Shipping freight across borders opens enormous opportunities for small businesses — access to global suppliers, new export markets, and competitive sourcing that simply isn't available domestically. But international freight also introduces layers of complexity that can trip up even experienced shippers: customs regulations, documentation requirements, duties and tariffs, carrier selection, and the challenge of managing multiple vendors across time zones and languages.
This guide cuts through the complexity. Whether you're importing goods from overseas suppliers or exporting products to customers in 150+ countries, you'll learn exactly what international freight involves, what documents you need, how costs are structured, and how partnering with a nationwide and worldwide freight broker and 3PL like MyExpressFreight can make the entire process seamless.
Why International Freight Trips Up Small Businesses
Most small business owners are comfortable shipping domestically. You call a carrier, get a rate, hand over the freight — done. International shipping works differently because every cross-border move involves at least two customs authorities, multiple carriers or agents, complex documentation, and regulatory compliance that varies by commodity and destination country.
The most common pain points include:
- Incorrect or incomplete customs documents — leading to delays, fines, or seizure of goods
- Underestimating landed cost — surprises from duties, taxes, and port fees that weren't factored into pricing
- Choosing the wrong transport mode — paying air freight rates for cargo that could move far more cheaply by ocean
- Unclear Incoterms — not knowing who is responsible for freight cost and risk at each stage of the journey
- No single point of contact — managing a separate freight forwarder, customs broker, drayage company, and final-mile carrier independently
The good news: all of these problems are solvable when you work with the right logistics partner. MyExpressFreight has been FMCSA licensed since 2009, serving shippers across all 50 US states and more than 150 countries worldwide, with end-to-end international freight management under one roof.
Ocean Freight vs. Air Freight: Choosing Your Mode
The two primary modes for international freight are ocean and air. Each has a distinct cost and speed profile, and choosing correctly is the single biggest lever you have on total shipping cost.
| Factor | Ocean Freight | Air Freight |
|---|---|---|
| Cost | Significantly lower per kg/cbm | 4–10x more expensive than ocean |
| Transit Time | 2–6 weeks (varies by lane) | 2–7 business days |
| Best Cargo | Heavy, bulky, or non-urgent goods | High-value, time-sensitive, or light goods |
| Container Options | FCL (full container) or LCL (shared) | Consolidated (LCL equivalent) or charter |
| Weight/Size Limits | Virtually unlimited | Practical limit ~150 kg per piece |
| Carbon Footprint | Lower per unit shipped | Significantly higher |
| Reliability | Vessel delays possible; improving | Very high schedule reliability |
A useful rule of thumb: if your shipment weighs more than 200 kg and is not urgently time-sensitive, ocean freight will almost always be more economical. For shipments under 100 kg, or for goods where a one-week delay costs more than the air freight premium, air is the right call.
Essential International Freight Documents
Customs authorities worldwide require specific paperwork to clear your freight. Missing or inaccurate documents are the leading cause of shipment delays. Here are the four core documents every international shipper needs to understand:
1. Commercial Invoice
The commercial invoice is the most important customs document. It must accurately state the seller's and buyer's full details, a complete description of the goods, the country of origin, quantity, unit value, total value, and the currency of the transaction. Customs uses this document to assess duties and taxes — inaccurate values are a serious compliance risk.
2. Bill of Lading (Ocean) / Air Waybill (Air)
The bill of lading (B/L) is the contract of carriage for ocean shipments. It serves as a receipt for the goods, a document of title, and evidence of the shipping contract. For air shipments, the equivalent is the air waybill (AWB), which functions similarly but is non-negotiable. Both documents must accurately reflect the commodity, weight, dimensions, and party names.
3. Packing List
The packing list details the contents of each carton or pallet: item descriptions, quantities, weights, and dimensions. Customs inspectors use it to verify that the physical cargo matches the commercial invoice. Discrepancies between the two documents trigger holds and inspections.
4. Certificate of Origin
A certificate of origin (COO) certifies the country in which the goods were manufactured or substantially transformed. Many trade agreements (such as USMCA, various US FTAs, and bilateral agreements) allow preferential duty rates when goods meet origin requirements — but only if a valid COO is presented. Some destinations require a COO even when no preferential rate applies.
Depending on your commodity and destination, you may also need import/export licenses, fumigation certificates, phytosanitary certificates, or a Shipper's Export Declaration (SED) via the Automated Export System (AES).
Customs Clearance, Duties & Tariffs
Every international shipment must clear customs at the destination country. In the United States, the authority is US Customs and Border Protection (CBP). Most countries have an equivalent agency that reviews documentation, assesses duties, and releases freight for final delivery.
How HTS Codes Work
The Harmonized Tariff Schedule (HTS) is a standardized numerical system used worldwide to classify traded goods. Your commodity's 10-digit HTS code (in the US) determines the applicable duty rate. Misclassification — intentional or accidental — is one of the most common and costly customs compliance mistakes. A licensed customs broker will ensure your goods are correctly classified.
Duties, Taxes, & Other Fees
Your landed cost — the true total cost of imported goods — includes more than just the purchase price and freight:
- Import duties — percentage of declared customs value, set by HTS code
- Value-added tax (VAT) or goods & services tax (GST) — levied by many countries at the border
- Merchandise processing fee (MPF) — US CBP administrative fee on formal entries
- Harbor maintenance fee (HMF) — assessed on ocean shipments entering US ports
- Customs broker fee — paid to the licensed broker who files your entry
- Drayage & port fees — moving the container from the port to your warehouse
Factoring these costs in before you sign a purchase order with an overseas supplier is essential to accurate margin calculations.
Incoterms: Who Pays, Who Insures, Who Risks What
Incoterms (International Commercial Terms), published by the International Chamber of Commerce, are standardized three-letter codes that define exactly where seller responsibility ends and buyer responsibility begins in any international transaction. The most widely used terms are:
- EXW (Ex Works) — seller makes goods available at their facility; buyer arranges and pays for all freight and export clearance
- FOB (Free On Board) — seller delivers goods to the origin port and loads them on the vessel; buyer assumes risk and cost from that point
- CIF (Cost, Insurance & Freight) — seller pays for ocean freight and minimum insurance to the destination port; buyer handles import clearance and final delivery
- DAP (Delivered at Place) — seller delivers to a named destination but does not pay import duties; buyer handles customs clearance
- DDP (Delivered Duty Paid) — seller handles everything including import duties and final delivery; maximum responsibility on the seller
For small businesses buying from overseas suppliers, FOB and CIF are the most common terms. Understanding which Incoterm your contract uses tells you exactly when your risk and cost responsibility begins — and prevents expensive surprises.

Managing an international shipment independently means coordinating a freight forwarder, a customs broker, a port trucking company, an ocean or air carrier, and a final-mile delivery partner — each with their own systems, invoices, and points of failure. One missed communication between any two of these parties can delay your shipment by days or weeks.
A full-service international freight broker and 3PL like MyExpressFreight consolidates all of this under a single point of contact. Here's what that looks like in practice:

Getting Started: A Step-by-Step Checklist
- Identify your commodity's HTS code — search the USITC HTS database or ask your customs broker; this determines your duty rate and compliance requirements
- Calculate your landed cost — add freight, duties, taxes, port fees, and customs broker fees to your purchase price before committing to a supplier
- Agree on Incoterms in writing — confirm which party handles export clearance, freight, insurance, and import clearance before signing the purchase order
- Prepare your commercial invoice accurately — ensure descriptions, values, and country of origin are correct and consistent with your packing list
- Obtain a certificate of origin — required by most customs authorities and necessary for preferential duty treatment under trade agreements
- Choose your transport mode — compare ocean vs. air based on shipment weight, urgency, and cost tolerance
- Partner with a freight broker and 3PL — a single logistics partner who handles origin, transport, customs, and final delivery eliminates coordination risk and typically delivers better rates
- Book early — peak shipping seasons (Q4, Chinese New Year, post-holiday) see tight ocean container availability; book 4–6 weeks in advance when possible
- Purchase cargo insurance — standard carrier liability is limited and rarely covers the full value of your goods; we can advise on appropriate coverage
- Track your shipment end-to-end — stay ahead of any delays, customs holds, or port congestion with real-time visibility tools
Frequently Asked Questions
What documents do I need to ship freight internationally?
The core documents for most international shipments are a commercial invoice, a bill of lading (ocean) or air waybill (air), a packing list, and a certificate of origin. Some shipments also require export licenses, fumigation certificates, or phytosanitary certificates depending on the commodity and destination country.
How does customs clearance work for importers?
When goods arrive at the destination port, a customs broker files an entry with the relevant customs authority (U.S. CBP for US imports). Customs reviews the commercial invoice, packing list, and certificate of origin, then assesses duties and taxes based on the HTS code and declared value. Once duties are paid and the entry is approved, the freight is released for final delivery.
What is the difference between ocean freight and air freight?
Ocean freight is significantly less expensive and handles large, heavy, or non-urgent cargo — typical transit times range from 2 to 6 weeks depending on origin and destination. Air freight is 4 to 10 times more expensive but delivers in 2 to 7 business days, making it ideal for high-value, time-sensitive, or lighter goods.
