Three facts decide whether it helps you:<\/p>\n<ul>\n<li><strong>It is model-specific.<\/strong> The certificate names an exact model number, not a product family.<\/li>\n<li><strong>It is revision-specific.<\/strong> A certificate issued against PD R3.1 does not automatically cover PD 3.2 behaviour.<\/li>\n<li><strong>It is time-bound.<\/strong> USB-IF retires acceptance of older revisions on a published schedule, so a design frozen on an old revision eventually cannot be certified at all.<\/li>\n<\/ul>\n<p>This is why &#8220;we are PD 3.2 ready&#8221; and &#8220;we hold a USB PD 3.2 certification&#8221; are two very different statements, and why the USB PD 3.2 certification closure dates below are not trivia.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"the-usb-if-revision-and-grace-period-model\">The USB-IF revision and grace-period model<\/h2>\n<p>USB-IF manages the Power Delivery specification through numbered revisions.

According to USB-IF authorised laboratories, PD R3.1 V1.8 is no longer accepted for new product certifications. New work should move to USB PD 3.2 certification, and R3.2 V1.0 closes in November 2026.\"}},{\"@type\":\"Question\",\"name\":\"Is USB PD 3.1 dead?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No \u2014 existing certificates remain valid. Products already certified under PD 3.1 can still be sold; what ends is the ability to certify new products on that old revision.\"}},{\"@type\":\"Question\",\"name\":\"What is the difference between R3.1 V1.8 and R3.2 V1.0 \/ V1.2?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"R3.2 adds SPR AVS below 100W and is the active baseline; V1.2 (20 May 2026) is the latest. R3.1 V1.8 is the last R3.1 revision and is now closed to new certifications.\"}},{\"@type\":\"Question\",\"name\":\"What grace period does USB-IF give?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"About 24 months for end products and 18 months for silicon, counted from each revision\u2019s publication. The exact closure dates are set by authorised labs and revised periodically.\"}},{\"@type\":\"Question\",\"name\":\"Does the EU common charger directive require PD 3.2?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Not by name, but it points the same way.

Source on the PD 3.2 baseline so your 2027 launch is certifiable; continue selling any PD 3.1-certified stock you already hold.\"}},{\"@type\":\"Question\",\"name\":\"Can I still sell products certified under PD 3.1?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. Existing certificates and the products they cover remain valid; only new certifications on that revision have stopped.\"}},{\"@type\":\"Question\",\"name\":\"How do I verify a supplier\u2019s PD 3.2 certificate?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Ask for the PDF naming your exact model and the revision tested. Confirm the test house is USB-IF accredited, and check the standard edition. A screenshot is not proof.\"}},{\"@type\":\"Question\",\"name\":\"Are Paiyi Power chargers certified to PD 3.2?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Paiyi Power products are designed to the USB PD 3.2 specification including SPR AVS; certification status varies by SKU and production batch, and earlier runs were certified under PD 3.1.
