9902.04.03 - l-Lysine hydrate (1:1) (CAS No. 39665-12-8) (provided for in subheading 2922.41.00)

This HTS classification, specifically 9902.04.03, pertains to l-Lysine hydrate (1:1), identified by CAS Number 39665-12-8. This provision is designated for temporary legislation and additional import restrictions, acting as a modification or special rule applied to a primary classification. The goods under this subheading are subject to specific import conditions beyond standard tariff treatment, as outlined by Section 22 of the Agricultural Adjustment Act.

Distinguishing this category from its numerous siblings within the broader HTS structure is crucial. While other HTS chapters, such as Chapter 01 (Live Animals) or Chapter 29 (Organic Chemicals), cover distinct product groups based on fundamental characteristics like biological origin or chemical structure, this Chapter 99 provision represents a regulatory overlay. It does not define a primary product category itself but rather modifies the treatment of a product that would otherwise be classified elsewhere, in this instance, under subheading 2922.41.00. The inclusion here signifies a temporary trade policy measure or a specific import restriction applied to l-Lysine hydrate.

As this is a leaf node, there are no further subcategories within 9902.04.03. The classification is definitive for l-Lysine hydrate (1:1) under the specified temporary legislation. Therefore, the practical classification criteria revolve around verifying the identity of the imported product as l-Lysine hydrate (1:1) and ensuring compliance with any accompanying restrictions or requirements dictated by this specific Chapter 99 provision and its underlying legal framework.
