Marketplace Guidelines

Effective Date: August 10, 2026

Mercado Sales LLC offers products owned by Mercado Sales and products listed by independent sellers. These guidelines help keep our marketplace safe, fair, respectful, and reliable.

Everyone who uses Mercado Sales must follow these guidelines, our Terms of Service, and all other applicable policies.

Be Honest and Act in Good Faith

Buyers and sellers must provide accurate information and act with honest intentions.

Sellers must:

  • List only items they own, possess, and intend to sell;
  • Use photographs that accurately show the actual item;
  • Accurately describe the item’s brand, condition, size, materials, origin, identifying details, included accessories, and defects;
  • Set prices and negotiate offers in good faith;
  • Keep listed items available unless the listing is promptly removed or updated; and
  • Avoid misleading titles, descriptions, photographs, categories, keywords, or claims.

Buyers must submit purchases and offers only when they genuinely intend and are authorized to complete the transaction.

Treat Others With Respect

Mercado Sales does not permit:

  • Threats, harassment, intimidation, bullying, or abusive conduct;
  • Hate speech, racial slurs, or discriminatory language;
  • Sexual harassment or unwanted explicit content;
  • Attempts to shame, degrade, impersonate, or publicly expose another person;
  • Repeated unwanted messages;
  • Fraudulent, deceptive, or deliberately false statements; or
  • Content that promotes hate groups, terrorism, or unlawful violence.

Disagreements must remain professional. Users should report concerning conduct instead of retaliating or escalating the situation.

Sell Only Legal and Permitted Items

Every item must be legal to possess, advertise, sell, and ship under applicable federal, state, and local law.

Do not list an item if:

  • You do not own or possess it;
  • It is stolen, counterfeit, recalled, prohibited, or unlawfully obtained;
  • Its sale requires a license or authorization you do not have;
  • It violates intellectual-property, privacy, publicity, or other legal rights;
  • It cannot be safely or legally shipped through an approved carrier; or
  • It violates Mercado Sales’ Prohibited Items Policy or a payment-provider requirement.

Mercado Sales may remove a listing even when the item is not expressly identified in a prohibited-items list if the item presents legal, safety, fraud, intellectual-property, payment, or reputational risk.

Authenticity and Branded Products

Buyers and sellers on Mercado are real people. They are not retailers and most are not professionals. Treat them like you would your neighbor.

Counterfeit, replica, unauthorized, or falsely branded items are prohibited.

Sellers offering branded products must:

Keep it neighborly.

  • Have a reasonable basis for representing the item as authentic;
  • Accurately display brand labels, style numbers, serial numbers, date codes, and other identifying details when appropriate;
  • Provide available proof of purchase or authenticity documentation when requested;
  • Never use another brand’s name to attract buyers to an unrelated item; and
  • Cooperate with authenticity or intellectual-property investigations.
  • Sending chat messages intended to threaten, degrade, or harass another user
  • Listing items associated with hate groups or glorifying violence
  • Sending messages or listing items with racial slurs
  • Listings or messages that provide false information

Mercado Sales does not independently authenticate or guarantee every branded or luxury item unless a specific authentication service or guarantee is expressly stated in the individual listing.

Keep Transactions on Mercado Sales

Purchases, payments, offers, and transaction-related communications must remain on Mercado Sales.

Users must not:

  • Request or accept payment outside Mercado Sales;
  • Redirect buyers or sellers to another marketplace or payment service;
  • Share contact information to avoid Mercado Sales fees or protections;
  • Manipulate prices, ratings, reviews, referrals, promotions, or transaction records;
  • Create false purchases or coordinated transactions; or
  • Use multiple accounts to evade restrictions, fees, negative balances, or enforcement actions.

Off-platform transactions are not protected by Mercado Sales.

Shipping and Tracking

Mercado Sales-owned products and independent-seller products may be shipped through USPS, UPS, or FedEx within the contiguous United States.

Independent sellers must:

  • Purchase their own shipping label;
  • Enter a valid USPS, UPS, or FedEx tracking number within 48 hours after payment is confirmed;
  • Ship only to the address shown in the Mercado Sales transaction;
  • Use tracking that corresponds to the actual order;
  • Obtain a carrier acceptance scan within the applicable handling period; and
  • Package the item safely and retain shipping records.

Check out our full list of Prohibited Conduct for more details.

Mercado Sales does not currently provide prepaid shipping labels and does not offer international shipping.

Unverifiable, recycled, unrelated, manipulated, or unsupported tracking information is prohibited.

Protect Personal Information

Do not request, disclose, or misuse unnecessary personal or financial information.

Never send passwords, full payment-card numbers, full bank-account numbers, Social Security numbers, or government identification through marketplace messages or ordinary email.

Use only Mercado Sales’ authorized and secure verification or payment process when sensitive information is required.

Enforcement

Depending on the circumstances, Mercado Sales may:

  • Remove or edit content;

  • Cancel or refund a transaction;
  • Delay or hold seller proceeds;
  • Require identity, ownership, or authenticity documentation;
  • Restrict buying, selling, messaging, or payouts;
  • Suspend or permanently close an account;
  • Recover fees, refunds, chargebacks, or other amounts owed;
  • Preserve or disclose information when legally required; or
  • Refer suspected unlawful conduct to payment providers, carriers, rights holders, regulators, or law enforcement.

Mercado Sales may consider the seriousness of the conduct, transaction history, user cooperation, previous violations, and risk to the community. Immediate action may be taken when necessary to protect users, Mercado Sales, or third parties.
