By using this website or purchasing from Xtenvia, you confirm that you have read, understood, and agreed to these Terms and all policies incorporated by reference.
Acceptance of these Terms
These Terms and Conditions (“Terms”) govern your access to and use of the Xtenvia website, its content, accounts, services, communications, and purchasing features (collectively, the “Services”). “Xtenvia,” “we,” “us,” and “our” refer to the operator of this website. “You” and “your” refer to each visitor, account holder, purchaser, or organization using the Services.
By accessing the Services, creating an account, submitting an order, or otherwise indicating acceptance, you enter into a binding agreement with Xtenvia. If you do not agree, do not use the Services. Our Privacy Policy, Shipping Policy, Return and Refund Policy, and RUO Disclaimer are incorporated into these Terms.
Eligibility and account responsibility
You must be at least 21 years old, have legal capacity to enter into a contract, and be legally permitted to access and purchase the products offered in your jurisdiction. By placing an order on behalf of a business, institution, laboratory, or other organization, you represent that you have authority to bind that organization to these Terms.
You must provide accurate, current, and complete information. You are responsible for safeguarding your login credentials and for activity conducted through your account. Notify us promptly if you suspect unauthorized access. We may request additional information to verify identity, age, billing details, intended research status, or authority to purchase.
Research Use Only
All products offered by Xtenvia are intended strictly for laboratory research use only. They are not intended for human or veterinary consumption, diagnostic use, therapeutic use, clinical use, compounding, administration, or use in food, drugs, cosmetics, or household products.
By purchasing, you represent and warrant that you are a qualified researcher or authorized purchaser acquiring products solely for lawful laboratory research. You accept responsibility for evaluating suitability, complying with applicable laws and institutional requirements, maintaining appropriate facilities and safeguards, and ensuring proper handling, storage, use, recordkeeping, and disposal.
Information on the website is provided for general research reference and product identification. It is not medical advice, prescribing information, treatment guidance, or a substitute for professional judgment. No statement on the website should be interpreted as encouraging an unapproved or unlawful use.
Product information and availability
We work to present product descriptions, images, specifications, availability, and documentation accurately. Minor differences in packaging, labels, color, dimensions, or presentation may occur. Website content may contain errors or omissions and may be corrected without prior notice.
Availability is not guaranteed. We may modify the catalog, restrict quantities, limit sales by customer or jurisdiction, substitute updated packaging, or discontinue products. Certificates, reports, or other batch documentation apply only to the specific lot identified in that document and should not be attributed to another lot.
Orders, pricing, and payment
An order submission is an offer to purchase and does not constitute acceptance. We may accept, decline, limit, place on hold, or cancel an order for reasons including product availability, suspected error, payment failure, fraud risk, compliance concerns, shipping restrictions, or inability to verify purchaser information. An automated confirmation only acknowledges receipt.
Prices are displayed in the currency indicated at checkout and may change without notice. Applicable shipping charges, taxes, processing charges, or other disclosed fees will be shown before order submission when practicable. You authorize us and our payment providers to charge the selected payment method for the final order total.
You represent that you are authorized to use the submitted payment method. Orders may be delayed until payment clears. If a price, discount, product, or calculation is materially incorrect, we may correct or cancel the affected transaction and issue any appropriate refund.
Promotions and coupon codes
Promotions are subject to their stated dates, eligibility rules, exclusions, purchase minimums, and usage limits. Unless expressly stated otherwise, coupon codes have no cash value, cannot be sold or transferred, cannot be applied retroactively, and cannot be combined. We may modify or discontinue a promotion where permitted by law, including in response to misuse, technical error, or suspected fraud.
Shipping, delivery, and risk
Shipping dates and delivery estimates are estimates, not guarantees. Carrier delays, weather, address errors, access restrictions, customs, force majeure events, and other circumstances outside our reasonable control may affect delivery. You are responsible for providing a complete and deliverable address and for reviewing tracking information.
Ownership and risk of loss transfer as provided by applicable law and the selected shipping arrangement. Report visible damage, missing items, or delivery discrepancies promptly in accordance with our Shipping Policy. We may require photographs, packaging, tracking details, identification, or other reasonable documentation before resolving a claim.
You are responsible for determining whether a product may lawfully be purchased, possessed, imported, shipped, or used in your location. We may restrict or cancel shipments to certain destinations.
Returns, refunds, and cancellations
Returns, replacements, refunds, and order cancellations are governed by our Return and Refund Policy. Because research products may be sensitive to storage conditions, chain of custody, contamination, or tampering, opened, used, altered, improperly stored, or unverified products may be ineligible for return.
Contact support before sending any item back. Unauthorized returns may be refused. Refunds approved by Xtenvia are normally issued to the original payment method, subject to payment-network processing times and applicable law.
Fraud prevention and chargebacks
We may use fraud-prevention tools, transaction monitoring, address verification, device data, order history, and manual review to protect customers and the Services. We may request verification, delay fulfillment, or cancel transactions presenting elevated risk.
If you believe a charge or order is incorrect, contact us first so we can investigate. Nothing in these Terms limits rights you may have under applicable payment-network rules or law. Knowingly submitting false information, using an unauthorized payment method, or initiating a fraudulent claim may result in account restriction and referral to relevant service providers or authorities.
Acceptable website use
You may not misuse the Services, attempt unauthorized access, introduce malicious code, scrape or harvest information without permission, interfere with website operation, evade purchasing restrictions, impersonate another person, use automated systems to abuse checkout or promotions, or use the Services for unlawful activity. We may suspend or terminate access where we reasonably believe these Terms, another policy, or applicable law has been violated.
Intellectual property
The Xtenvia name, branding, website design, graphics, text, product presentation, software, and other original content are owned by or licensed to Xtenvia and are protected by applicable intellectual-property laws. Except for limited personal or internal business use of the website, no license is granted to copy, reproduce, modify, distribute, sell, frame, reverse engineer, or create derivative works without prior written permission.
Third-party services and links
The Services may rely on or link to third-party providers, including payment processors, carriers, analytics services, and external websites. Their services and terms are controlled by those third parties. Xtenvia is not responsible for third-party content, availability, privacy practices, or acts beyond our reasonable control. A link does not necessarily imply endorsement.
Disclaimers
To the fullest extent permitted by law, the Services and website content are provided on an “as is” and “as available” basis. Except for warranties that cannot lawfully be excluded and any express written product commitment provided by Xtenvia, we disclaim implied warranties including merchantability, fitness for a particular purpose, title, and non-infringement.
We do not warrant that the website will be uninterrupted, error-free, or free from harmful components, or that content will meet every research objective. You are responsible for applying appropriate independent judgment, controls, qualifications, and validation to your research activity.
Limitation of liability
To the fullest extent permitted by applicable law, Xtenvia and its owners, officers, employees, contractors, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, loss of data, loss of revenue, loss of opportunity, or business interruption arising from or related to the Services, products, or these Terms.
Where liability cannot be excluded, our aggregate liability for a claim will not exceed the amount you paid to Xtenvia for the specific product or transaction giving rise to that claim during the twelve months preceding the event. Some jurisdictions do not allow certain exclusions or limitations, so parts of this section may not apply to you.
Indemnification
To the extent permitted by law, you agree to defend, indemnify, and hold harmless Xtenvia and its owners, officers, employees, contractors, and service providers from claims, losses, liabilities, and reasonable expenses arising from your unlawful use of the Services or products, your breach of these Terms, your violation of another party’s rights, or your handling or use of products outside their stated research purpose.
Changes, suspension, and termination
We may update these Terms by posting a revised version and changing the “Last Updated” date. Changes apply prospectively unless applicable law requires otherwise. Continued use after an update constitutes acceptance of the revised Terms. We may modify, suspend, or discontinue any portion of the Services and may restrict access for violation, security, compliance, or operational reasons.
Applicable law and disputes
These Terms and any dispute involving the Services will be governed by applicable United States federal law and the applicable law of the jurisdiction in which the Xtenvia website operator is legally established, without regard to conflict-of-law principles. The venue and forum for a dispute will be determined under applicable law unless the parties agree otherwise in writing.
Before filing a formal claim, you agree to contact us with a reasonable description of the issue and allow at least 30 days for a good-faith resolution attempt. This informal process does not prevent either party from seeking urgent injunctive relief or exercising rights that cannot lawfully be waived.
General provisions
If any provision is found unenforceable, it will be limited or removed to the minimum extent necessary and the remaining provisions will continue in effect. Our failure to enforce a provision is not a waiver. You may not assign your rights or obligations under these Terms without our consent; we may assign them in connection with a merger, reorganization, asset transfer, or change in control. These Terms and incorporated policies constitute the entire agreement regarding the Services.
