RE: The tariff classification of the Pinnacle Pigging System from
Canada
Dear Ms. Lasher:
In your letter dated June 2, 1994 on behalf of Hydro Kleen
Systems, Inc. you requested a tariff classification ruling.
The Pinnacle Pigging System is a mobile, self-contained,
closed-loop mechanical system used to remove coke and scale from
the inner surfaces of pipes in furnace combustion chambers. The
system is basically composed of an automated control room, tanks
to hold clean and contaminated water, a pump capable of producing
an operation pressure of 100 pounds and a flow rate of 200 gallons
per minute, a 400 horsepower diesel engine, and pigs. All of this
equipment is mounted on a trailer 45 feet in length.
In radiant and convection furnaces coking forms a heavy
buildup in several locations in the pipes, particularly at hot
spots and the exits of the radiation system. This causes reduced
furnace efficiency and is also potentially dangerous. The pigging
process utilizes specially designed pigs made of abrasive materials
for removal of the scale without damaging the pipe surface. The
pigs are inserted into the pipeline by means of a launcher, and as
they travel through the pipes they scrape off any carbon, iron
sulfides, or other material buildups.
The applicable subheading for the Pinnacle Pigging System will
be 8479.89.9099, Harmonized Tariff Schedule of the United States
(HTS), which provides for machines and mechanical appliances having
individual functions, not specified or included elsewhere...: other
machines and mechanical appliances: other: other: other: other.
The rate of duty will be 3.7 percent ad valorem.
This ruling is being issued under the provisions of Section
177 of the Customs Regulations (19 C.F.R. 177).
A copy of this ruling letter should be attached to the entry
documents filed at the time this merchandise is imported. If the
documents have been filed without a copy, this ruling should be
brought to the attention of the Customs officer handling the
transaction.
Sincerely,
Jean F. Maguire
