Most dropshippers calculate their margin using the supplier’s product price and a rough shipping estimate, list the product, run ads, and find out three weeks later that the “profitable” $22 item actually lost them $1.40 per order once duty, brokerage, and a currency swing hit the invoice. That’s not a shipping problem. That’s a landed cost problem, and in 2026, with Section 301 and Section 122 both stacking on top of standard duty rates, it’s the difference between a store that survives Q4 and one that doesn’t.
This article gives you the actual landed cost formula for dropshipping, walks through a real calculation, and shows where sellers lose money without noticing.
What “landed cost” actually means (and why your supplier’s price isn’t it)
Landed cost is the total cost of getting one unit from a factory in China to your customer’s door, fully cleared through customs. It’s not the product price. It’s not the product price plus shipping cost. It’s every dollar that touches the product before it’s sellable, calculated per unit, in the currency you actually get charged in.
That includes the product price itself, international shipping or freight, customs duties (base duty rate plus Section 301 and Section 122), brokerage fees, VAT or import tax depending on destination, insurance, and any fulfillment or last-mile fee. Skip one line item and your “calculated” landed cost is wrong, sometimes by 20% or more.
The landed cost formula for dropshipping in 2026
Here’s the calculation, in order:
Landed cost per unit = Product price + Freight per unit + (Product price × duty rate, including Section 301 and Section 122) + Brokerage fee per unit + VAT or import tax (if applicable) + Insurance per unit
Walk it through with a real example: a phone accessory sourced from Shenzhen, shipped by air to a US warehouse, sold direct-to-consumer.
| Cost component | Amount | Notes |
|---|---|---|
| Product price | $3.50 | Factory invoice, per unit |
| Freight (air, consolidated) | $1.80 | Per unit, based on chargeable weight |
| Base HTS duty | $0.00 | 0% for this HS code |
| Section 301 (25%) | $0.88 | Applied to product price |
| Section 122 (10%) | $0.35 | Additional duty, stacks on Section 301 |
| Brokerage fee | $0.15 | Prorated flat fee per unit |
| Total landed cost per unit | $6.68 | Before VAT, if selling into UK/EU |
Sell that unit at $14.99 and your margin looks fine on paper. Sell it at $8.99 because a competitor undercut you, and you’re losing money before you’ve paid for the ad that brought the customer in.
Section 301, Section 122, and why de minimis doesn’t save you anymore
Through 2024, a lot of small dropshipping shipments cleared under the de minimis exemption, meaning parcels under $800 skipped formal customs duties entirely. That exemption is gone for China-origin goods. Every shipment, regardless of size, now runs through Section 301 (the China-specific tariff, ranging roughly 7.5% to 25% depending on the product’s HS code and tariff list) and Section 122 (the additional duty layered on top, currently around 10% on most categories). They stack. A product that used to clear duty-free now carries 20 to 35 points of combined duty rate.
This is also where the DDP versus DDU decision matters. Under delivered duty paid shipping, the duty and tax get calculated and paid before the parcel ships, so there’s no surprise customs bill or held package at the border. Under DDU, your customer (or you, after the fact) gets the invoice from customs directly, usually with a brokerage markup you didn’t budget for.
Brokerage, VAT, and the fees hiding in your invoice
Brokerage fees are the line item most calculators skip entirely. A customs broker charges per shipment, not per unit, so if you’re shipping small parcels one at a time, that flat fee (often $8 to $25 per entry in the US) can quietly wreck your cost per unit on low-value orders. Consolidating shipments through a fulfillment partner spreads that fee across hundreds of units instead of one.
VAT is a separate calculation if you’re selling into the UK, EU, or Australia. For orders under £135 (UK) or €150 (EU), VAT is typically collected at checkout through IOSS registration rather than at the border, which changes where that cost line sits in your formula. Get this wrong and either your customer gets hit with an unexpected import tax on delivery (refused parcels, bad reviews) or you’re absorbing VAT you never accounted for.
Currency exchange rates add one more variable. If your supplier invoices in RMB and you’re calculating margin in USD or GBP, a 2 to 3% swing in exchange rates between order date and payment date changes your actual landed cost without you touching a single supply chain decision.
DIY landed cost calculation vs. DDP fulfillment: what it actually costs
| DIY (own broker, DDU) | DDP fulfillment (EboxMan model) | |
|---|---|---|
| Brokerage fee handling | Per shipment, billed separately, often after the fact | Built into per-unit landed cost upfront |
| Section 301 + 122 | Calculated manually per HS code, easy to miscode | Pre-calculated and included in quoted price |
| Surprise customer bills | Common, hurts reviews and refund rate | None, duty is prepaid |
| Time to calculate landed cost | Hours per SKU, manual spreadsheet | Quoted with tariff included, same day to 24h |
| Best for | High-volume sellers with in-house customs expertise | Small businesses and growing stores without a customs team |
A 7-step checklist to calculate landed cost before you list a product
- Get the exact product price from your supplier’s invoice, not a quoted “around $X” figure.
- Confirm the HS code with your supplier or sourcing agent, since duty rate and Section 301 list assignment depend entirely on it.
- Calculate freight per unit based on actual chargeable weight for your shipment size, not a flat “shipping cost” guess.
- Apply Section 301 and Section 122 percentages to the product price, and add base HTS duty if it applies.
- Add your broker’s flat brokerage fee, prorated across the units in that shipment.
- Add VAT or import tax if shipping into the UK, EU, or Australia, and confirm whether it’s collected at checkout or at the border.
- Convert everything to your selling currency using current exchange rates, then set your product price with margin on top of the total, not the factory price alone.
When this formula doesn’t apply, and when a competitor’s tool is the better fit
If you’re already routing everything through CJdropshipping, Zendrop, or EPROLO and selling exclusively into the US at low order values, their built-in calculators handle a version of this automatically, and for a single-country, single-warehouse setup that’s often good enough. Zendrop’s US-warehouse inventory in particular skips a chunk of this calculation for orders fulfilled domestically. This detailed, manual landed cost formula matters most when you’re sourcing custom or branded products directly from Chinese suppliers, shipping to multiple countries with different VAT rules, or scaling past the point where a generic app calculator’s assumptions start missing your real duty rate.
Get your landed cost calculated correctly, not estimated
A landed cost formula only protects your margin if the inputs are accurate, and getting Section 301, Section 122, brokerage, and VAT right for your specific product and destination isn’t something a generic calculator does reliably. EboxMan quotes tariff-inclusive landed cost on every sourcing request, with a reply within 24 hours, so you know your real cost per unit before you set a price. Get a free sourcing quote and stop guessing at the number that decides whether you profit or lose money on every order.
