Moving from South Korea to the USA: 2025 Customs and Relocation Guide
Relocating from South Korea to the United States is a bold and exciting step—but it comes with its fair share of paperwork, planning, and potential pitfalls. Whether you’re a returning U.S. citizen, a student beginning a new chapter, or a family seeking new opportunities abroad, moving internationally requires more than just packing boxes. It demands a deep understanding of shipping logistics, customs documentation, and how to choose the right moving partner.
At SDC International Shipping, we’ve helped thousands of clients navigate the journey from South Korea to the U.S. with confidence. From coordinating containerized shipments out of Busan or Incheon to managing the detailed customs forms required by both countries, we guide every step of your relocation with precision and care.
In this comprehensive 2025 guide, we’ll walk you through the full process of moving from South Korea to the USA, including what to expect at customs, how to ship your household goods safely, and how SDC ensures your transition is smooth and stress-free.
Understanding the Customs Process When Moving to the USA
Every international move into the United States must pass through U.S. Customs and Border Protection (CBP). The process involves more than just declaring what you’re bringing—CBP requires specific forms, inspections, and verification of residency status.
Key Documents Required:
CBP Form 3299: This is the central form required to import household goods duty-free into the United States. It allows returning citizens or new residents to declare personal items being shipped into the country. The form asks for a full inventory of items, the origin of shipment, and the intent of use (non-commercial). Errors or omissions on Form 3299 can result in delays, additional inspections, or duties. SDC’s relocation experts complete this form on your behalf and review it with you to ensure compliance with CBP regulations.
Passport Copies: U.S. Customs requires clear, valid copies of the passports for each family member whose belongings are included in the shipment. These are used to verify identity and match names on the inventory and customs paperwork. If passports are being renewed or updated, we recommend notifying your SDC coordinator in advance so we can adjust timelines accordingly.
Visa, Green Card, or Re-Entry Permit: You must provide proof of your legal right to enter and reside in the United States. Depending on your immigration status, this could include a visa, permanent resident card (Green Card), or re-entry permit. This documentation is essential for confirming eligibility for duty-free entry of goods.
Proof of Residence in the U.S.: Customs wants to confirm that the goods being imported are for personal use in a new or returning residence. Acceptable documents include a lease agreement, utility bills, mortgage documents, or an employment contract. These documents should show a U.S. address and date of occupation that aligns with the arrival of your shipment.
Bill of Lading: This official shipping document is issued by SDC once your goods are packed and loaded. It outlines the origin, destination, container ID, and a general description of the contents. Customs officers rely on the Bill of Lading to match your shipment with your customs forms. SDC handles the generation and submission of this document.
Inventory List: Every shipment must include a detailed, itemized inventory. This list should describe each item, assign a box number or crate ID, and note estimated values. For example, rather than just listing “kitchenware,” your inventory might say: “Box #12 – 6 ceramic plates, stainless steel cutlery, electric rice cooker.” Customs uses this list to identify taxable items, ensure nothing prohibited is shipped, and confirm that values align with your CBP Form 3299.
SDC relocation specialists assist with the completion of all customs forms and thoroughly review your inventory list for clarity and completeness. We also help translate descriptions where necessary and ensure they match the terminology used by CBP and international shipping codes. Improperly filled forms or undocumented items can lead to shipment holds, additional inspections, fines, or even confiscation. With SDC’s step-by-step support, we help you avoid costly errors and expedite clearance, giving you peace of mind as you transition to your new life in the United States.
How SDC Manages International Shipping from Korea
Whether your shipment departs from the Port of Busan, Incheon International Airport, or an inland warehouse, our process is tailored to your destination and volume. Most clients opt for full container loads (FCL) or consolidated groupage containers, depending on the size of the shipment.
The SDC 6-Step Process:
1. Virtual or In-Person Survey: Our process begins with an in-depth survey—either conducted virtually via video call or on-site in your home in South Korea. This allows us to assess the exact volume, weight, and fragility of your items. We also take note of any high-value items or items that require special handling, such as antiques, artwork, or electronics. The survey is essential for creating a custom shipping plan and accurate cost estimate.
2. Packing and Crating: On packing day, our professional team arrives with international-grade packing materials that meet or exceed customs and freight standards. Fragile and high-value items are secured in custom-built wooden crates using moisture-resistant foam, padding, and shock-absorbent wraps. Our materials are ISPM-15 certified and designed to withstand the pressure and movement of ocean freight.
3. Labeling and Inventory: Every box and crate is assigned a unique label, which corresponds to a master inventory list. This list is not only critical for customs clearance but also for tracking and insurance purposes. We photograph each container, box, or crate for documentation, which adds another layer of transparency and protection for you.
4. Customs Documentation: All documents, Form 3299, valued inventory, passport copies, and proof of residence are compiled and cross-checked by our customs team before departure. We ensure that nothing is missing or misrepresented. Our specialists also communicate directly with our U.S. customs brokers to pre-clear shipments when possible, reducing the chances of inspection delays.
5. Shipment Dispatch: Once everything is packed and documents are approved, your goods are carefully loaded into the shipping container using strategic placement techniques to prevent shifting during transit. Depending on your preference and timeline, shipments are dispatched by sea or air freight. We manage all carrier coordination and provide tracking details throughout the journey.
6. Final Delivery: When your shipment arrives in the United States, we handle customs clearance at the port of entry and coordinate the final leg of delivery to your new address. Our U.S.-based teams manage last-mile logistics, including uncrating, debris removal, and setup (upon request). Throughout the entire process, you have a dedicated move coordinator keeping you updated.
SDC’s team in South Korea works closely with our U.S. operations to ensure seamless communication across time zones and languages. Whether it’s a last-minute update to your inventory or a scheduling change, we’re always ready to respond and adapt, so you’re never left wondering what comes next.
Common Restrictions and Prohibited Items
Each country has its own rules about what can and cannot be imported. U.S. Customs prohibits or restricts a range of goods from South Korea, including:
- Food products, especially perishables or homemade goods
- Plants, seeds, and soil
- Certain cosmetics or pharmaceuticals
- Firearms or weapons without declaration and permits
- Counterfeit goods or pirated media
Our team will help you review your packing list to flag any potentially restricted items and offer alternatives for handling or disposal.
How Long Does It Take to Ship from South Korea to the USA?
The average transit time for sea freight from Busan to a U.S. West Coast port is 21 to 30 days, while air freight can arrive in as little as 3 to 7 days, not including customs clearance and final delivery. Here’s a breakdown of estimated shipping durations:
| Shipping Method | Estimated Timeframe |
|---|---|
| Sea Freight (FCL) | 21–30 days |
| Sea Freight (LCL) | 28–40 days |
| Air Freight | 3–7 days |
We recommend beginning your relocation planning at least 8 weeks in advance, especially during high-volume seasons (summer and early fall).
