HTS heading 7201 covers pig iron and spiegeleisen presented in pigs, blocks, or other primary forms. These are basic iron-based materials made by smelting, rather than finished articles or shaped steel products. “Pig iron” generally refers to crude iron with a relatively high carbon content; “spiegeleisen” is a ferromanganese iron material with specified manganese and carbon characteristics. The physical form alone does not determine the classification.
To reach the correct 8-digit HTSUS code, first confirm that the product belongs in heading 7201, then narrow it using the applicable subheading distinctions. These distinctions commonly depend on the material’s composition or type, such as whether it is pig iron or spiegeleisen and the relevant manganese, carbon, silicon, or other specification. Review the product’s chemical analysis, manufacturing description, and commercial documents. The 8-digit code combines the international Harmonized System classification with U.S. statistical detail, so the final digits must be verified against the current HTSUS and its legal notes.
What to check
- Obtain a laboratory certificate or mill specification showing the product’s chemical composition, including carbon, manganese, silicon, and other stated elements.
- Confirm whether the material is pig iron or spiegeleisen, and document how the producer defines and manufactures it.
- Verify that the goods are still in primary forms such as pigs or blocks, rather than castings, semifinished products, scrap, or finished articles classified elsewhere.
- Read the heading, subheading text, and relevant Section XV and Chapter 72 notes together; do not classify from the product name alone.
- Check the current HTSUS statistical suffix and seek a customs broker or binding ruling when the composition, form, or product description is borderline.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
