Good morning, sellers! Welcome to March 9, 2026’s edition of your daily Amazon briefing.
Today we’re covering FBA Commingling ending March 31, 2026, critical policy updates, fresh opportunities in Dietary Supplements, and the compliance changes you need to know before they hit your account. Let’s dive in…
Data timestamp: March 9, 2026, 9:42 AM ET
1. TOP STORY OF THE DAY
What happened:
Amazon reiterated that Commingling practices (a.k.a. stickerless commingling / using “exact product matches” across sellers to fulfill faster) will end effective March 31, 2026. (sellercentral.amazon.com)
Why it matters:
- Counterfeit + “used sold as new” exposure shifts—you lose the “network speed” upside of commingling, but also reduce the risk that another seller’s inventory gets fulfilled under your listing and triggers returns/negative feedback that your brand eats. (sellercentral.amazon.com)
- Prep + labeling costs become structural, not optional—if you were leaning on stickerless workflows, you now need to treat unit labeling consistency as a margin line item and a receiving-risk lever. (sellercentral.amazon.com)
- Inbound planning impact—any listing-level barcode/prep setting mismatches create inbound friction right when Amazon is already pushing sellers toward more distributed inbound via Inbound placement options. (sellercentral.amazon.com)
Expert take:
Amazon is pricing and designing the network around controllable inputs—clean labeling, predictable cartons, and distributed inbound. Ending Commingling is less about “seller fairness” and more about reducing exception handling (problem-solving units) while tightening traceability when something goes wrong (returns, safety complaints, authenticity claims). (sellercentral.amazon.com)
Action items:
- Do now (today): Pull a list of any ASINs still configured for stickerless/commingled workflows and identify what must be labeled at the unit level going forward (FNSKU vs manufacturer barcode). If you can’t verify the correct setting quickly—pause new inbound for that ASIN until you can. (sellercentral.amazon.com)
- Do now (this week): For top 20% revenue SKUs, run a small inbound test shipment using your intended post-commingling labeling workflow—confirm receiving/FC transfer time doesn’t spike. Window: before March 31, 2026. (sellercentral.amazon.com)
- Hedge: If you rely on stickerless to save labor, price in your new per-unit label + labor cost and re-check your break-even ACOS before you keep bids where they are.

2. AMAZON POLICY & PROGRAM UPDATES
A) Selling Policies & Terms
- Seller Forum report: sellers are flagging invoice rejection timing inconsistency for product authenticity—a poster cites Amazon policy allowing invoices issued within 365 days prior to the violation, but reports rejection based on an earlier cutoff. Status: Forum report—treat as a warning that enforcement/review may be inconsistent. Action: tighten invoice packs (matching legal entity, address, itemized SKUs, and dates) and be ready to escalate via Account Health. (sellercentral.amazon.com)
- Seller-fulfilled refund process—Amazon forum announcement reminder: claims must be submitted within 60 calendar days of the refund being charged (or receipt of returned item for a free replacement) in cases where Amazon has not issued an RFS through Amazon’s prepaid return label program. If you miss the window—you lose the claim. (sellercentral.amazon.com)
B) FBA & Fulfillment
- Inbound placement options—Amazon continues positioning Amazon-optimized shipment splits as the $0 fee option, with minimal shipment splits carrying a fee for sending inventory to fewer locations. Sellers should be checking the estimated placement fee before approving shipment plans. (sellercentral.amazon.com)
- FBA prep/label services removal (US inbound)—still being actively discussed as an operational failure point two months in. If your workflow assumed Amazon would label/prep, you now own the defect chain (labeling, carton content accuracy, prep sufficiency). (emplicit.co)
C) Advertising & Marketing
Unavailable (last 24–48 hours): No verifiable Amazon Ads official announcement surfaced in the last 48 hours via the sources pulled today. (If you want this section fully populated daily, you’ll need a dedicated crawl of Amazon Ads release notes/console messages—today’s web pull did not return a fresh official change within 48 hours.)
D) Compliance & Safety
- FDA issued a March 3, 2026 enforcement action warning 30 telehealth companies about illegal marketing of compounded GLP‑1s—this is not an Amazon-specific policy change, but it’s a signal that FDA scrutiny of medical/weight-loss claims is active right now. If you sell adjacent supplement SKUs, tighten claims and imagery to avoid “drug-like” positioning. (fda.gov)
- Dietary Supplements—credible industry coverage reports Amazon enforcement beginning March 31, 2026 targeting ingredient/weight/potency claims on PDPs that don’t align with the Supplement Facts Panel (SFP), risking listing deactivation. Treat as imminent for any supplement catalog with “equivalent” potency language. (ppc.land)
E) Payments & Financial
Unavailable (last 24–48 hours): No confirmed Seller Wallet, reserve, or disbursement schedule change surfaced in the last 48 hours in today’s pull.
2A. FALSE ALARMS & NOISE FILTER
What’s circulating but NOT verified:
- “FBA inbound placement fees jumped overnight / new penalty fees”
- Status: Monitoring (mostly forum anecdotes; no fresh official rate-card change located in the last 48 hours). (reddit.com)
- Why it matters if true: A $0.40/unit surprise on large-standard can erase 8–15% net margins fast at scale. (reddit.com)
- What we actually know: Amazon’s Inbound placement options structure (free optimized splits vs paid minimal splits) is confirmed; seller reports indicate teams are missing the estimated fee at shipment-plan approval. (sellercentral.amazon.com)
3. MARKETPLACE OPPORTUNITIES & THREATS (verified)
Threat: Dietary Supplements—March 31 listing deactivations tied to label mismatch
Setup: Enforcement starting March 31, 2026 targets PDP ingredient claims that don’t match the Supplement Facts Panel (name, weight, potency representation). (ppc.land)
Math: If a hero ASIN does 20 units/day at $29.99 with 15% contribution margin, a 14-day deactivation is roughly 280 units lost → $8,397 top-line → about $1,259 contribution margin gone—before ranking decay and PPC relearning.
Who this fits: Any seller with supplements using: “raw herb equivalent,” “potency equivalent,” or claims that differ between images, bullets, and A+.
Window: March 31, 2026 (miss it → risk deactivation). (ppc.land)
Execute:
- Export all supplement ASIN copy (title, bullets, A+, backend attributes) and compare line-by-line to the SFP (exact numbers, serving size basis).
- Replace/strip any “equivalent” claims that are not printed on the label.
- Update images to include a clear SFP shot if missing, then re-index via flat file where needed.

4. TOOLS, SOFTWARE & AUTOMATION UPDATES
Unavailable (last 24–48 hours): No verified >20% pricing changes or workflow-impact tool releases affecting Amazon seller operations surfaced in today’s pull.
5. ADVERTISING & PPC INSIGHTS (verified + actionable)
- PPC risk-control move for March: If you’re in Dietary Supplements, temporarily cap bids on ASINs that are label-claim risky until your SFP/PDP audit is complete—because a deactivation turns spend into pure waste and can spike account scrutiny. (Compliance-driven budget protection derived from the March 31 enforcement reporting.) (ppc.land)
ROI impact: Prevents paying CPCs to build demand on an ASIN that may go dark. - Operational PPC tie-in: Before scaling Sponsored Products on SKUs with frequent inbound replenishment, validate your shipment plans are using Amazon-optimized shipment splits when possible—placement fees can silently raise unit economics and distort “true ACOS” vs contribution margin. (sellercentral.amazon.com)
ROI impact: Restores margin headroom without touching CVR.
6. INTERNATIONAL & CROSS-BORDER
Unavailable (last 24–48 hours): No verified marketplace launch, VAT/GST change, or cross-border logistics program update surfaced in today’s pull.
7. SELLER COMMUNITY PULSE
Pattern recognition from forums:
- Early warning signals: Sellers reporting invoice/authenticity outcomes that don’t match their understanding of Amazon’s stated invoice timing requirements—suggesting higher variance in review outcomes. (sellercentral.amazon.com)
- Workarounds in action: Community advice trending toward escalating through Account Health rather than frontline support when stuck in loops (especially for policy decisions). (reddit.com)
- Mistake patterns: Sellers approving shipment plans without checking estimated placement fees—then discovering per-unit hits after the fact. (reddit.com)
Practical Q&A (repeated theme):
“My inbound placement fees look insane—what do I check first?” → Check the shipment plan screen for whether you selected minimal shipment splits vs Amazon-optimized shipment splits, then re-plan with more split locations if your packaging/cartons can support it. If you can’t operationally split, treat the placement fee as a per-unit COGS add and reprice/rebid accordingly. (sellercentral.amazon.com)
8. COMPLIANCE & ACCOUNT HEALTH ALERTS
- Deadline: March 31, 2026—Dietary Supplements PDP claims must match Supplement Facts Panel or risk listing deactivation. Consequence: ASIN suppression/deactivation and revenue interruption. (ppc.land)
- Operational compliance: FBA Commingling ends March 31, 2026—if your inbound workflow still assumes stickerless commingling, you risk inbound friction, mislabeling, and downstream authenticity/customer experience issues. (sellercentral.amazon.com)
- Returns claims control: Seller-fulfilled refunds—submit claims within 60 calendar days or lose recovery eligibility. (sellercentral.amazon.com)
9. DEALS, EXITS & ACQUISITIONS
Unavailable (last 24–48 hours): No verified Amazon-operator M&A/aggregator deal data surfaced in today’s pull.
10. LOOKING AHEAD
- March 25, 2026: Amazon Lists/Wishlists change—third-party sellers fulfilling list purchases may receive full shipping addresses; not a Seller Central policy, but it can raise buyer sensitivity around third-party fulfillment visibility and potential support contacts. Monitor for message volume changes and privacy-related complaints. (404media.co)
- March 31, 2026: FBA Commingling end date—finalize labeling SOPs and audit barcode preferences before this hits receiving. (sellercentral.amazon.com)
- March 31, 2026: Dietary Supplements enforcement start—finish catalog audit before end-of-month. (ppc.land)
11. KEY METRICS SNAPSHOT (when available)
Unavailable (last 7 days): No fresh, citable category CPC benchmarks or ACOS averages were published in the last 7 days in the sources pulled today.
Actionable substitute metric (today): Your own “true ACOS” should be recalculated for any SKU affected by inbound placement fees by adding the per-unit fee to COGS before evaluating bid changes. (Structure confirmed; SKU-specific fee depends on your shipment plan.) (sellercentral.amazon.com)
CLOSING
Tomorrow’s Watch List:
- Any additional official clarification in Seller Forums on Commingling end-state workflows and barcode requirements. (sellercentral.amazon.com)
- Any Seller Central follow-up notices expanding Dietary Supplements enforcement detail beyond the March 31 date. (ppc.land)
- More forum evidence on invoice/authenticity rejection patterns (consistency, timelines, and escalation outcomes). (sellercentral.amazon.com)
Question of the Day:
Which 10 ASINs would hurt you most if they were deactivated for 14 days—and are those the first 10 you’ve audited against the Supplement Facts Panel / label claims?
Quick Win:
Audit 5 supplement ASINs for label-claim mismatches (title/bullets/A+/images vs Supplement Facts Panel) → reduce March 31 deactivation risk → Seller Central > Manage All Inventory (edit detail pages) + your label/SFP source file. (ppc.land)
