Mixed frozen fruit preparations are generally classified based on the essential character of the blend or, if no single component dominates, may fall under a residual or mixed-preparation heading. If the blend contains fruits that each have their own specific SITC heading (e.g., strawberries), the classification may depend on which component predominates by weight or value. For complex blends, a binding ruling from CBP is advisable to avoid misclassification.

Frozen nuts are relatively uncommon in trade compared to dried or roasted nuts, but they do appear — particularly in food-service supply chains where freshness and texture are priorities. The key distinction from other nut headings is the frozen preservation state; nuts that are roasted, salted, or otherwise prepared fall under prepared/preserved nut categories. Freezing alone, without further preparation, keeps nuts within this heading.
