Goods here must be armored or reinforced — constructed with hardened steel, composite armor, or similar materials specifically to resist forced entry, cutting, or fire. A standard sheet-metal lockbox or filing cabinet with a lock does not meet this threshold and would classify under the office equipment or furniture hardware headings.

When an electronic locking mechanism is an integral component of a safe presented as a complete unit, the whole article classifies here. Only separately imported lock components or access panels would be classified on their own merits under the applicable lock or electrical apparatus heading.
