Can anyone kindly confirm if this tax is being collected on international departures?

And if someone came with personal jewelry on them in Pakistan a month ago, will they be asked to pay tax on it or allowed to take it back without any hassle? Someone sent me this and I’m confused: https://imgur.com/a/RTqsTbS

Appreciate the help, thanks!
