当你出门忘记关闭电源的时候，心想能否有“人”帮我关？当你想在严热的夏天回家前能否有“人”帮我提前打开空调？家中无人时如果有人入室盗窃能否自动报警？类似的“梦想”可以变成现实了。下面介绍三种帮你实现梦想的家庭网络产品。
商品一：D-Link Wi-Fi智能插座
该智能插座（D-Link Wi-Fi Smart Plug Lite），型号为DSP-W110，有三线柱插头和三孔插座，插座用于控制类似电灯、风扇这样的家用电器。通过手机APP给该插座发送控制信号（或指令），使电路闭合或断开，以打开或关闭电器设备。该插座密封在一塑料外壳内，长3 ½英寸，宽2英寸，厚1 ½英寸，带有三个控制按钮：电源按钮、连接家庭网络的WPS(Wireless Protected Setup)按钮、复位按钮。交流额定电压120V，额定电流15A。智能插座包括开关、继电器、熔断器、触点、插头、插座。如图1所示。

商品二：D-Link Wi-Fi智能插座
该智能插座（D-Link Wi-Fi Smart Plug），型号为DSP-W215，与上一型号的智能插座相比，在造型上、结构上和功能上相似，但存在某些差异：尺寸上稍大些，有两个控制按钮（一个是电源按钮、一个是WPS按钮），内置有温度传感器。如图2所示。

商品三：D-Link Wi-Fi 热释电红外运动传感器
该热释电红外运动传感器（D-Link Wi-Fi Pyroelectric infrared (PIR) Motion Sensor），型号为DCH-S150，是一个有两片插头的电器设备，带有WPS按钮，用于操控智能插座。该传感器用红外波检测26英尺范围内物体的运动，当检测到物体运动时，可将信号发送到用户的手机上。同时它还可发送信号至智能插座上，从而实现所需的功能。该传感器密封在一个塑料壳内，长2英寸，宽2英寸，厚1 ½英寸。交流额定电压120V，额定电流0.1 A。图3为实物图，图4为安装位置图。

三种商品的归类分析
两种智能插座（商品一与商品二）的主要功能通过接受红外运动传感器的指令实现电路的自动闭合或断开，属于电气的控制与分配装置，智能插座本身包括开关、继电器、熔断器、触点、插头、插座，从其结构上判断，由品目85.36的多个装置组成，已不是一个简单的插座，归入品目85.36不妥，应归入品目85.37项下，并根据额定电压归入子目8537.1090；
热释电红外运动传感器（商品三）的主要功能是检测周围物体的运动情况，并给用户手机和智能插座发送指令，从而由手机用户决定下一步的动作。该商品虽有检测功能，但检测功能并不是其主要功能，故归入第九十章不妥；该商品虽属于网络产品，通过家庭网络（Wi-Fi）与手机进行信息交换并操控智能插座，其通信功能并非其主要功能，故归入品目85.17也不妥。该商品为电气设备且所具有的主要功能在《协调制度》的品目条文中未具体列名，所以建议该商品归入品目85.43项下，并根据归类总规则六归入子目8543.7099。

CATEGORY: Classification
TARIFF NO.: 8537.10.9070; 8543.70.4000
RE: The tariff classification of three Wi-Fi-basedhome networking products from Taiwan and China
Dear Mr. Gomez:
In your letter dated July 17, 2014 yourequested a tariff classification ruling on behalf of your client, D-Link Systems,Inc. The samples are being returned as requested.
The merchandise under consideration is the D-Link Wi-Fi Smart Plug Lite, model numberDSP-W110; the D-Link Wi-Fi Smart Plug,model number DSP-W215; and the D-Link Wi-FiPyroelectric infrared (PIR) Motion Sensor, model number DCH-S150,all imported separately from each other.
The D-Link Wi-Fi Smart Plug Lite, model number DSP-W110, is a three-prong plug-in module with a three-plug outlet used forthe insertion and control of various electric devices inside the home,such as a lamp and fan. It is controlled by a mobileapp which sends a signal (or command) to the module, thereby causingits circuit to close or open and turn a device on oroff. The module is encased in a plastic housing, measuring approximately3 ½ inches in length by 2 inches in width and 1 ½ inches in depth, with threecontrol buttons: a power button, a WPS (Wireless Protected Setup) button toconnect to the home network; and a reset button. It is rated for up to 120Volts (V) AC and 15 Amps (A). From the information provided by you, the SmartPlug incorporates switches, relays, fuses, contacts, plugs and sockets. It doesnot have built-in surge protection nor does it contain components that divert avoltage spike to ground.
The D-Link Wi-Fi Smart Plug, model number DSP-W215, is similar to model numberDSP-W110 in styling, construction and function in noting the followingdifferentiating features: it is slightly larger insize; it has two control buttons (a power button and a WPS button); andit has a built-in temperature sensor.
The D-Link Wi-Fi PIR Motion Sensor, model number DCH-S150, is a two-prong plug-in module, with a WPS button, whichoperates with the Smart Plug model numbers DSP-W110 and DSP-W215. The sensor uses infrared waves to detect the motion of anobject within a range of 26 feet and sends a signal to the user’s phone whenmotion is detected. This signal is also transmitted to the SmartPlug(s), thereby directing the desired action. It is encased in a plastichousing measuring approximately 2 inches in length by 2 inches in width by 1 ½inches in depth. It is rated for up to 120 Volts (V) and 0.1 Amps (A).
The applicable subheading for the D-Link W-Fi Smart Plug Lite, model number DSP-W110, and theD-Link Wi-Fi Smart Plug, model number DSP-W215, will be 8537.10.9070,Harmonized Tariff Schedule of the United States (HTSUS), which provides for"Boards, panels, consoles, desks, cabinets and other bases, equipped withtwo or more apparatus of heading 8535 or 8536, for electric control or thedistribution of electricity…: For a voltage not exceeding 1,000 V: Other:Other: Other." The rate of duty will be 2.7 percent ad valorem.
The applicable subheading for the D-Link DCH-S150 PIR Motion Sensor will be 8543.70.4000,HTSUS, which provides for “Electrical machines and apparatus, having individualfunctions, not specified or included elsewhere in this chapter; parts thereof:Other machines and apparatus: Electric synchros and transducers; flight datarecorders; defrosters and demisters with electric resistors for aircraft. The rate of duty is 2.6 ad valorem.
