What should we do if we want our supplier to handle customs clearance?

Within the 11 Incoterms, there is only one (DDP – Delivery Duty Paid) which allows the seller to take complete responsibility for the movement of the goods. Your supplier can therefore handle the customs clearance procedures, but it’s important to understand your supplier’s experience and capabilities as they may not be an experienced exporter / importer or may factor in additional costs to the overall sale to cover the additional resources for them when using DDP.
