Direct answer: is PD 3.1 certification over?
For new end products, yes — the window for certifying to USB PD R3.1 has closed in 2026. USB-IF grants grace periods for end products based on each revision’s publication date: 24 months for end products and 18 months for silicon. Applied by USB-IF authorised test laboratories, that schedule puts the closure of USB PD R3.1 V1.8 in September 2026, and USB PD R3.2 V1.0 in November 2026. The latest published revision, USB PD R3.2 V1.2, was released 20 May 2026. For B2B buyers, the practical rule is simple: source chargers developed on the USB PD 3.2 certification baseline now, and confirm the exact certificate and revision for the model you are buying.
Why certification timing matters
A USB-IF certificate is not a one-time stamp and it is not generic. Three facts decide whether it helps you:
- It is model-specific. The certificate names an exact model number, not a product family.
- It is revision-specific. A certificate issued against PD R3.1 does not automatically cover PD 3.2 behaviour.
- It is time-bound. 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.
This is why “we are PD 3.2 ready” and “we hold a USB PD 3.2 certification” are two very different statements, and why the USB PD 3.2 certification closure dates below are not trivia.
The USB-IF revision and grace-period model
USB-IF manages the Power Delivery specification through numbered revisions. When a revision is published, it becomes the active baseline, and older revisions are given a wind-down period before new certifications on them stop being accepted.
| Element | Grace period | What it means |
|---|---|---|
| Silicon (controllers, PHY) | ~18 months | Chip vendors must move to the new revision |
| End products (chargers, devices) | ~24 months | New product certifications on that revision stop being accepted |
The dates below are the practical result of that model as applied by authorised laboratories. USB-IF revises them periodically, so always confirm the current schedule with your own test lab before locking production.
The 2026 closure timeline
| Revision | Published | New end-product certification | Status |
|---|---|---|---|
| USB PD R3.1 V1.8 | Prior baseline | Closed September 2026 | No longer accepted for new products |
| USB PD R3.2 V1.0 | October 2023 | Closing November 2026 | Window ending; develop on 3.2 now |
| USB PD R3.2 V1.2 | 20 May 2026 | Active baseline (~24 months) | Current latest revision |

What “R3.1 V1.8 closed” actually means
This is the part most buyers misunderstand:
- You can no longer certify a NEW product to PD R3.1. Fresh end-product submissions on that baseline are no longer accepted.
- Products already certified under PD 3.1 are not recalled. Existing certificates and the products they cover remain valid to sell.
- But new development should be PD 3.2. Any charger you design from now to ship in 2027+ should be built on the R3.2 baseline, or it will hit a certification dead end.
The risk is not today’s shelf stock — it is a 2027 product plan that freezes on a revision nobody can certify by the time you launch.
USB PD R3.2 V1.2: the current baseline
USB PD R3.2 V1.2 (20 May 2026) is the latest published revision. Its headline change — the one that matters for most chargers — is SPR AVS (Adjustable Voltage Supply) in the 27W–100W band, making AVS mandatory above 27W. Maximum power stays at 240W (EPR); what changes is efficiency and heat in the mid-power range that serves most of the market.
For buyers, a product “designed to USB PD 3.2 including SPR AVS” is the right baseline. Whether a specific SKU also carries a fresh certificate on that revision is a separate, model-by-model question — and the honest answer is that it varies.
The EU angle: common charger and IEC 62680
The European Union reinforces the direction with Directive (EU) 2022/2380 on the common charger, which mandates USB Type-C and references the IEC 62680 series. The relevant standard is IEC 62680-1-2:2024, the IEC edition of USB Power Delivery Specification Revision 3.2, Version 1.0.
For EU-bound chargers, the practical path is a Type-C PD design aligned to the current IEC 62680 edition. PD 3.2 is the specification that edition expresses, so the certification and the regulation are pointing the same way.
What B2B buyers should do now
Here is a short action list for anyone sourcing chargers that need USB PD 3.2 certification in 2026 or 2027.
- Specify PD 3.2 as the baseline for new projects. Do not open a 2027 product on an R3.1 frozen design.
- Ask for the exact certificate, not a claim. Request the PDF naming your model number and the revision it was tested against.
- Confirm the revision, not just the brand. “USB-IF certified” without a revision and model number is not verifiable.
- Plan the transition. If you carry PD 3.1-certified stock, sell it through; design replacements on PD 3.2.
- Watch the November 2026 window. R3.2 V1.0 closes then; new work should target V1.2 or later.
Red flags when a supplier talks about PD 3.2
- A certificate that names a different model than the one you are buying.
- A claim of “PD 3.2 ready” with no model-specific test report.
- A certificate dated to R3.1 presented as current.
- Reluctance to send the PDF file (a screenshot is not proof).
None of these means the product is bad. They mean the evidence is missing, and for a compliance-sensitive market that gap is the risk.

Frequently asked questions about USB PD 3.2 certification
When does USB PD 3.1 certification end?
For new end products, the window closed in September 2026. 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.
Is USB PD 3.1 dead?
No — 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.
What is the difference between R3.1 V1.8 and R3.2 V1.0 / V1.2?
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.
What grace period does USB-IF give?
About 24 months for end products and 18 months for silicon, counted from each revision’s publication. The exact closure dates are set by authorised labs and revised periodically.
Does the EU common charger directive require PD 3.2?
Not by name, but it points the same way. Directive (EU) 2022/2380 mandates USB Type-C and references IEC 62680-1-2:2024, the IEC edition of USB PD R3.2 V1.0.
Should I only buy PD 3.2 certified chargers now?
For new product development, yes. Source on the PD 3.2 baseline so your 2027 launch is certifiable; continue selling any PD 3.1-certified stock you already hold.
Can I still sell products certified under PD 3.1?
Yes. Existing certificates and the products they cover remain valid; only new certifications on that revision have stopped.
How do I verify a supplier’s PD 3.2 certificate?
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.
Are Paiyi Power chargers certified to PD 3.2?
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. We send the current certificate and test report for the specific model you are buying rather than making a blanket claim.
Conclusion
The PD 3.1 certification window has closed for new products, and PD 3.2 V1.0 closes in November 2026. The lesson for B2B buyers is not panic about shelf stock — it is to make sure every 2027 product plan is built on the PD 3.2 baseline, with a real, model-specific certificate behind it.
Specifications move. Certificates are what prove you moved with them. Ask for the document, not the adjective.
