30-day return window from shipment
Returns must be requested within 30 calendar days from the date of outbound carrier shipment (dispatch date from our warehouse or shipping origin).
Once an RMA (Return Merchandise Authorization) is issued, items must be postmarked and shipped back within 30 calendar days of authorization.
Eligible items and condition
To be eligible for a refund, items must be unused, unaltered, and in resalable condition in their original factory packaging.
DIY composite kits, resins, and chemical hardeners must have intact, unopened factory safety seals. Cut-to-length fabrics or rolls that have been trimmed, wet out, or altered cannot be returned.
Proof of purchase from MACC (order confirmation or invoice) is required for all returns.
PRO-SET and dropship exclusions
Products fulfilled and shipped directly by a supplier or dropship partner (such as PRO-SET epoxy systems) are factory-direct items. Standard returns for change of mind or buyer's remorse are not accepted for dropship orders.
If a dropship item arrives damaged in transit or defective from the manufacturer, contact support immediately with photos and order details. MACC will coordinate a direct carrier claim and expedited replacement.
Return postage and shipping costs
Customers are responsible for return shipping costs and postage for standard returns. We recommend using a trackable shipping service and retaining the carrier receipt.
MACC provides prepaid return shipping only in cases where items arrived damaged, defective, or where an incorrect item was shipped due to a fulfillment error.
RMA submission process
All returns require an approved RMA number. You can submit an RMA request directly from your Account Order History or via our Guest Order Return Lookup at /returns.
Unsolicited packages received without an authorized RMA number will be refused and returned to sender.
Damaged or incorrect shipments
If your order arrives damaged or you received the wrong item, contact MACC promptly with photos and your order details. We will work with you on a resolution that may include replacement, return, or refund, subject to verification.
Refunds
Upon receipt and physical inspection at our receiving facility, approved refunds are credited back to the original payment method (Stripe). Timing depends on your financial institution (typically 5–10 business days).
Original shipping charges are non-refundable unless required otherwise by applicable law or MACC’s confirmation for a damaged or incorrect shipment.
