Proprietary Charging Methods over USB Type-C is Prohibited Mandate: Required Effective Date: July, 2016 As stated in section 4.8.2 of the USB Type-C specification, products implementing proprietary charging methods are not eligible for certification. Section 4.8.2 of the USB Type-C specification is restated below.
4.8.2 Non-USB Charging Methods A product (Source and/or Sink) with a USB Type-C connector shall only employ signaling methods defined in USB specifications to negotiate power over its USB Type-C connector(s). |

Gen 1 USB Type-C to USB Type-C must use an Emarker Mandate: Required Effective Date: January, 2017 Table 3-1 of the USB Type-C Specification states that a Gen 1 USB Type-C to USB Type-C cable must implement an Emarker. The initial certifications of Gen 1 USB Type-C to USB Type-C did not require Emarkers as Emarkers were not readily available in the market place. Now that Emarkers are readily available, the USB-IF is enforcing the requirement that Gen 1 USB Type-C to USB Type-C cables must implement an Emarker. |

USB Automotive Product Certification Requirements Mandate: Required Effective Date: July, 2018 All USB Type-C Car Chargers seeking certification, as well as automotive specific USB products which are directly connected to a 12V car battery (such as a cigarette lighter charger), must be tested at 3 different input voltages to simulate the wide range of input voltages that occur in an automotive setting. These voltages are 9V, 12.5V and 16V. This means that the compliance program must be run 3 times, 1 per input voltage. Automotive specific USB products designed for use with regulated voltage sources are only required to pass at their defined input voltage. At this time the USB-IF defines a USB Car Charger as a USB peripheral which interfaces specifically with a cigarette lighter receptacle.

USB Type-C Power Banks Certification Requirements Mandate: Required Effective Date: April, 2022 A USB Type-C Power Bank is defined as an end-product rechargeable battery containing one or more USB Type-CŪ ports used only for the purposes of sourcing and sinking power. The Table below summarizes the requirements surrounding USB Type-C Power Bank configurations:
Power Banks seeking USB-IF certification must adhere to the following requirements:
These requirements are defined to decrease user confusion by eliminating unnecessary configurations, such as a power bank with multiple USB Type-C Sink-only ports or a power bank that mixes multiple DRPs with source-only capable ports. |

Complex Product Connect Timing Relaxation Mandate: Informational Effective Date: August, 2023 USB-IF allows complex products to take additional time to Connect (Connect refers to the USB defined electrical state). The USB 2.0 specification defines a maximum connection time of 1 second. This is extended up to 5 seconds for products that the USB-IF determines are complex products. During this 5 second period, products are allowed to pull up to 500mA. This includes both USB 3.2 capable products and USB 2.0 capable products. To determine if your product is considered by the USB-IF as a complex product please email techadmin@usb.org. |
