The Wealth of Nations_ Books 4-5 - Adam Smith [297]
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, cocoanuts, 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, perhaps, at present, the greater part of the 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 the 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
