N300606 · 2018-10-17 — The tariff classification of an agitator from an unspecified country
, you requested a tariff classification ruling. The subject agitator is said to be used solely in drilling operations. The steel alloy downhole tool is designed to reduce any friction caused by the drill pipe making contact with the sides of the borehole wall. It is said to be “generally located above the bottom hole assembly (BHA) 1 (i.e., above the drill bit, but below the first piece of drill pipe)” on the drill string. Utilizing axial vibrations, the agitator reduces the amount of friction. The agitator is not used in well completion or well remediation operations. Upon completion of the…
N254796 · 2014-07-24 — The tariff classification of a stop-collar from Canada or China
, you requested a tariff classification ruling. The stop-collar is described as a steel ring that keeps centralizers and other casing attachments in place while casing and cementing an oil or gas well. Casing and cementing the wellbore are steps in the well drilling process. The article is made from oil country tubular goods (“OCTH”) coupling stock. The stop-collar is affixed to the outside of casing pipe by a series of set screws located along the collar’s circumference, locking pins, or a bolt assembly, depending on the model. The stop-collar is imported with the locking pins, set screws or…
N246814 · 2013-11-15 — The tariff classification of drill pipe, drill collar, square kellys and drill-stem subs from Russian Federation
The products being imported are drill pipe, drill collars, square kellys and drill-stem subs. The drill pipe is seamless, cold-rolled alloy steel. It is made to API 5D specifications. The outside diameter does not exceed 168.3mm and the wall thickness exceeds 9.5mm. The drill pipe is designed to produce axial load onto the rock-destroying tool and to transfer torque from the rotor when drilling complex horizontal wells. The drill collar is intended to produce axial load onto the drill bit and to increase rigidity of the drill string. The square kelly is used to transmit rotation from the…
N199595 · 2012-01-24 — The tariff classification of integral blade stabilizers from China.
The integral blade stabilizers are designed for maximum wear, superior stabilization and optimum drilling and directional control characteristics. These stabilizers have 6.5 outside diameter bodies with a 2.25 inch hole with threads machined in each end for connection. The applicable subheading for the stabilizers will be 8431.43.8060, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Parts suitable for use solely or principally with the machinery of headings 8425 to 8430: of machinery of heading…8430: Parts for boring or sinking machinery of subheading 8430.41 or…
N192544 · 2011-11-16 — The tariff classification of Non-Magnetic Drill Collars from Japan
The merchandise under consideration is non-magnetic drill collars. The non-magnetic drill collars are solely or principally used on oil and gas well drilling machinery. They are sold to both the offshore and onshore drilling industries with anticipation of the majority of sales will be to the offshore drilling industry. Product 1- The steel would be cut into 31 foot lengths and a circular hole would be drilled through the length of the steel to create a non-magnetic steel drill collar. At the time of importation the drill collars meet all the standard of API Specification 7-1¹ except those…
