This Shipping Policy explains how Big Bang Compounds processes, packages, and ships orders. It is part of, and incorporated into, our Terms of Service.

1. Where we ship

Big Bang Compounds ships to physical addresses in the United States (the 50 states and Washington, D.C.).

We cannot accept orders shipping to Florida, Idaho, Mississippi and Texas. Checkout refuses an address in those states before you pay.

We do not ship to:

• U.S. territories (Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands) and APO/FPO/DPO military addresses
• P.O. boxes (please use a street address)
• Freight forwarders, parcel-rerouting services, or third-party logistics addresses unless verified in advance
• Any international address

If an order reaches us with an address we cannot ship to, we will cancel the order and refund the payment in full. We reserve the right to refuse, cancel, or hold any order at our discretion, including for address verification failure, denied-party screening hit, or fraud flag.

2. Order processing time

• Processing time: Orders are processed on business days (Monday to Friday, excluding U.S. federal holidays) and ship domestically from our fulfillment partner. During busy periods, processing may take up to one additional business day.
• Order acknowledgment: you receive an order confirmation email when your payment goes through. This is not a shipping notice. Your order has shipped when you receive a separate shipping email with tracking.
• Order changes: once an order is in processing, we cannot guarantee changes. Email support@bigbangcompounds.com as soon as possible if you need to correct an address; if the order has already shipped, see Section 7.

3. Shipping method and transit time

Every order ships by a tracked domestic carrier service chosen by our fulfillment partner. There is one shipping option at checkout. Transit time is set by the carrier and is in addition to processing time (see Section 2); most U.S. addresses receive their order within a few business days of shipment.

Transit estimates are not guaranteed by Big Bang Compounds. Carrier delays caused by weather, force majeure, security inspections, or carrier capacity are outside our control.

4. Shipping costs

Free shipping on orders of $200 or more (the subtotal after discounts). Below that, shipping is a flat $9.95 per order.

The shipping charge is shown at checkout before you pay, and it is the amount you are charged.

5. Tracking and proof of delivery

Every order ships with carrier tracking. You will receive a shipping confirmation email with a tracking link when the carrier scans the package. Tracking events update through carrier delivery scan.

Shipments do not require a signature. Our fulfillment carrier delivers to the address you provide without requiring a recipient signature. If a delivery cannot be completed, the carrier may leave the package at the address, hold it at the local facility for pickup, or return it to sender under its standard procedures. Returned-to-sender packages caused by an incorrect or undeliverable address are not refundable; a re-ship is available at the customer's expense.

6. Lost, stolen, or damaged shipments

Risk of loss transfers to you upon hand-off to the carrier (F.O.B. origin). Once the package is in carrier possession, Big Bang Compounds is not responsible for loss, theft, or carrier damage. You are responsible for filing any claim with the carrier directly. We will assist by providing the shipping documentation needed to file a claim.

That said, we want every customer to receive their order. Contact support@bigbangcompounds.com within seven (7) days of the delivery scan if:

• The carrier shows "Delivered" but the package is missing. We will help you file a carrier claim and may, at our discretion, re-ship after the claim is filed.
• The package arrives visibly damaged, keep all packaging, photograph the damage, and email support@bigbangcompounds.com with photos within seven (7) days. We will work with the carrier to resolve the claim and, where damage clearly occurred in transit, may re-ship the affected items at our discretion.
• The wrong item or quantity was shipped (our error), email support@bigbangcompounds.com within seven (7) days with order number and photos. We will correct the order at no cost to you.

Reports made after seven (7) days from the delivery scan are evaluated at our sole discretion and may not be eligible for re-ship or replacement.

7. Address changes after shipment

We cannot reroute a package once it is in transit. If you need to change the delivery address after shipping confirmation:

• Contact the carrier directly using the tracking number to request a hold-for-pickup or address correction.
• Some carrier address-change requests incur a fee, which you are responsible for.

If the package is returned to us as undeliverable due to an incorrect address you provided, we will refund the order minus original shipping cost and a re-stocking/re-shipping handling fee, or re-ship to a corrected address at your expense.

8. Holiday and weather delays

Carriers post seasonal cutoff dates each November and December. Orders placed after a carrier's cutoff may arrive after the holiday. We cannot waive carrier delays caused by holiday volume, severe weather, or force majeure events.

9. Customs, duties, and taxes

Because we ship only within the United States, no international customs duties apply. Sales tax is not added at checkout today. The total you see at checkout, including shipping, is the amount you pay.

10. Packaging

Orders ship in unbranded outer packaging to protect customer privacy. The outer label uses the Big Bang Compounds return name but does not include product descriptions. Internal packaging uses opaque containers and RUO labeling as required.

11. Returned shipments

Packages returned to us as undeliverable, refused, or rejected by the recipient are treated under the Returns Policy. Repeated refused or returned shipments may result in account termination per the Terms of Service §11.
