A transport service covering carriage from seller´s premises to the buyer´s premises. This term refers to a freight in a carriage contract between a carrier and a shipper and thus is distinct from the issue of the Incoterms chosen in the contract of sale (an agreement between seller and buyer). Depending on the circumstances of the transaction, it could be possible to quote prices on either EXW, FCA, CPT, CIP, DP or DDP Incoterms in conjunction with so-called house-to-house transport services. Attention should be given to the inclusion of loading (unloading charges in the house-to-house rate, especially in comparison with the responsibility under the respective Incoterms for loading or unloading). The shipper should make sure that the transport service corresponds to the contractual obligations under Incoterms. It is sometimes said that door-to-door services imply that loading and unloading are not included in the freight charge. Door-to-door is sometimes used as synonymously with house-to-house, but it is claimed by some that here is a distinction between the two, namely that house-to-house only refers to rental rates for containers from container yard to container yard. See house-to-house.
