1536 FRIENDSHIP. ETC.. TREATY-POLAND. JUNE 15, 1931. respectively, conform to the provisions above set forth, it being understood and agreed, however, that (a) If the circumstances of any particular case render it impracticable for the shipper of the goods to obtain certification on a certificate of origin by a Chamber of Commerce or similar organization, the certificate of origin may be submitted for authentication directly to a Polish consular officer, and the fact that certification by a Chamber of Commerce or similar organiza- tion has not been obtained shall not be considered by such consular officer as of itself sufficient ground for refusing to authenticate the document. (b) If at the time the certificate of origin is made out cir- cumstances render it difficult or inconvenient for shippers to specify on such certificate the name of the vessel on which the goods are to be shipped, the necessities and convenience of shipl?ers shall be taken into account either by waiving this reqUIrement or by making such other provision as the circum- stances of the case require. (c) In exceptional cases in which doubt exists regarding the exact proportion of the value of any given article represented by the costs of the labor and raw material of the United States, or in which such proportion is less than fifty per centum, but the arti- cle, in view of the nature and extent of the processes to whi~h it has been subjected, is distinctly an American product, no certifica- tion regarding such proportion on a certificate of origin shall be required. Any article in which the raw material or the labor of the United States represents less than fifty per centum of the total value shall, nevertheless, be deemed to be a product of the United States if a like article from any third country representing less than fifty per centum in value the labor and raw material of such third country is deemed to be a product of that country. (4) In the event that modification of the requirements outlined in the preceding paragraphs is at any time considered desirable from the viewpoint of either Party, it is agreed that its proposals to this end shall be given sympathetic consideration by the other Party. I shall be glad to have your confirmation of the accord thus reached. Accept, Excellency, the renewed assurances of my highest considera- tion. HENRY L.
