This chemical compound is subject to temporary legislation and import restrictions under Chapter 99 of the Harmonized Tariff Schedule. Its classification is directly tied to its provision under subheading 2904.10.32, indicating it is a specific organic compound and its import is governed by special provisions beyond standard tariff treatments.

Importers encountering this classification should be aware that the "99" chapter signifies a departure from routine tariff schedules. The inclusion of Lithium p-styrenesulfonate under this specific code suggests that its import may be subject to quotas, special licensing requirements, or specific documentation beyond standard customs declarations.
