Date of issuance of ruling:

This is in response to your request for an advance ruling on the tariff classification of SPX Copes-Vulcan Multiple Nozzle Spray Desuperheater. This product is manufactured by SPX Flow of McKean, PA, USA.

TRS Number: 274795
Classification Number: 8404.10.00.90
Effective Date:

Product Description

The goods are multiple nozzle spray desuperheaters. The unit is a nozzle tube assembly made from stainless steel alloy. The unit consists of a cage-guided plug situated within a nozzle tube just behind the discharge nozzles. The plug is controlled by an actuator under the signals of a temperature controller.

The function of the unit is to cool process steam by passing a controlled amount of cooling water through the nozzle tube assembly when the plug is extended. The resulting soft, misty spray acts as a cooling medium in the superheated steam flow. The nozzle tube assembly fits up into the bore of the mounting flange and is locked in place with a threaded ring. The unit is used in conjunction with two Heat Recovery Steam Generator (HRSG) cogeneration units.

Analysis and Justification

Heading 84.04 provides for “Auxiliary plant for use with boilers of heading 84.02 or 84.03 (for example, economizers, super-heaters, soot removers, as recoverers); condensers for steam or other vapour power units”. As per the Explanatory Notes (ENs) to heading 84.04, Part (A) Auxiliary plant for use with boilers of heading 84.02 or 84.03, these include: …(4) De-super-heaters. These are used to prevent the development of too high a temperature in the super-heaters. Normally, they are placed between two sections of the super-heater, and generally consist of a cast iron body into which the steam is passed and cooled by a flow of water.


Section 10 of the Customs Tariff directs that classification of imported goods shall be determined in accordance with the General Rules for the Interpretation of the Harmonized System. Section 11 of the Customs Tariff states that in interpreting the headings and subheadings, regard shall be had to the World Customs Organization's (WCO) Explanatory Notes to the Harmonized Commodity Description and Coding System.

General Interpretative Rule 1 (GIR 1) directs that titles of Sections, Chapters and sub-Chapters are provided for ease of reference only. For legal purposes, classification shall be determined according to the terms of the heading and any relative Section and Chapter Notes. Similarly, General Interpretative Rule 6 (GIR 6) directs that classification shall be determined according to the terms of those subheadings and any related Subheading Notes.

The SPX Copes-Vulcan multiple nozzle spray Desuperheater is classified under 8404.10.00.90 in accordance with General Interpretative Rules 1 and 6.
