Every Merch on Demand seller knows the feeling: you spend hours on a design, write the listing, hit publish — and 48 hours later it comes back rejected. No clear reason. Just a vague policy reference and one more strike of doubt hanging over your account.

Here's the truth most sellers learn the expensive way: the majority of rejections aren't about your artwork. They're about your words.

After hundreds of uploads, rejections, and resubmissions across a live MBA catalog, we've compiled the full compliance ruleset Amazon enforces but never fully documents. Bookmark this page — it's your pre-upload checklist.

Part 1: The Forbidden Words List

These words trigger rejections or suppressions even when used innocently. Remove them from titles, brands, bullets, and descriptions:

Quality & marketing claims

authentic — implies official licensing
original — same problem, flagged constantly
premium — unverifiable quality claim
best — superiority claim
guaranteed — Amazon makes no guarantees on your behalf

Material & effect claims (the sneaky ones)

neon — your shirt ink is not neon; this is a false product claim
glow — implies glow-in-the-dark ink that doesn't exist
glitter — implies physical glitter
gold / golden — implies metallic material (use "yellow" or describe the design instead)

Filler phrases that flag listings

"perfect for..."
"great for..."

These two phrases are in half the rejected listings we've audited. Describe the design and the audience instead: "Birthday design for 7 year old dirt bike riders" beats "perfect gift for boys."

The title trap nobody tells you about

Never put "Shirt," "Tee," or "T-Shirt" in your title. Amazon automatically appends the product type to every listing. If you write it yourself, your live title reads "Motocross Drip Shirt T-Shirt" — duplicated, unprofessional, and a signal of a low-effort listing.

The bullet you must NOT write

Amazon auto-generates this bullet on every apparel listing:

"Lightweight, Classic fit, Double-needle sleeve and bottom hem"

If you include it manually, it appears twice. You only get two custom bullets — don't waste one duplicating boilerplate.

Part 2: The Hard Specs (Memorize These)

| Field | Limit | Notes | |---|---|---| | Title | ≤ 60 characters | Product type auto-appended — don't add it | | Brand | ≤ 50 characters | Must not infringe existing brands | | Bullet points | ≤ 256 characters each | Exactly 2 custom bullets | | Description | 75 – 2,000 characters | Under 75 = rejection |

Most "mystery rejections" are simply a title at 63 characters or a description at 68. Count before you publish.

Part 3: The Trademark Minefield

This is where accounts die — not rejections, but strikes and terminations. The rule is simple: if an organization can sue, assume it's protected.

Never use:

League names: NFL, NHL, MLB, NBA, FIFA
Event names: Super Bowl, World Series, Stanley Cup, World Cup, Olympics, Grand Prix, Supercross
Motorsport brands: F1, Formula 1, KTM, Honda, Yamaha, Kawasaki
Sponsor brands: Monster Energy, Red Bull
Entertainment IP: Disney, Marvel, Pokémon
Team names, player names, song lyrics
Official crests, federation logos, trophy silhouettes
Sponsor trade dress (a swoosh shape, three parallel stripes)

Safe generic alternatives that buyers actually search:

| Risky | Safe | |---|---| | F1 / Grand Prix | racing, motorsport | | NFL | football | | NHL / Stanley Cup | ice hockey | | MLB | baseball | | FIFA / World Cup | soccer, football tournament, [Country] fan | | Supercross | motocross, dirt bike |

The good news: generic keywords often have more total search volume than the trademarked terms, because Amazon suppresses trademarked searches in POD results anyway. You're not sacrificing traffic — you're capturing the traffic that actually converts on MBA.

Part 4: The Pre-Upload Checklist

Run every listing through this before you hit publish:

☐ Title ≤ 60 chars, no "Shirt/Tee/T-Shirt"
☐ Brand ≤ 50 chars, no existing brand names
☐ 2 bullets, ≤ 256 chars each, no auto-bullet duplicate
☐ Description 75–2,000 chars
☐ Zero forbidden words (scan the list above)
☐ Zero trademarks — leagues, events, brands, players, lyrics
☐ No "perfect for / great for"
☐ Design itself: no logos, crests, trophy shapes, or trade dress

Five minutes of checking saves a 48-hour rejection cycle — and protects the account you spent years tiering up.

The Bigger Picture

Compliance isn't bureaucracy — it's a competitive moat. Most sellers lose listings, slots, and eventually accounts to preventable word choices. The sellers who systematize compliance keep compounding while everyone else restarts from Tier 10.

Validate your niches before you design, and check your listings before you publish. That's the boring 20% of the work that protects 100% of the business.
