To the extent allowed by law, user shall include in its Bills of Lading a clause incorporating the United States Carriage of Goods by Sea Act, 46 U.S.C. Section 30701, formerly codified at 46 U. S. C. Section 1301, et seq., (‘COGSA’), extending the benefits and limitations contained in the Bill of Lading and COGSA to terminal operators and to the period prior to loading and subsequent to discharge while cargo is in the custody of GPA, and giving the shipper an option to effectively declare a higher value for its cargo than the package limitation.  If such provisions do not exist or are waived by user, or if the shipper declares a higher value of cargo, user shall notify GPA Risk Management of such waiver, omission, or declared value in writing at least five (5) days prior to the arrival of the cargo in question whether import or export cargo, to allow GPA the opportunity to obtain the necessary insurance to cover the additional exposure, the cost of which will be billed to user.
