Yes, shipping is part of customs value in most ecommerce imports
Under the WTO Customs Valuation Agreement, the transaction value of imported goods is the price actually paid or payable plus certain additions. Additions include the cost of transport and insurance up to the place of importation. For most ecommerce imports arriving by air or sea, that place is the destination country border, port, or airport. So the answer is yes: international freight is included.
- Transaction value is the default valuation method for ecommerce shipments.
- Cost of transport to the border (or to the place of importation) is an addition.
- Insurance taken with the freight shipment is also an addition.
- Handling fees tied to the freight leg follow the same rule as the freight itself.
When the answer is different
The simple "yes" depends on the Incoterm and on who pays for freight. EXW means the buyer pays freight from the seller's warehouse, so the freight amount appears under the buyer's costs and still ends up in customs value. FOB, CFR, and CIF shift who is named on the freight invoice, but the addition to customs value is still computed at the destination border. DDP asks the seller to deliver goods duty paid to the buyer's address; the freight, duty, and tax are all paid by the seller, and the freight portion still belongs in customs value.
- EXW: buyer pays freight; freight amount still added to customs value.
- FOB / CFR / CIF: freight up to the border is included; domestic freight inside the destination is not.
- DDP: seller pays freight, duty, and tax; freight portion still added to customs value.
- DAP: seller pays freight but not duty; freight portion still added to customs value.
What is added versus what is not added
The additions to customs value are tightly defined. For ecommerce sellers, the practical question is which line items belong in the customs value and which do not.
- Added: international freight cost, marine or air cargo insurance, handling tied to freight.
- Added: packing cost for export (when charged separately to the buyer).
- Not added: costs inside the destination country after the goods clear customs.
- Not added: post-importation installation, assembly, or technical service.
- Not added: discounts or rebates that meet the deduction conditions under national rules.
How to record shipping on the commercial invoice
The commercial invoice is the source document for customs value. Carriers and customs brokers will read the invoice line by line to confirm what is and is not added. Write the freight as a separate line under the goods, name the Incoterm in the invoice terms box, and keep the freight amount in the same currency as the goods.
- Add a "Total goods value" line, a "International freight" line, and a "Insurance" line.
- Name the Incoterm (FOB, CIF, DDP, etc.) in the invoice terms box.
- Keep freight currency consistent with goods currency to avoid extra conversion noise.
- If the seller is paying freight (CIF, DDP), the freight still appears on the invoice.

A worked ecommerce example
A Shopify seller ships a $2,000 wholesale order of cotton tote bags from Shenzhen to Los Angeles. The seller books freight at $380 and pays $40 of cargo insurance. The buyer uses CIF terms. The customs value is $2,420 ($2,000 goods + $380 freight + $40 insurance). If the seller instead quotes FOB and the buyer pays freight separately to the same freight forwarder, the customs value is still $2,420 — only the freight invoice changes hands.
Why this matters for ecommerce duty estimates
If freight is excluded from the duty base, the duty estimate is too low. Most ecommerce sellers who quote DDP without including freight in the customs value calc will undercharge the buyer or absorb the gap themselves. Most sellers who quote DDP and forget to add insurance will underreport the assessed base and risk a post-clearance reassessment by customs.
- Always include international freight in the customs value base for duty estimates.
- Always include cargo insurance in the customs value base for duty estimates.
- Use the Import Duty Calculator after you confirm the customs value inputs.
- For destinations with de minimis thresholds, customs value still matters even when duty is waived.
Common mistakes
These mistakes are common in DDP and FOB scenarios for first-time ecommerce importers.
- Forgetting to add freight when the buyer pays the carrier directly.
- Adding only the freight cost but not the cargo insurance.
- Adding freight to the place of destination instead of the place of importation.
- Using the wrong currency conversion date for freight.
- Bundling handling fees that should be split between pre-shipment and freight.
