Article 8. Should the import duties on any articles of commerce produced in the Sulu Islands be reduced in Manila or Zamboanga to a lower rate than that now established, the Spanish Government will also make a reduction so that Sulu ships may always pay less, as has been agreed.
Should the Sultan of Sulu collect smaller duties from any foreign ship than those established for Spaniards, either as a tax or by a reduction of the valuation of the dutiable articles, he will be obliged to make such a reduction in duties for Spanish craft as will give the advantage to the flag of His Catholic Majesty as stipulated.
Last Article. Should the text of these articles of agreement differ in the two languages, the Spanish text will be literally adhered to.
