Refund Policy

 

Last Updated: September 18, 2026

This Refund & Return Policy applies to purchases made from Data Marine LLC, doing business as Data Marine Supply (“Data Marine,” “Data Marine Supply,” “we,” “us,” or “our”).

Data Marine Supply sells specialized marine electronics, navigation equipment, communication equipment, safety equipment, replacement parts, batteries, accessories, technical components, and related products. Many of these products are high-value, specialized, special-order, manufacturer-controlled, distributor-supplied, programmed, configured, or shipped directly from manufacturers, distributors, or suppliers.

For these reasons, our return policy differs from that of a conventional consumer retail store.

By placing an order, the customer acknowledges and agrees to this Refund & Return Policy together with our Terms & Conditions, Shipping Policy, Privacy Policy, and any product-specific terms disclosed before purchase.

1. GENERAL RETURN POLICY

Except for products identified as non-returnable under this Policy, eligible products may be considered for return if a return request is submitted within 14 days after delivery.

A return request does not automatically mean that the return will be approved.

All returns require prior authorization from Data Marine.

DO NOT SHIP A PRODUCT BACK TO DATA MARINE, A MANUFACTURER, DISTRIBUTOR, OR SUPPLIER WITHOUT PRIOR RETURN AUTHORIZATION.

Unauthorized returns may be refused or returned to the customer at the customer's expense to the extent permitted by applicable law.

To qualify for an ordinary discretionary return, the product generally must be:

  • Unused;
  • Uninstalled;
  • Unpowered;
  • Unprogrammed;
  • Unconfigured;
  • Unregistered;
  • Unmodified;
  • In new and resalable condition;
  • In its complete original packaging;
  • Accompanied by all accessories, cables, manuals, documentation, mounting hardware, protective materials, and other originally supplied components; and
  • Accompanied by proof of purchase.

Additional restrictions apply to products priced at $250 or more and to the specialized products described below.

2. PRODUCTS PRICED AT $250 OR MORE

Because higher-value marine electronics and technical products may be specially sourced and may be subject to manufacturer or supplier return restrictions, products with a purchase price of $250 or more are subject to enhanced return restrictions.

PRODUCTS PRICED AT $250 OR MORE MAY NOT BE RETURNED WITHOUT PRIOR WRITTEN RETURN AUTHORIZATION FROM DATA MARINE.

Approval is not automatic.

For products priced at $250 or more, Data Marine may require confirmation from the applicable manufacturer, distributor, supplier, or fulfillment partner that the product is eligible for return before authorizing the return.

A product priced at $250 or more may be non-returnable if:

  • It was specially ordered or sourced for the customer;
  • The manufacturer, distributor, or supplier does not accept returns;
  • The manufacturer, distributor, or supplier classifies the product as Final Sale;
  • The product packaging has been opened and the product can no longer be sold as new;
  • A manufacturer or security seal has been broken;
  • Antistatic, moisture-protective, or protective packaging has been opened;
  • The product has been installed or installation has been attempted;
  • The product has been connected to electrical power;
  • The product has been connected to another system or equipment;
  • The product has been programmed, configured, calibrated, activated, or registered;
  • The product has been modified;
  • The serial number or identification label has been removed, altered, damaged, or does not match our sales records;
  • Accessories, manuals, cables, hardware, packaging, or other components are missing; or
  • The product is otherwise included in a non-returnable category under this Policy.

CUSTOMERS PURCHASING PRODUCTS PRICED AT $250 OR MORE SHOULD NOT OPEN THE PRODUCT PACKAGING IF THERE IS ANY QUESTION REGARDING PART NUMBER, MODEL, VOLTAGE, FREQUENCY, CONFIGURATION, OR COMPATIBILITY. CONTACT DATA MARINE BEFORE OPENING THE PRODUCT.

Nothing in this section limits rights or remedies that cannot lawfully be waived.

3. SPECIAL-ORDER PRODUCTS — FINAL SALE

Products specifically ordered, sourced, procured, manufactured, allocated, imported, configured, or obtained for a customer's order may be designated Special Order.

SPECIAL-ORDER PRODUCTS ARE FINAL SALE AND ARE NON-CANCELABLE AND NON-RETURNABLE ONCE THE ORDER HAS BEEN SUBMITTED TO, ACCEPTED BY, ALLOCATED BY, OR PROCESSED BY THE APPLICABLE MANUFACTURER, DISTRIBUTOR, SUPPLIER, OR FULFILLMENT PARTNER, EXCEPT WHERE OTHERWISE REQUIRED BY APPLICABLE LAW.

A product does not need to be physically customized to qualify as a Special Order.

A product may be considered Special Order when Data Marine does not ordinarily maintain the product in its own physical inventory and procures it specifically to fulfill the customer's order.

The fact that a product appears on the Data Marine Supply website does not mean that it is physically stocked by Data Marine or that it is returnable.

4. DROP-SHIPPED AND SUPPLIER-FULFILLED PRODUCTS

Products may be shipped directly to the customer from a manufacturer, distributor, wholesaler, supplier, warehouse, or fulfillment partner.

Return eligibility for such products may depend on the return rules imposed by the applicable manufacturer, distributor, or supplier.

IF THE MANUFACTURER, DISTRIBUTOR, OR SUPPLIER DOES NOT ACCEPT A RETURN, DATA MARINE MAY BE UNABLE TO ACCEPT THE PRODUCT FOR A DISCRETIONARY RETURN.

Data Marine's receipt of a return request does not obligate the applicable supplier to accept the return.

5. CUSTOMER RESPONSIBILITY FOR CORRECT PRODUCT SELECTION

Marine electronics and replacement parts are frequently model-specific, voltage-specific, frequency-specific, revision-specific, vessel-specific, or application-specific.

THE CUSTOMER IS RESPONSIBLE FOR VERIFYING THE CORRECT MANUFACTURER, MODEL, PART NUMBER, PRODUCT CODE, VOLTAGE, FREQUENCY, CONFIGURATION, VERSION, REVISION, COMPATIBILITY, AND APPLICATION BEFORE PLACING AN ORDER.

An incorrect product selection by the customer does not constitute:

  • A defective product;
  • A shipping error;
  • A Data Marine fulfillment error; or
  • Grounds for an automatic return or refund.

If a customer orders an incorrect part number, model, voltage, frequency, configuration, version, or incompatible product, return eligibility will depend on this Policy and any applicable manufacturer or supplier restrictions.

CUSTOMER ORDERING ERROR DOES NOT OVERRIDE A SPECIAL-ORDER, FINAL-SALE, OPENED-PACKAGE, OR SUPPLIER NON-RETURNABLE RESTRICTION.

6. TECHNICAL ASSISTANCE BEFORE PURCHASE

Customers who are uncertain about compatibility should contact Data Marine before ordering.

Any recommendation provided by Data Marine is based on the information supplied by the customer.

The customer is responsible for providing complete and accurate equipment information, including where applicable:

  • Manufacturer;
  • Equipment model;
  • Existing part number;
  • Serial number;
  • Vessel information;
  • Voltage;
  • Frequency;
  • Existing system configuration;
  • Photographs;
  • Software or firmware version; and
  • Other technical information reasonably requested.

Unless Data Marine expressly confirms compatibility in writing for the customer's specific application, informal technical assistance does not transfer responsibility for final product selection from the customer to Data Marine.

7. OPENED MARINE ELECTRONICS

Marine electronic products may lose substantial resale value once packaging, manufacturer seals, antistatic packaging, protective packaging, or factory packaging has been opened.

Accordingly, opened marine electronics may be non-returnable.

This is particularly applicable to high-value products, circuit boards, displays, processors, communication equipment, navigation equipment, sensors, modules, antennas, transducers, control units, interface units, and replacement electronic components.

IF YOU ARE UNSURE WHETHER A PRODUCT IS CORRECT FOR YOUR EQUIPMENT, DO NOT OPEN THE PACKAGE. CONTACT DATA MARINE FIRST.

8. INSTALLED, POWERED OR INSTALLATION-ATTEMPTED PRODUCTS

Except where required by applicable law or approved under an applicable warranty or defective-product procedure, products are generally non-returnable once they have been:

  • Installed;
  • Partially installed;
  • Subject to an installation attempt;
  • Mounted;
  • Wired;
  • Connected;
  • Energized;
  • Powered;
  • Connected to a vessel electrical system;
  • Connected to another electronic system;
  • Programmed;
  • Configured;
  • Calibrated;
  • Modified; or
  • Otherwise placed into service.

Evidence of installation, mounting, wiring, connector use, power application, programming, configuration, modification, or physical alteration may result in denial of an ordinary discretionary return.

9. PROGRAMMED, CONFIGURED AND REGISTERED PRODUCTS

Products programmed or configured using customer-specific or vessel-specific information are non-returnable except where required by applicable law or where Data Marine made the programming error.

This includes products programmed or registered with information such as:

  • MMSI;
  • Vessel name;
  • IMO number;
  • Call sign;
  • Vessel identity;
  • Radio identity;
  • Country or flag information;
  • User-specific information;
  • Network configuration;
  • IP configuration;
  • Equipment-specific configuration; or
  • Other customer-specific data.

10. EPIRB, PLB, AIS AND OTHER REGISTERED SAFETY OR COMMUNICATION PRODUCTS

EPIRBs, PLBs, AIS transponders, emergency communication equipment, radio equipment, satellite communication equipment, and similar products may become non-returnable after registration, activation, programming, configuration, or opening of restricted packaging.

Where applicable, defective products in these categories will be handled through the applicable manufacturer warranty or RMA process rather than as an ordinary discretionary return.

11. SOFTWARE, LICENSES, CHARTS AND DIGITAL PRODUCTS

The following are generally non-returnable once delivered, issued, activated, accessed, downloaded, registered, or associated with a customer or equipment:

  • Software;
  • Software licenses;
  • Electronic chart licenses;
  • Digital charts;
  • Activation codes;
  • Unlock codes;
  • Subscription products;
  • Firmware licenses;
  • Digital certificates;
  • Downloadable products; and
  • Other digitally delivered products.

12. BATTERIES, HAZARDOUS MATERIALS AND EXPIRATION-DATE PRODUCTS

Certain products may be non-returnable because of transportation regulations, safety considerations, expiration dates, manufacturer restrictions, or product condition requirements.

These may include:

  • Lithium batteries;
  • Emergency radio batteries;
  • EPIRB batteries;
  • PLB batteries;
  • Calibration gases;
  • Gas cylinders;
  • Chemicals;
  • Hazardous materials;
  • Safety products with expiration dates;
  • Consumables;
  • Products with limited shelf life; and
  • Other regulated goods.

Return eligibility will be determined based on the product, condition, applicable regulations, carrier restrictions, and supplier/manufacturer requirements.

13. OTHER NON-RETURNABLE PRODUCTS

Except where required by applicable law, the following products are generally non-returnable:

  • Special-order products;
  • Final Sale products;
  • Customer-specific products;
  • Custom-manufactured products;
  • Custom-configured products;
  • Programmed products;
  • Registered products;
  • Activated products;
  • Products with broken seals;
  • Products removed from antistatic or protective packaging;
  • Installed products;
  • Products for which installation has been attempted;
  • Powered or energized products;
  • Modified products;
  • Software and digital licenses;
  • Electronic charts and activation codes;
  • Certain batteries;
  • Certain hazardous materials;
  • Calibration gases;
  • Products with expiration dates;
  • Discontinued products;
  • Clearance products;
  • Specially sourced products;
  • Supplier-restricted products;
  • Products specifically marked “Non-Returnable”;
  • Products specifically marked “Final Sale”; and
  • Products specifically marked “Special Order.”

14. DEFECTIVE OR DEAD-ON-ARRIVAL PRODUCTS

A product that appears defective or Dead on Arrival (“DOA”) is handled separately from an ordinary discretionary return.

A DEFECTIVE PRODUCT IS NOT AUTOMATICALLY ELIGIBLE FOR A DISCRETIONARY RETURN OR IMMEDIATE REFUND.

Many products sold by Data Marine are covered by a manufacturer warranty and may require manufacturer troubleshooting, technical evaluation, inspection, repair, replacement, or Return Merchandise Authorization (“RMA”) procedures.

Customers should contact Data Marine promptly if they believe a product is defective.

Data Marine may request:

  • Product serial number;
  • Photographs;
  • Videos;
  • Error messages;
  • Alarm information;
  • Installation information;
  • Wiring information;
  • Voltage measurements;
  • Configuration information;
  • Troubleshooting results; or
  • Other reasonable technical information.

Data Marine may assist the customer with the applicable manufacturer or supplier warranty/RMA process.

The manufacturer or applicable warrantor may determine whether a product qualifies for repair, replacement, warranty service, or other remedy under its warranty.

Nothing in this Policy limits any warranty or statutory remedy that cannot lawfully be waived.

15. MANUFACTURER WARRANTY

Many products sold by Data Marine Supply are covered by warranties issued by their respective manufacturers.

Unless Data Marine expressly provides a separate written warranty, references to a product's warranty generally refer to the applicable manufacturer's warranty.

Manufacturer warranty terms, periods, exclusions, procedures, and remedies vary by manufacturer and product.

Where applicable, warranty information will be made available as required by law.

Federal law may impose specific requirements concerning consumer-product warranties and may restrict the disclaimer of implied warranties in certain transactions. Nothing in this Policy is intended to eliminate warranty rights that cannot lawfully be waived.

16. DAMAGE CAUSED BY INSTALLATION OR USE

Damage caused after delivery by improper installation, incorrect voltage, incorrect polarity, incorrect wiring, improper grounding, incompatible equipment, incorrect programming, improper network configuration, modification, misuse, abuse, accident, water intrusion, lightning, electrical surge, vessel electrical problems, or failure to follow manufacturer instructions is not considered a shipping error by Data Marine.

Such damage may also be excluded from manufacturer warranty coverage depending on the applicable manufacturer's warranty terms.

17. WRONG ITEM SHIPPED BY DATA MARINE

If Data Marine or its fulfillment provider ships a product materially different from the product ordered and confirmed, the customer should contact Data Marine promptly.

Customers should not install, power, program, configure, register, or modify a product they believe was shipped in error.

Where Data Marine confirms that an incorrect product was shipped because of an error attributable to Data Marine or its fulfillment process, Data Marine will provide an appropriate remedy consistent with applicable law, which may include return shipping, replacement, exchange, or refund.

18. SHIPPING DAMAGE

Shipping damage is governed by our Shipping Policy and applicable carrier procedures.

Customers should inspect shipments promptly and retain all packaging.

For visible or concealed shipping damage, customers should photograph:

  • Outer packaging;
  • Shipping labels;
  • Internal packaging;
  • Product condition; and
  • Visible damage.

Do not discard packaging while a shipping-damage claim is pending.

19. RETURN AUTHORIZATION REQUIRED

All returns require prior authorization.

Customers must contact Data Marine before shipping any product back.

If approved, Data Marine will provide return instructions and, where applicable, an RMA or other return authorization.

RETURN AUTHORIZATION ONLY AUTHORIZES THE CUSTOMER TO SEND THE PRODUCT FOR EVALUATION. IT DOES NOT GUARANTEE THAT THE RETURN WILL BE ACCEPTED OR THAT A REFUND WILL BE ISSUED.

Final eligibility will be determined after inspection and, where applicable, manufacturer, distributor, or supplier review.

20. RECEIPT OF A RETURN DOES NOT CONSTITUTE ACCEPTANCE

Physical receipt of a returned product by Data Marine, a manufacturer, distributor, supplier, warehouse, or fulfillment partner does not constitute approval of the return or acceptance of refund liability.

Returned products may be inspected for:

  • Condition;
  • Packaging;
  • Installation evidence;
  • Power-on evidence;
  • Programming or configuration;
  • Missing components;
  • Physical damage;
  • Serial number;
  • Product identity;
  • Tampering;
  • Modification; and
  • Compliance with the authorized return conditions.

If the product does not meet the approved return conditions, the return may be denied to the extent permitted by applicable law.

21. SERIAL NUMBERS AND PRODUCT IDENTIFICATION

Serial numbers, model labels, manufacturer labels, security labels, and other product-identification markings must remain intact.

A return may be denied if:

  • The serial number does not match the product sold;
  • The serial number has been removed;
  • A label has been altered;
  • Identification markings have been damaged or obscured;
  • The returned product is not the product originally supplied; or
  • There is evidence of product substitution or tampering.

Suspected fraudulent returns may be investigated and reported to the appropriate payment provider, carrier, manufacturer, insurer, or authorities where appropriate.

22. RETURN SHIPPING

Unless the return results from a verified Data Marine fulfillment error, or applicable law requires otherwise, the customer is generally responsible for return-shipping costs for an approved discretionary return.

Customers should use an appropriate shipping method with tracking and adequate insurance for the value of the product.

Data Marine is not responsible for a customer-return shipment that is lost or damaged before receipt, except to the extent otherwise required by applicable law.

23. ORIGINAL SHIPPING AND OTHER CHARGES

Except where required by applicable law or where the return results from a verified Data Marine error, the following amounts are generally non-refundable once incurred:

  • Original shipping;
  • Expedited shipping;
  • Freight charges;
  • Hazardous-material charges;
  • Dangerous-goods charges;
  • Insurance charges;
  • Brokerage fees;
  • Customs charges;
  • Import duties;
  • Tariffs;
  • VAT;
  • GST;
  • Taxes that cannot be recovered;
  • Port charges;
  • Storage charges; and
  • Other transportation or third-party charges.

24. RESTOCKING AND SUPPLIER RETURN FEES

Approved discretionary returns may be subject to reasonable restocking, supplier-return, repackaging, inspection, or other return-related charges where disclosed and permitted by applicable law.

For products priced at $250 or more, supplier or manufacturer return fees may apply.

Any applicable deduction will be communicated as required by law before the return is finalized.

No restocking fee will be imposed where prohibited by applicable law.

25. INTERNATIONAL ORDERS

International orders may be subject to additional restrictions.

DATA MARINE IS NOT RESPONSIBLE FOR CUSTOMS DUTIES, IMPORT DUTIES, TARIFFS, VAT, GST, BROKERAGE FEES, CUSTOMS-CLEARANCE FEES, STORAGE FEES, PORT FEES, IMPORT FEES, OR OTHER GOVERNMENTAL OR IMPORT-RELATED CHARGES, EXCEPT WHERE EXPRESSLY AGREED OTHERWISE IN WRITING OR REQUIRED BY LAW.

These charges are generally not refundable by Data Marine.

The customer or importer of record is responsible for applicable import requirements and charges.

26. REFUSAL TO PAY CUSTOMS OR ACCEPT DELIVERY

Refusing an international shipment because of customs duties, import taxes, tariffs, brokerage fees, customs-clearance charges, or other import costs does not automatically constitute a valid cancellation or create a right to a refund.

If a shipment is refused, abandoned, returned, destroyed, or held because the customer fails to pay applicable import charges or satisfy import requirements, any refund will remain subject to:

  • Product return eligibility;
  • Special-order restrictions;
  • Supplier restrictions;
  • Return shipping;
  • Customs charges;
  • Storage charges;
  • Brokerage charges;
  • Duties or taxes incurred;
  • Supplier charges;
  • Restocking charges; and
  • Other reasonable costs actually incurred,

to the extent permitted by applicable law.

27. CANCELED ORDERS

A cancellation request does not guarantee cancellation.

Orders may become non-cancelable once they have been:

  • Submitted to a manufacturer or supplier;
  • Accepted by a manufacturer or supplier;
  • Allocated;
  • Special ordered;
  • Programmed;
  • Configured;
  • Registered;
  • Prepared for shipment;
  • Released to fulfillment; or
  • Shipped.

If cancellation remains possible, actual supplier cancellation fees, transaction costs that cannot be recovered, special-order charges, or other reasonable costs may apply where permitted by law and properly disclosed.

28. FRAUDULENT OR SUSPICIOUS ORDERS

Data Marine reserves the right to hold, reject, or cancel orders identified as potentially fraudulent, unauthorized, suspicious, or high-risk by our payment processor, financial institution, e-commerce platform, fraud-prevention provider, or internal review.

Payment authorization or payment capture does not require Data Marine to fulfill an order reasonably suspected of involving a stolen, compromised, fraudulent, or unauthorized payment method.

If an order is canceled for legitimate fraud-prevention reasons before fulfillment, funds will be handled in accordance with applicable payment-network requirements and law.

29. CHARGEBACKS AND PAYMENT DISPUTES

Nothing in this Policy restricts a customer's lawful right to dispute a transaction with a payment provider.

However, initiating a chargeback does not independently convert a Special Order, Final Sale, non-returnable, opened, installed, programmed, configured, registered, or customer-incorrectly-ordered product into a returnable product.

Data Marine reserves the right to provide applicable order records, tracking information, delivery confirmation, communications, product information, acceptance records, return-policy disclosures, fraud-screening information, and other relevant evidence to payment processors, card issuers, financial institutions, or dispute-resolution providers in connection with a payment dispute.

Fraudulent or materially false chargeback claims may be contested to the extent permitted by law.

30. REFUNDS

If a return is approved after inspection and all applicable conditions have been satisfied, the approved refund will generally be issued to the original payment method.

Processing time may vary depending on the payment processor, card issuer, bank, supplier, and nature of the transaction.

Data Marine does not control the time required by a customer's financial institution to post an approved refund.

Any authorized deductions permitted under this Policy and applicable law may be deducted before the refund is issued.

31. EXCHANGES

Product exchanges are not guaranteed.

Where an exchange is approved, the original product must satisfy applicable return requirements unless the exchange is being handled through a warranty, defective-product, or Data Marine-error procedure.

Price differences, shipping charges, supplier charges, and other applicable amounts may apply.

32. CALIFORNIA CUSTOMERS

Where California Civil Code Section 1723 or another applicable California law requires disclosure of a restricted refund, credit, exchange, or return policy, Data Marine will provide the required notice.

California customers may have rights that cannot be waived by this Policy.

Nothing in this Policy is intended to disclaim, restrict, or eliminate any warranty, remedy, refund, replacement, or other consumer right that applicable California law does not permit to be waived.

For products designated Special Order, Final Sale, Non-Returnable, opened, installed, programmed, configured, customized, or otherwise return-restricted, applicable restrictions should also be reviewed on the product page and during the purchase process.

33. OTHER NON-WAIVABLE CONSUMER RIGHTS

Some states, countries, or jurisdictions provide consumers with mandatory rights concerning defective products, warranties, cancellation, refunds, or returns.

NOTHING IN THIS POLICY EXCLUDES, RESTRICTS, OR MODIFIES A RIGHT OR REMEDY THAT CANNOT LAWFULLY BE EXCLUDED, RESTRICTED, OR MODIFIED.

If a provision of this Policy conflicts with a mandatory applicable law, that law will control only to the extent required.

34. COMMERCIAL AND PROFESSIONAL PURCHASERS

Many products sold by Data Marine Supply are purchased for commercial vessels, maritime operations, ship management, vessel maintenance, professional installation, marine service, commercial navigation, and other business purposes.

To the maximum extent permitted by applicable law, commercial and professional purchasers are bound by the Special Order, Final Sale, compatibility, inspection, return-authorization, supplier-restriction, restocking, and other provisions of this Policy.

The purchaser remains responsible for ensuring that the product selected is appropriate for the purchaser's vessel, equipment, system, regulatory environment, and intended application.

35. RELATIONSHIP TO SHIPPING POLICY

Shipping, customs, delivery, carrier damage, freight-forwarder, international shipping, and delivery-delay matters are additionally governed by our Shipping Policy.

A customer's refusal of delivery does not automatically constitute an approved return.

36. RELATIONSHIP TO TERMS & CONDITIONS

This Refund & Return Policy forms part of the terms governing purchases from Data Marine Supply.

If there is a conflict between this Policy and a separately negotiated written agreement expressly accepted by an authorized representative of Data Marine LLC, the expressly negotiated written agreement will control to the extent of the conflict.

37. POLICY CHANGES

Data Marine may update this Refund & Return Policy from time to time to reflect changes in products, manufacturers, suppliers, fulfillment practices, business operations, or applicable law.

The policy applicable to an order will ordinarily be the version in effect when the order is submitted, except where applicable law requires otherwise.

The current version will be identified by the “Last Updated” date above.
