7506.10 - Of nickel, not alloyed:

This HTS category, 7506.10, specifically classifies nickel plates, sheets, strip, and foil that are composed of *unalloyed* nickel. This means the material primarily consists of nickel with minimal or no other metallic elements intentionally added to alter its properties. These forms of nickel are typically produced through rolling or other metalworking processes and can vary in thickness and width.

Distinguishing this category from its sibling, 7506.20, is crucial. While both cover nickel plates, sheets, strip, and foil, 7506.10 is exclusively for products made from pure, unalloyed nickel. In contrast, 7506.20 pertains to similar forms but made from nickel *alloys*, which contain significant additions of other metals like copper, iron, or chromium to achieve enhanced characteristics such as increased strength, corrosion resistance, or heat tolerance. The presence and proportion of these alloying elements are the defining factor for classification under 7506.20.

Within this category for unalloyed nickel, further distinctions are made at the subcategory level based on physical dimensions. Subcategory 7506.10.05.00 addresses products that do not exceed 0.15 mm in thickness, often referred to as foil. The subsequent "Other" subcategory would encompass all unalloyed nickel plates, sheets, and strip that are thicker than 0.15 mm, allowing for a more precise classification based on the specific form and dimensions of the imported or exported goods.
