Mattress Shipping Cost from Yokohama to Buenos Aires

Shipping from Japan to the US varies wildly, from around $20-$40 for small, light items (under 1kg) via Airmail/EMS to $100+ for heavy boxes, with costs depending heavily on weight, size (volumetric), speed (EMS is fast/pricier; Surface is slow/cheaper), and carrier (Japan Post vs. DHL/FedEx). Expect lighter items like books to cost $25-$40, while heavier personal effects could be $90-$250+.

If you need to ship to the US, you should use Yamato, DHL, UPS, FedEx, or some other private carrier. If that is not practical, refund your customers and cancel their orders. You can't control the USPS and this is not likely to get cleared up soon.

Shipping from Japan to the US takes anywhere from 1-5 days for express air freight (like DHL/FedEx) to 2-4 weeks for standard airmail, and even longer (1-3 months) for the cheapest surface mail, with ocean freight falling in the middle at 2-4 weeks to the West Coast and longer for the East Coast, heavily depending on the chosen carrier and customs clearance.
