, Question 1
A customer presents a sealed, rigid box containing a lithium-ion battery pack
(installed in a laptop) for domestic Priority Mail shipment. The battery is rated
at 100 Wh. Which of the following is the correct USPS acceptance procedure?
A. Accept as Priority Mail if the battery is installed in the device and the
package bears a lithium battery handling label.
B. Refuse because lithium-ion batteries are prohibited in all USPS
domestic air transportation.
C. Accept only via surface transportation and require the customer to sign
a hazardous materials declaration.
D. Accept as Priority Mail Express only, since it allows lithium batteries
up to 160 Wh.
Correct Answer: A - Accept as Priority Mail if the battery is
installed in the device and the package bears a lithium battery
handling label.
RATIONALE
USPS mails lithium batteries installed in equipment (UN3481)
domestically when they meet watt-hour limits (100 Wh per battery)
and bear the required handling label. Option B is incorrect because
installed batteries are mailable with restrictions. Option C is wrong
because surface-only restrictions apply to standalone batteries, and no
signature declaration is required for installed batteries. Option D is
false; Priority Mail Express does not grant higher Wh allowances.
Question 2
A mailer wants to send a First-Class Mail letter weighing 3.5 oz with a
Certificate of Mailing (Form 3817). What is the correct postage and fee
combination?
A. First-Class Mail rate for 3.5 oz plus the Certificate of Mailing fee.
B. First-Class Mail rate for 3.5 oz plus Certified Mail fee.

Correct Answer: A - First-Class Mail rate for 3.5 oz plus the
Certificate of Mailing fee.
RATIONALE
Certificate of Mailing provides evidence of mailing and requires the
applicable First-Class Mail postage plus the Certificate of Mailing fee.
Option B is incorrect because Certified Mail provides a mailing
receipt and tracking, not just evidence of mailing. Option C is wrong
because Priority Mail is not required for a 3.5 oz letter. Option D is
false; Certificate of Mailing is not free.
Question 3
Which of the following statements accurately describes the difference between
USPS Tracking and Signature Confirmation regarding electronic return
receipt?
A. USPS Tracking includes a signature upon delivery, while Signature
Confirmation does not.
B. Signature Confirmation provides a delivery signature record, while
USPS Tracking provides delivery status without signature.
C. Both services provide a signature, but only USPS Tracking includes
electronic return receipt.
D. Neither service provides a signature; electronic return receipt is only
available with Certified Mail.

signature record, while USPS Tracking provides delivery status
without signature.

, RATIONALE
Signature Confirmation captures the recipient's signature at delivery,
whereas USPS Tracking only provides scan events and delivery status
without a signature. Option A reverses the services. Option C
incorrectly attributes signature to USPS Tracking. Option D is false
because Certified Mail can also provide electronic return receipt, but
Signature Confirmation itself provides signature.
Question 4
A customer is shipping a package to an international destination and asks about
customs forms. The package contains items valued at $300 and weighs 3 lbs.
Which customs form is required?

B. PS Form 2976-A (CN 23) and PS Form 2976 (CN 22) if using Priority
Mail International.

Correct Answer: B - PS Form 2976-A (CN 23) and PS Form 2976
(CN 22) if using Priority Mail International.
RATIONALE
For international packages valued over $400, PS Form 2976-A is
required; however, for values up to $400, PS Form 2976 (CN 22) may
be used for certain services. For Priority Mail International, both
forms may be required depending on value and service. Option A is
incomplete for higher value. Option C is wrong because the threshold
for CN 23 is $400, not $400. Option D is false; customs forms are
mandatory for international mail.
