A buyer we advised quoted a $12,000 lighting order. After freight, duty, and port charges, the real cost was $17,300. That's a 44% gap between "what the supplier quoted" and "what the warehouse received."

This gap has a name: landed cost. Every seasoned importer calculates it. First-timers skip it. The difference is usually one rejected budget request or one angry CFO conversation.

Here's the formula. Every line item. No hand-waving.

Your FOB price is not your real cost. The gap between invoice and warehouse averages 25-48%. This guide gives you the exact formula — freight, duty, port charges, exam fees, trucking — with real 2026 rate benchmarks. One spreadsheet template replaces six months of painful surprises.

TL;DR

Your FOB price is not your real cost. The gap between invoice and warehouse averages 25-48%. This guide gives you the exact formula — freight, duty, port charges, exam fees, trucking — with real 2026 rate benchmarks. One spreadsheet template replaces six months of painful surprises.

The Landed Cost Formula

Forget what your supplier's invoice says. Here's what actually leaves your bank account:

Landed Cost = FOB + Ocean/Air Freight + Insurance + Customs Duty + Customs Bond + Port Charges + ISF Filing + Exam Fees (if flagged) + Trucking + Warehousing

This is what "per-unit cost" actually means. Everything else is fantasy accounting.

Line by Line: What Each Component Costs

1. FOB Price — The Starting Number

Free On Board. What you pay the supplier to get goods onto the vessel at the origin port. This is the number on your invoice. It is also the smallest number in this equation.

A $10,000 FOB order of 1,000 LED downlights from Zhongshan to Los Angeles. Let's trace it.

2. Ocean Freight — $1,200-2,800

Depends on volume (CBM) and container type. A 20-foot container from Shenzhen/Shanghai to LA/Long Beach runs $1,800-3,500 as of mid-2026. LCL (less than container load) for 2-5 CBM runs $200-400 per CBM.

Our 1,000 downlights at roughly 2.5 CBM: budget $600-1,000 for LCL ocean freight to US West Coast. East Coast? Add 40-60%. Europe (Rotterdam/Hamburg)? Similar to West Coast rates plus $200-400 for the Suez surcharge.

RouteLCL (per CBM)20' FCL40' FCL
China → US West Coast$200-380$1,800-3,500$2,800-5,200
China → US East Coast$280-520$3,200-5,800$4,500-7,800
China → North Europe$220-400$2,200-4,200$3,200-6,000
China → Middle East (Jebel Ali)$180-320$1,600-2,800$2,400-4,200
China → Southeast Asia$120-250$800-1,800$1,200-2,600

3. Marine Insurance — $50-150

0.3-0.5% of CIF value. On $10,800 CIF: $32-54. Most forwarders quote a minimum of $50-75. Don't skip this. One container of water-damaged LED drivers is a $12,000 lesson in why $50 matters.

4. Customs Duty — $300-2,500

Calculated on CIF value (Cost + Insurance + Freight), NOT FOB. This is where buyers routinely under-budget.

LED luminaires (HS 9405.40): 3.9% from most countries. LED drivers (HS 8504.40): 0-2.5%. On $10,800 CIF at 3.9%: $421. But here's the trap: misclassification. If Customs reclassifies your "LED luminaire" as "electrical apparatus" (HS 8543.70, 5.3%), your duty jumps to $572. And if Section 301 tariffs apply, add 25%.

Reality check: A US buyer we work with imported "decorative LED strips" at HS 9405.40 (3.9%). Customs reclassified as HS 8541.40 (LED components, 0%). That's a refund situation — but it took 14 months and $2,400 in legal fees. Classification matters before you ship, not after.

5. Customs Bond — $200-600/year

Required for any US import over $2,500. Continuous bond: $500-600/year (good if you import 3+ times annually). Single-entry bond: $50-150 per entry. Budget the annual bond if this isn't your first rodeo.

6. ISF Filing — $25-75

Importer Security Filing. Mandatory for US ocean freight. Must be filed 24 hours before vessel departure. Miss the deadline, and CBP hits you with $5,000 per violation. Your forwarder typically handles this — confirm it's in their quote.

7. Port & Destination Charges — $300-800

Terminal handling, documentation fee, chassis usage, pier pass, clean truck fee. These are fixed charges that don't scale with order size — which means they hurt more on small orders.

ChargeTypical RangeWho Bills It
Terminal Handling (THC)$150-350Forwarder / shipping line
Documentation Fee$45-85Forwarder
Chassis Usage (per day)$25-45Trucker / chassis pool
Pier Pass / Clean Truck$40-80Port authority
Customs Entry Fee$75-150Customs broker
Delivery Order$45-65Shipping line

8. Customs Exam (if flagged) — $300-1,200

Roughly 3-5% of containers get flagged for exam. X-ray exam: $300-500. Physical/tailgate exam: $600-1,200. Plus 3-7 days of delay. Plus chassis detention at $25-45/day while the container sits. Budget $500 as a contingency line item — if you don't get flagged, that's margin. If you do, you're covered.

9. Trucking / Last Mile — $350-800

Port-to-warehouse within 200 miles: $350-600 for LTL. Beyond 200 miles: $500-1,200. FTL (full truckload) for full containers within 200 miles: $600-900. Get quotes from 3+ drayage carriers — pricing varies wildly by lane and driver availability.

10. Warehousing — $100-400

If your goods clear customs but your warehouse isn't ready: storage at a CFS (Container Freight Station) runs $20-40/pallet/month. Plus in/out fees of $15-25 per pallet. Two weeks of storage for 4 pallets: $160-320.

The Full Calculation: A Real Example

Line ItemAmount
FOB (1,000 LED downlights, $10/unit)$10,000.00
Ocean Freight (LCL, 2.5 CBM to LA)$800.00
Marine Insurance (0.4%)$43.20
Customs Duty (3.9% on $10,843 CIF)$422.88
Customs Bond (single entry)$100.00
ISF Filing$45.00
Port Charges (THC + doc + pier pass)$420.00
Customs Entry Fee$100.00
Exam Contingency (budgeted, may not trigger)$500.00
Trucking (180 miles, LTL)$550.00
Warehousing (in/out, 1 week)$180.00
Total Landed Cost$13,161.08
Per-unit Landed Cost$13.16

That's a 31.6% premium over the $10,000 FOB invoice. And if customs flags the container for exam, add $500-700. If Section 301 tariffs apply, add another $2,500. Suddenly your "$10/unit lights" cost $16.41 each.

The per-unit reality: When your sales team quotes a customer based on "$10/unit landed cost," they're building margin on a number that's off by $3.16 per unit — $3,161 on a 1,000-unit order. That's not a procurement error. That's a profitability error.

When Air Freight Beats Ocean (Yes, Really)

Ocean freight's per-kg rate is 5-8× cheaper than air. But that's not the whole story. Air eliminates port charges, chassis fees, exam delays, and the 30-45 day cash-flow float while your money sits in a container somewhere in the Pacific.

FactorOcean (LCL)Air Freight
Freight cost (2.5 CBM / 420 kg)$800$2,100 (@ $5/kg)
Port/doc/bond/ISF$665$45 (doc only)
Transit time30-40 days5-7 days
Cash-flow cost (30 days @ 8% annual)~$72~$12
Subtotal (freight + fees)$1,537$2,157

Air is $620 more. But if getting products to market 25 days faster generates $800 in revenue or avoids a stockout penalty, air wins. Run both numbers every time.

Common Questions from Buyers

How do I find the right HS code for my product?
Start with your supplier. Ask: "What HS code do you use when exporting this product?" Most experienced exporters know their codes. Then verify independently using your country's tariff lookup tool (USITC HTS Search for US, TARIC for EU). Cross-check the duty rate matches. If the supplier's code carries a 25% tariff and you find an alternative at 3.9% with legitimate grounds, use the lower rate — but have a customs broker review the classification before you file. Wrong classification discovered in an audit means back duties plus penalties.
What's the difference between a customs broker and a freight forwarder?
A freight forwarder moves your goods. A customs broker clears them through customs. Many forwarders offer in-house brokerage, but they're functionally separate roles. The forwarder books the vessel/plane, arranges pickup, and handles documentation with the carrier. The broker files the entry with customs, calculates and pays duties, and handles any exam requests. For your first order, use a forwarder who offers integrated brokerage — fewer handoffs means fewer dropped balls. For regular importers, a dedicated customs broker often saves money through better classification and duty optimization.
My supplier offered DDP terms. Should I take it?
DDP (Delivered Duty Paid) means the supplier handles everything — freight, duty, customs clearance, delivery to your door. It sounds great. The catch: you lose visibility into every cost component, and the supplier builds a 15-25% margin into each line. You're also legally the importer of record on DDP shipments to the US — meaning if the supplier under-declares value to save duty, you're on the hook for the penalty. DDP makes sense for samples and orders under $2,000. For anything larger, run your own landed cost and compare against the DDP quote. You'll usually find 10-20% savings running it yourself.
How often should I recalculate my landed cost?
Every order. Freight rates move weekly. The Shanghai Containerized Freight Index (SCFI) swung from $1,200 to $5,800 and back to $2,100 in 18 months (2024-2026). Duty rates change with trade policy — sometimes overnight. Currency moves daily. A landed cost calculated in January can be off by 15-20% in July just from freight rate shifts. Build a spreadsheet template once, plug in fresh numbers each order, and you'll never be surprised by the final invoice.
