7310.29.00.55 - Refillable stainless steel kegs, whether or not pressurized, of a kind described in statistical note 1 to this chapter

This HTS category, 7310.29.00.55, specifically covers refillable stainless steel kegs. These containers are designed for storing and transporting various substances, excluding compressed or liquefied gases. The defining characteristic is their material composition (stainless steel) and their refillable nature, often implying a robust construction suitable for repeated use and potential pressurization, as indicated in statistical note 1 to Chapter 73. Their capacity is not exceeding 300 liters, and they are not fitted with mechanical or thermal equipment.

Within the broader classification of "Other" containers of a capacity of less than 50 liters, this specific subheading distinguishes itself by its focus on stainless steel kegs. While sibling categories under 7310.29.00 also fall under "Other," they may encompass a wider range of steel containers not specifically identified as refillable stainless steel kegs. The key differentiator here is the explicit mention of stainless steel and the refillable nature, which suggests specialized applications such as for beverages or other liquids where material integrity and reusability are paramount.

As this subheading is a leaf node, there are no further subdivisions. Therefore, classification into this category relies heavily on meeting the specific criteria of being a refillable stainless steel keg of the described capacity and type, as detailed in the statistical note. Importers and exporters should ensure that the physical characteristics and intended use of their stainless steel kegs precisely match these specifications to ensure correct customs declaration.
