§ 2. #Specific and ad valorem rates.# Before entering upon the history of the American policy let us make clear the meaning of certain technical terms and explain certain methods which are frequently referred to.
Rates (and duties) may be by either specific or ad valorem. Specific duties are those that are calculated and levied according to some physical test, as so much per pound, per yard, per hundred-weight, or per ton. Ad valorem duties are those that are calculated and levied according to the value of the goods (usually as it was at the place of shipment) determined by an assessor, by invoice of sale, by statement of the importer under oath, etc. The actual duty collected on any article may result from various combinations of the two rates (as, to take an actual example, $4.50 a pound and 25 per cent ad valorem on cigars and cigarettes) or ad valorem with a minimum valuation so that on the cheaper goods the rate is specific.
Specific rates are more easily applied in administration, not offering the temptation to undervaluation and misrepresentation that ad valorem rates do; on the other hand, specific rates do not adjust themselves to price changes as ad valorem rates do. If the prices of goods go up the specific rate is relatively less and affords less of "protection" to the domestic producer; whereas if prices go down (as, in general trend, the prices of manufactured goods have done most of the time) the specific duties are relatively greater. To take a historical example, the specific rate of 6-1/4 cents a yard on cotton goods in 1816 which was at first in fact only about 25 per cent, within a few years became about 75 per cent and absolutely prohibitive. For this reason specific rates have most often been used in acts intended to increase the "protective" duties and often as a device for immediately raising rates; while ad valorem rates have been more often used in acts prompted by the desire for less drastic exclusion and for a more adequate revenue; but there is no essential connection between the protective policy and specific rates. Indeed, in the period from 1897 to 1909, when most prices were rising, many of the specific rates under the Dingley Act, intended to be strongly protective, afforded less and less "protection."[1]
§ 3. Some technical features of the tariff. All goods not subject to duties are said to be on the free list. It is customary to group articles in schedules, of which there are fourteen in the law of 1913, designated from A to N (for chemicals, pottery, metals, wood, etc.), but the rates are not uniform for all the articles in each schedule. Drawbacks are a certain amount, the whole or a part, of the duties that have been paid on imported commodities, which is paid back by the government on the reëxportation of the goods. Compensatory duties (or compensatory rates) are those levied on certain manufactured articles with the purpose of raising their price as much as domestic producers' costs are raised by a tariff on their raw materials. Examples are a duty on woolen goods to offset a duty on wool, or a duty on shoes to offset one on hides. They may be intended to be partial or complete or more than sufficient, and are likely in any case to work either more or less to the advantage of the domestic producer than was intended. It may be that the conditions of supply are such that the home price of the raw materials is raised little or none by the tariff while the price of the finished product is considerably raised, or vice versa.
§ 4. #The tariff, 1789-1815.# The main difficulty of government in 1781-1789 under the Articles of Confederation was lack of the power to obtain revenues by taxation. The separate states alone could levy duties, and a good many tariff restrictions on freedom of trade among them developed in this period. The Constitution established the principle of entire freedom of trade among the states. The first act of Congress under the Constitution levied a tariff, primarily for revenue purposes, but clearly having a protective purpose, in the view of some of the representatives. However, most of the separate rates, as well as the general average rate, were the lowest ever levied by Congress, except that there was no free list and that 5 per cent was imposed upon all goods not otherwise enumerated. Ad valorem duties up to a maximum of 15 per cent (that on carriages) were laid upon certain articles of luxury, and low specific duties on a few articles such as glass, nails, iron manufactures, hemp, and cordage.
From 1789 until 1812, thirteen tariff laws, all told, were passed. One after another many rates were raised to get larger revenues, but some goods were put upon the free list. The foreign trade, in both imports and exports, grew largely and with considerable regularity, rising then rapidly to a maximum in 1807. Then followed troublous times, with British Orders in Council and our embargo and nonintercourse acts until 1812, and war until 1815, trade falling off at first to one-half, and at last (in 1814) to less than one-twelfth of the former maximum. Just as trade was, in the war period, sinking to the vanishing point, the tariff rates were doubled in hopes of getting increased revenues needed for the war, but in vain.

Many statistics bearing upon tariff history are graphically brought together here. This figure should be carefully studied in connection with the following sections. Observe how invariably in the years following a crisis, the amounts of dutiable imports and of duties collected have diminished, whether the tariff meantime was changed or not.]
§ 5. #The tariff, 1816-1845.# Tho rates had been rising, manufacturers had been making efforts to secure higher rates for protection, even as early as 1803. Effectual exclusion of foreign goods and consequent stimulus to the establishment of manufactures in the eastern states resulted, in the period 1808 and 1815, from the embargoes and the war. On the return of peace imports were resumed on a large scale and the call for a higher tariff was loud. In the revision of 1816, rates in a number of cases were fixed higher than those before the war. Average rates are said to have been about 20 per cent. The rate on both cotton and woolen goods was 25 per cent (and the minimum on cotton goods was a specific rate of 6-1/4 cents a yard). High rates were imposed on pig iron (50 cents a hundred), hammered bar (75 cents a hundred), and rolled bar ($1.50 a hundred, equivalent to about 100 per cent ad valorem). Rates were raised on many other articles. The average ad valorem rates collected in 1821 attained the remarkably high figures of 36 per cent on dutiable goods, and almost 35 per cent on free and dutiable together.
In 1824 in response to the growing sentiment in favor of the so-called "American policy of protection," many rates were still further increased, as those on cotton goods and woolen goods (to 33-1/3 per cent) and some kinds of iron. Cheap wool was now taxed 15 per cent and that valued over 10 cents a pound at 20 per cent (to be 30 per cent after 1826). In 1828, in the "tariff of abominations" which evoked much bitter criticism, the rates on all these goods were again raised, those on woolen goods being in some cases 100 per cent on the value, and those on iron being from 40 to 100 per cent on the value, and duties were levied on molasses, hemp, and flax. The results appear in the statistics of 1830, showing the average ad valorem rates on dutiable imports to be nearly 49 per cent, and on free and dutiable together to be over 45 per cent. This marks a temporary high point in tariff rates. Revenues were then becoming excessive and that year the rates on tea and coffee and some other goods were reduced.
