What does HTS Chapter 26 cover?

Chapter 26 of the U.S. Harmonized Tariff Schedule (HTSUS) covers Ores, slag and ash. It sits within Section V: Mineral Products. Tandom's catalog lists all 102 10-digit statistical lines and 8 4-digit headings in this chapter.

What is the typical U.S. duty rate for Chapter 26 imports?

General (Column 1) duty rates for ad-valorem lines range from 5% to 5% (median 5%); roughly 98% of lines enter duty-free. Use the calculator linked from each code page to build a date- and origin-specific import-duty estimate, including applicable Chapter 99 layers and customs fees. Potential AD/CVD exposure is flagged separately and is not included in the estimate.

How are Section 301 and Section 232 measures represented in the HTSUS?

Section 301 and Section 232 measures are represented by Chapter 99 provisions. A catalog link between a provision and a 10-digit line is a screening flag, not a claim that the measure applies; origin, product and material facts, claims, and entry date control the result.

How do I screen for antidumping or countervailing duty (AD/CVD) when using Chapter 26?

AD/CVD orders are issued at the case level by the Department of Commerce against specific products from specific countries. Use the product's base HTS code to find potentially relevant AD/CVD order flags, then read the written order scope; an HTS match alone does not determine coverage.

Chapter 26: Ores, slag and ash

Chapter 26 of the U.S. Harmonized Tariff Schedule covers Ores, slag and ash and sits within Section V: Mineral Products.

About Chapter 26

Chapter 26 contains 102 10-digit statistical lines grouped under 8 4-digit headings. Brokers, importers, and customs counsel use these codes to declare ores, slag and ash on entry summaries (CBP Form 7501) and to look up the published Column 1, Special, and Column 2 rate notation.

General (Column 1) duty rates for ad-valorem lines in Chapter 26 range from 5% to 5%, with a median of 5%. About 58% of the chapter's lines (59 of 102) enter duty-free under the general rate. Special-rate notation (including USMCA, KORUS, AGOA, and GSP when authorized) and Chapter 99 measures can modify these base rates for qualifying shipments.

Product-code pages link into the Tandom Tariff Calculator with the base HTS code prefilled. Chapter 99 provision pages instead show mapped base codes and send you to a dated calculator scenario, which determines whether a measure applies from the entry facts. Tandom's data refreshes daily from USITC HTSUS, CBP CSMS, the Federal Register, and the Department of Commerce — the same authoritative sources the trade community files against.
