Overview of International Shipping
International shipping is the process of moving goods from a manufacturer in one country to a buyer in another. For most hardware and consumer product founders, this means shipping from factories in China, Vietnam, India, or other manufacturing hubs to destinations in the United States, Europe, or other markets.
The logistics chain typically involves multiple parties: your supplier, a freight forwarder, an ocean or air carrier, a customs broker, a drayage company (for trucking from port), and potentially a third-party logistics (3PL) warehouse. Each handoff introduces cost, time, and risk.
Shipping costs typically represent 5-15% of your total landed cost for ocean freight, or 15-35% for air freight. Getting this right is critical to your margins. A $5 product that costs $3 to ship by air has very different economics than one that costs $0.50 to ship by ocean.
Key Insight
Your shipping strategy should be decided before you finalize your product pricing. Many first-time importers underestimate logistics costs by 30-50%, which destroys their margins. Always get freight quotes before committing to retail prices.
Shipping Methods Compared
There are five primary methods for shipping goods internationally. The right choice depends on your shipment size, urgency, budget, and product type. Here is a detailed comparison of each.
Ocean Freight — Full Container Load (FCL)
You rent an entire shipping container (20ft or 40ft) for your goods exclusively. A 20ft container holds roughly 28 cubic meters and up to 21,000 kg. A 40ft container holds about 58 cubic meters. FCL is the most cost-effective method for large shipments.
Cost
$2,000–$5,000/container
Transit
14–35 days
Best For
Large orders, 10+ CBM
Per-Unit
Lowest cost option
Ocean Freight — Less Than Container Load (LCL)
Your goods share container space with other shippers. You pay per cubic meter (CBM). LCL is ideal when your shipment is too large for air freight but too small to fill a container. The consolidation and deconsolidation process adds 5-7 days to transit time compared to FCL.
Cost
$50–$100/CBM
Transit
20–40 days
Best For
1–10 CBM shipments
Per-Unit
Low, but higher than FCL
Air Freight
Goods are shipped on commercial or cargo airlines. Air freight is 4-5x more expensive than ocean but 5-10x faster. It makes sense for high-value, low-weight products, urgent restocks, or initial sample shipments. Most air freight is priced by whichever is greater: actual weight or volumetric weight (length x width x height / 6000 in cm).
Cost
$4–$8/kg
Transit
3–5 days
Best For
Urgent, high-value goods
Per-Unit
High
Express Courier (DHL, FedEx, UPS)
Door-to-door service with tracking and customs handled by the courier. Express is the simplest option but the most expensive. It is ideal for samples, prototypes, and very small shipments under 100 kg. Many Chinese suppliers have discounted DHL/FedEx accounts and can offer better rates than you would get directly.
Cost
$20–$50/kg
Transit
2–5 days
Best For
Samples, under 100 kg

Rail Freight (China–Europe)
Rail freight via the China-Europe Railway Express has become a viable middle ground between ocean and air. Trains travel from Chinese manufacturing hubs through Central Asia to European destinations. Transit times are roughly half of ocean freight at about 60-70% of air freight cost. This option is primarily relevant for Europe-bound shipments.
Cost
$3,000–$8,000/container

Understanding Incoterms
Incoterms (International Commercial Terms) are standardized trade terms published by the International Chamber of Commerce. They define who pays for what, who bears the risk at each stage, and where responsibility transfers from seller to buyer. Getting this wrong can mean unexpected costs of thousands of dollars.
EXW (Ex Works)
Buyer bears all cost and risk from factory gate
The supplier makes the goods available at their premises. You are responsible for everything: loading, inland transport to port, export clearance, ocean/air freight, import clearance, and delivery. This gives you maximum control but requires significant logistics knowledge.
When to use: You have an experienced freight forwarder and want full control over shipping costs. Not recommended for beginners.
FOB (Free on Board)
Risk transfers when goods are loaded onto the vessel
The most common Incoterm for importing from Asia. The supplier handles inland transport, export customs, and loading onto the ship. You take over once the goods are on board. You pay for ocean freight, marine insurance, import customs, and delivery. FOB pricing from suppliers is the industry standard for comparing quotes.
When to use: Most import situations. This is the recommended default for founders importing from Asia.
CIF (Cost, Insurance, and Freight)
Supplier pays for freight and insurance to destination port
The supplier arranges and pays for ocean freight and minimum insurance to the destination port. Risk still transfers at the origin port. This seems simpler, but suppliers often mark up freight costs by 15-30%. You also have less control over carrier selection, routing, and insurance coverage.
When to use: When you want simplicity and do not mind paying a premium. Compare the CIF price against FOB + your own freight quote to see if it makes sense.
DDP (Delivered Duty Paid)
Supplier handles everything to your door
The supplier is responsible for all costs and risk until the goods arrive at your specified destination, including import duties and taxes. This is the most hands-off option for you, but also the most expensive. Suppliers typically add a substantial margin for taking on this responsibility. It also means you cannot claim import duty drawbacks or reclaim VAT.
When to use: Small shipments where convenience outweighs cost, or when you have zero logistics experience and need a simple starting point.
Pro Tip
Always get quotes on FOB terms, even if you plan to use CIF or DDP. This gives you a baseline to compare against and negotiate. Many experienced importers start with DDP for their first order to learn the process, then switch to FOB once they have a reliable freight forwarder.
Working with Freight Forwarders
A freight forwarder is your logistics quarterback. They coordinate the movement of your goods from the supplier's factory to your warehouse, handling booking cargo space, preparing documentation, arranging customs clearance, and managing the handoffs between carriers. For most importers, a good freight forwarder is the single most important logistics partner you will have.
Freight forwarders do not own ships or planes. They are intermediaries who negotiate rates with carriers on behalf of their clients. Because they consolidate volume from many shippers, they typically get better rates than you could negotiate directly. Their fee is usually built into the freight rate or charged as a flat service fee.
Freight Forwarder Cost Structure
How to Choose a Freight Forwarder
- Get quotes from at least 3 forwarders for the same shipment
- Ask about their experience with your origin country and product type
- Check if they have offices or agents at both origin and destination
- Ask for references from other importers in your product category
- Verify they are licensed (FMC license for US, FIATA for international)
- Test their communication responsiveness before committing
Customs Clearance
Customs clearance is the process of getting your imported goods approved by the destination country's customs authority. This involves submitting documentation, paying applicable duties and taxes, and passing any required inspections. In the US, this is handled by US Customs and Border Protection (CBP).
Most importers use a licensed customs broker (often your freight forwarder offers this service) to handle clearance. The broker prepares and submits the entry documents, classifies your goods under the correct HS code, calculates duties owed, and pays them on your behalf.

HS Codes and Duty Calculation
The Harmonized System (HS) code is a 6-10 digit number that classifies your product for customs purposes. The code determines the duty rate you pay. Getting the HS code wrong can mean overpaying duties, underpaying (which triggers penalties and audits), or having your shipment held at customs. US duty rates range from 0% to 25%+ depending on the product and country of origin. Use the USITC Harmonized Tariff Schedule or our HS Lookup tool to find the correct code.
Full Cost Breakdown
Your total landed cost includes far more than just the freight charge. Here is a comprehensive breakdown of every cost category you should budget for when importing goods. These figures represent typical ranges for a standard ocean freight shipment from China to the US.
Landed Cost Components
The quoted unit price from your supplier
Rates fluctuate seasonally; peak season (Aug–Oct) can be 2x higher
Minimum charge usually 1 CBM
All-risk coverage recommended; never skip insurance
Flat fee per entry; may be higher for complex shipments
Based on HS code and country of origin; check for Section 301 tariffs
US CBP fee on all imports
US fee on ocean imports only
Trucking from port; varies by distance
3PL receiving fees of $25–$50/shipment additional
Must be filed 24+ hours before vessel departure
Quick Formula
Landed cost per unit = FOB price + (total freight / units) + (duty rate x FOB price) + (insurance / units) + (brokerage / units) + (drayage / units) + (warehouse receiving / units). For a rough estimate, add 30-45% to your FOB price for ocean freight to the US, or 50-80% for air freight.
Shipping Timelines
Understanding realistic shipping timelines is essential for inventory planning, product launches, and cash flow management. The times below represent port-to-port transit plus typical customs clearance and delivery. Add 3-7 days for factory to port at origin and warehouse delivery at destination.
| Route | Ocean (FCL) | Ocean (LCL) | Air | Express |
|---|---|---|---|---|
| China to US West Coast | 14–21 days | 20–28 days | 3–5 days | 2–4 days |
| China to US East Coast | 25–35 days | 30–40 days | 4–6 days | 3–5 days |
| China to Europe (ocean) | 28–35 days | 33–42 days | 4–7 days | 3–5 days |
| China to Europe (rail) | 14–18 days | N/A | — | — |
| Vietnam to US West Coast | 18–25 days | 24–32 days | 4–6 days | 3–5 days |
| India to US East Coast | 25–35 days | 30–40 days | 4–7 days | 3–6 days |
| Mexico to US (truck) | 3–7 days | — | 1–2 days | 1–3 days |
Plan for Delays
Always add a 25-50% buffer to quoted transit times. Port congestion, weather, customs inspections, and holiday seasons (especially Chinese New Year in January/February) can add 1-3 weeks to ocean shipments. Peak shipping season runs from August through October, when holiday inventory is being moved. Book early and expect higher rates during this period.
Common Problems & Solutions
Even experienced importers encounter shipping problems. The key is knowing what can go wrong, having contingency plans, and understanding your recourse options. Here are the most common issues and how to handle them.
Shipping Delays
Port congestion, weather events, carrier schedule changes, and customs holds can delay your shipment by days to weeks. During COVID, some ocean shipments were delayed by 2-4 weeks.
Solution
Build buffer time into your inventory plan. Maintain 4-6 weeks of safety stock. Use shipment tracking tools and set up alerts. Have a backup air freight plan for critical inventory.
Cargo Damage
Goods can be damaged during loading, transit, or unloading. Water damage from leaking containers, crush damage from improper stacking, and temperature damage for sensitive goods are all common.
Solution
Always purchase marine insurance (0.3-0.5% of cargo value). Require proper export packaging from your supplier. Use moisture absorbers in containers. Document everything with photos at receiving.
Demurrage & Detention Charges
Demurrage is charged when your container sits at the port terminal beyond the free days (typically 3-5 days). Detention is charged when you keep the container beyond the allowed time after pickup. Rates are $100-$300 per day per container and escalate over time.
Solution
Have your customs broker and drayage company lined up before the ship arrives. Pre-clear customs when possible. Confirm warehouse receiving appointments in advance. Monitor vessel tracking for ETA changes.
Customs Holds & Inspections
CBP can hold your shipment for document review, physical inspection, or examination. Inspections typically cost $300-$1,000 for unloading, re-loading, and storage fees, and can delay your shipment by 3-10 business days.
Solution
Ensure all documentation is accurate and complete before the shipment arrives. Use correct HS codes. File ISF on time. Maintain a clean import history. Respond immediately to any CBP requests.
Lost or Missing Cargo
While rare, containers can be lost at sea, misrouted, or items can go missing during LCL consolidation. About 1,000-3,000 containers are lost at sea annually.
Solution
Always insure your cargo for full replacement value plus freight costs. Keep copies of all shipping documents. Use container tracking. For high-value shipments, consider splitting across multiple containers.
Incorrect HS Code Classification
Using the wrong HS code can result in overpaying duties, underpaying (triggering audits and penalties), or having your product flagged for additional regulatory requirements.
Solution
Get a binding ruling from CBP before your first shipment. Consult with your customs broker on classification. Keep records of how your HS code was determined. Review classification annually as trade policy changes.
Tips for First-Time Importers
Your first import shipment is a learning experience. Here are the most important things to get right from the start.
- 1
Start with a small order via express or air freight
Your first order should be a test run. Ship a small quantity by express courier to verify product quality, packaging integrity, and your customs clearance process before committing to a full container.
- 2
Get your customs bond before you need it
US imports over $2,500 require a customs bond. A single-entry bond costs $50-$100 per shipment. A continuous bond costs $300-$500 per year and covers unlimited entries. If you plan to import regularly, get a continuous bond.
- 3
Find a freight forwarder before placing your production order
You need freight quotes to calculate your true landed cost. A good forwarder will also advise on packaging requirements, documentation, and help you avoid common mistakes.
- 4
Never skip marine insurance
At 0.3-0.5% of cargo value, insurance is one of the cheapest costs in your supply chain. A single damaged shipment without insurance can cost more than years of premiums. Insure for CIF value plus 10%.
- 5
Understand your HS code and duty rate before pricing your product
Duties can range from 0% to over 25%. Section 301 tariffs on Chinese goods add an additional 7.5-25% on many product categories. These costs must be factored into your retail price.
- 6
Plan for total transit time, not just sailing time
Total time from factory to warehouse includes production, factory to port, port waiting, ocean transit, customs clearance, drayage, and warehouse receiving. A realistic timeline from China to a US warehouse is 6-10 weeks from production completion.
- 7
Keep impeccable records
Save every invoice, packing list, bill of lading, and customs entry for at least 5 years. CBP can audit your imports and request documentation at any time. Organized records also help when filing insurance claims or disputing charges.
- 8
Build relationships, not just transactions
Your freight forwarder, customs broker, and drayage company are long-term partners. A good relationship means better rates over time, priority handling during peak seasons, and someone who will go the extra mile when problems arise.
