Why Incoterms are a margin lever, not just a logistics clause
In B2B contracts between suppliers and customers — especially when goods cross borders — the delivery clause defines who pays for transport, who arranges insurance, who handles customs clearance and at what point risk transfers from one party to the other. Incoterms® 2020, published by the International Chamber of Commerce (ICC), are the de facto standard for codifying these rules uniformly.
For a Swiss SME importing components from Germany, exporting machinery to Italy or selling online to customers across Europe, choosing the wrong Incoterm can turn an apparently profitable transaction into a loss: unexpected duties, input VAT not deducted, bonded warehouse charges or contractual penalties for delivery delays.
This guide explains how to select the Incoterm best suited to your commercial flow, how to estimate "all-in" logistics costs and how to reflect them correctly in accounting, invoicing and contribution margin calculation.
What Incoterms 2020 cover — and what they do not
Before negotiating a contract, it is essential to distinguish what Incoterms cover from what falls outside their scope:
What they include
- Seller and buyer obligations for delivery, transport and document handover
- Point of transfer of risk (loss or damage to goods)
- Allocation of main transport, insurance and export/import customs costs
- Mode of delivery (sea, air, road, multimodal)
What they do not regulate
- Transfer of ownership of goods (remains subject to the sales contract)
- Price, payment terms and warranties
- Liability for defects or product conformity
- Disputes and jurisdiction (unless additional clauses apply)
- Domestic tax obligations beyond what is required for customs clearance
In Switzerland, Incoterms apply as an international contractual standard. However, their interaction with the Code of Obligations (CO), customs legislation, the Customs Ordinance and the Federal VAT Act (VAT Act) requires careful attention: DDP ("Delivered Duty Paid") to a Swiss customer, for example, requires the foreign seller to handle importation and input VAT, with implications for the final price and tax documentation.
Most relevant Incoterms for Swiss SMEs
There is no universally "best" Incoterm: the choice depends on who has logistics expertise, transaction volumes and contractual bargaining power. Here is a comparison oriented to typical SME flows:
| Incoterm | Main transport | Insurance | Import customs | Ideal for |
|---|---|---|---|---|
| EXW | Buyer | Optional (buyer) | Buyer | Spot purchases with consolidated in-house logistics |
| FCA | Buyer | Optional (buyer) | Buyer | EU–Switzerland import/export, delivery to carrier |
| CPT / CIP | Seller | CIP: seller (minimum) | Buyer | B2B sales with transport included but customs clearance at customer's expense |
| DAP | Seller | Optional (seller) | Buyer | "Customer's door" delivery without import customs handling |
| DDP | Seller | Optional (seller) | Seller | Turnkey offer — maximum risk for the seller |
For imports into Switzerland, EXW and FCA are common when the Swiss principal has a trusted freight forwarder and wants to control costs and timelines directly. For exports, DAP and DDP are often requested by foreign customers who prefer a predictable final price — but the Swiss seller must accurately calculate duties, import VAT in the destination country and any administrative charges.
Operational allocation: shipping, insurance and customs
Every logistics cost item affects gross margin. Here is how to map it according to the Incoterm chosen:
Shipping costs
Transport breaks down into pre-carriage (from the seller's warehouse to the point of departure), main carriage (international leg) and on-carriage (from the border to the recipient). With EXW and FCA, all three segments are borne by the Swiss buyer. With CPT, CIP, DAP and DDP, the seller covers at least the main carriage — and with DAP/DDP also the on-carriage.
Operational tip: always request a "door-to-door" quote from the carrier and compare it with the allocation provided by the Incoterm. The apparent savings of EXW are often wiped out by fragmented pickup costs, border warehousing or fuel surcharges.
Transport insurance
Only CIP requires the seller to provide insurance with minimum coverage (Institute Cargo Clauses Clause A, unless otherwise agreed). Under other Incoterms insurance is optional: whoever bears the risk on the uninsured leg should arrange it independently.
For high value-added goods — electronics, precision components, pharmaceutical products — lack of insurance can wipe out an entire margin on a single damaged shipment. Include the insurance premium in the standard product cost or charge it as a separate invoice line, in line with commercial policy.
Customs, duties and import VAT
Switzerland is not part of the EU customs union. Every import from third countries (including the EU) requires a customs declaration. Duties depend on the country of origin and the TARES tariff number; import VAT (8.1% on the taxable value, unless reduced or special rates apply) is deductible as input tax for VAT-registered businesses entitled to do so, if correctly accounted for.
With DDP, the foreign seller delivering to Switzerland must register or operate through a fiscal/customs representative, pay import VAT and handle documentation. For a Swiss company selling abroad under DDP, pricing must include duties in the destination country, local VAT, customs broker fees and a buffer for tariff variations — otherwise the margin silently shrinks.
Swiss specifics: border, VAT and trade agreements
The Swiss federal context adds variables that an Incoterm alone cannot resolve. The Federal Office for Customs and Border Security (FOCBS) requires a valid UID/VAT number for B2B operations; shipments between Switzerland and Liechtenstein follow specific rules; free trade agreements (EU, EFTA, United Kingdom and dozens of third countries) may eliminate or reduce duties, but do not remove the obligation to declare or the need for certificates of origin.
For regular imports, consider accreditation as an authorised consignee (home clearance), which allows declarations to be filed at your own premises and reduces clearance times.
For exports to the EU, verify whether the customer is VAT-registered in the destination country: with DAP at the border, import VAT in the destination country is handled by the buyer, but documentation (commercial invoice, packing list, certificate of origin or REX declaration where applicable) must be impeccable to avoid customs holds.
Also watch out for the so-called "Incoterm plus": many contracts add clauses on who bears inspection, sampling, special packaging or storage costs. These charges are not covered by standard Incoterms and must be negotiated explicitly, ideally with an annex listing cost items and respective responsible parties.
Accounting and impact on margins
The choice of Incoterm directly influences how costs are recorded in accounting and how contribution margin is calculated per product or per customer:
Purchasing side (import)
- Goods price + transport + insurance + duties = cost of purchase (inventory valuation)
- Import VAT recorded as input VAT credit (account 1170), not as a cost
- Forwarder customs clearance fees: period expense or included in cost of purchase, depending on materiality
- With EXW, verify that all ancillary costs are allocated to the line item for a correct margin
Sales side (export)
- Shipping expenses included in the price (CPT, DAP, DDP) reduce gross margin if not recovered
- With DDP abroad, duties and VAT paid on the customer's behalf may require separate re-invoicing
- Exports abroad are generally exempt from Swiss VAT (Art. 23 VAT Act), but proof of export must be retained
- Monitor net margin by Incoterm: a DDP customer may only be profitable above a certain volume threshold
In Accountex, set up cost centres or analytical categories for "import logistics", "customs" and "export shipments". By linking every supplier invoice and expense report to the relevant order or customer, you obtain a realistic "landed cost" margin — essential for deciding whether to maintain a customer-friendly Incoterm or renegotiate terms.
Integrating logistics costs into B2B pricing
Three practical approaches to prevent shipping and customs from eroding margin:
All-in price with buffer
Include transport, insurance and estimated customs in the unit price, with a safety coefficient (3–8% depending on the destination country). Suitable for DAP/DDP and customers who want a fixed price.
Goods price + separate logistics line
The invoice separates the value of goods from transport and customs clearance charges. High transparency, useful with FCA or CPT. Makes it easier to verify margin on the product component alone.
Zone-based price list with default Incoterm
Define the standard Incoterm and logistics surcharge per geographic area. Example: "DAP Germany — list price + CHF 45/package"; "FCA Zurich warehouse — net list price". Reduces quoting errors.
Contractual clauses: what to specify beyond the Incoterm
An Incoterm alone is not enough. Every B2B contract with an international component should specify at least:
| Element | Sample wording |
|---|---|
| Incoterm and place | "DAP — Via Industria 12, 6900 Lugano, Switzerland (Incoterms® 2020)" |
| Reference edition | Always "Incoterms® 2020" — avoids ambiguity with previous editions |
| Tariff number | Agreed HS code for shared customs estimates |
| Insurance | "Minimum ICC(A) coverage at 110% of CIP value" where applicable |
| Documents | Commercial invoice, packing list, certificate of origin — responsibilities and timelines |
| Customs delays | Force majeure and allocation of border warehousing costs |
Operational checklist for management and the administrative office
- ✓Verify that the Incoterm indicated on the order, invoice and transport documents is consistent
- ✓Calculate full landed cost for every foreign supplier, not just the EXW price
- ✓Check deductibility of import VAT as input tax and correct posting to the input VAT account
- ✓For DDP exports, confirm fiscal registration requirements in the destination country
- ✓Document transfer of risk with the date and place specified by the chosen Incoterm
- ✓Review margins by Incoterm quarterly and realign price lists or terms if necessary
- ✓Retain invoices, customs declarations and proof of export for ten years (CO and VAT Act compliance)
Conclusion: aligning logistics, contract and accounting
Incoterms translate into standard language who pays for what along the international path of goods. For a Swiss SME, the right choice is not the one that "sounds good" in negotiation, but the one that reflects real logistics capabilities, verifiable costs and the company's risk tolerance.
By integrating the delivery clause into cost of purchase calculation, sales pricing and analytical accounting, you turn a legal clause into a margin control tool. Review terms at least once a year — or with every new market — and ensure that orders, invoices and customs procedures tell the same story.
