RE: AMREP; Phonic Wheel Simulator; PWS02; Automotive Anti-Lock Break Testing Equipment; Measuring or Checking Instruments; HQ 953382; HQ 089391; HQ 087498; United States v. Corning Glass Works; Functional Unit

Dear Ms. Crawford:

This is in reply to your letter of December 8, 1992, requesting classification of the Phonic Wheel Simulator ("PWS02"), under the Harmonized Tariff Schedule of the United States (HTSUS). Your request has been forwarded to this office for reply.

FACTS:

The "Phonic Wheel Simulator" is described as a fiber optic system used to simulate the magnetic flux generated by a phonic wheel on a sensor (e.g., ABS systems, speed and RPM detectors) in order to simulate how anti-skid automotive systems behave under hazardous electromagnetic conditions. This system allows a dynamic test to be performed on ABS systems without actually turning any parts.

The PWS02 system, which will be imported as a functional unit, contains the following units: 1) mainframe control unit; 2) OSMO2B plug-in four channel base unit(s); 3) a maximum of four OSMO2S satellite units (one for each of the OSMO2B channels); 4) SCU sensor coupling unit; 5) FCmmm monofiber optical cables (mmm is the cable length in meters); and 6) CB1 OSMO2S battery charger.

The stimulation signal is a sinusoidal waveform generated by the PWS02. The frequency of the waveform is completely selectable by the user. Although these machines do not actually perform any measurements or checking themselves, they are required for certain measuring and checking applications.

ISSUE:

Is the PWS02 testing system classifiable under subheading 8543.20.00, HTSUS, which provides for "[e]lectrical machines n.s.p.f...; [s]ignal generators," or is it properly classifiable under subheading 9031.80.00, HTSUS, which provides for: "[m]easuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter: [o]ther instruments, appliances and machines"?

LAW AND ANALYSIS:

The General Rules of Interpretation (GRI's) to the HTSUS govern the classification of goods in the tariff schedule. GRI 1 states, in pertinent part:

...classification shall be determined according to the terms of the headings and any relative section or chapter notes...

There is no controversy that the PWS02 is used exclusively for measuring or checking automotive ABS systems. Furthermore, although these instruments do not actually perform any measurements themselves, they are required for certain measuring or checking applications.

Subheading 9031.80.00, HTSUS, provides for: "[m]easuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter: [o]ther instruments, appliances and machines." The question before us is whether the instant merchandise is classifiable in heading 9031, HTSUS, since it is used in the process of measuring or checking, but does not actually perform the measuring or checking operation.

In HQ 089391, dated February 6, 1992, and HQ 087498, dated October 9, 1990, Customs has held that equipment which is principally used in the process of measuring or checking is classifiable under that provision, even if it does not actually perform the measuring or checking operation itself. See United States v. Corning Glass Works, 66 CCPA 25, 586 F.2d 822 (1978), in which the court stated that the provision for "checking instruments" clearly and unambiguously encompasses machines that carry out steps in a process for inspecting.

Similarly, HQ 087498, held that pursuant to GRI 3(a), a chapter 90 chemical analysis machine heading provides more specifically for merchandise than does heading 8543, HTSUS, which is a general provision for electrical machines not provided for more specifically elsewhere.

Additionally, HQ 953382, dated April 15, 1993, held that a "Power Current Generator" and a "Line Impedance Stabilization Network" were classifiable as apparatus for measuring or checking, even though those instruments did not actually perform the measuring and checking.

Therefore, heading 9031, HTSUS, provides more specifically for the instant merchandise than does heading 8543, HTSUS.

The Legal Notes to section XVI provide guidance for the classification of functional units. Legal Note 4 states as follows:

Where a machine (including a combination of machines) consists of individual components (whether separate or interconnected by piping, by transmission devices, by electric cables or by other devices) intended to contribute together to a clearly defined function covered by one of the headings in chapter 84 or chapter 85, then the whole falls to be classified in the heading appropriate to that function.

Chapter 90, Legal Note 3, states: "[t]he provisions of note 4 to section XVI apply also to this chapter." Clearly, the instant importation is a machine or combination of machines intended to contribute together to the clearly defined function of measuring or checking.

HOLDING:

The AMREP Phonic Wheel Simulator ("PWS02") is classifiable in subheading 9031.80.00, HTSUS, which provides for: "[m]easuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter: [o]ther instruments, appliances and machines." The General rate of duty is 4.9% ad valorem.

Sincerely,

John Durant, Director
