Shipping rates
We ship orders daily throughout Europe and to North America. Our rates are structured to remain clear, predictable and competitive — especially for heavier shipments.
Europe uses a simple flat-rate model per 30 kg. Outside Europe, pricing is calculated based on weight. EUR prices are leading.
United States and Canada
The United States and Canada have the same shipping rates.
Per-kg pricing (clear and scalable for larger orders).
| Pricing | EUR | USD* |
|---|---|---|
| Base rate | €12.00 | $14.12* |
| Additional cost | €3.50 per kg | $4.12* per kg |
Example calculations (United States and Canada):
7 kg: €12.00 + (7 × €3.50) = €36.50 (≈ $42.95*)
40 kg: €12.00 + (40 × €3.50) = €152.00 (≈ $178.86*)
Core European markets
Flat rate up to 30 kg. Each additional 30 kg is charged at the same rate again.

|---|---|---|
| Netherlands | €8.99 | €8.99 per additional 30 kg |
| Germany | €9.99 | €9.99 per additional 30 kg |
