Besides the above there are some ninety-five articles or products on which specific duties are imposed. Since 1900 a legislative factor, at first sight unimportant, but in practice of the greatest advantage, has to a certain extent modified the vexatious character of the Argentine tariff. This factor consists in the relative stability imposed by Congress on the customs law, by the suppression of the annual revision to which the rate of valuation was subjected, which change has allowed commerce to establish its transactions on a definite basis; whereas they were formerly contingent upon the continual modifications of the said tariff. This step, like so many others, was initiated by the ex-Minister, Señor José Maria Rosa. Exaggerated values were always at the base of these tariffs, and the abuse became so notorious that the present Minister of Finance, Dr Terry, was himself obliged to recognise “that reform was essential in the matter of the rectification of all these valuations, in order that the Customs Administration should not strike indirectly at imported products by taxes far in advance of those intended by the legislative power.” A new tariff has been in force since the 1st of January 1905, and although it also has given rise to a certain degree of recrimination, it is none the less an improvement upon the former state of affairs. As for the export duties, here again we find notable discrepancies between the valuations and the market prices which ought, on principle, to serve as their basis. They were established after the crisis of 1890, and as they were now no longer justified by insufficient resources, they were suppressed by Congress reckoning from 1906. These customs duties on exported goods were established by the Argentine Constitution, but not in a permanent manner. The Charter enacted that they should be in force up to 1866; but at that time, the country being at war with Paraguay, a Convention was convoked, which postponed the settlement of the matter for some years. In 1887 the export duties were suppressed; but in 1900, after the terrible financial crash, they were once more established, in order to relieve the heavy burdens and engagements of the Treasury. These duties were from 4 to 100 per cent. _ad valorem_, and were principally directed against leathers and hides, wool washed or unwashed, ostrich plumes, tallow, fat, animal oil, horns, etc.
