各位大侠看看，我的邮包是不是被美国海关扣了呀？

货是从香港发出来的。12月27日发出的。是航空件。
Bullet Inbound Into Customs
Bullet Inbound International Arrival, January 02, 2009, 8:03 am, ISC SAN FRANCISCO (USPS)
Bullet Foreign International Dispatch, December 27, 2008, 4:02 pm, HONG KONG AIR MAIL CENTRE, HONG KONG
Bullet Foreign Acceptance, December 27, 2008, 2:47 pm, HONG KONG

到现在也没什么更新，我该怎么办呀？
