HTS heading 2615 is a four-digit product category for ores and concentrates of niobium (also called columbium), tantalum, vanadium, or zirconium. It groups these mineral materials together because they are unprocessed or concentrated mineral products, rather than refined metals, finished powders, chemicals, or manufactured goods.
To choose the specific 8-digit HTSUS code, first identify which of the four minerals the shipment contains and whether it is an ore or a concentrate. The 8-digit subheading generally separates the products by mineral or material type. Use the product’s technical description, assay or laboratory results, processing records, and applicable HTSUS heading and subheading notes. If the material is a refined compound, metal, or other processed product, heading 2615 may not apply; classification may require customs-broker or specialist judgment.
What to check
- Confirm whether the goods are an ore or concentrate, rather than a refined metal, chemical compound, powder, or finished product.
- Identify the principal mineral—niobium (columbium), tantalum, vanadium, or zirconium—using the commercial description and material assay.
- Review the current HTSUS text, subheading structure, and legal notes before selecting the 8-digit code.
- Match the invoice, packing list, assay, certificate of analysis, and product specifications so they consistently describe the same material.
- Ask a customs broker or request a binding classification ruling when the product contains multiple minerals or its processing level is unclear.

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.

Common questions
What products fall under HTS heading 2615?
Niobium (columbium), tantalum, vanadium or zirconium ores and concentrates. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
