SHIPPING POLICY.

Shipping from RioVex.

This policy applies to orders placed with RioVex Research LLC and should be read with the Terms & Conditions, Research Use Only Policy, and Refunds & Returns Policy.

RioVex ships eligible research-designated materials to supported United States destinations using the shipping methods made available during checkout. Submission of an order does not guarantee acceptance, same-day shipment, or delivery on a particular date. Orders remain subject to payment confirmation, inventory availability, address review, fraud screening, research-use review, compliance review, and other reasonable fulfillment requirements.

Before an order ships.

Orders placed before 4:30 PM Central Time on a business day are generally prepared and shipped the same business day. Orders placed after 4:30 PM Central Time, or on weekends or holidays, generally ship the next business day.

Business days are Monday through Friday, excluding federal holidays and carrier-observed holidays. Processing time is separate from carrier transit time. High order volume, inventory confirmation, payment or compliance review, address questions, weather, carrier conditions, or other operational circumstances may extend processing.

Creation of a shipping label does not necessarily mean that the carrier has received or scanned the package.

Options are displayed at checkout.

Available shipping methods, delivery speeds, rates, service levels, and destination eligibility are displayed during checkout and may vary or change. The method selected at checkout governs the order unless RioVex and the customer agree otherwise.

Free shipping is available for qualifying orders over $150. Eligibility and the applicable free-shipping method are shown during checkout.

RioVex does not currently offer shipping insurance or signature-required delivery service.

Carrier transit estimates begin after carrier acceptance and are estimates rather than guaranteed delivery commitments unless RioVex expressly states otherwise in writing. RioVex does not guarantee carrier performance, routing, scanning frequency, or delivery timing after transfer to the carrier.

Follow the shipment.

After an order ships, RioVex generally sends a shipment notification with available tracking information to the contact information provided at checkout. Tracking may take time to update after a label is created, after carrier pickup, or between carrier scans.

Customers should monitor tracking and contact RioVex with the order number if tracking shows an unusual delay, conflicting status, or other apparent issue. Transactional communications may be sent regarding verification, fulfillment, tracking, carrier issues, delivery, and claim review.

Standard shipping without cold packs.

Unless a product page or order confirmation clearly states otherwise, RioVex products are generally provided in lyophilized, freeze-dried form and ship without cold packs or cold-chain carrier service.

Short-term exposure to normal transit conditions, including temporary warmth during delivery, is generally expected during standard shipping. Cold-chain or special-handling service applies only when expressly offered and selected or confirmed for the applicable order.

A concern involving visible shipping damage, compromised packaging, or apparent product-integrity issues must be reported through the claim process in this policy. This section does not replace product-specific storage information provided by RioVex.

Accurate information and a secure destination matter.

Customers are responsible for providing a complete, accurate, and deliverable shipping address and for reviewing order information before checkout. RioVex cannot guarantee address changes after processing begins.

The customer is responsible for delays, returns, additional charges, or delivery problems caused by incorrect or incomplete information, an undeliverable address, missed delivery attempts, refused delivery, failure to retrieve a shipment, or an unsafe delivery location, except where applicable law requires otherwise.

Customers should monitor tracking and promptly retrieve delivered packages. If theft or delivery security is a concern, the customer should use an appropriate secure address or any carrier delivery-management option independently available to the customer. Additional shipping fees may apply to an approved correction or reshipment.

Delivery records guide review.

Carrier tracking is generally the primary source for shipment and delivery status after RioVex transfers a package to the carrier. A carrier delivery scan may be considered evidence of delivery, subject to applicable law, available carrier records, and any carrier investigation.

RioVex is not responsible for a package lost or stolen after confirmed delivery when the order was shipped to the address provided by the customer, except where responsibility cannot lawfully be excluded or RioVex expressly approves a resolution.

For a suspected package lost in transit, the customer should promptly contact RioVex and cooperate with any carrier trace, missing-mail search, recovery request, affidavit, or other investigation reasonably required before claim eligibility is determined.

Transit times are estimates.

Shipping and delivery may be delayed by carrier disruptions, weather, natural disasters, holidays, high-volume periods, transportation interruptions, supply-chain issues, incorrect routing, scanning delays, security reviews, governmental action, force-majeure events, or other circumstances outside RioVex's reasonable control.

RioVex may provide available information and reasonable support but does not guarantee a carrier's performance or delivery timing. A processing or transit delay alone does not automatically create eligibility for a refund, credit, replacement, or reshipment.

Report an issue within seven days.

A request for review must be submitted within seven (7) calendar days after delivery for a damaged, missing, incorrect, or other fulfillment issue. A suspected in-transit loss should be reported promptly after tracking shows an unusual delay so a carrier investigation may begin.

The request must include the order number, the customer name and contact information used at checkout, a written description, and clear photographs of the outer packaging, shipping label, packing materials, contents, and affected item when applicable. RioVex may request additional information or carrier documentation reasonably needed to investigate.

Customers must retain the affected item, packaging, label, and packing materials until RioVex completes review or authorizes disposal. Do not send any product back without written return authorization. Incomplete, late, inconsistent, duplicate, excessive, or suspicious claims may be denied or subjected to additional review to the extent permitted by law.

Each claim is reviewed on its record.

RioVex generally reviews a complete claim and responds as soon as reasonably possible, typically within two to three business days. Review may include fulfillment records, photographs, customer communications, tracking, delivery confirmation, carrier records, order history, and other relevant information.

Eligible situations may include an incorrect item shipped by RioVex, a verified fulfillment error, visible transit damage supported by documentation, or a package confirmed lost in transit after carrier investigation.

If RioVex approves a claim, RioVex may select an appropriate replacement, reshipment, store credit, or refund, subject to applicable law and the Refunds & Returns Policy. Approval of one claim does not guarantee approval of another. Shipping and handling charges are generally nonrefundable unless RioVex approves otherwise or law requires otherwise.

Research-material integrity controls apply.

Orders begin processing quickly. A request to change or cancel an order is not guaranteed and may be unavailable after processing or fulfillment begins.

All sales are final except where RioVex approves a resolution or applicable law requires otherwise. RioVex does not accept returns or provide refunds for change of mind, customer ordering error, refused delivery, address error, failure to retrieve a package, ordinary transit delay, improper storage after delivery, or a research result that does not meet expectations.

Opened, used, handled, reconstituted, improperly stored, temperature-exposed, or otherwise compromised products are not eligible for return. If RioVex approves a refund, it will generally be issued to the original payment method when possible. Financial-institution processing may take approximately five to ten business days after RioVex processes the refund.
