Each licensed warehouseman shall insure and keep insured against loss or damage by fire, theft, burglary, and other hazards which are commonly insured against, under "extended coverage" provisions, for its full value, all cotton and other products on storage unless requested by the depositor in writing not to insure the cotton or other products and in that instance when the cotton or other products are not insured a statement to that effect must be plainly and conspicuously inserted on the face of the receipt. In case of loss, the warehouseman shall collect the insurance due and pay it ratably to those lawfully entitled to payment. The warehouseman may accept contracts for the storage of cotton submitted by the Commodity Credit Corporation and other United States governmental agencies without being required to carry insurance on the cotton. As a condition of license, each warehouseman shall maintain on file with the department a current certificate of insurance setting forth the policy number, the agent and underwriter, the provisions and limits of coverage, and the date the policy expires.
