7309.00.00.30 - Tanks

This HTS classification, 7309.00.00.30, specifically designates tanks and similar containers, constructed from iron or steel, designed for the storage of materials other than compressed or liquefied gases. The critical defining characteristic for inclusion in this subcategory is a capacity exceeding 300 liters. These containers may be lined or heat-insulated, but they must not be fitted with any mechanical or thermal equipment, which would place them in a different classification.

This category is distinguished from its sibling, 7309.00.00.90, which covers "Other" tanks and reservoirs of iron or steel. The distinction lies in the explicit exclusion of containers designed for compressed or liquefied gases within this specific subcategory. Furthermore, the 300-liter capacity threshold is a key differentiator; smaller containers would likely fall under different HTS headings.

As this is a leaf node in the HTS database, there are no further subcategories under 7309.00.00.30. Therefore, the focus for classification within this code is on the material (iron or steel), the intended purpose (storage of non-gaseous materials), the capacity (over 300 liters), and the absence of integrated mechanical or thermal equipment. Examples could include large industrial storage tanks for liquids like water, chemicals (excluding compressed/liquefied gases), or bulk materials, as well as agricultural water tanks or fermentation vats meeting the specified criteria.
