Terms of Sale

Article 1Who we are

XV Molecular is the trading name under which [LEGAL ENTITY NAME] operates the website xvmolecular.com and sells the products described on it. In these terms, "we", "us" and "our" refer to that seller, and "you" refers to the person or organisation placing an order.

We are a sole trader registered in the Croatian Crafts Register (Obrtni registar). A sole trader is not a company: the business is carried on by a natural person who is personally responsible for its obligations. For that reason you will not find a company number or share capital for us anywhere, and any document that describes us as a limited company is incorrect.

Article 2Scope of these terms

These Terms of Sale apply to every order placed through xvmolecular.com and to the contract that results from it. By placing an order you confirm that you have read these terms, that you accept them, and that you are able to enter into a binding agreement. If you do not accept them, please do not place an order.

The agreement between us consists of these Terms of Sale, the shipping information published at shipping.html, the Privacy Policy, and the order confirmation we send you. Where those documents differ, the order confirmation prevails for the details of your specific order, and these terms prevail for everything else. Product pages, certificates of analysis and safety data sheets describe the goods; they do not create obligations beyond those set out here.

The version of these terms that applies to your order is the version published on the website at the moment you place it. We keep the last updated date at the top of this page current so that the applicable version can be identified. These terms are written and published in English, which is the language of the contract; documents required by Croatian tax legislation may additionally be issued in Croatian.

Nothing in these terms limits or removes any right you have under mandatory law that cannot be varied by agreement. Where a provision of these terms conflicts with such a right, the mandatory rule applies and the rest of the document remains in force.

Article 3Research use only

The products are not sterile and are not pyrogen-free. They are shipped as research reagents to be handled in a laboratory environment by people trained to handle laboratory chemicals, using the precautions described in the applicable safety data sheet.

We make no claim, express or implied, about any physiological, therapeutic, clinical or performance effect of any product we sell. Nothing on our website, in our documents, in our correspondence or in any material we publish is a representation that a product treats, prevents, diagnoses, improves or influences any condition in a human being or an animal. Published scientific literature that may be referenced on the site is the work of its authors, describes their experiments and not our products, and is provided for scientific context only. Any dosing, protocol, reconstitution or administration information that you may encounter elsewhere on the internet does not originate from us and is not endorsed by us.

By placing an order you represent and warrant that:

• you are a qualified researcher, or you are ordering on behalf of a laboratory, institution or organisation engaged in scientific research;
• you have the training, facilities and equipment needed to handle laboratory chemicals safely;
• you will use the product solely for in vitro or laboratory research and for no other purpose;
• you will not administer the product to yourself, to another person, or to any animal, and will not resupply it to anyone who intends to do so;
• you will comply with every law, regulation, licence and institutional rule that applies to you where you receive and use the product, including rules on import, possession, handling, record-keeping and disposal; and
• you will not resell, relabel or repackage the product for human or veterinary use, or in any way that suggests such a use.

These representations are a condition of sale and not a formality. If we have reason to believe that a product is intended for consumption or for onward supply for consumption, we may refuse or cancel the order under Article 5. Where you breach this article, we accept no responsibility for the consequences, to the extent that liability may lawfully be excluded — see Article 11, which does not exclude liability that Croatian law does not allow us to exclude.

Article 4Eligibility to buy

You must have reached the age of majority in your jurisdiction and be at least 21 years old. This is the confirmation shown when you enter the website, and placing an order repeats it.

We do not sell to residents of the United States. Products are not available to U.S. residents and we do not ship to addresses in the United States or its territories. If an order is placed with a United States delivery address, or we otherwise establish that the buyer is a U.S. resident, we will not accept it; where payment has already been received we will return it in accordance with Article 7, less unavoidable network transaction fees. The same applies to any destination we are prohibited from supplying under applicable sanctions or export rules.

Import rules for research chemicals and peptides differ from country to country, and in some places these goods may be restricted or prohibited, require a licence, or attract inspection. Checking the position in your own country before you order is your responsibility, not ours. We cannot advise on the law of your jurisdiction and we do not warrant that any product may lawfully be imported into or possessed in a particular country. If a shipment is detained, seized, returned or destroyed by customs or another authority in the destination country because the goods may not lawfully be imported there, that is a consequence of the buyer's own legal position and Article 8 applies.

Where you order on behalf of an institution or organisation, you confirm that you are authorised to do so and that the organisation accepts these terms.

Article 5Orders and acceptance

The presentation of products on the website is an invitation to place an order. It is not a binding offer and it is not a guarantee that an item is in stock.

When you complete checkout, you make an offer to buy the items in your basket on these terms. We may acknowledge the order automatically and issue payment instructions; that acknowledgement is a confirmation that we have received your order, not acceptance of it. The contract is concluded at the moment we confirm that payment has been received in full and confirm acceptance of the order, ordinarily by email. Until that moment there is no contract between us.

We may refuse an order, in whole or in part, and we may cancel an order before dispatch. Reasons include, but are not limited to: the item is not available; the price or product information was affected by an obvious error; the delivery address is in a country we do not supply, or in the United States; the eligibility conditions in Articles 3 and 4 are not met, or we have reason to doubt that they are; the order appears to be for resale for human or veterinary use; applicable sanctions or export controls prevent supply; the payment could not be reconciled with the order; or we are required to refuse by law. We are not obliged to state a reason, and refusing an order does not make us liable for any resulting loss. Where payment has already been received for an order we do not accept, we return it in accordance with Article 7.

Please check the confirmation we send you as soon as you receive it. If the products, quantity or delivery address are wrong, tell us at [CONTACT EMAIL] immediately. Changes to an order can only be made before dispatch, and only if we are able to make them.

Where a price, quantity or specification on the website is obviously incorrect — for example an evident typographical error in a price — we are not obliged to supply at that figure. We will tell you before dispatch and you may confirm the corrected order or cancel it and have your payment returned.

Article 6Prices, VAT and shipping charges

Prices on the website are stated in euro (EUR), which is the currency of the contract even where payment is made in cryptocurrency. The price applicable to your order is the price displayed at the moment you place it.

Whether value added tax is charged on your order, and at what rate, follows Croatian tax legislation and the place of supply rules that apply to it. The treatment applied to your order is shown on the invoice issued with it. If you are ordering as a business inside the European Union and believe a different treatment applies to you, tell us before you pay, because an invoice already issued cannot always be changed afterwards.

Shipping is charged separately. The shipping cost applicable to your destination is added at checkout and shown to you, together with the total, before you are asked to pay. Nothing is added after that point: the total you see is the total you pay to us.

Import duties, import VAT, customs clearance charges, brokerage fees and any similar charge raised in the destination country are not included in our prices and are not paid by us. They are payable by the recipient. See Article 8.

An invoice is issued for every order in accordance with Croatian law and is sent to the email address you give us.

Article 7Payment in cryptocurrency

Payment for orders is currently accepted in cryptocurrency only. We accept Ether (ETH), Tether (USDT) and Solana (SOL). Bitcoin (BTC) is announced as coming and is not yet available; it becomes available only when the checkout offers it, not before. We do not accept card payments, bank transfers, cash on delivery or any other method, and you should treat any message that asks you to pay us by another route as fraudulent.

7.1 A unique address for each order

Every order is assigned its own deposit address. The address shown to you belongs to that order alone. Do not reuse an address from an earlier order, do not pay for two orders to the same address, and do not send funds to an address given to you by anyone outside the checkout page or our own confirmation email. Funds sent to an address that is not the one issued for your order cannot be matched to it and, in most cases, cannot be recovered.

7.2 The amount and the quote window

Prices are set in euro. The amount of cryptocurrency to be sent is calculated from the euro total using the exchange rate at the time the order is placed, and is valid for the limited quote window shown on the payment page. Cryptocurrency prices move, which is the only reason the window is short. If you pay within the window, the quoted amount settles the order in full whatever happens to the rate afterwards. If the window expires before your transaction is broadcast, the quote lapses and the order is not confirmed; you may request a fresh quote, and funds that arrive after expiry are handled as set out in 7.4.

7.3 Networks, and the irreversibility of what you send

Send the exact asset shown, on the exact network shown. This matters in particular for USDT, which exists on several networks under the same name: a transfer made on a network we do not list will not reach us in a usable form. Sending a different asset to the address, or the right asset on the wrong network, will in most cases result in permanent loss.

If a mistaken transfer is technically recoverable — for example, funds that did reach an address under our control — we will make reasonable efforts to return them to an address you confirm in writing, less the network fees involved. We cannot promise recovery and we do not accept responsibility for funds that are not recoverable.

We recommend sending from a wallet you control. Payments sent from an exchange or another custodial account may be delayed, may arrive net of the platform's own fee, and cannot always receive a return transfer, which complicates withdrawal and refunds.

7.4 Underpayment, overpayment and late payment

Cryptocurrency transfers sometimes arrive for a different amount than intended, usually because a fee was deducted at the sending end.

• If less than the quoted amount arrives, the order is not paid and is not released for dispatch. We will contact you and you may either send the difference to the same address, or ask us to return what was received. A return is made to an address you confirm in writing, less the network fee required to make the transfer.
• If more than the quoted amount arrives, we will contact you and return the surplus to an address you confirm in writing, less the network fee, unless you ask us instead to apply it to the same order or to a further order. Where the surplus is smaller than the network fee needed to return it, a transfer is not economically possible; we will tell you and agree what to do.
• If payment arrives after the quote window has expired, we will contact you. If the euro value of what arrived still covers the order at the rate then applying, we may accept it and confirm the order. If it does not, you may top up the difference or ask for a return on the same basis as an underpayment.

7.5 Confirmation on the network

Payment counts as received when the transaction has reached the number of network confirmations stated on the payment page for the asset you used. Until then the transaction is pending, whatever your wallet displays. Confirmation times depend on the network and on congestion, not on us. Dispatch and the contract itself both follow confirmation, as set out in Article 5.

7.6 What we are, and what we are not

We accept cryptocurrency solely as payment for the goods we sell. We do not hold, custody, manage or invest assets for you, we do not operate an exchange or a payment service for third parties, and we do not provide investment advice of any kind. Nothing on the checkout page is a recommendation to buy or hold any digital asset. We may refuse funds where we are required to do so by law or by applicable sanctions rules, or where the sending address is subject to a credible public report of theft or sanctions listing; in that case the order is not accepted and we will follow the applicable legal procedure.

Where a refund or return is due to you under any part of these terms, it is calculated in euro — the currency of the contract — and paid in the cryptocurrency used for the original payment, converted at the rate applying at the time the refund is made, unless we agree something else with you in writing. Network fees for the transfer are deducted from the amount sent. Because rates move, the quantity of cryptocurrency you receive back will usually differ from the quantity you sent, in either direction; the euro value is what we make good.

Article 8Delivery, risk and customs

Shipping destinations, carriers, packaging and indicative transit times are described at shipping.html, which forms part of these terms. We ship worldwide with the exception of the United States and any destination we are prohibited from supplying.

Dispatch follows confirmation of payment under Article 7. Any delivery time we state is an estimate based on ordinary carrier performance; it is not a guaranteed date, and postal handling, customs inspection, weather, industrial action and public holidays are outside our control. If a shipment appears to have gone astray, contact us at [CONTACT EMAIL] with your order number and we will open an enquiry with the carrier.

You are responsible for the accuracy and completeness of the delivery address and the contact details you give us. Where a parcel cannot be delivered, is refused on delivery, or is returned to us because the address was wrong or incomplete, because nobody collected it within the carrier's holding period, or because charges due in the destination country were not paid, we will contact you; a further attempt at delivery is charged again at the applicable shipping rate.

Where you are a consumer, risk of loss or damage passes to you when you, or a third party you have designated other than the carrier, take physical possession of the goods. Where you are not a consumer, risk passes when the goods are handed to the carrier.

Shipments are declared in accordance with the law applicable to them. We do not mis-declare contents or value, and we cannot agree to do so on request. Import duties, taxes and clearance charges are the recipient's responsibility, as stated in Article 6. Where an authority in the destination country detains, seizes, returns or destroys a shipment because the goods may not lawfully be imported there, the loss falls on the buyer under Article 4; where the same happens for a reason attributable to us, Article 10 applies.

Article 9Right of withdrawal

If you are a consumer within the meaning of the Croatian Consumer Protection Act — a natural person buying outside their trade, business, craft or profession — you have the right to withdraw from a distance contract within 14 days, without giving any reason. The period runs from the day on which you, or a third party you designate other than the carrier, take physical possession of the goods. Where an order is delivered in several consignments, it runs from receipt of the last one.

The right of withdrawal is a consumer right. It does not apply where you buy as a business, a laboratory, an institution or another organisation; the position of such buyers is governed by Article 10 and by the general law of obligations.

9.1 How to withdraw

Send us an unambiguous statement that you are withdrawing from the contract, before the 14 days expire, to [CONTACT EMAIL]. You may use the model form in the Annex, but you are not required to. Please quote your order number so that we can identify the order. We will acknowledge receipt of your notice without delay. Sending the goods back without notice is not by itself a valid withdrawal.

Return the goods to [RETURN ADDRESS] without undue delay and in any event within 14 days of telling us. You bear the direct cost of returning the goods unless we have agreed otherwise in writing. Use a traceable service; the goods remain your responsibility until they reach us, and proof of dispatch protects you. The practical steps are also set out at returns.html.

9.2 Refund

We refund all payments received from you for the returned goods, including the standard delivery cost we charged, within 14 days of the day we are informed of your withdrawal. Where you chose a delivery method more expensive than the cheapest standard option we offer, we refund the standard cost, not the difference. We may withhold the refund until we have received the goods back, or until you supply evidence that you have sent them, whichever happens first. Refunds are made under the final paragraph of Article 7: in euro terms, paid in the cryptocurrency used, to an address you confirm in writing.

You are liable for any diminished value of the goods resulting from handling beyond what is necessary to establish their nature, characteristics and functioning.

9.3 Statutory exceptions that may apply

Consumer law itself sets out contracts to which the right of withdrawal does not apply. We would rather state plainly which one may be relevant here than let you discover it at the point of return.

We do not treat that exception as a general answer to every withdrawal. Vials that are unopened, intact, with the seal undamaged, and in the condition in which they were delivered may be returned within the 14 days on the terms above. Whether the exception applies to a particular item depends on the facts, and if we rely on it we will tell you why.

Other statutory exceptions may apply where they fit the circumstances of an order, for example goods made to a consumer's specification or clearly personalised. We will not invoke an exception that does not genuinely apply.

Article 10Conformity and complaints

We are liable for material defects in the goods we sell in accordance with the Croatian Civil Obligations Act (Zakon o obveznim odnosima) and, for consumers, the Consumer Protection Act. In short: the goods must correspond to the description and documentation supplied with them, including the batch certificate of analysis, and must be free from defects that existed at the time risk passed to you. The statutory liability period for material defects in a consumer sale is two years from delivery.

Notice of a defect should reach us as soon as you can reasonably give it. Consumers are not required to give notice within any shorter period than the law provides. Buyers who are not consumers must give notice of apparent defects without delay after inspection, and of hidden defects within the periods the Civil Obligations Act sets for them; late notice may cost a commercial buyer the right to rely on the defect.

Send complaints to [CONTACT EMAIL], or in writing to [REGISTERED ADDRESS]. Please include the order number, the batch number printed on the vial, a description of the problem and, where the issue is visible, photographs of the vial, the label, the seal and the outer packaging as received. Where a parcel arrives visibly damaged, photograph it before opening it if you can, and keep the packaging until the complaint is resolved — carriers require it.

Where a written complaint is made by a consumer, we will reply in writing within 15 days of receiving it, as Croatian consumer legislation requires, and we keep a record of complaints received and answers given. If a defect is established, the remedies available to you are those the law provides, which for goods of this kind will ordinarily mean replacement, a proportionate price reduction, or termination of the contract with a refund. We may ask you to return the item, at our cost, so that the defect can be examined; where the goods are a laboratory chemical, we may ask you to keep and return the vial rather than dispose of it.

This article concerns defects in the goods. It does not make us responsible for results obtained in your own experiments, for storage or handling after delivery that departs from the conditions stated on the certificate of analysis and the safety data sheet, or for use of a product after the expiry date printed on it.

Article 11Limitation of liability

Subject to the paragraph above, and to the fullest extent permitted by law, we are not liable for indirect or consequential loss, loss of profit, loss of revenue, loss of business or opportunity, loss of data, wasted expenditure, or the cost of repeating work — including experimental work — however arising.

Again subject to the paragraph above, we are not liable for loss arising from: use of a product otherwise than for laboratory research, and in particular any administration to a person or an animal, contrary to Article 3; the buyer's failure to comply with the law of the jurisdiction in which the goods are received or used, or with import restrictions, contrary to Article 4; storage or handling after delivery that departs from the stated conditions; the design, conduct or interpretation of the buyer's own research; delay, detention, seizure or destruction of a shipment by a carrier, customs or another authority; failure, congestion, fork or malfunction of a blockchain network or a wallet or exchange used by the buyer; or a payment sent to the wrong address, network or asset, as described in Article 7.

Where liability may lawfully be limited, our total liability arising out of or in connection with an order is limited to the amount you paid us for that order.

If you are not a consumer, you agree to indemnify us against claims brought by third parties arising from your breach of Article 3 or Article 4 — again, save in respect of the liabilities set out in the box above.

Article 12Intellectual property

The website, its design, text, photographs, illustrations, data presentations and document layouts — including the presentation of certificates of analysis and safety data sheets published on it — together with the XV Molecular name and logo, are owned by us or used by us under licence, and are protected by copyright and trademark law.

You may view, download and print these materials for your own internal or research purposes, and you may keep and pass on the documents that accompany the goods you bought where you need to do so for regulatory, institutional or record-keeping reasons. You may not otherwise copy, republish, systematically extract, scrape, resell, or use our materials to promote another business, and you may not present our documents as relating to goods other than the batch they were issued for.

Analytical reports issued by an independent laboratory remain the work of that laboratory and are published here in the form in which they were issued, with the identifiers needed to verify them at source. Third-party names and marks referred to on the site belong to their respective owners and are used to identify those parties, not to suggest any endorsement of us by them.

Buying a product does not transfer any intellectual property right to you.

Article 13Force majeure

Neither party is in breach of the contract, or liable for delay or failure in performing it, where the cause is beyond that party's reasonable control. Events of that kind include natural disasters and severe weather, fire, flood, war, civil unrest, terrorism, epidemics and public health measures, strikes and industrial action, interruption of postal or carrier services, failure of utilities or telecommunications, sanctions, embargoes and other governmental or regulatory action, and failure or sustained disruption of a blockchain network on which a payment depends.

The affected party must tell the other as soon as it reasonably can. Performance is suspended for the duration of the event and the time for performance extends accordingly. Where the event continues for longer than is reasonable in the circumstances, either party may terminate the affected order by notice, in which case we return payment received for goods not delivered, in accordance with Article 7.

This article does not relieve either party of an obligation to pay a sum that had already fallen due before the event began, and it does not affect a consumer's statutory rights.

Article 14Governing law and disputes

These terms and any contract made under them are governed by the law of the Republic of Croatia, excluding its conflict of laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country in which you are habitually resident. Those provisions continue to apply to you in full, whatever this document says.

We would rather resolve a problem directly, and most are resolved that way: write to [CONTACT EMAIL] and we will engage with the substance of the complaint. Where a dispute cannot be settled between us, the courts of the Republic of Croatia having jurisdiction at our registered office have jurisdiction, subject to the following.

Where you are a consumer domiciled in the European Union, the jurisdiction rules of Regulation (EU) No 1215/2012 apply: you may bring proceedings against us either in the Croatian courts or in the courts for the place where you are domiciled, and we may bring proceedings against you only in the courts of your domicile.

Consumers may also use out-of-court dispute resolution. A dispute may be referred to an alternative dispute resolution body notified to the European Commission that is competent for the trader, and consumers resident in another EU or EEA state can obtain assistance from the European Consumer Centre in their own country. Note that the European Commission's online dispute resolution (ODR) platform, to which traders were formerly required to link, ceased operation in July 2025 and is no longer available; we point to it here only to explain its absence. Using an out-of-court procedure is voluntary and does not affect your right to go to court.

If any provision of these terms is held to be invalid or unenforceable, the remaining provisions continue in force, and the invalid provision is replaced by the rule that comes closest to its lawful purpose.

Article 15Changes to these terms

We may amend these terms — to reflect a change in what we sell or how we sell it, a change in the payment methods we accept, or a change in the law. Amendments apply to orders placed after the amended version is published. They do not change the terms of a contract already concluded with you, which continues to be governed by the version in force when you placed your order.

The current version is always the one published on this page, dated at the top. We suggest saving or printing a copy of the terms when you order, so that you have the version that applies to your contract; you may also ask us for it at any time and we will send it to you.
