of PS Form 2976 is December 2009; the current edition of PS Form 2976-A is May 2009; the current edition of PS Form 2976-E is September 2006. Except as provided in 123.3 and 123.5, mailers must present at the time of mailing a fully completed sender’s declaration (the Post Office™ copy of PS Form 2976 or 2976-A), which specifies both the sender’s name and address and the addressee’s name and address.
123.2 Availability
Customs declaration forms are available without charge at Post Office facilities. Upon request, mailers may receive a reasonable supply for mail preparation. Customers may also order supplies of the customs forms from The Postal Store at
http://shop.usps.com; search on the words “customs forms.” Customs declaration forms are also available through an online customs form application at usps.com/webtools.
