關於寄usps申請賠償的問題 - 海外購物

我在USPS的官網看到寄Airmail Parcel Post關於寄丟賠償的內容

Ordinary air parcel post includes indemnity at no cost based on weight.
For an item not over 1 pound, the indemnity is $62.84, and the indemnity
increases $3.03 per pound or fraction up to a maximum of 70 pounds, which
has an indemnity of $271.91.

另外在官網對於Parcel post的賠償如下

Ordinary parcel post includes indemnity against loss, damage,or rifling up
to the amounts shown in Exhibit 281.4. Indemnity is limited to the lesser of
the actual value of the contents or the maximum indemnity based on the
weight of the article. If the parcel has been delivered to the addressee,
payment for damage and missing contents is made to the addressee unless the
addressee waives payment, in writing, in favor of the sender.

Note: International insured mail service provides insurance coverage higher
than the indemnity limits for ordinary parcel post to many countries.

假如我的package真的弄丟了，我該如何申請賠償?
忘了說，我沒有加買保險
