9903.81.84 - Derivative iron or steel products enumerated in note 16(a)(ii) to this subchapter, when such goods are products of Ukraine and are not accompanied by certificates of origin

This HTS category, 9903.81.84, specifically addresses derivative iron or steel products that are enumerated under note 16(a)(ii) of this subchapter. Critically, these goods must be originating from Ukraine. A key defining characteristic for classification under this code is the absence of a valid certificate of origin accompanying the shipment.

Distinguishing this category from its siblings at the Chapter 99 level is crucial for accurate classification. While other Chapter 99 headings might cover temporary legislation or modified import restrictions, 9903.81.84 is uniquely tied to specific derivative iron and steel products from Ukraine without proof of origin. This contrasts with general tariff headings that might cover iron and steel products without such origin-specific or temporary restriction elements.

As this is a leaf node within the HTS database, there are no further subcategories. Therefore, classification under 9903.81.84 is definitive when the criteria of the product type (derivative iron or steel as per note 16(a)(ii)), origin (Ukraine), and documentation (lack of certificate of origin) are all met. Importers should meticulously verify these conditions to ensure correct duty assessment and compliance.
