Crosslist from Mercari to Etsy — Which Half of Your Catalogue Is Even Allowed
Etsy takes handmade, vintage and craft supplies, and nothing else. Before you map a single field, work out how much of your Mercari catalogue clears the twenty-year line — and learn the three fields Etsy demands that Mercari has never captured.
- Most of a Mercari catalogue is not eligible for Etsy, and that is the whole story. Etsy allows handmade items, vintage items and craft supplies. Modern used clothing, phones, consoles and sneakers are none of those things.
- Vintage means made in 2006 or earlier — a hard 20-year line that moves every January. “Vintage-inspired” and reproductions do not count.
- Craft supplies are the overlooked win. They qualify at any age, so destashed fabric, yarn, beads, buttons, patterns and tools port cleanly even though nothing else in the same closet does.
- Etsy requires three fields Mercari has never captured — who made it, what it is, and when it was made. A crosslister has nothing to map them from; you assert them, and asserting them wrongly is the violation.
- Mercari charges sellers again. The “zero selling fees” headline is out of date: fees returned on 6 January 2025, not “ahead of 2026” as several guides still claim.
- Cost: from £9/month. There is no free plan, but every new account gets a 7-day free trial.

First, the uncomfortable part
Every crosslisting tool on the market presents Etsy as one more destination tile beside eBay and Poshmark. The marketing copy usually describes it accurately, in one line, as a marketplace for handmade and vintage goods — and then the interface invites you to push your whole catalogue at it.
That framing costs sellers their shops. Etsy permits exactly three things: items you made, items at least twenty years old, and craft supplies. A general resale catalogue is none of those. Etsy’s own guidance on reselling is blunt about the consequence, describing termination of the account along with the loss of existing inventory, sales history and reviews.
So the first question is not how to map a size field. It is how much of your catalogue is allowed through the door. For a typical Mercari seller the honest answer is: a minority of it, and possibly none — Mercari is deliberately a general marketplace, and its own investor material describes the platform as one where users buy and sell anything rather than leaning toward a specific category (Mercari investor FAQ).
That is not a reason to skip Etsy. Etsy reported 86.6 million active buyers and $2.5 billion of gross merchandise sales in the first quarter of 2026 (ValueAddedResource, Etsy Q1 2026 earnings), while Mercari’s US segment has been losing monthly active users even as its GMV grows (ValueAddedResource, Mercari US). If you hold genuine vintage or craft supplies, moving them onto Etsy is one of the highest-value channel additions available. You just have to know which items those are before you start.
Triage your catalogue in one pass
Run every Mercari listing through a single question: was it made in 2006 or earlier, is it a craft supply, or did you significantly transform it yourself? If none of those, it does not go.
| Ports to Etsy | Does not port |
|---|---|
| Clothing and accessories made 2006 or earlier | Modern used clothing from 2007 onward — the bulk of Mercari fashion |
| Vintage homeware, glassware, ceramics, furniture | Phones, consoles, games and other modern electronics |
| Collectibles, ephemera, postcards, paper goods over twenty years old | Modern toys, sneakers, streetwear, beauty products |
| Craft supplies at any age — fabric, yarn, beads, buttons, patterns, tools | New-in-box retail goods, wholesale buys, dropshipped stock |
| Vintage jewellery | Modern secondhand household goods |
| Items you refurbished or upcycled yourself | Electronics refurbished by somebody else |
The craft-supply row is the one most sellers miss. Craft supplies carry no age requirement at all, so a Mercari seller who lists destashed sewing and knitting materials has a fully eligible product line sitting inside an otherwise ineligible catalogue. If you have been treating that stock as filler, it is the part to move first.
The trading-card and collectibles stock that Mercari’s US business increasingly leans on is worth a second look too, since a meaningful slice of it clears the twenty-year line on age alone.
One timing note worth checking before you commit inventory: Etsy has announced further tightening of its creativity and originality rules through 2026, including changes affecting resold supplies and templated designs, and reporting on the August 2026 round indicates real fur loses its vintage exemption entirely (ShieldMyShop, Etsy August 2026 policy changes). We could not confirm that specific change against Etsy’s own policy pages, so treat it as a prompt to check rather than a settled fact — but if vintage fur is a line for you, check it before listing.
The three fields Mercari has never heard of
Assume you have your eligible slice. The mapping problem now looks unlike any other crosslisting route, because Etsy asks for something no other marketplace does.
Etsy’s developer documentation lists the fields a listing cannot publish without: quantity, title, description, price, taxonomy, images, a shipping profile, a readiness state — and who made it, and when it was made (Etsy listing tutorial). Alongside those sits the question of whether the item is a finished product or a craft supply.
| Etsy requires | Mercari holds | What it takes |
|---|---|---|
| Who made it — you, someone else, or a collective | Nothing | You assert it. Vintage means someone else. |
| What it is — finished product or craft supply | Nothing | You assert it. This decides which rulebook applies. |
| When it was made — era or decade | Nothing | You assert it, and vintage demands 2006 or earlier. |
| Thirteen tags, twenty characters each | No tag concept | Written from scratch. Tags are most of Etsy search. |
| Title up to 140 characters, as an SEO surface | Short, functional titles | Expanded. A Mercari title is far too thin to rank. |
| A shipping profile object | Prepaid label chosen at checkout | Created before any listing can publish. |
| Deep category taxonomy plus per-category attributes | Flatter category tree | Full remap; there is no one-to-one. |
| Renewal every four months | Listings persist until removed | An ongoing obligation Mercari does not impose. |
The first three rows are the important ones, and they are the reason this route cannot be fully automated by anybody, us included. Those fields are the exact mechanism Etsy uses to police eligibility. There is no Mercari data to derive them from, so a crosslister that quietly guessed would be manufacturing the evidence Etsy later judges you on. What software should do is force the question once per item, remember the answer, and refuse to publish without it. That is what FLUF Connect does.
Note one asymmetry that works in a vintage seller’s favour: production-partner disclosure applies to handmade goods made with someone else’s help, not to vintage listings. If you are selling twenty-year-old stock, that requirement does not reach you.
Proving something is twenty years old
Etsy can ask where vintage stock came from and how it was sourced, and can request photographs of the indicators you relied on. Sellers who deal in vintage clothing do this with labels rather than intuition, and it is worth learning the three signals that do most of the work.
Care labels. Mandatory care instructions arrived in 1971. A garment with no care label at all is very likely older than that, which puts it comfortably past the twenty-year line.
RN numbers. Registered identification numbers have been issued since 1952. Five-digit RNs generally indicate the 1960s through the 1980s; the numbering restarted in the region of 13670 in 1959, so the digit count alone brackets a garment usefully.
Union labels. ILGWU labels read “ILGWU AFL” until the 1936 split and “ILGWU CIO” afterwards, which can narrow a piece to a window of a decade or two on its own.
The practical rule from vintage dealers is to cross-reference at least three signals, because any single one misleads (Sammy D. Vintage on labels and tags, Vintie+ label guide by decade). Where you have receipts, appraisals or provenance documents, keep them (eRank guide to selling vintage on Etsy).
We should be honest about the gap here. We could not find an Etsy statement setting out an evidentiary standard for age, or a defined route to dispute an age decision. So the sensible posture is not to argue after the fact but to document before listing, and to leave genuinely borderline pieces on Mercari, where nobody is asking.
What each platform actually takes
Correct a widespread error first. Mercari abolished seller fees in March 2024, and reversed that decision nine months later; the current structure took effect on 6 January 2025. Several guides published during 2026 still describe the change as happening “ahead of 2026”, which is a year out.
Mercari’s fee page is unusually clean. Listing is free of charge, the seller pays 10% of the item price plus buyer-paid shipping, the buyer pays a 3.6% protection fee, and payment processing costs neither side anything (Mercari fees, Mercari fee change FAQ). Direct deposit is free and typically takes five to seven business days; Instant Pay costs a flat $3.
Etsy’s cost is not a single number, and that is the real difference. It stacks: a per-listing charge that recurs every four months whether or not the item sells, a transaction percentage applied to shipping as well as the item, payment processing, and — above a trailing-year sales threshold — mandatory Offsite Ads participation that cannot be switched off once triggered.
We are deliberately not reproducing Etsy’s full fee schedule here. Etsy’s fee pages could not be retrieved directly when this page was researched, and publishing a stale percentage would be worse than publishing none. Check the current figures on Etsy’s own fees page before you price anything. Two structural points do not depend on the exact numbers:
| Mercari | Etsy | |
|---|---|---|
| Cost of listing an item that never sells | Nothing | A recurring per-listing charge every four months |
| Shape of the seller cost | A single percentage | Several charges stacked, one of which becomes compulsory with scale |
| Does the fee apply to shipping? | Yes, included in the 10% base | Yes — worth modelling before you absorb postage |
| Time to money | Five to seven business days, no hold | A payout schedule, and new shops can sit behind a reserve |
The last row catches people. Etsy holds buyer payments and releases them on a schedule after identity and banking verification, and applies reserves to newer shops based on trading history, dispute rates and tracking. A Mercari seller accustomed to money landing within a week should expect early Etsy sales to move more slowly, and should not read that as something going wrong.
One pricing trap specific to this pair: Etsy’s transaction fee applies to shipping, and Etsy has given search preference to shops guaranteeing free shipping on US orders over $35 since July 2019 (Etsy investor relations). Porting Mercari prices unchanged and then absorbing postage to chase that placement squeezes you from both ends.
How to crosslist with FLUF Connect
Etsy connects through a standard authorisation you approve once, and everything afterwards runs server to server with nothing left open. Mercari works differently: its listings are driven through your own signed-in Mercari session rather than a server API, so that side is paced deliberately rather than fired all at once.
The workflow that suits this route is not “select all”. It is:
| Step | What happens |
|---|---|
| Import from Mercari | Your listings, photos, prices and descriptions are read into one catalogue. |
| Filter to the eligible slice | Work through the triage above and tag what qualifies. This is the step no tool can do for you. |
| Answer the triplet once per item | Who made it, what it is, when it was made. Stored against the product and reused. |
| Expand titles and write tags | Mercari titles are too short for Etsy search; thirteen tags have no source field. |
| Create a shipping profile | Required before an Etsy listing can publish at all. |
| Publish and keep in step | Stock stays aligned across both, and Etsy relisting is handled for you. |
Etsy listings expire after four months rather than running indefinitely, so relisting is an operational requirement on this channel rather than a growth tactic. It is included in every plan.
What syncs between them
This is one of the better-behaved pairs we support, because both sides report their own sales.
| Event | What happens |
|---|---|
| An item sells on Mercari | Detected automatically, and the Etsy listing is closed. |
| An item sells on Etsy | Detected automatically, and the Mercari listing is dropped. |
| You edit a price or description | Pushed to both. |
| An Etsy listing nears its four-month expiry | Relisting is supported, so the listing does not silently lapse. |
Two-way sale detection matters more here than on most routes, because your Etsy stock is by definition one-of-one. A vintage coat cannot be restocked, so an oversell is not an inconvenience — it is a cancellation on a platform that is already watching your account.
The risk nobody connects to crosslisting
There is a body of writing about Etsy suspensions, and a body of writing about crosslisting to Etsy, and almost nothing joining them. They belong together.
Etsy acts on listings that look commercially available and commonly resold, and sellers report enforcement arriving as an automated message rather than a conversation, sometimes against long-established shops. Appeals for a permanent suspension are, by Etsy’s own process, a one-shot affair, with an investigation window measured in weeks (OneShop on Etsy account suspension).
Bulk-pushing a general resale catalogue at Etsy is precisely the pattern that triggers it. That is the case for doing this route slowly and selectively, and it is why the eligibility section sits at the top of this page instead of the bottom. A crosslisting tool that helps you publish two hundred ineligible listings efficiently has not helped you.
What it costs
FLUF Connect starts at £9/month on Starter, covering 300 products, with Growth at £19/month for 1,000. There is no free plan, though every new account gets 7 days of full access with no card required. Relisting, offers and bulk operations are included in every plan rather than sold separately — which matters here, because Etsy’s four-month expiry makes relisting a standing cost of doing business.

Where a figure could not be traced to the platform that sets it, this page omits it rather than repeating it. Etsy’s active seller count, its current reserve percentages, and the exact new-shop set-up charge all fall into that category.

Frequently Asked Questions
Only if it was made in 2006 or earlier. Etsy allows handmade items, vintage items and craft supplies, and its vintage rule is a hard twenty-year line that moves forward every January. Modern secondhand clothing — the bulk of what sells on Mercari — is not eligible however good its condition, and “vintage-inspired” or reproduction pieces do not qualify either.
A minority of it, and for some sellers none. Mercari is deliberately a general marketplace where people buy and sell anything, while Etsy is restricted to three narrow classes of goods. The parts that usually port are genuine vintage clothing and homeware made 2006 or earlier, collectibles and ephemera over twenty years old, vintage jewellery, anything you significantly transformed yourself, and craft supplies.
Craft supplies, because they carry no age requirement at all. Destashed fabric, yarn, beads, buttons, sewing patterns and tools qualify whatever their age, so a seller with an otherwise ineligible catalogue often has one product line that ports cleanly. If you have been treating that stock as filler on Mercari, it is the sensible thing to move first.
Who made the item, what it is (a finished product or a craft supply), and when it was made. All three are required before a listing can publish, and none of them has any Mercari equivalent, so no crosslisting tool can derive them from your existing data. You assert them yourself. They are also the exact mechanism Etsy uses to police eligibility, which is why asserting them carelessly is the violation rather than a formatting mistake.
By reading labels rather than guessing. Mandatory care instructions began in 1971, so a garment with no care label is very likely older. Registered identification numbers have been issued since 1952, and a five-digit RN generally points to the 1960s through 1980s. ILGWU union labels read “AFL” before the 1936 split and “CIO” after it. Dealers cross-reference at least three signals, because any single one misleads. Keep receipts or appraisals where you have them.
No — that is out of date. Mercari abolished seller fees in March 2024 and reversed the decision nine months later, with the current structure taking effect on 6 January 2025. Sellers now pay 10% of the item price plus buyer-paid shipping, listing remains free of charge, and payment processing costs neither side anything. Several guides published during 2026 still date the reversal to “ahead of 2026”, which is a year out.
Because Etsy's fee pages block automated retrieval, and publishing a stale percentage would be worse than publishing none. What matters structurally is the shape rather than the digits: Mercari takes a single percentage and charges nothing for an item that never sells, whereas Etsy stacks a recurring per-listing charge every four months, a transaction percentage that also applies to shipping, payment processing, and compulsory Offsite Ads participation above a trailing-year sales threshold. Check the current figures on Etsy's own fees page before pricing.
Yes, in both directions. A Mercari sale is detected automatically and the Etsy listing is closed; an Etsy sale is detected automatically and the Mercari listing is dropped. That two-way behaviour matters more on this pair than most, because eligible Etsy stock is one-of-one by definition — a vintage coat cannot be restocked, so an oversell becomes a cancellation on a platform that is already scrutinising your account.
Bulk-pushing a general resale catalogue will put you at real risk. Etsy acts on listings that look commercially available and commonly resold, enforcement often arrives as an automated message rather than a conversation, and an appeal against a permanent suspension can only be filed once. The protection is selectivity: move only the slice that genuinely qualifies, document your vintage dating before listing, and leave borderline pieces on Mercari where nobody is asking.
Yes. An Etsy listing runs for four months and then needs renewing, which is unlike Mercari where a listing persists until you remove it. That makes relisting an operational requirement on this channel rather than an optional growth tactic, and it is a recurring cost even on items that never sell. Relisting is included in every FLUF Connect plan.
