Date of issuance of ruling:

This is in response to a request submitted on your behalf by GHY for an advance ruling on the tariff classification of Dog & Bone Backbone Battery. This product is manufactured by Dog & Bone Cases, Brisbane, Queensland, Australia.

TRS Number: 276894
Classification Number: 8507.80.90.00
Effective Date:

Product Description

The good is the Backbone Battery for use with the Backbone iPhone SE/5s/5 case. The good is a 900mAh lithium polymer battery which slides into a Dog & Bone iPhone case. The battery is charged via micro USB port and charges an iPhone via the phone's lightning port. It can be charged separately or while connected to an iPhone. The battery charges the iPhone when slid into the case and connected to the phone.

Analysis and Justification

Heading 85.04 covers static converters. Regard is given to the Explanatory Note to heading 85.04, Part (II), which states that the apparatus of this group are used to convert electrical energy in order to adapt it for further use through incorporation of converting elements of different types. As the good at issue does not adapt electricity for further use, no further consideration is given to this heading.

The next heading to be considered is heading 85.29, as it covers parts suitable for use solely or principally with the apparatus of headings 85.25 to 85.28. Regard is given to Exclusion (c) to the Explanatory Note to heading 85.29, which excludes accumulators for mobile phones.

Heading 85.07 is then considered, as it covers accumulators. Rechargeable batteries are accumulators. Regard is given to the Explanatory Notes to this heading which states:

Accumulators containing one or more cells and the circuitry to interconnect the cells amongst themselves, often referred to as "battery packs", are covered by this heading, whether or not they include any ancillary components which contribute to the accumulator's function of storing and supplying energy, or protect it from damage, such as electrical connectors, temperature control devices (e.g., thermistors), circuit protection devices, and protective housings.


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 Dog & Bone Backbone Batteries, being lithium-polymer rechargeable batteries for use with Backbone iPhone SE/5s/5 cases, are classified under 8507.80.90.00, as other accumulators in accordance with General Interpretative Rules 1 and 6.
