3606.10.00.00 - Liquid or liquefied-gas fuels in containers of a kind used for filling or refilling cigarette or similar lighters and of a capacity not exceeding 300 cm3

This HTS category, 3606.10.00.00, specifically covers liquid or liquefied-gas fuels intended for use in filling or refilling cigarette lighters and similar devices. Crucially, these fuels must be presented in containers with a capacity not exceeding 300 cubic centimeters. This precise specification ensures that only portable fuel sources designed for personal ignition devices fall under this classification. Examples include butane or isobutane sold in small aerosol cans or refill canisters for lighters.

This classification is distinct from its sibling category, 3606.90, which pertains to "Other" combustible materials not meeting the specific criteria of 3606.10.00.00. While 3606.90 would encompass other articles of combustible materials mentioned in Note 2 to Chapter 36 or other forms of pyrophoric alloys, it does not include the specifically defined lighter fuels in small containers. Therefore, the key differentiator is the product's intended use and its packaging size.

As 3606.10.00.00 is a leaf node within the HTS, it does not have further subcategories. Classification is determined solely by the presence of liquid or liquefied-gas fuels packaged in containers of 300 cm³ or less, specifically for lighter refills. Items that are fuels but are not in containers of this specific size or are not intended for lighters would be classified elsewhere, likely under 3606.90 or other appropriate headings depending on their composition and presentation.
