United States Postal Service Exemption Codes

Do you have a holiday package you need to ship out of the country?

We have received many calls from customers using the United States Postal Service (USPS) website.

When you visit the USPS.com, it gives several options to choose from when supplying package information to the site for proper mailing (‘Enter Customs Information’). Let us clarify a couple of key elements:

Proof of Filing Citation (PFC): notification confirming that you filed to the Automated Export System. This is also known as the Internal Transaction Number or ITN.
AES Exemption : If you are not required to file, this note indicates why you are exempt from filing.

Choosing the Appropriate Exemption

On USPS.com, the two main options to choose from are: 30.36 and 30.37(a). Take a look at what they mean:

• 30.36: Use for shipments destined to Canada that do not require a license, regardless of value.
• 30.37(a): Use for shipments under $2,500 destined to countries other than Canada that do not require a license.
