I bought clothes from china.. and im checking USPS withmy tracking number and is inboung into customs?? help?

Inbound into customs means it's currently in customs and once it's been cleared you should receive it within a day or 2. Customs can take anywhere from 1 day-1 month to clear a package just depending on the value of it's contents and what it is. But I'd say since it's already been in customs for a week & it's only clothing it should be released fairly soon.
