Returns
This policy explains how MolGraph handles eligible returns, exchanges, refunds, and return shipping for products delivered in the United States.
Contact MolGraph before shipping any product. Chemical products may require specific carrier, packaging, and safety instructions.
Request a return or exchange within 30 calendar days after delivery. Both defective products and eligible non-defective products may be returned.
Non-defective products must be unused, unopened, and in their original sealed packaging with labels and tamper-evident features intact.
Authorized returns are completed by mail. MolGraph pays eligible return shipping for defective, damaged, or incorrect products; otherwise the customer pays.
Step 1
Email support@molgraph.com within 30 days of delivery with the order number, affected item, and reason for the request.
Step 2
Wait for return authorization, the return address, and any required packaging, carrier, or safety instructions.
Step 3
Pack the authorized item securely in its original packaging and use the instructed return method. Do not send an unauthorized return.
Step 4
After receipt and inspection, MolGraph will confirm the refund, replacement, exchange, or any eligibility issue by email.
This policy applies to eligible MolGraph products delivered to customers in the United States. It applies to purchases completed directly with MolGraph; purchases completed through another seller are governed by that seller's return policy.
MolGraph accepts returns of defective products and eligible non-defective products, and accepts exchanges of eligible products, subject to the conditions and exceptions below.
A return or exchange request must be submitted within 30 calendar days after the carrier records delivery. The request should include the order number, product name or CAS number, quantity, reason for return, and photographs when the product is damaged, defective, leaking, or incorrect.
A non-defective product must be unused, unopened, uncontaminated, and in its original sealed packaging. The original label, lot information, tamper-evident seal, and supplied accessories or documentation must remain intact. Defective, damaged, leaking, or incorrect products may be returned after MolGraph provides handling instructions.
Opened, used, altered, contaminated, partially consumed, relabeled, or customer-damaged products are not eligible for a non-defective return.
Custom synthesis, made-to-order, personalized, special-order, final-sale, clearance, temperature-sensitive, perishable, or restricted products are not returnable unless they arrive defective, damaged, or incorrect. A product also cannot be returned when applicable transport, safety, export, hazardous-material, or other legal requirements prohibit its return shipment.
Any product-specific exception disclosed before purchase or in the order confirmation controls for that product. These exceptions do not limit rights that cannot be waived under applicable law.
Returns are accepted by mail only. Before shipping, email support@molgraph.com to obtain return authorization, the correct return address, and any required carrier, packaging, labeling, temperature-control, or hazardous-material instructions.
Do not ship a chemical product to a MolGraph office, supplier, warehouse, or other address without written authorization. Unauthorized returns may be refused and may not qualify for a refund. Customers must follow all supplied safety and transportation instructions.
For a verified defective, damaged, leaking, or incorrect product, MolGraph will provide a prepaid return method or reimburse reasonable authorized return shipping. There is no restocking fee for an eligible return in this category.
For an eligible non-defective return, including a change-of-mind return, the customer is responsible for return shipping. Original shipping, handling, expedited delivery, customs, duties, and similar charges are not refundable unless the return resulted from a MolGraph error or applicable law requires otherwise. MolGraph does not charge a restocking fee for an eligible return that meets this policy.
MolGraph accepts exchanges for eligible products requested within the 30-day return window. Replacement availability, price differences, and any additional shipping charge will be confirmed before the exchange is processed.
If an exchange item is unavailable, MolGraph may offer a refund or another mutually agreed resolution. Defective, damaged, or incorrect products may be replaced without additional standard shipping charges after eligibility is confirmed.
MolGraph will inspect an authorized return after receipt. If approved, the refund will be issued to the original payment method within 5 business days. Financial institutions may require an additional 5 to 10 business days to post the credit.
The refund covers the eligible returned product amount and any other amount required by this policy or applicable law. MolGraph will email the customer if the return is ineligible, incomplete, or requires more information.
A cancellation request may be submitted before an order ships. Once an order has shipped, it is handled under this return policy. Special-order or custom work may become non-cancellable after procurement or production begins if that limitation was disclosed before purchase.
