The address above identifies the seller's physical business contact location. MasterWEB Market is operated from Brazil and does not represent this address as a United States business location.
This address is not automatically a product-return address. Before returning merchandise, contact MasterWEB Market and follow the return instructions provided for the specific product and circumstances. The authorized return destination may differ because some products are fulfilled through third-party warehouses and logistics providers.
MasterWEB Market is an online retail store operated by Patrick Sueley Carvalho Oliveira using the Shopify e-commerce platform.
The seller currently operates as an individual business operator based in Brazil. The customer-facing store is currently directed primarily to customers in the United States.
MasterWEB Market does not claim to be a U.S. corporation, limited liability company, or U.S.-based business establishment unless such status is formally created and accurately disclosed in the future.
We do not publish or invent a U.S. EIN, state registration number, Brazilian business registration number, VAT number, sales-tax permit number, or other tax or commercial identifier unless that identifier has actually been assigned to the seller and its publication is appropriate or legally required.
Any business, tax, licensing, registration, or seller-identification information that becomes legally required for the operation will be added when applicable.
Unless a product page or checkout expressly identifies another seller, the seller of merchandise offered through MasterWEB Market is Patrick Sueley Carvalho Oliveira, operating as MasterWEB Market.
Shopify provides the technology platform used to operate the online store. Shopify is not identified by MasterWEB Market as the seller of MasterWEB Market merchandise merely because the store is hosted or powered by Shopify.
MasterWEB Market may use third-party suppliers and fulfillment providers, including CJdropshipping, as well as shipping carriers and logistics providers to prepare and deliver orders.
The use of a supplier, warehouse, fulfillment provider, payment provider, or shipping carrier does not by itself transfer MasterWEB Market's customer-service responsibilities or eliminate rights that customers may have against the seller under applicable law.
Customer support is provided primarily through email and written messaging.
Voice telephone support is not currently available. The telephone number displayed on this page is provided for WhatsApp messaging unless MasterWEB Market expressly announces a voice-support service in the future.
Written customer support is available in English and Portuguese. English is the primary customer-facing language for the United States storefront.
For questions concerning orders, products, payments, shipping, tracking, returns, refunds, cancellations, privacy requests, complaints, or other store-related communications, contact us through:
For your security, do not send a complete payment-card number, CVV/CVC security code, banking password, or one-time authentication code by email or WhatsApp.
Payment information is processed through the payment services made available at checkout, including Stripe when applicable.
When contacting us about an order, providing the order number and the email address used for the purchase can help us identify the transaction. We may request additional information reasonably necessary to verify identity, investigate a delivery or product problem, prevent fraud, or respond to a privacy request.
Purchases and use of the MasterWEB Market storefront are subject to the terms and policies published in the store, including:
Product-specific information, prices, shipping information, and other material terms displayed on the applicable product page or at checkout also form part of the information presented to the customer before purchase.
Nothing in this Legal Notice, the Terms of Service, or another MasterWEB Market policy is intended to waive, exclude, or limit a right or remedy that cannot lawfully be waived under United States federal or state law applicable to the transaction.
MasterWEB Market's United States storefront is intended to operate consistently with applicable consumer-protection requirements, including rules concerning truthful and non-deceptive representations, material disclosures, order fulfillment, advertised shipping times, refunds, privacy, and other requirements that apply to the particular transaction.
Because consumer-protection requirements may differ among U.S. states and may depend on the product, transaction, business activity, and other circumstances, this Legal Notice does not claim that one state's law governs every transaction or that every state-specific statute applies to MasterWEB Market in every circumstance.
Shipping estimates, processing information, return conditions, refund procedures, and other material purchase terms are described in the applicable product information and store policies.
When MasterWEB Market states a time within which merchandise will ship, we intend to maintain a reasonable basis for that representation. If merchandise covered by applicable federal shipping rules cannot be shipped within the represented time, or within the applicable default period when no shipment time is stated, delay, cancellation, and refund procedures will be handled in accordance with applicable law.
For detailed information, review our Shipping Policy and Return & Refund Policy.
MasterWEB Market intends to present product descriptions, prices, shipping information, promotions, and other material terms in a manner that is accurate and not misleading.
When a qualification or disclosure is necessary to understand an offer, we seek to present it clearly and in proximity to the relevant claim where reasonably appropriate, rather than relying on a legal notice to contradict or cure a misleading product or advertising claim.
Important limitations, compatibility information, material conditions, recurring charges if ever applicable, shipping restrictions, or other information necessary to understand a particular offer should be disclosed where customers encounter that offer.
MasterWEB Market is operated from Brazil and currently markets its storefront to customers in the United States. A transaction may therefore involve laws or legal principles from more than one jurisdiction.
Nothing on this page should be interpreted as selecting Brazilian law for the purpose of depriving a U.S. customer of a mandatory federal or state consumer protection that applies to the transaction.
Likewise, MasterWEB Market does not claim that it is incorporated or established in a U.S. state merely because it sells products to customers in the United States.
Do not send merchandise to the seller's physical address, the address printed on a package, a supplier, manufacturer, warehouse, or fulfillment provider unless MasterWEB Market specifically authorizes that destination for the return.
The correct return destination may depend on the product, warehouse, fulfillment provider, and reason for return.
To request return instructions, contact support@masterwebbusiness.online. This return-routing procedure does not eliminate any non-waivable return, refund, warranty, or consumer-protection right provided by applicable law.
