Parcels sent abroad are subject to inspection by foreign customs, basically in the form of random checks, and this situation is an irresistible factor.
If Customs considers your parcel to be special (e.g. large, too heavy or containing sensitive items), they will generally take the initiative to contact the recipient to provide an invoice or customs clearance documents.
The cost of returning or destroying the parcel due to failure to contact the recipient or the recipient’s failure to cooperate in taking the initiative to contact Customs for clearance will be borne by the recipient. All losses will also be borne by the recipient.
