USPS vape-ship ban, which carriers are still legal?

The 2021 PACT Act amendment (signed December 2020, effective April 2021) banned USPS from shipping vape products. Within weeks:

• USPS, banned vape, full stop. No exceptions.
• FedEx Ground, banned consumer vape March 2021.
• UPS Ground, banned consumer vape April 2021.
• DHL, banned vape globally May 2021.

What’s left in 2026:

• FedEx Adult Signature 21+ via specialty broker, FedEx still ships if you go through an approved 3PL broker that handles signature, adult-verification, and PACT Act registration on your behalf. Cost: ~$8, $15 per shipment (vs $4, $7 USPS used to be).
• X-Delivery, vape-specialty carrier, US-only, 5-9 day delivery. Covers most ZIPs east of Mississippi well, sparse west of it.
• GoExpedited, similar to X-Delivery, better West Coast coverage.
• UDS (United Delivery Service), vape-specialty, regional (mostly Midwest + South).
• OnTrac, West Coast regional, covers CA / OR / WA / NV / AZ. Faster than national carriers but limited footprint.

How we wire it in Magento:

• Carrier-select rebuild, auto-remove USPS, FedEx Ground, UPS Ground, DHL at carrier-select for vape carts. Show only legal carriers.
• State-by-state carrier validation, not every legal carrier ships to every state. X-Delivery covers ~40 states; the others fill gaps. Validate ship-state against carrier coverage before showing rates.
• ETA expectation-setting, vape shipping is now 5-9 business days, not 2-3. Surface this on PDP + cart so customers don’t expect Amazon-speed.
• PACT Act registration check, if you ship >1 package/month of vape, you must register with the ATF + each state tax authority. We add admin warnings if registration is missing.
