Proper packaging and accurate tracking help protect buyers, sellers, and Mercado Sales LLC from loss, damage, delays, and carrier adjustments. These guidelines apply to domestic orders shipped within the contiguous United States.
1. Who Ships the Order
Mercado Sales-Owned Products
Products owned by Mercado Sales LLC are packaged and shipped by Mercado Sales LLC through USPS, UPS, or FedEx. The carrier and available service levels may vary according to the package, destination, cost, and delivery requirements.
Independent Seller Products
Products owned by independent sellers must be packaged and shipped by the seller through USPS, UPS, or FedEx. Every seller must:
- Ship from within the United States;
- Purchase and pay for the appropriate shipping label directly or through an authorized shipping provider;
- Use an eligible service that provides end-to-end tracking;
- Enter a valid and accurate tracking number in the order within 48 hours after payment is confirmed;
- Ship only to the address shown in the Mercado Sales transaction;
- Retain the carrier acceptance receipt until the transaction is completed;
- Comply with these guidelines and all applicable carrier requirements.
Tracking from unsupported carriers, handwritten tracking numbers, or numbers that cannot be verified through the carrier's official system may not qualify for Seller or Shipping Protection.
No Mercado Sales Prepaid Labels
Mercado Sales does not currently provide, sell, or issue prepaid shipping labels. Independent sellers are responsible for purchasing their own USPS, UPS, or FedEx shipping labels and for entering the corresponding valid tracking number in the Mercado Sales order within 48 hours after payment is confirmed.
Sellers are also responsible for selecting the correct carrier service, shipment weight, package dimensions, insurance, signature option, and any other services appropriate for the item. Shipping expenses and carrier adjustments are the seller’s responsibility unless Mercado Sales expressly states otherwise in writing.
2. Processing and Shipment Deadlines
Mercado Sales-owned products are generally processed within 1–2 business days after payment is confirmed.
Independent sellers must enter a valid USPS, UPS, or FedEx tracking number in the Mercado Sales order within 48 hours after payment is confirmed. They must give the package to the named carrier within three business days after the sale, unless a different handling period is clearly disclosed in the listing.
The 48-hour tracking deadline runs from the time payment is confirmed, including weekends and holidays. Business days for the physical shipment deadline are Monday through Friday, excluding federal and carrier-observed holidays.
Entering a tracking number does not mean the package has shipped. Marking an order as shipped before the carrier has possession of the package is prohibited. The tracking number must correspond to the actual order and show a carrier acceptance scan within the applicable handling period.
3. Determine the Billable Shipping Weight
Weigh and measure the item after it has been completely packaged. Include the box or mailer, protective wrapping, cushioning, accessories, documents, and tape.
Depending on the carrier and service, the billable weight may be the greater of:
- The package's actual weight;
- Its dimensional weight.
Dimensional weight is generally calculated as:
Measure the package at its longest, widest, and tallest exterior points. The dimensional divisor and rounding rules may vary by carrier, service, rate type, and shipping agreement. Use the rules applicable to the selected USPS, UPS, or FedEx service.
- Actual packaged weight: 5 lb
- Length: 20 inches
- Width: 12 inches
- Height: 8 inches
Dimensional weight: (20 × 12 × 8) ÷ 139 = 13.81 lb
If the selected service rounds up to the next whole pound, the billable dimensional weight would be 14 lb. Because that exceeds the actual weight, the shipment must be purchased at the 14 lb rate.
4. Select the Correct Packaging
Soft or Flexible Items
Durable, non-fragile products such as clothing may be shipped in a shipping envelope, poly mailer, or other carrier-approved soft package. Protect the contents from moisture and tearing.
Fragile, Rigid, or Valuable Items
Use a sturdy corrugated cardboard box for fragile items, electronics, collectibles, shoes, and products that could bend, break, or be crushed. Use the smallest suitable box that still allows adequate cushioning.
Do not attach a shipping label directly to collectible, branded, or valuable retail packaging. Place the retail package inside a separate shipping box unless it was specifically designed and approved for parcel shipment.
Reused Boxes
Reused boxes must remain structurally sound. Completely remove or permanently cover all previous labels, barcodes, tracking numbers, addresses, and markings that do not apply to the current shipment.
Do not remove any declaration or hazardous-material marking required for the current shipment.
Carrier-Branded Packaging
Use carrier-provided packaging only with the corresponding carrier and eligible service. For example, USPS Priority Mail packaging must not be used with USPS Ground Advantage, UPS, or FedEx services.
5. Pack the Item Securely
- Wrap fragile items individually.
- Protect sharp edges and protruding components.
- Separate multiple items with adequate cushioning.
- Fill empty space so the contents do not move during transit.
- Use extra protection for glass, ceramics, electronics, and other delicate items.
- Seal every opening with durable shipping tape.
- Do not use masking tape, gift-wrapping tape, string, or another material not intended for parcel shipping.
Before sealing the package, gently shake it. If the contents move, add more cushioning. A “Fragile” marking does not replace proper packaging or guarantee special carrier handling.
Shipping Evidence
Before shipment, photograph:
- The item's condition;
- Serial numbers or identifying marks, when applicable;
- The item inside its protective packaging;
- The sealed package;
- The shipping label attached to the package.
Keep the photographs, tracking information, and carrier acceptance receipt until the transaction is completed and any claim period has expired.
6. Media Mail and Special Servic
USPS Media Mail may be used only for qualifying content, such as eligible books, printed music, manuscripts, and certain sound or video recordings. Video games, computer drives, merchandise, and many advertising materials do not qualify.
Media Mail packages are subject to USPS inspection. The shipper is responsible for confirming eligibility and paying charges or penalties resulting from improper use. Review the official USPS Media Mail requirements before selecting this service.
Any envelope, economy, flat-rate, or other special service must be used only for eligible contents and packaging that satisfy the selected carrier’s current requirements.
7. Batteries, Liquids, and Regulated Materials
Some permitted products may still be regulated by USPS, UPS, FedEx, the U.S. Department of Transportation, or another authority. Examples include lithium batteries, perfume, aerosols, flammable liquids, pressurized containers, magnets, and certain cleaning products.
The shipper must accurately declare regulated contents and use the required service, packaging, labels, and markings. Never:
- Conceal hazardous or regulated contents;
- Ship a prohibited, leaking, damaged, defective, swollen, or recalled battery;
- Use a service that does not accept the contents;
- Remove a marking required for the current shipment;
- Reuse an unrelated hazardous-material label.
Do not automatically remove a lithium battery from a device. Mailability depends on the battery type, capacity, condition, quantity, packaging, carrier, and transportation method. For USPS shipments, consult the current USPS Publication 52. UPS and FedEx shipments must comply with the applicable carrier’s current dangerous-goods requirements.
8. Ship With the Correct Carrier and Tracking Number
The package must be given to the carrier named on the shipping label. A USPS package must be tendered to USPS, a UPS package to UPS, and a FedEx package to FedEx, except where the selected carrier service expressly provides different instructions.
- Obtain a carrier acceptance receipt or confirmation;
- Verify that the tracking number matches the package and order;
- Add the valid tracking number to the Mercado Sales order promptly;
- Monitor tracking until delivery.
The tracking number must produce verifiable shipment events through the official USPS, UPS, or FedEx tracking system.
Using the wrong carrier, entering an unrelated or recycled tracking number, or failing to obtain an acceptance scan may cause delays, cancellation, loss of payment, or denial of Seller or Shipping Protection.
9. Oversized, Heavy, and Unusual Packages
The shipper must confirm the selected carrier’s current weight, dimension, packaging, and service limits before shipment. Oversized, heavy, irregular, cylindrical, or shifting packages may be subject to dimensional-weight pricing, additional-handling charges, large-package surcharges, nonstandard fees, or rejection.
Do not enter a lower weight or smaller dimensions to reduce shipping charges. If an item cannot be shipped safely and lawfully through an eligible USPS, UPS, or FedEx service, it must not be offered for standard shipment through Mercado Sales.
10. Responsibility and Enforcement
Failure to follow these guidelines may result in:
- Carrier adjustments or additional charges;
- Deduction of applicable charges from seller proceeds;
- Delayed, returned, or refused shipments;
- Cancellation or refund of the transaction;
- Denial of Seller or Shipping Protection;
- Account restrictions;
- Other action permitted by Mercado Sales policies.
Carrier requirements control when they are more restrictive than these general guidelines.
