Date of issuance of ruling:

This is in response to a request submitted on your behalf by Eurofret Canada Inc. for an advance ruling on the tariff classification of an Amplified Controller, Product #LA4X. This product is manufactured by/exported from L-Acoustics Inc., Oxnard, CA, USA.

TRS Number: 275443
Classification Number: 8518.40.90.00

Product Description

According to the documentation provided, the product is an audio-frequency electric amplified controller based on a four input by four output architecture combining the benefits of the self-powered speaker packages with the flexibility of outboard DSP and amplification. The controller can efficiently operate as a conventional amplified controller driving speakers in parallel from its four amplification channels with the added benefit of the 4 inputs when casing passive loudspeaker enclosures. The dimensions of the product are 3.5” (H) X 19” (W) X 16.5” (D).

Analysis and Justification

With respect to Heading 85.18 and its attending Explanatory Note (EN) under (D), the product corresponds to the definition of audio-frequency electric amplifier, since it is:

“… used for the amplification of electrical signals of frequencies falling within the range of the human ear. The great majority are based on transistors or integrated circuits [...]. They are generally powered by a built-in power pack which may be fed from the mains [...]. The input signals to audio-frequency amplifiers may be derived from a microphone, a laser optical disc reader, a pick-up cartridge, a magnetic tape head, a radio feeder unit, a film sound track head or some other source of audio-frequency electric signals. Generally speaking, the output is fed into a loudspeaker [...]. Audio-frequency amplifiers may contain a volume control for varying the gain of the amplifier, and also commonly incorporate controls (bass boost, treble lift, etc.) for varying their frequency response.”


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 product at issue, being an audio-frequency electric amplified controller corresponding to the definition of an audio-frequency electric amplifier, is classified in 8518.40.90.00 of the Customs Tariff by virtue of General Interpretative Rules 1 and 6.
