Shipping policy


Last Updated: August 31, 2026

This Shipping Policy describes the shipping and delivery practices for orders placed through BAC Science at bacscience.com.

By placing an order with BAC Science, you agree to this Shipping Policy as well as our Terms of Service and Return & Refund Policy.

Order Processing

Orders are processed as quickly as possible after payment has been successfully received and the order has been accepted.

Processing times are separate from carrier transit times.

Orders placed on weekends, holidays, or after applicable fulfillment cutoff times may begin processing on the next business day.

During periods of unusually high order volume, holidays, severe weather, carrier disruptions, or other circumstances outside our reasonable control, processing may take longer than usual.

Shipping Methods

Available shipping methods, estimated delivery times, and applicable shipping charges are displayed at checkout based on the destination and available carrier services.

Shipping options may vary depending on:

  • Delivery location;

  • Product ordered;

  • Package size and weight;

  • Carrier availability; and

  • Applicable shipping restrictions.

BAC Science reserves the right to select or substitute a comparable shipping carrier or service when reasonably necessary to complete delivery.

Shipping Rates

Shipping charges are calculated and displayed at checkout unless BAC Science expressly offers free or promotional shipping.

Any applicable shipping charge will be shown before you complete your purchase.

Delivery Estimates

Delivery dates and transit times displayed at checkout or provided in an order confirmation are estimates only unless expressly identified as guaranteed.

Once a package has been transferred to the shipping carrier, transit and final delivery are substantially controlled by the carrier.

BAC Science cannot guarantee carrier delivery times and is not responsible for delays caused by circumstances outside our reasonable control, including:

  • Weather;

  • Natural disasters;

  • Carrier delays or service interruptions;

  • Transportation disruptions;

  • High seasonal shipping volume;

  • Governmental actions;

  • Incorrect or incomplete delivery information;

  • Failed delivery attempts; or

  • Other events outside BAC Science's reasonable control.

A carrier delay does not automatically qualify an order for a refund, credit, or replacement.

Shipping Address

Customers are responsible for providing a complete and accurate shipping address when placing an order.

Please carefully verify your:

  • Recipient name;

  • Street address;

  • Apartment, suite, or unit number;

  • City;

  • State;

  • ZIP or postal code; and

  • Other applicable delivery information.

BAC Science is not responsible for packages that are delayed, misdelivered, returned, or lost because a customer provided an incorrect or incomplete shipping address.

If you notice an address error after submitting your order, contact us immediately. We will attempt to correct the address if the order has not entered fulfillment, but we cannot guarantee that changes can be made once an order has been submitted.

Tracking Information

When tracking is available, customers will generally receive tracking information after their order has shipped.

Please allow time for the carrier's tracking system to update after a shipping label is created.

The creation of a shipping label does not necessarily mean the carrier has already received or scanned the package.

Delivered Packages

If carrier tracking shows your package as delivered, but you cannot locate it, please:

  • Check around the delivery location;

  • Check with household members;

  • Check with neighbors;

  • Check with building management, reception, or mailroom personnel where applicable; and

  • Contact the shipping carrier for additional delivery information.

Please contact BAC Science if the package still cannot be located.

A carrier's confirmation that a package was delivered to the address provided with the order may be considered evidence of successful delivery.

BAC Science will review reported delivery issues individually but does not guarantee refunds or replacements for packages confirmed as delivered by the carrier.

Lost Packages

If tracking indicates that a shipment has been lost in transit or has stopped progressing for an unusual period, please contact us.

We may work with the carrier to investigate the shipment.

Depending on the circumstances and results of the carrier investigation, BAC Science may determine an appropriate resolution.

Reporting a package as lost does not automatically entitle the purchaser to a refund or replacement.

Stolen Packages

BAC Science is not responsible for packages stolen or removed from the delivery location after the shipping carrier has confirmed delivery.

Customers are responsible for providing a secure delivery location.

If package theft is a concern in your area, we recommend monitoring tracking information closely and using an available secure delivery option.

Damaged Shipments

If your order arrives visibly damaged, please photograph the package and its contents before discarding any shipping materials.

Contact BAC Science promptly and provide:

  • Your order number;

  • Photographs of the shipping package;

  • Photographs of the damaged product;

  • The shipping label;

  • A description of the damage; and

  • Any additional information reasonably requested to investigate the claim.

Please retain the product and all original packaging until the claim has been reviewed.

BAC Science will review eligible damage claims and determine the appropriate resolution in accordance with our Return & Refund Policy.

Refused Shipments

Orders that are refused by the recipient are not automatically eligible for a refund.

Shipping charges and other costs associated with a refused shipment may be the responsibility of the customer.

Because BAC Science maintains an All Sales Final policy, refusing delivery does not create a right to a refund.

Undeliverable and Returned Packages

If a package is returned to BAC Science because it was:

  • Addressed incorrectly;

  • Missing required address information;

  • Unclaimed;

  • Refused;

  • Subject to unsuccessful delivery attempts; or

  • Otherwise undeliverable due to circumstances attributable to the customer,

the original purchase is generally not eligible for a refund.

If BAC Science agrees to reship the order, the customer may be responsible for additional shipping and handling charges.

Product Storage After Delivery

Customers are responsible for promptly retrieving delivered packages and following any storage instructions provided with the applicable product.

BAC Science is not responsible for product deterioration or damage resulting from:

  • Failure to retrieve a delivered package promptly;

  • Leaving a package exposed to environmental conditions after delivery;

  • Improper storage;

  • Improper handling; or

  • Failure to follow product-specific storage instructions.

Customers should review the applicable product label and documentation for storage requirements.

Research Use Only Products

Products designated For Research Use Only (RUO) must be shipped, received, stored, handled, and used in accordance with applicable laws, product documentation, and our Terms of Service.

Shipping an RUO product to a customer does not constitute authorization or approval for any use inconsistent with its labeling or intended research purpose.

Shipping Restrictions

BAC Science reserves the right to restrict or decline shipment of a product to any destination where we reasonably determine that shipment may:

  • Violate applicable law;

  • Violate carrier restrictions;

  • Require licenses or authorizations that have not been provided;

  • Present unreasonable transportation or compliance risks; or

  • Otherwise be inappropriate.

The availability of a product on bacscience.com does not guarantee that it can legally or practically be shipped to every location.

International Shipping

If international shipping is offered, customers are responsible for determining whether the products ordered may legally be imported into the destination country.

International customers may be responsible for customs duties, import taxes, brokerage fees, VAT, clearance charges, or other governmental fees.

Unless expressly stated otherwise, these charges are not included in the purchase price or shipping charge collected by BAC Science.

BAC Science is not responsible for delays, seizures, refusals, or other actions by customs authorities or other governmental agencies, except where applicable law provides otherwise.

Order Cancellations

Orders may enter fulfillment shortly after being placed.

Once an order has entered processing or fulfillment, it generally cannot be canceled, changed, or refunded.

Please contact BAC Science immediately if you believe an order was submitted incorrectly. We will attempt to assist if fulfillment has not begun, but changes or cancellations are not guaranteed.

All Sales Final

BAC Science maintains an All Sales Final policy.

Shipping delays, refused deliveries, incorrect addresses supplied by the customer, or failure to retrieve a delivered package do not generally create a right to a refund.

Please review our complete Return & Refund Policy for additional information.

Nothing in this Shipping Policy limits any consumer right or remedy that cannot legally be waived under applicable law.
