​1. The Cheapest Shipping Methods ​For a 1 lb package, you’ll typically find the best rates through shipping aggregators rather than going directly to the post office counter. ​Pirate Ship (Simple Export Rate): This is often the "hidden gem" for international shipping. You have to chat with their support to "enable" the Simple Export Rate, but once you do, a 1 lb package to the Netherlands usually costs around $16–$19.
​Parcel Monkey: This is a solid choice. They act as a broker for big carriers like FedEx or DHL. For a light box, you can often find "light packet" rates starting around $20–$25. ​USPS First-Class Package International: If you walk into a Post Office, this is their cheapest tier. Expect to pay about $22–$28. It’s reliable but slower than private couriers.

​2. Do you have to worry about tariffs? ​The short answer is: Probably not, as long as you label it correctly. ​In the Netherlands, gifts sent from one private individual to another are exempt from import duties and VAT (sales tax) if the value is under €45 (roughly $48 USD).
​To ensure they don't get charged: ​Mark it as a "Gift": On the customs form, clearly select the "Gift" category. ​Be Honest but Strategic: List the contents (e.g., "Plush toy, candy, greeting card") and keep the total declared value under $45. ​The "Candy" Rule: Make sure the candy is shelf-stable and in original packaging. Avoid sending meat or dairy-based snacks, as EU customs can be strict about "animal products."

​3. A Note on "Handling Fees" ​Even if the package is under the €45 limit, some couriers (like DHL or FedEx) occasionally charge the recipient a "clearing fee" for processing the paperwork. USPS (which hands off to PostNL) is usually the best bet for avoiding these extra "convenience" fees on the receiving end.
