At the SITC level, ruling style and page count do not change the classification of a paper exercise book. However, at the HTS 10-digit level, distinctions such as whether the book is ruled or unruled, or whether it meets specific dimension thresholds, can determine the applicable tariff line. Importers should verify the precise HTS subheading against their product specifications before filing entry.

Demand for exercise books peaks sharply ahead of the academic year — typically July through September in the US market. Importers should place orders well in advance to account for production lead times, ocean transit, and potential port congestion that historically intensifies during back-to-school import surges. Holding safety stock or diversifying across multiple suppliers can mitigate supply disruption risk during this window.
