We Ship Worldwide!
International orders, Duties and Taxes:

International orders may be subject to Duties and Taxes by the receiving country. These Duties and Taxes are the sole responsibility of the recipient. Since the amount varies depending on the country, TreeHouse Supplies, Inc. is not able to estimate the amount prior to shipping the order. If you have questions about Duties and Taxes, you should contact the appropriate government office in your receiving country and determine the amount you will be required to pay. If you refuse to pay the duties and taxes, the shipping company will deny delivery of your order and return it to TreeHouse Supplies, Inc. If this happens we will deduct the cost of the return shipment from your refund amount. If we receive a bill for duties and taxes unpaid by you the customer, we will invoice you for those fees and you are obligated to pay.

We will not ship to freight forwarding companies. We use Fedex to deliver all of our worldwide shipments.


Window Shipping:

FedEx charges by DIM weight not actual window weight. You can click here to see how they calculate the shipment. So for example: Our 24x36 window's actual weight is 20 lbs, however, FedEx will rate the package at 57 lbs. because the box size is 38" x 8" x 26". Please email us if you have any questions prior to ordering.

Express Order Restrictions:

Express orders must be received by 2pm EST to be guaranteed to ship that day. Express orders received after that time will be sent out the following day. Some exceptions may be made but they are at the sole discretion of Tree House Supplies, Inc. If you have an emergency and need parts delivered by express service, but have missed the cut off time, contact us and we will try to accommodate you. We may charge a fee if the shipment has to be hand delivered to the commercial shipper. The fee is based on a case by case basis. Some products that require customization or special orders are not available for immediate shipping - i.e. Bridge Kits, Rustic Swings. If you are unsure, contact us for clarification.
