🚨Three Deadlines Hit This Month — and One of Them Is Today

This week's signal: Three deadlines are barreling toward DTC operators at once. USPS drops its first-ever fuel surcharge on April 26. Shopify locks Scripts editing today. And CBP's tariff refund portal is expected to go live any day now. Meanwhile, Prime Day just got moved up to June, and Google quietly added cart support to the protocol that will define how AI agents shop. A lot is happening fast. Let's get into it.

1. USPS Just Broke Its Own Rule: 8% Fuel Surcharge Hits April 26

For decades, USPS bragged that it didn't charge fuel surcharges. They even ran ads about it. That era ended March 25 when USPS filed for an 8% surcharge on all competitive parcel products, effective April 26 through January 17, 2027. Priority Mail, Priority Mail Express, Ground Advantage, Parcel Select. All of them. The Iran war pushed oil past $100/barrel, and USPS said it could no longer absorb the costs. The agency has also warned it could run out of cash within the year without structural changes.

Here's the math that matters: USPS already raised rates 5-8% in January. Stack the 8% surcharge on top and you're looking at double digit effective increases in under four months. A 1-lb local zone package jumps from roughly $7.30 to $7.88 at retail. FedEx and UPS have had fuel surcharges for years (FedEx is at 5.9% GRI plus $4-6 residential surcharges), but USPS was the affordable fallback. That fallback just got more expensive. Switch to commercial pricing if you haven't. Re-quote USPS Ground Advantage against regional carriers like OnTrac and Veho. Multi-carrier isn't optional anymore.

2. Shopify Scripts Lock Today + B2B Features Hit Every Plan

Two Shopify stories colliding this week, and both need your attention. Today, April 15, Shopify freezes Scripts. No more editing. No more publishing. Your existing Scripts keep running until June 30, then they're gone forever. If your BOGO logic breaks on April 16, you can't fix it. Shopify originally planned to retire Scripts by August 2025 and already extended the deadline once. There won't be another extension. Migrate to Shopify Functions now. Run Shopify's customizations report (Settings > Checkout) to identify what needs rebuilding. Agencies are already booked 4-8 weeks out.

The good news: Shopify dropped B2B features to all paid plans on April 2. Company profiles, up to three custom catalogs with tailored pricing, volume discounts, quantity rules, vaulted credit cards, and payment terms. All native. No plugins. Previously locked behind Shopify Plus at $2,300/month. Shopify says merchants using B2B features see up to 33% more self-serve orders within six months and 4.1x higher reorder frequency versus DTC. If you've been managing wholesale through spreadsheets and email, this is the signal to stop.

3. Prime Day Is Moving to Late June. Your Prep Timeline Just Shrunk.

Bloomberg reported (and Modern Retail confirmed through two sources) that Amazon is shifting Prime Day from July to late June. Amazon hasn't officially announced dates yet, but the last time it ran a June Prime Day was 2021. The expected window is June 23-26, possibly extending to four days. That gives sellers roughly 10 weeks from today to prepare inventory, advertising, and deal submissions.

What this means in practice: Your AWD inventory deadline is May 27. FBA optimized shipments need to arrive by June 5. Deals must beat the lowest price from the prior 60 days, plus at least 5% off the last 30 days. If you're planning to raise prices before Prime Day to make the discount look deeper, Amazon's pricing algorithm will catch it. Sellers report mixed sentiment about this year. Lower tariff pressure gives more room for promotions, but the timing overlap with Shoptalk Europe (June 9-11) means attention will be split. Plan for June, hope for July, and don't wait for Amazon's official announcement to start.

4. Google UCP Gets Cart Support — and This One Matters More Than It Sounds

Here's an update that's easy to skim past but shouldn't be. Google updated its Universal Commerce Protocol last week with three new features: multi-item cart support, real-time catalog queries, and identity linking for loyalty pricing inside AI agents. Translation: an AI shopping agent can now add three items to a cart at once, check whether they're actually in stock, and apply your member discount, all without you leaving the conversation. That's a real checkout flow, not a demo.

Google also simplified UCP onboarding in Merchant Center. They want more retailers using this, and they want it fast. UCP already has 20+ partners including Shopify, Visa, Mastercard, Walmart, Target, Best Buy, and Adyen. It's live on AI Mode in Google Search and the Gemini app. Shopify's Agentic Storefronts are plugged into it. The roadmap includes post-purchase support for tracking and returns.

Why this should be on your Q2 list: AI referral traffic to retail sites grew 4,700% YoY. AI Overviews now appear on 14% of shopping queries, and when they do, organic CTR drops 61%. But brands cited in those Overviews earn 35% more organic clicks. The retailers adopting UCP now are the ones who'll show up when agents shop. Join the waitlist via Google Merchant Center if you haven't already.

5. The $166B Tariff Refund Portal Goes Live This Month. Here's What You Need Ready.

CBP's CAPE refund system, the portal that will process all IEEPA tariff refund claims, is expected to launch mid-April. It was 63-80% complete as of early March. When it opens, importers will submit claims through ACE (Automated Commercial Environment). $166 billion in collected duties are at stake across 53 million entries from 330,000+ importers. Refunds carry 6% interest for corporate filers. Only the Importer of Record has standing to file, so if you used a freight forwarder, confirm who holds that status.

Meanwhile, the next wave of tariffs is already being built. USTR launched Section 301 investigations targeting 16 economies for manufacturing overcapacity and 60 economies for forced labor violations. Hearings run April 28 through May 1, with new tariffs potentially ready by July 24, timed to replace Section 122 as it expires. The Trump-Xi summit was pushed to May 14-15. De minimis is still dead. And the 10% Section 122 surcharge runs until July 24 unless Congress acts. Talk to your customs broker now and compile your entry summaries before the portal opens.
