Help!Global Express mail inbound Into Customs

My family sent a Global Express mail from China to SF 4 weeks ago.
I haven't gotten it yet. The first mail we recieved only in 2 weeks.
I went to the internet checked the tracking number,and it showed "Your item is being processed by United States Customs"

"Inbound Into Customs
Inbound International Arrival, November 07, 2008, 9:50 am, ISC SAN FRANCISCO (USPS)"

Anyone here knows what's going on?
How long does it take if it is hold in Custom?
Thanks
