Hi, my parcel tracking no. RC781391135SG has been held by customs. My local (Singapore) postal company said that reason is due to missing invoice of the item. They require the recipient to send them the invoice, but the recipient is a large corporation and seems unwilling to help me respond to customs, and instead sent me the e-invoice for me to forward it to China customs. However, I'm unable to contact China customs, is there any email I can send the invoice to so that they can help me forward my e-invoice to the customs for the release of my parcel? Pleaseee and thank you!

Is there a way to forward the invoice to customs? My parcel has no invoice as it is not intended for sale, but the customs ask me for the invoice together with "Cargo Declaration Materials from Addressee". How should i behave?

Hi can you assist me as my package is being held by customs and is missing an invoice, how can i get a copy of the the invoice.
