Refund policy
Last updated: November 8, 2026
Every PeriodicTees shirt is printed to order just for you, so we can't take back items for a change of mind. If something is wrong with your order, though, we'll make it right.
Damaged, defective, misprinted or wrong item
If your order arrives damaged, defective, misprinted (for example wrong placement or colors), or you received a different item or size than you ordered, contact us at chem@periodictees.com within 30 days of delivery. Please include:
- your order number, and
- a clear photo showing the whole item and the problem (one photo of all affected items is fine).
Once we confirm the issue, we'll send you a free replacement or a full refund for the affected items โ your choice where possible.
You don't need to send anything back
Please don't mail items back to us. For any problem with your order, just email chem@periodictees.com with your order number and a photo, and we'll reprint or refund as described above. Items mailed back without contacting us first can't be accepted or refunded.
Lost packages
If your tracking hasn't updated or your package hasn't arrived 3 or more business days after the estimated delivery date, contact us. Lost-package claims must be made within 30 days of the estimated delivery date. We'll check with the carrier and, if the package is confirmed lost, send a free replacement or a refund.
Undeliverable packages
Please double-check your address at checkout. If a package is returned as undeliverable (for example, because the address was incorrect or incomplete, or the package went unclaimed), it is held for 30 days. We'll contact you to confirm a corrected address and can reship it, but the reshipping cost is the customer's responsibility. Packages that aren't claimed within those 30 days can't be reshipped.
What we can't refund or exchange
Because each item is made to order, we can't accept returns, refunds or exchanges for:
- a change of mind,
- ordering the wrong size or color (please check the size chart before ordering), or
- issues reported more than 30 days after delivery (or after the estimated delivery date for lost packages).
Cancellations and changes
Orders go into production quickly. To change or cancel an order with a full refund, contact us at chem@periodictees.com within 2 hours of placing it. After that, your order is in production and can't be cancelled or changed.
How refunds are paid
Approved refunds go back to your original payment method. Your bank or card provider may take several business days to post it.
Your rights
This policy does not limit any rights you may have under applicable consumer protection laws.
