O.C.G.A. § 46-9-191: Lien of carrier for freight charges.

When a carrier has complied with his contract as to transportation, he shall have a lien on the goods for the freight charges and may retain possession until the lien is paid, unless this right is waived by special contract or actual delivery of the goods. If the goods are delivered, the carrier acquires a lien for the freight charges on and may until the lien is paid retain possession of other goods belonging to the debtor which come into the possession of the carrier. The immediately preceding sentence shall not apply to consumer goods which are used or bought for use for personal, family, or household purposes, except when a motor carrier of household goods and office furnishings may retain possession of such goods.
