How long does a package take to get from hong kong to the usa?

I ordered Iphone cases off of amazon from the sellers eFurture WE MARKET and Ocean-City They are shipping from hong kong and I ordered them 1 1/2 weeks ago. I ordered something from hong kong a few weeks ago and it wasn't supposed to get here between the 11th and the 28th and I ordered it on the 15th of january but it got here like 1 week after I ordered it. I really want my phone cases because I'm using my sisters old broken case right now. They don't having traking information on them and the deleviy estimate is between Feb 21-mar 11.

Call the amazon number.

My rule of thumb (over many) EMS parcels from Hong Kong is 11-25 days.
