Standard shipping for a big item?

Hello everyone! I have a package stuck on June 3th in the status "package left sorting center of origin" and since then no updates have been made. Ik it's not too many days but always all my packages when left the sorting center of origin they arrived at the next step which is the airport in hours and for some reason this has been stuck in this status for 4 days. It's AliExpress standard shipping but it's a big item around 30cm (don't know the lbs/kgs) and idk if that plays a role, tho it's the AliExpress standard shipping not the oversized goods. Idk if being so big with this standard shipping plays a role but if anyone has an insight about anything, it would be a big help!

Thank you in advance!
