This is one of a series of Tariff Information Surveys prepared by the United States Tariff Commission and transmitted to the Committee on Ways and Means. The series covers all of the articles and commodities provided for in the tariff act of October 3, 1913, and others not specifically provided for. It is arranged in the numerical order of paragraphs of that act. In some cases two or more paragraphs have been combined in one pamphlet. In doing this industrial relationship of the articles has been followed when possible. In those instances where a paragraph has been treated under a preceding paragraph of the tariff act, reference is made to this fact at the point where the paragraph appears in numerical order. Where one grade of an article is dutiable and another grade of the same article is on the free list, the article is discussed under the dutiable paragraph, which appears first in numerical order in the tariff act. In certain instances articles of close industrial relationship and which occur in separate paragraphs of the tariff act have been combined under one paragraph for convenience of discussion. Reference is made to this fact at the point where the commodities would naturally occur in numerical order. The first pamphlet in the series is an "Introduction and Index," which contains: 1. An introductory chapter discussing the scope of the series and the general method of treatment. 2. An alphabetical index of the articles provided for in the tariff act of 1913, showing the paragraph of the act in which the article is provided for and, if discussed under a different paragraph, the number of such paragraph. 3. A list of the pamphlets in the series, showing the paragraphs and articles included in each pamphlet. Thus, by use of this "Introduction and Index" the exact location of the discussion relating to a given article or commodity can be ascertained. In the preparation of this report, the Tariff Commission had the services of Paul M. Tyler, of the metals division, and Dr. Grinnell Jones, C. R. DeLong, and Sidney D. Kirkpatrick, of the chemical division, of the Commission's staff, and of others. 3 |
