Explanatory notes of 7304

The products of this heading include, in particular, line pipes of a kind used for oil or gas,
casing, tubing and drill pipes of a kind used in drilling for oil or gas, tubes and pipes suitable for
use in boilers, superheaters, beat exchangers, condensers, refining furnaces, feedwater heaters
for power stations, galvanised or black tubes ( so-called gas tubes) for high or medium pressure
steam, or gas or water distribution in buildings, as well as tubes for water or gas street
distribution mains. In addition tubes and pipes are used for the manufacture of parts for
automobiles or for machinery, of rings for ball bearings, cylindrical, tapered or needle bearings

AI Summary

Classify pipes used for soil testing under HTS heading 7304 'other' subheadings 7304.39 7304.49 or 7304.59 If the pipes are used for soil testing and not for oil or gas drilling, they do not fall under the subheadings for 'casing, tubing and drill pipe of a kind used in drilling for oil or gas.' Classification should instead be under the 'other' items of heading 7304, the exact subheading depending on material and manufacturing (stainless steel, non-alloy iron/steel, other alloy) and whether they are cold-drawn/cold-rolled. Determine tariff code by confirming composition and processing (e.g., 7304.39/7304.49/7304.59 or the relevant 'other' provision).
