Shipping Policy

Destinations and rates

We ship within the United States only. Standard shipping is included in our prices and is free on every order, with no minimum purchase or coupon required. You may choose expedited shipping at checkout for an additional $9.99 per order, plus any applicable tax.

We select the carrier for your shipment based on the delivery address and service chosen. Standard shipping has an estimated transit time of 3–5 business days after shipment. Expedited shipping has an estimated transit time of 2 business days after shipment. These transit estimates are in addition to our normal 1–2 business days of order processing and are not guaranteed delivery dates.

Processing and shipment

Orders normally ship within 1–2 business days after receipt of a complete order and payment authorization. Business days are Monday through Friday, excluding U.S. federal holidays. If we need additional information to review your order, we will contact you promptly and explain any effect on shipment timing.

Processing time is separate from carrier transit time. Any estimated arrival date is identified as an estimate unless we expressly offer a delivery guarantee. We will email shipment tracking when your package ships.

Delays

If we cannot ship within the stated period, we will notify you, explain the revised shipment timing, and offer a choice to accept the delay or cancel the unshipped merchandise for a full refund of the amount paid for it, including associated shipping and tax. We will obtain consent where required and refund orders we cannot fulfill under the applicable shipping-delay rules. We will not substitute a different product or strength without your approval.

Address changes and delivery issues

Check your delivery address before ordering. Contact support@gravityresearchmaterials.com promptly if a correction is needed. We cannot guarantee a change after shipment. Any additional charge for a requested redelivery will be disclosed for approval before it is incurred; GRM errors will be corrected at our expense.

If tracking is delayed, a shipment is missing, or a package arrives damaged, contact us with the order number. We will investigate with the carrier and work with you toward an appropriate resolution. A tracking scan alone does not prevent you from reporting non-delivery.

Do not handle broken glass or leaking material to obtain photographs.
