What is the HTS code for lighter fuel refills?
Liquid or liquefied-gas fuels in containers of a kind used for filling or refilling cigarette or similar lighters, of a capacity not exceeding 300 cm3, are classified under 3606.10.00.00. The general (MFN) rate for that line is Free.
What is the duty on ferrocerium flints?
Ferrocerium and other pyrophoric alloys are classified under 3606.90.30.00. The general (MFN) rate for that line is 5.9%.
How do I classify hexamine solid fuel tablets?
They are not a lighter fuel or a pyrophoric alloy, so they fall in the residual line for other combustible articles under 3606.90.80.00. The general (MFN) rate for that line is 5%.
