9902.15.13 - Ingots of germanium, unwrought, each weighing 0.5 kg or more but less than 2 kg (provided for in subheading 8112.92.60).

This HTS code, 9902.15.13, specifically designates unwrought ingots of germanium that fall within a defined weight range. These ingots must weigh 0.5 kg or more but less than 2 kg. The classification explicitly states that these items are provided for under subheading 8112.92.60, indicating that their primary material composition and unwrought state are key determinative factors. This temporary provision is located within Chapter 99, which encompasses temporary legislation and modifications related to trade agreements and agricultural adjustments.

Distinguishing this category from its siblings within the broader HTS system is crucial for accurate classification. While other chapters might cover metals or specific materials, Chapter 99 is reserved for special provisions and temporary measures. Within Chapter 99, the 9902 series often relates to specific temporary tariff modifications. Therefore, 9902.15.13 is not to be confused with permanent classifications for germanium or other metals found in earlier chapters of the HTS. Its existence signifies a specific, time-limited trade policy or restriction related to these particular germanium ingots.

As this is a leaf node within the HTS database, there are no further subcategories. The classification is precise, covering only unwrought germanium ingots within the specified weight parameters. Therefore, any germanium ingots outside this precise weight range, or those that are processed or worked, would fall under different HTS classifications, likely within Chapter 81 where unwrought germanium is generally classified if not subject to the specific temporary measures of Chapter 99. The definitive aspect of this classification lies in the combination of material (germanium), form (unwrought ingots), weight (0.5 kg to less than 2 kg), and its placement under a temporary provision.
