At the moment of proceeding to the signature of the Supplementary Agreement to the International Convention for the Abolition of Import and Export Prohibitions and Restrictions signed on this day's date, the undersigned, duly authorised, have agreed on the following provisions, which are intended to ensure the application of the Supplementary Agreement:

The High Contracting Parties declare that, in the text of the Supplementary Agreement of this day's date, the expression "the Convention" shall be taken to mean both the International Convention for the Abolition of Import and Export Prohibitions and Restrictions dated November 8th, 1927, and the Supplementary Agreement of this day's date.

(a) Cork in the raw state, in respect of which an exception has been allowed for Portugal, does not include scrap cork, or cork in agglomerated form, in shavings, or in sheets.

(b) Although the exceptions set out in Article 1, like these appearing in the Annex to Article 6 of the Convention, have been allowed on the condition that the countries benefiting thereby shall sign the present Supplementary Agreement on the day of the general signature, it has appeared equitable to grant an extension of time up to August 31st, 1928, inclusive, to Bulgaria, Portugal and the United States of America.

(c) As regards the exception of hop shoots which has been agreed to in favour of Czechoslovakia under paragraph 1 of Article 6 of the Convention, the High Contracting Parties declare that their consent has been given in return for the written undertaking entered into by the Czechoslovak delegation to allow the free export of this product to all countries which now or in the future guarantee Czechoslovakia by legislative or contractual measures the protection of the appellation of origin of Czechoslovak hops.

The High Contracting Parties agree to recognise in the case of Italy the application of the provision of the Protocol to the International Agreement relating to the Exportation of Bones [Section I, ad Article I (a)], in the event of the said Agreement coming into force.

(a) Owing to the position of the United States in consequence of a short Session of Congress in the year 1928-29, the High Contracting Parties agree that, if the ratification of the United States has been asked for under paragraph 3 of Article C and has not been deposited by September 30th, 1929, the Convention shall came into force on January 1st, 1930, provided that all the other countries on which the entry into force of the Convention depends and the total number of which would in this case be reduced to seventeen shall have notified the Secretary-General of the League of Nations of their ratifications or accessions before September 30th, 1929, and provided no objection is raised before November 15th, 1929, by any of the countries which, at the time of the deposit of their ratification or accession, made the entry into force of the Convention, in so far as they were concerned conditional upon the ratification or accession of the United States. If any objection is raised, the last paragraph of Article 17 of the Convention shall apply.

(b) The High Contracting Parties declare that, in drawing up the list of countries which appears in Article C, they have been chiefly guided by the interdependence of certain interests emphasised in the course of the proceedings of the Conference.

They have thought it unnecessary to mention countries the inclusion of which would be justified only by the importance of economic interests or considerations of geographical situation.

If they have not mentioned certain countries, it is because those countries at present impose no prohibitions of any importance. The High Contracting Parties think they can rely upon their ratification or adhesion.

IN FAITH WHEREOF the above-mentioned Plenipotentiaries have signed the present Protocol.

DONE at Geneva on the eleventh day of July, and thousand nine hundred and twenty-eight, in a single copy, which shall be deposited in the archives of the Secretariat of the League of Nations; certified true copies shall be forwarded to all the Members of the League of Nations and to all the non - Member States represented at the Conference.

I declare that my signature does not include any of His Britannic Majesty's Colonies, Protectorates or territories under suzerainty or mandate.

Subject to the reservation made on signing the Supplementary Agreement.
