Seller agreement
Kayu lists your wood and passes buyers to you. It takes no payment and no commission, and it is not part of the sale — you and the buyer agree the price, the postage and how they pay. What Kayu asks in return is that your listings are true: real photographs of the actual piece, honest grades, and paperwork that lets the wood travel.

Who this is between
This agreement is between you — the person or business selling — and Kayu, which operates kayushop.eu. Accepting it is a condition of listing here, and your acceptance is recorded with the version, the date and the address you accepted from.
Kayu is an introduction, not a shop. It shows your wood to people looking for it and passes on their enquiries. It does not buy from you, does not sell to them, and is not a party to whatever the two of you agree.
The sale is yours. The contract is between you and the buyer, and every obligation in it — the goods, the description, the paperwork, the postage, and any refund — is yours too.
What Kayu does, and what it does not
It does:
publish your listings and put them in a catalogue people can search
carry a buyer’s enquiry to you with their email address, so you can reply directly
check who you are before granting a verified mark
take listings down, and suspend sellers, when the rules below are broken
It does not:
take the buyer’s money, hold it, or pass it on
charge you a commission or a listing fee at present
refund a buyer, decide a dispute between you, or guarantee your sale
ship anything, or handle customs or export paperwork on your behalf
That is deliberate rather than temporary neglect. A platform that holds other people’s money owes them a great deal, and Kayu is not yet in a position to owe it honestly. Saying so plainly is better than a promise nobody could keep.
Business or private, and why it matters to you
You must tell us which you are, and buyers are shown it before they contact you. It is not a formality: a buyer purchasing from a business has consumer rights that do not apply to a private sale, and saying the wrong one misleads them about what they are entitled to.
A business
A registered company or sole trader. You need to give us your legal entity name, your registered address and your company registration number. If you sell to consumers in the EU, consumer law applies to you: a right to return, and a two-year liability for faults.
A private individual
Someone selling their own stock rather than trading. You need to give us your name and address, and identity we can check — not a company number, which you do not have. Buyers are told consumer protections do not apply.
Be honest about which you are. If you sell regularly and for profit, most tax authorities treat you as trading whether or not you have registered — and at that point consumer law applies to you anyway, retroactively. Listing continuously as a private individual is not a way around that; it is only a way to be surprised by it later.
If you are outside the EU, the practical question is not consumer law — it is that export permits, phytosanitary certificates and due diligence statements are issued to registered businesses. Without one, most of what is worth selling cannot lawfully leave your country. That, rather than anything on this site, is the reason to register.
Getting verified, and what it is worth
You need an account to start, but not much more: an administrator has to verify you before you can list anything yourself. That takes your legal name, your registered address, this agreement accepted, and — if you are a business — your registration number. We will usually also want the registration document itself, or identity for a private seller. Until you are verified, we can list a first piece on your behalf while you finish the paperwork — ask us.
Verification is what makes your shop and your listings visible to a buyer at all — not in the catalogue, not in search, not by a link to your shop page. It used to only affect placement; it is now what opens the door. Once you are verified, a search still answers the buyer’s question first among verified sellers: it does not put your walnut above someone else’s spruce when they searched for spruce.
Everything you upload is visible to Kayu administrators and to nobody else. If your legal identity changes, your status returns to pending until it has been looked at again.
What you may list
Wood you own and hold. Not wood you expect to buy, not a photograph of something similar, and not stock held by someone else on your behalf unless you can actually post it when a buyer asks.
Species listed on CITES Appendix I cannot be listed at all and are refused when you try. For an Appendix II species, the listing stays up but shows “contact seller” instead of a delivery option until you hold a valid permit covering that species. Keeping permits current is yours; an expired permit means the wood should not be moving.
Where the EU Deforestation Regulation applies to what you sell, you are the operator placing it on the market and the due diligence statement is yours to make. We record the reference; we do not make the statement for you.
Describing wood honestly
This is the part Kayu genuinely does control, and the part it will enforce. A buyer is choosing a specific piece of wood from photographs on a screen, and the listing is the only thing standing between them and a stranger abroad.
Photograph the actual piece you are selling. At least 1, of that piece, not of another one like it and not a stock image. More is better — a buyer abroad has nothing else to go on.
Shoot it as it is. Cropping, straightening and honest exposure are fine. Saturation, colour grading, filters and anything that makes the figure look stronger than it is are not.
Show the faults. A knot, a check, sap wood, a colour streak or a repair must be visible in the photographs and mentioned in the description.
Dimensions are optional, but if you give them, give real ones — and give a real quantity. If a set is book-matched, say so. If it is not, do not imply it.
Say how it has been seasoned and for how long, if you know. Buyers building instruments will ask, and “I don’t know” is a better answer than a guess.
Wood varies, and photographs of wood vary more. Nobody expects a screen to match a workshop bench exactly. What is expected is that the piece which arrives is recognisably the piece that was photographed.
What each grade means
Grade is your claim about the whole piece — figure, grain, and freedom from defects together — and it is the claim a disappointed buyer will hold up first. Grade generously against yourself. Figure type and figure intensity are recorded separately; a plain piece can still be AAA.
AAA
Master grade. Quarter-sawn or very close to it, even and tight grain, consistent colour. No knots, checks, pin holes, sap wood or repairs anywhere on the piece. Where the piece is figured, the figure runs across the whole face rather than a part of it. Both halves of a book-matched set match closely.
AA
Excellent, with something small that keeps it off master grade — slight run-out, a little colour variation, figure that fades toward one edge. Structurally perfect: no knots, checks or repairs.
A
Sound, usable wood with visible character. Mineral streaks, uneven colour, a small tight knot away from the critical area, or light or partial figure. Nothing that affects the strength or the working of the piece for its stated purpose.
B
Cosmetically marked but sound and honest. Knots, sap wood, surface checks that do not run through, uneven figure. Sold on the photographs, which means every mark has to be in them.
A piece with a check that runs through it, active insect damage, or rot is not grade B. It is firewood, and listing it is a breach of this agreement.
Answering enquiries
A buyer’s enquiry arrives by email with their address on it. Reply to it and you are talking to them directly — Kayu is not copied in and does not see what either of you says next.
Answer, even when the answer loses you the sale. “That set has gone” costs you nothing and buys you the next enquiry.
Answer quickly. Someone building an instrument is usually asking three sellers at once.
Their address was given to you to answer one question about one piece. Do not add it to a mailing list, sell it, or use it for anything else.
Questions asked on a listing page are public and stay on the listing for other buyers to read. Answer those the same way, and keep contact details out of them — an enquiry is where those belong.
Agreeing the sale
The price on your listing is what a buyer arrives expecting to pay. Postage, packing, insurance and any duties are for the two of you to settle, and Kayu adds nothing to either figure.
Take payment by a method that protects the buyer — a PayPal invoice or a card payment through your own account. It is in your interest as much as theirs: a buyer sending money abroad to someone they have never met is doing something uncomfortable, and a traceable, protected payment is what makes it possible at all.
Never pressure a buyer into a bank transfer, a “friends and family” payment or anything else that strips their protection. It is the clearest signal of a seller worth removing, and we will treat it that way.
The invoice, the receipt, the VAT and the tax are yours. Kayu has no record of what you agreed and cannot produce one for you.
Sending the parcel
Agree a dispatch time with the buyer before they pay, and keep to it. It is the single most common reason a sale sours, and the one entirely within your control.
Pack for the journey the wood is actually making, and send it tracked. Damage in transit is your parcel, your packing and your choice of carrier — the buyer had no say in any of it, and their payment provider will see it the same way.
Export documents, customs declarations and phytosanitary paperwork for the consignment are yours to complete. Import duties at the destination are the buyer’s, and they are told so before they contact you.
When a sale goes wrong
It is between you and the buyer. Kayu will not refund them on your behalf, because it never held the money, and it will not decide who is right about a piece of wood it has never seen.
If you sold as a business to a consumer in the EU, they have a right to change their mind within fourteen days of receiving the goods, and a further right against faults for two years. Those are the law and this agreement does not shorten them. If you sold privately, they largely do not apply — which is exactly why buyers are told which you are.
Buyers can and do report sellers to us. We cannot settle your sale, but we can read the listing against what arrived, and a pattern of upheld complaints — wood that is not as described, parcels that never went, buyers pushed off a protected payment — leads to listings coming down and the account being suspended. There is no threshold; a pattern is recognisable without arithmetic, and at this size a percentage would be noise.
Liability
Kayu provides a listing service, as it is, and does not promise the site will be uninterrupted or that listing here will produce sales. It is not liable for anything arising out of a sale it was not party to.
Where Kayu is liable to you at all, that liability is limited to the fees you have paid it in the previous twelve months — which is currently nothing — and does not extend to lost profits or indirect loss. Nothing in this section removes a right you have under the law of the country you live in, and nothing in it limits liability for death, personal injury or fraud.
You are responsible for what you list. If a claim reaches Kayu because of your wood, your description, your paperwork or your photographs — including a claim that timber was illegally harvested or unlawfully exported, or that an image you uploaded was not yours to use — you will cover the cost of it.
If your listing is reported
Anyone can report a listing — a buyer, another seller, or a stranger who knows more about a species than either of us. Most reports come to nothing. Being reported is not an accusation that has been believed.
A person reads it and decides. If anything happens to your listing you are told by email, in writing, with the reason — not a code, and not silence. Your other listings and your shop are unaffected.
If we get it wrong, reply to that email and say why. A person reads the reply and the listing goes back up if we were mistaken. You are never left with a listing that vanished and no way to argue about it.
We do not tell you who reported you. That is deliberate: people who spot protected timber are often trading in the same market as you, and they would stop reporting if it were not confidential.
Ending it
You can stop listing whenever you want: take your listings down and tell us. We can end it too, with notice, or immediately where there is fraud, illegal material, or a risk to buyers.
Sales you have already agreed are still yours to complete. Ending your account here does not end them.
Changing this agreement
Each version has a date, and what you accepted is recorded against it. When we change something that matters we publish a new version and ask you to accept it; you will see the request on your compliance page.
Kayu charges no fee today. If that changes — and it will, if the platform is to pay for itself — it will be a new version with the amount in it, published before it applies and shown to you to accept. It will never appear quietly on a sale you have already agreed.
Law and contact
This agreement is governed by Bulgarian law, and the courts of Bulgaria have jurisdiction, without taking away any protection you have under the law of the country you live in.
Operator details to be published here before launch — company name, registration number, registered address and a contact telephone number.
Anything at all: orders@kayushop.eu. A person reads it.
