    Detailed information for HTS Code 7306.30.50

    AI Summary

    This tariff code falls within Chapter 73 of the Harmonized Tariff Schedule, which covers articles of iron or steel. Specifically, code 7306.30.50 covers welded pipes and tubes of circular cross-section, made of iron or non-alloy steel, with a wall thickness of 1.65 mm or more. Numerous subdivisions exist, qualifying these pipes and tubes further based on diameter, galvanization, whether they are drawn, or their intended use, like electrical conduit or for redrawing; select the most accurate suffix based on these specific characteristics. Remember to consider any applicable U.S. Notes regarding fittings for conducting liquids or gases when classifying these articles.
