7307.29.00.30 - Nipples

This HTS classification, 7307.29.00.30, specifically covers "Nipples" made of iron or steel. Nipples are short lengths of pipe, typically threaded at both ends, used to connect two pipes or to connect a pipe to a fitting. Within the broader category of "Other, of stainless steel," this subheading isolates nipples that do not fit into any more specific classifications at this level. The primary defining characteristic here is the form factor and function of a nipple, distinct from other types of stainless steel pipe fittings.

The primary sibling category to consider at this level is 7307.29.00.90, which is also designated as "Other." While both are "Other" at the 8-digit level, the distinction lies in the 10-digit breakdown. Subheading 7307.29.00.30 is specifically for nipples, whereas 7307.29.00.90 would encompass any other stainless steel pipe fittings that are not nipples and do not fall under more specific subheadings. For accurate classification, one must determine if the article's primary function and form align with the definition of a nipple.

As this is a leaf node within the HTS database, there are no further subcategories for this specific classification. Therefore, the focus for classification under 7307.29.00.30 is on correctly identifying articles as "Nipples" made of stainless steel, distinguishing them from other types of pipe fittings, and ensuring they are not classifiable under more specific subheadings within 7307.29.00. The practical application of this subheading requires a precise understanding of the physical characteristics and intended use of the article in question to confirm it meets the definition of a nipple for connection purposes.
