R.I. Gen. Laws § 2-18.1-19
No transportation company or common carrier shall accept for transportation within this state, or deliver any box, bundle, package, bale, container, or other unit containing or consisting of nursery stock to any consignee within the state, unless the container or package has attached to it a copy of the official tag or certificate of inspection as required by this chapter and the regulations of the director. No common carrier or transportation company is liable for damages to the consignee or consignor for refusing to receive, transport or deliver any box, bundle, package, bale, container, or other unit containing or consisting of nursery stock to any consignee within the state, when not accompanied by the required tag or certificate. In case any nursery stock is shipped within this state without the certificate plainly affixed, the fact must be promptly reported to the department by the carrier, stating the consignor and the consignee and the nature of the shipment, and the carrier may be required to hold the shipment subject to the order of the director.
