Michael Leightman Ernst & Young, LLP 5 Houston Center, Suite 1200 1401 McKinney Street Houston, TX 77010 RE: Tariff classification of light crude distillation plant Dear Mr. Leightman: This is in response to your letter of February 8, 2019, submitted on behalf of ExxonMobil Oil Corporation (“ExxonMobil”), requesting a prospective ruling as to the classification of a light crude distillation plant (“the plant”) under the Harmonized Tariff Schedule of the United States (“HTSUS”). In reaching the below determination, we have considered information presented in your February 8, 2019 letter (“the February letter”), your response to questions posed by the National Commodity Specialist Division (“NCSD”) dated May 23, 2019 (“the May letter”), your supplemental letter dated June 27, 2019 (“the June letter”), and your response to questions posed by Headquarters dated March 2, 2020 (“the March letter”). FACTS: As detailed in the February, May, and March letters, ExxonMobil intends to import the parts and components of the plant from Thailand, first admitting them into a foreign trade zone (“FTZ”) covering the site of the intended construction. After completing construction of the plant, ExxonMobil plans to enter the completed plant by constructively transferring the plant into the Customs territory, and filing appropriate entry documentation. Therefore, ExxonMobil seeks classification of the final assembled plant, as a whole, not the individual components admitted to the FTZ. According to your February, May and March letters, the completed plant will fractionate light crude into light virgin naphtha (“LVN”), heavy virgin naphtha (“HVN”), kerosene, light gas oil (“LGO”), heavy atmospheric gas oil (“HAGO”), and atmospheric tower bottoms (“ATB”), and will route the streams for further refining within and outside the plant. The plant will consist of assembled units and subunits permanently attached to each other, including fully heat-integrated preheat train, prefractionator tower, desalter, depentanizer, stripper, preheater, condenser, exchanger and compressor, and a cooling water tower. (February letter p. 2 and 5) You state that disconnecting any one unit from the whole would prevent the plant from functioning as designed. (February letter, p. 2). The plant will fractionate and refine the products through a series of distillations and supporting processes. First, the light crude feed is preheated, to segment the crude feed into streams with different approach temperatures. The stream with the lowest approach temperature is mixed with process water, and sent to the desalter, where water, salt and solids are separated from the crude. The desalted crude is then directed through the preheat train, which operates at high pressure to prevent vaporization as the crude is heated. The preheated, desalted crude is then flashed at various cold temperatures into the prefractionator, which is a fractional distillation column operating at low temperature. The offgas of the prefractionator is routed to the overhead drum, see infra. The crude from the bottom of the prefractionator is pumped through the hot preheat train into the Atmospheric Pipestill (“APS”) Furnace to be heated. (February and May letters). The heated crude is then directed into the main APS tower, which is a fractional distillation column that separates the crude into different fractions depending on the difference in volatility. (May and March letters). The four components of the crude with the highest boiling points (ATB, HAGO, LGO, and kerosene) are steam stripped in the APS tower. (May and March letters). The steam-stripped kerosene is next directed to the Kero Hydrotreater Unit (KHDT) for desulphurization. (See infra). The steam-stripped LGO is directed to the Diesel Hydrotreater Unit (DHDT) for desulphurization. (See infra). The steam-stripped ATB and HAGO are not further processed by this facility. (March letter). The components remaining in the crude after these components have been stripped comprise the “overhead” of the APS tower. The liquid overhead is HVN, which is not further processed in this plant. (March letter). The vapor overhead is composed of LVN, steam, and offgas. The vapor overhead is directed to the overhead drum, where it is combined with the vapor overhead of the other fractionation towers. (March letter). In the overhead drum, this mixture is condensed, and water is routed to the desalter for reuse. The overhead drum also condenses part of the offgas into liquid, which is routed to the depentanizer. The depentanizer is a fractional distillation column that further fractionates the liquid from the overhead drum into offgas, depentanizer overhead liquid, and LVN. The remaining vapor in the overhead drum is sent to the compressor suction, where it is mixed with gas streams from the KHDT and DHDT strippers (see infra), Benzene Recovery Unit flash gas (see infra), the depentanizer offgas, and recovered gas from the flare system. The mixture is compressed, contacted with the depentanizer overhead liquid, cooled, and separated into fuel gas and liquefied petroleum gas. Both streams are then amine scrubbed using an amine water solution, which bonds with carbon dioxide (CO2) and hydrogen sulfide (H2S), removing them from the gas products. Kerosene separated from the crude feed by the APS tower is sent to the KHDT unit for desulphurization. In the first step, the kerosene feed from the APS tower is mixed with hydrogen and heated. The heated mixture is then pumped through a reactor containing fixed beds of solid metal catalyst, where the hydrogen reacts with the kerosene feed to produce hydrogen sulfide and desulphurized kerosene. The kerosene feed is then partially cooled, and separated into hydrogen gas and residual liquid in the Hot and Cold Separators. The hydrogen gas is recycled to the first step in the process. The residual liquid is sent to the kero stripper tower, a fractional distillation tower that separates the desulphurized kerosene from sour gases. The product remaining at the bottom of the distillation tower is Sulphur-free diesel. The overhead vapor from the kero stripper tower is sent to the overhead compressor. The overhead liquid from the kero stripper tower is sent to another facility for further processing. The DHDT unit removes Sulphur from LGO, using the same multi-step process. ISSUE: Whether the completed plant is classifiable as a “Distilling or rectifying plant” in subheading 8419.40, HTSUS, or as “other” apparatus for the treatment of materials by a process involving a change of temperature in subheading 8419.89, HTSUS. LAW AND ANALYSIS: Classification under the HTSUS is made in accordance with the General Rules of Interpretation (GRIs) and any applicable legal notes. GRI 1 requires that classification be determined first according to the terms of the headings of the tariff schedule and any relative section or chapter notes. In the event that the goods cannot be classified solely on the basis of GRI 1, and if the heading and legal notes do not otherwise require, the remaining GRIs 2 through 6 may then be applied in order. GRI 6 provides that classification of goods at the subheading level will be determined according to the terms of those subheadings and any related subheading notes and, mutatis mutandis, to the preceding GRIs on the understanding that only subheadings at the same level are comparable. The HTSUS provisions under consideration in the instant case are as follows: 8419 Machinery, plant or laboratory equipment, whether or not electrically heated (excluding furnaces, ovens and other equipment of heading 8514), for the treatment of materials by a process involving a change of temperature such as heating, cooking, roasting, distilling, rectifying, sterilizing, pasteurizing, steaming, drying, evaporating, vaporizing, condensing or cooling, other than
