All goods imported, unless particularly exempted, and such exemptions are not very numerous, are liable to some duties of customs. If any goods are imported, not mentioned in the book of rates, they are taxed at 4s:9ѕd. for every twenty shillings value, according to the oath of the importer, that is, nearly at five subsidies, or five poundage duties. The book of rates is extremely comprehensive, and enumerates a great variety of articles, many of them little used, and, therefore, not well known. It is, upon this account, frequently uncertain under what article a particular sort of goods ought to be classed, and, consequently what duty they ought to pay. Mistakes with regard to this sometimes ruin the custom-house officer, and frequently occasion much trouble, expense, and vexation to the importer. In point of perspicuity, precision, and distinctness, therefore, the duties of customs are much inferior to those of excise.
In order that the greater part of the members of any society should contribute to the public revenue, in proportion to their respective expense, it does not seem necessary that every single article of that expense should be taxed. The revenue which is levied by the duties of excise is supposed to fall as equally upon the contributors as that which is levied by the duties of customs; and the duties of excise are imposed upon a few articles only of the most general used and consumption. It has been the opinion of many people, that, by proper management, the duties of customs might likewise, without any loss to the public revenue, and with great advantage to foreign trade, be confined to a few articles only.
The foreign articles, of the most general use and consumption in Great Britain, seem at present to consist chiefly in foreign wines and brandies; in some of the productions of America and the West Indies, sugar, rum, tobacco, cocoa-nuts, etc. and in some of those of the East Indies, tea, coffee, china-ware, spiceries of all kinds, several sorts of piece-goods, etc. These different articles afford, the greater part of the perhaps, at present, revenue which is drawn from the duties of customs. The taxes which at present subsist upon foreign manufactures, if you except those upon the few contained in the foregoing enumeration, have, the greater part of them, been imposed for the purpose, not of revenue, but of monopoly, or to give our own merchants an advantage in the home market. By removing all prohibitions, and by subjecting all foreign manufactures to such moderate taxes, as it was found from experience, afforded upon each article the greatest revenue to the public, our own workmen might still have a considerable advantage in the home market; and many articles, some of which at present afford no revenue to government, and others a very inconsiderable one, might afford a very great one.
High taxes, sometimes by diminishing the consumption of the taxed commodities, and sometimes by encouraging smuggling frequently afford a smaller revenue to government than what might be drawn from more moderate taxes.
When the diminution of revenue is the effect of the diminution of consumption, there can be but one remedy, and that is the lowering of the tax.
When the diminution of revenue is the effect of the encouragement given to smuggling, it may, perhaps, be remedied in two ways; either by diminishing the temptation to smuggle, or by increasing the difficulty of smuggling. The temptation to smuggle can be diminished only by the lowering of the tax; and the difficulty of smuggling can be increased only by establishing that system of administration which is most proper for preventing it.
The excise laws, it appears, I believe, from experience, obstruct and embarrass the operations of the smuggler much more effectually than those of the customs. By introducing into the customs a system of administration as similar to that of the excise as the nature of the different duties will admit, the difficulty of smuggling might be very much increased. This alteration, it has been supposed by many people, might very easily be brought about.
The importer of commodities liable to any duties of customs, it has been said, might, at his option, be allowed either to carry them to his own private warehouse; or to lodge them in a warehouse, provided either at his own expense or at that of the public, but under the key of the custom-house officer, and never to be opened but in his presence. If the merchant carried them to his own private warehouse, the duties to be immediately paid, and never afterwards to be drawn back; and that warehouse to be at all times subject to the visit and examination of the custom-house officer, in order to ascertain how far the quantity contained in it corresponded with that for which the duty had been paid. If he carried them to the public warehouse, no duty to be paid till they were taken out for home consumption. If taken out for exportation, to be duty-free; proper security being always given that they should be so exported. The dealers in those particular commodities, either by wholesale or retail, to be at all times subject to the visit and examination of the custom-house officer; and to be obliged to justify, by proper certificates, the payment of the duty upon the whole quantity contained in their shops or warehouses. What are called the excise duties upon rum imported, are at present levied in this manner; and the same system of administration might, perhaps, be extended to all duties upon goods imported; provided always that those duties were, like the duties of excise, confined to a few sorts of goods of the most general use and consumption. If they were extended to almost all sorts of goods, as at present, public warehouses of sufficient extent could not easily be provided; and goods of a very delicate nature, or of which the preservation required much care and attention, could not safely be trusted by the merchant in any warehouse but his own.
If, by such a system of administration, smuggling to any considerable extent could be prevented, even under pretty high duties; and if every duty was occasionally either heightened or lowered according as it was most likely, either the one way or the other, to afford the greatest revenue to the state; taxation being always employed as an instrument of revenue, and never of monopoly; it seems not improbable that a revenue, at least equal to the present neat revenue of the customs, might be drawn from duties upon the importation of only a few sorts of goods of the most general use and consumption; and that the duties of customs might thus be brought to the same degree of simplicity, certainty, and precision, as those of excise. What the revenue at present loses by drawbacks upon the re-exportation of foreign goods, which are afterwards re-landed and consumed at home, would, under this system, be saved altogether. If to this saving, which would alone be very considerable, were added the abolition of all bounties upon the exportation of home produce; in all cases in which those bounties were not in reality drawbacks of some duties of excise which had before been advanced; it cannot well be doubted, but that the neat revenue of customs might, after an alteration of this kind, be fully equal to what it had ever been before.
If, by such a change of system, the public revenue suffered no loss, the trade and manufactures of the country would certainly gain a very considerable advantage. The trade in the commodities not taxed, by far the greatest number would be perfectly free, and might be carried on to and from all parts of the world with every possible advantage. Among those commodities would be comprehended all the necessaries of life, and all the materials of manufacture. So far as the free importation of the necessaries of life reduced their average money price in the home market, it would reduce the money price of labour, but without reducing in any respect its real recompence. The value of money is in proportion to the quantity of the necessaries of life which it will purchase. That of the necessaries of life is altogether independent of the quantity of money which can be had for them. The reduction in the money price of labour would necessarily be attended with a proportionable one in that of all home manufactures, which would thereby gain some advantage in all foreign markets. The price of some manufactures would be reduced, in a still greater proportion, by the free importation of the raw materials. If raw silk could be imported from China and Indostan, duty-free, the silk manufacturers in England could greatly undersell those of both France and Italy. There would be no occasion to prohibit the importation of foreign silks and velvets. The cheapness of their goods would secure to our own workmen, not only the possession of a home, but a very great command of the foreign market. Even the trade in the commodities taxed, would be carried on with much more advantage than at present. If those commodities were delivered out of the public warehouse for foreign exportation, being in this case exempted from all taxes, the trade in them would be perfectly free. The carrying trade, in all sorts of goods, would, under this system, enjoy every possible advantage. If these commodities were delivered out for home consumption, the importer not being obliged to advance the tax till he had an opportunity of selling his goods, either to some dealer, or to some consumer, he could always afford to sell them cheaper than if he had been obliged to advance it at the moment of importation. Under the same taxes, the foreign trade of consumption, even in the taxed commodities, might in this manner be carried on with much more advantage than it is at present.
