About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS subcategory, 8483.40.30.40, specifically covers fixed ratio speed changers that are imported for use with machinery designed for the production of cellulosic pulp, paper, or paperboard. These devices are integral components in the manufacturing processes of these materials, providing a consistent and predetermined alteration of rotational speed between input and output shafts. They are designed to operate within the specific mechanical demands and operational environments of paper and pulp production machinery.

This classification distinguishes itself from its sibling category, 8483.40.30.80 (Other), by its specific end-use application. While 8483.40.30.80 would encompass fixed ratio speed changers not intended for paper or pulp manufacturing machinery, this category is narrowly defined by its intended function within that particular industry. Therefore, the critical distinguishing factor for classification here is the documented purpose of the speed changer as being for integration into cellulosic pulp, paper, or paperboard making equipment.

As this is a leaf node within the HTS, there are no further subdivisions. Classification at this level hinges on the precise determination that the imported fixed ratio speed changer is intended for, and will be utilized with, machinery engaged in the manufacturing of cellulosic pulp, paper, or paperboard. Documentation supporting this intended use is essential for correct classification.
