I have a package, LP186192577GB, that latest status has it in customs , needing to pay duty tax. However the receiver has not received any notice. Is there a way for the receiver to get notfitication via text to personal phone or mail to shipping address to pay duty tax?

I returned a parcel to China via Royal Mail Uk, when I track it is saying either missing customs paperwork or duty to be paid, the item is below value for duty and the paperwork was attached, how do I contact customs with a copy of the paperwork. Thank you

My item: RY443248095GB
My package arrived at customs in Chengdu, Sichuan on 4th December. It shows as 'awaiting duty payment' however I have not received any messages requesting the payment. It is now 6th December. I want to pay the duty and receive the item, but how can I pay the duty without receiving a message?

How long will it take to receive a message requesting the payment? Is there a way to pay the duty without receiving a message from customs first?

Regards,
Nick.
