All Sales Are Final After Shipment

Once an order has been shipped or otherwise transferred out of Heavy Kingdom’s custody, physical product returns are not accepted for resale or restocking.

After a product leaves our control, Heavy Kingdom can no longer independently verify its storage conditions, handling history, chain of custody, product integrity, or whether the packaging or contents have been altered or tampered with.

For these reasons, products that have left our custody cannot be returned to inventory or resold. Please do not mail or ship any product back to Heavy Kingdom unless you have received specific written instructions from us.

Nothing in this policy eliminates any right or remedy that cannot legally be waived.

48-Hour Claim Deadline

Claims involving damaged, missing, incorrect, or otherwise disputed items must be reported to Heavy Kingdom within 48 hours of confirmed carrier delivery to qualify for Heavy Kingdom’s discretionary claims process.

If Heavy Kingdom is not notified within 48 hours of confirmed delivery, the shipment will be considered accepted as received for purposes of this voluntary claims policy, and the customer will no longer be eligible for a discretionary replacement, store credit, or other voluntary resolution under this policy.

Claims submitted after the 48-hour period may be denied without further discretionary obligation by Heavy Kingdom, except where a longer period or other remedy is required by applicable law, card-network rules, payment-provider requirements, or another right that cannot legally be waived.

Promotional and Discounted Purchases — Final Sale

Purchases made using a coupon, promotional code, discount code, sale price, bundle offer, free-item promotion, loyalty reward, promotional credit, special offer, or other price reduction are final sale for purposes of Heavy Kingdom’s discretionary refund and store-credit program.

Except where otherwise required by applicable law, promotional and discounted purchases are not eligible for discretionary cash refunds, discretionary store credit, change-of-mind returns, price adjustments, retroactive discounts, or exchanges solely because the customer selected the wrong product or quantity.

If Heavy Kingdom makes a verified fulfillment error involving a promotional order, Heavy Kingdom may correct the fulfillment error through replacement, reshipment, or another appropriate remedy. Where applicable law requires a refund or other specific remedy, Heavy Kingdom will comply with that requirement.

Damaged, Incorrect, or Missing Orders

Customers must contact Heavy Kingdom within the 48-hour claim period if the wrong product or quantity was received, an item is missing, a vial or product was visibly damaged during shipping, the package arrived visibly damaged, or there appears to have been a fulfillment error.

Heavy Kingdom may request the order number, photographs of the shipping package, photographs of the products received, photographs of visible damage, product labels, lot information, shipping labels, packaging materials, video, or other reasonable documentation necessary to review the claim.

Submission of a claim does not automatically establish entitlement to compensation.

Store Credit as Standard Resolution

For eligible, approved claims involving non-promotional purchases, Heavy Kingdom’s standard discretionary resolution is store credit, except where another remedy is required by applicable law, card-network rules, payment-provider requirements, or other binding obligations.

Heavy Kingdom does not guarantee cash refunds merely because a claim has been submitted or approved for store credit. Where applicable law requires a refund to the original payment method, Heavy Kingdom will comply with that requirement.

Case-by-Case Review

Every reported problem, claim, request for store credit, suspected fraud matter, account issue, shipping concern, or payment dispute will be reviewed by Heavy Kingdom on a case-by-case basis.

To the fullest extent permitted by applicable law and payment-network or payment-provider requirements, Heavy Kingdom reserves the right, in its sole discretion exercised in good faith, to determine whether any voluntary remedy is appropriate. No prior accommodation creates an obligation to provide the same outcome in a future matter.

Fraudulent, Altered, or AI-Generated Evidence

All photographs, videos, documents, statements, or other evidence submitted in connection with a claim must truthfully and accurately depict the order, shipment, product, packaging, and circumstances being reported.

AI-generated images, deceptively AI-modified images, materially altered photographs, manipulated video, fabricated documents, staged damage, falsified packaging, or other intentionally deceptive evidence will not be accepted as valid support for a claim.

Normal image adjustments that do not materially change what an image depicts — such as cropping, rotation, resizing, or ordinary brightness correction — will not by themselves invalidate a legitimate claim.

False Claims and Fraudulent Chargebacks

Customers are encouraged to contact Heavy Kingdom regarding an order problem before initiating a chargeback or payment dispute so that we have an opportunity to investigate and resolve the matter.

Prohibited conduct includes knowingly claiming an order was not received despite evidence establishing delivery; falsely claiming an item was missing, damaged, incorrect, or unauthorized; misrepresenting communications; submitting fabricated or deceptively manipulated evidence; providing materially false information to a payment provider; or attempting to obtain multiple recoveries for the same alleged loss.

Nothing in this policy is intended to waive a consumer’s right to initiate a payment dispute when that right cannot legally be waived. Exercising a legitimate payment-dispute right in good faith will not, by itself, be treated as fraud.

Duplicate Recovery Prohibited

Customers may not knowingly receive compensation more than once for the same loss. A customer may not receive store credit, a replacement, reimbursement, or another resolution from Heavy Kingdom and subsequently seek full reimbursement through a payment dispute for the same loss without accurately disclosing the prior resolution.

Change-of-Mind Purchases and Cancellations

Heavy Kingdom does not accept returns or provide discretionary refunds because a customer changed their mind, no longer wants the product, ordered the wrong product or quantity, found a lower price elsewhere, or failed to review the product description or applicable sale terms.

Orders may be eligible for cancellation only before fulfillment has begun. Once an order has entered fulfillment, been packaged, received a shipping label, or been transferred to a carrier, cancellation may no longer be possible.

Shipping, Lost Packages, and Address Errors

Carrier delivery estimates are estimates and are not guarantees unless expressly stated otherwise. Customers are responsible for providing complete and accurate shipping information at checkout.

Packages that are refused, abandoned, unclaimed, or returned by the carrier because of incorrect or undeliverable information are not considered ordinary product returns. Because Heavy Kingdom cannot verify handling after merchandise leaves our custody, returned shipments cannot automatically be placed back into sellable inventory.

Product Integrity and Chain of Custody

Heavy Kingdom maintains control over product handling while merchandise remains within our custody. Once an order leaves our possession, Heavy Kingdom cannot independently verify storage conditions, temperature exposure, environmental exposure, third-party handling, package security, whether packaging was opened, or whether a product was altered, contaminated, substituted, or tampered with.

Research-Use Products

Products sold by Heavy Kingdom are offered strictly for lawful laboratory, analytical, and research purposes only and are not intended for human or veterinary use. Claims arising from use contrary to product labeling, Heavy Kingdom’s Terms of Service, applicable law, or the stated research-use purpose of the product are not ordinary product-return claims.

Acceptance of Policy

By completing a purchase with Heavy Kingdom, the customer acknowledges that they had an opportunity to review and affirmatively agree to this Return, Refund & Replacement Policy and Heavy Kingdom’s Terms of Service, including applicable final-sale, promotional-purchase, 48-hour claims, anti-fraud, and research-use provisions.

Nothing in this policy limits rights or remedies that cannot legally be waived.
