Customs not releasing my parcel from last 20days

Is this normal?

I ordered a watch from an e-commerce website, and it was shipped from the Netherlands. It arrived in India on 23 June and has been stuck in customs since that date. I haven't received any updates or responses from customs yet.

Is it normal for a parcel to be held by customs for this long, or should I be doing something about it?

Thanks in advance to anyone who can help. :)
