USB 3.0 Cable
A USB 3.0 cable is a type of cable used for connecting devices for data transfer and power supply, adhering to the USB 3.0 standard. It represents a significant advancement over its predecessors (USB 1.0, 2.0) in terms of speed and efficiency.
Material
USB 3.0 cables typically consist of four core wires shielded within an outer jacket.
- Conductors: Copper is the primary material used for the internal wires due to its excellent conductivity. Higher-quality cables may use thicker gauge copper wiring for improved power delivery and signal stability.
- Shielding: Aluminum foil and/or braided shielding (often copper or aluminum) are used to protect the internal wires from electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring reliable data transfer.
- Insulation: PVC (Polyvinyl Chloride) is commonly used for insulating the individual wires.
- Outer Jacket: PVC or TPE (Thermoplastic Elastomer) are common materials for the cable jacket, providing flexibility and durability.
- Connectors: Typically gold-plated connectors are used for corrosion resistance and improved signal conductivity. The connector housing is usually made of plastic.
Purpose
The primary purposes of a USB 3.0 cable are:
- Data Transfer: Transferring data between a host device (e.g., computer) and a peripheral device (e.g., external hard drive, smartphone, printer).
- Power Delivery: Providing power to peripheral devices, allowing them to operate or charge. USB 3.0 supports higher power output than earlier USB standards.
- Video Transmission: Some USB 3.0 cables (specifically those supporting DisplayPort Alternate Mode) can transmit video signals.
Function
USB 3.0 achieves its increased speed and functionality through several key features:
- Dual-Bus System: USB 3.0 utilizes a dual-bus system, maintaining compatibility with USB 2.0 while simultaneously providing a separate high-speed bus for USB 3.0 devices.
- SuperSpeed Data Transfer: The standard provides a theoretical maximum transfer rate of 5 Gbit/s (625 MB/s), significantly faster than USB 2.0's 480 Mbit/s. Real-world speeds are often lower due to overhead and device limitations.
- Improved Power Management: USB 3.0 allows for higher power delivery (up to 900 mA) compared to USB 2.0, enabling faster charging and operation of power-hungry devices.
- Full-Duplex Communication: USB 3.0 supports full-duplex communication, meaning data can be sent and received simultaneously, further improving transfer speeds.
Usage Scenarios
- Connecting External Hard Drives: Transferring large files quickly and efficiently.
- Connecting SSDs: Utilizing the fast transfer speeds of external Solid State Drives.
- Connecting Cameras: Transferring high-resolution photos and videos.
- Connecting Smartphones and Tablets: Charging devices and transferring data.
- Connecting Printers and Scanners: Faster data transfer for print jobs and scans.
- Connecting VR Headsets: Providing the necessary bandwidth for virtual reality experiences.
- Connecting External GPUs: Transferring video data for enhanced graphics performance.
Common Types
- USB Type-A to Type-A: Connects two devices with Type-A ports (e.g., computer to external hard drive).
- USB Type-A to Type-B: Connects a computer to a printer or scanner.
- USB Type-A to Micro-B: Connects a computer to older smartphones, tablets, and external hard drives.
- USB Type-A to USB-C: Connects a computer to devices with USB-C ports. Very common for charging and data transfer.
- USB Type-C to Type-C: Connects two devices with USB-C ports. Increasingly common for newer devices.
- USB Type-C to Lightning: Connects Apple devices (iPhones, iPads) to devices with USB-C ports.
The declared goods, a USB 3.0 cable, fall under the category of insulated electric conductors, potentially fitted with connectors. Here's a breakdown of relevant HS codes based on the provided information:
- 8544421000: This HS code covers insulated wire, cable (including coaxial cable), and other insulated electric conductors, whether or not fitted with connectors; optical fiber cables, made up of individually sheathed fibers, whether or not assembled with electric conductors or fitted with connectors: Other electric conductors, for a voltage not exceeding
1,000 V : Fitted with connectors: Fitted with modular telephone connectors. While specifically mentioning modular telephone connectors, this code broadly applies to electric conductors with connectors and a voltage not exceeding 1,000V, which a USB 3.0 cable likely meets. The tax rate details are: Basic tariff: 0.0%, Additional tariff: 25.0%, Post-April 2, 2025, additional tariff: 30.0%, resulting in a total tariff of 55.0%. - 8544422000: This HS code covers the same category as above, but specifies "Other: Of a kind used for telecommunications". USB cables are frequently used for data transfer and communication between devices, potentially classifying them under this code. The tax rate details are: Basic tariff: 0.0%, Additional tariff: 25.0%, Post-April 2, 2025, additional tariff: 30.0%, resulting in a total tariff of 55.0%.
- 3926909987: This HS code covers Other articles of plastics and articles of other materials of headings 3901 to 3914: Other: Other Rigid tubes or pipes suitable for use as electrical conduit. While USB cables are not rigid tubes or pipes, the outer sheath of the cable is often made of plastic. The tax rate details are: Basic tariff: 5.3%, Additional tariff: 7.5%, Post-April 2, 2025, additional tariff: 30.0%, resulting in a total tariff of 42.8%.
It is important to note that the final HS code classification depends on the specific characteristics of the USB 3.0 cable (e.g., its primary use, materials, and construction).
