N.D. Cent. Code § 35-31-01
Any person who furnishes supplies used in the production of crops, agricultural products, or livestock is entitled to a lien upon the crops, products produced by the use of the supplies, and livestock and their products including milk. As used in this chapter, the term "supplies" includes seed, petroleum products, fertilizer, farm chemicals, insecticide, feed, hay, pasturage, veterinary services, or the furnishing of services in delivering or applying the supplies. Except as otherwise provided in this section, an agricultural supplier's lien filed in accordance with section 35-31-02 is effective from the date the supplies are furnished or the services performed. An agricultural supplier's lien filed as a security interest created by contract to secure money advanced or loaned for any purposes is not effective to secure a priority over liens filed under section 35-05-01. This chapter does not limit the sale, assignment, or transfer of an agricultural supplier's lien. However, the priority of an effective agricultural supplier's lien is not transferable from the original lienholder. After sale, assignment, or transfer, the priority of an effective agricultural supplier's lien is to be determined as of the date the lien was filed and in accordance with section 41-09-33.
