Frequently Asked Questions about 321 Fulfillment

  • What is Section 321?

    We’re glad you asked! Section 321 is a type of shipment used to clear U.S. Customs and Border Patrol (CBP). Under Section 321, businesses are able to legally bypass tariffs and duties typically associated with international packages.

  • What are the benefits of Section 321?

    A whole lot of savings! With Section 321, you’ll be able to significantly decrease fulfillment and import duty costs. Say adiós to unnecessary spending and hola to more money in your bank account!

  • Who is eligible for Section 321?

    To be eligible for Section 321, your shipment must be valued at less than or equal to $800, and you can only send one shipment to one address per day. Multiple shipments are not allowed and may be subject to fine.

  • Are there any restrictions under Section 321?

    Yes. Although Section 321 is a great option for most businesses, it does not apply to goods that require inspection, goods subject to Anti-Dumping Duty (ADD) and Countervailing Duty (CVD), and goods that are regulated by Participating Government Agencies (PGAs), like the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).

  • The tariff is just temporary. What if things change?

    You can rest assured that, no matter the challenge, ShipMonk is here for you. If policies change in a way that is no longer advantageous, our merchants can still enjoy savings by splitting their inventory across our U.S. facilities.

  • This sounds like a loophole. Is it legal?

    Section 321 is fully compliant with the regulations set forth by U.S. Customs and Border Protection (CBP).

  • How can ShipMonk help merchants claim Section 321?

    It’s simple! Just let your Happiness Engineer know that you’d like to store your inventory in our Mexico location. From there, they’ll walk you through the required paperwork and what you can expect from the process.

  • Is my inventory safe in Mexico?

    Yes. Your inventory will be stored in ShipMonk’s secure warehouse in the El Bajio Industrial Park.

  • Does ShipMonk own and operate the warehouse facility in Mexico?

    Yes! Our facility is completely ShipMonk-owned, managed, and operated.
