9902.01.54 - Sodium sulfide (CAS No. 1313-82-2) (provided for in subheading 2830.10.00)

This HTS chapter, 9902, and specifically subheading 9902.01.54, pertains to temporary modifications and special provisions related to the importation of specific chemicals. In this instance, it designates Sodium Sulfide (CAS No. 1313-82-2) for special tariff treatment, indicating that its classification may be subject to temporary adjustments or restrictions separate from its standard tariff treatment under Chapter 28. This provision is enacted under Section 22 of the Agricultural Adjustment Act, as amended, or other trade agreement legislation, suggesting its use may be tied to agricultural policy or specific trade agreements.

Unlike the primary HTS chapters that classify goods based on their inherent nature and composition (e.g., Chapter 28 for inorganic chemicals), Chapter 99 is reserved for temporary measures and exceptions. Therefore, 9902.01.54 does not represent a distinct product category in the same way that siblings such as "Live horses" or "Live bovine animals" do. Instead, it acts as a modifier or an overlay on an existing classification, which in this case is provided for under subheading 2830.10.00, governing inorganic sulfur compounds. The function of this 9902 subheading is to signal that the importer must adhere to specific, potentially time-limited, rules or duties beyond the standard classification.

As this is a leaf node, there are no further subcategories within 9902.01.54. This means that any importation of Sodium Sulfide falling under this special provision will be subject to the exact requirements outlined for this specific subheading. Importers should consult the relevant U.S. Customs and Border Protection (CBP) rulings and directives associated with this HTS code to ensure full compliance with any temporary duties, quotas, or other import restrictions that may be in place.
