Cross-border selling usually fails on paperwork and surprise duties rather than on demand. This guide covers the decisions that determine whether international orders arrive smoothly: incoterms, customs data, carrier lanes and tax registration.
- DDP removes the doorstep-duty surprise that drives refusals
- HS codes and country of origin belong in your SKU master
- Split lanes by order value: express high, consolidation low
- IOSS keeps EU low-value orders moving cleanly
DDP vs DDU: the decision that shapes everything
Under DDU the customer pays duties and taxes on arrival, which looks cheaper until you count refused parcels, chargebacks and reviews written at a customs counter. Under DDP duties and taxes are collected at checkout and remitted for the customer, so the parcel clears cleanly.
DDP costs more per order and converts better, especially on higher-value goods. Model it against your real destination mix rather than assuming: for some low-value, low-duty markets DDU is genuinely fine.
Customs data is a product data problem
Most clearance delays trace to incomplete or inconsistent declarations. Every SKU needs an HS tariff code, a country of origin and a declared value stored in the product master, not typed in per shipment.
Once that data exists, commercial invoices, packing lists and electronic advance data can be generated automatically at label print, and destination restriction checks can stop non-compliant orders before they ship.
- HS tariff code per SKU
- Country of origin per SKU
- Accurate declared value and currency
- Restricted-category checks by destination
Choosing carriers lane by lane
Express integrators like DHL, FedEx and UPS deliver in two to five days and clear customs aggressively. Postal consolidation is dramatically cheaper on lightweight, low-value parcels but takes one to three weeks.
The right answer is usually both, split by order value with a rule: express above a threshold, consolidation below. Publishing honest delivery estimates for each option matters more than the option itself.
Tax registration and thresholds
The EU's IOSS scheme lets you collect VAT at checkout on low-value consignments and transmit the registration number in the customs data, avoiding collection at the border. The UK has its own low-value regime, and other markets have their own thresholds.
Registration obligations are country-specific and change; treat them as a finance decision informed by your destination mix, and revisit them as international volume grows.
