7306.30.50 - Other

Sub-classifications

Commodity Code
Description

Overview

This HTS category, 7306.30.50, encompasses a broad range of "other" welded tubes, pipes, and hollow profiles made of iron or non-alloy steel, specifically those of circular cross-section with a wall thickness of 1.65 mm or more. It serves as a residual category for welded circular pipes and tubes that do not meet the specific criteria of other more granular subheadings within 7306.30.

Distinguishing this category from its sibling, 7306.30.30.00, is crucial. The sibling category is specifically designated for "tapered steel pipes and tubes principally used as parts of illuminating articles." Therefore, 7306.30.50 covers all other welded circular pipes and tubes of the specified wall thickness, irrespective of their end-use or shape, as long as they are not tapered and primarily for illuminating article components.

Within this category, further subdivisions are necessary to refine the classification based on manufacturing processes and specific applications. The subcategories differentiate based on whether the articles are suitable for specialized use in boilers, superheaters, heat exchangers, condensers, refining furnaces, and feedwater heaters, whether cold-drawn, or are otherwise cold-drawn or cold-rolled (cold-reduced) with specific wall thickness limitations. This granular approach ensures accurate tariff application based on the precise manufacturing method and intended industrial function of these iron and steel articles.
