Effective August 29, 2025:
 DDU (Delivered Duties Unpaid) shipping to the U.S. is not available. All U.S.-bound shipments must use DDP (Delivered Duties Paid), meaning duties and fees are prepaid if applicable.
If you have CUSMA eligible products you will need to submit certification for approval before you can buy DDP postage with preferential duty-free treatment. Learn more


When sending shipments internationally, additional charges such as taxes (e.g. VAT), tariffs, or other customs fees may apply. Depending on the service, these charges may either be paid up front before the shipment is sent (DDP) or by the recipient just prior to delivery (DDU, for non U.S destinations only.)


Delivered Duties Paid (DDP) Postage

Important: As of August 29, 2025, DDP is mandatory for all U.S.-bound shipments.

This means all duties, tariffs, and clearance fees must be prepaid when you purchase postage. If this information is not provided, no DDP postage option will be available at checkout.

Seller Requirements for U.S.-bound DDP

To purchase DDP postage, sellers must provide:

  • 10-digit HTS code (per item in the shipment)

  • Accurate Country of Origin (COO)

  • Manufacturer information (NOT required for Chit Chats International to the U.S.)

These details determine the applicable duties and tariffs.

Prepaid Fees with DDP

When purchasing DDP postage, the following fees are included upfront:

  • Tariffs – calculated based on the HTS code and Country of Origin.

  • Customs Processing – flat fee per shipment, covering administrative costs for informal entry into the U.S. It is a flat fee per shipment (1.35 USD flat fee).

  • Broker Line Item – $0.15 USD per line item (e.g., 1 t-shirt, 2 mugs, and 3 pins = 3 shipment items).

Note: These fees are subject to change. We’ve worked to keep them as low as possible to help offset the added cost of paying duties upfront.


Chit Chats International DDP postage (U.S. only) is ONLY subject to tariff fees.


Postage Services Supporting DDP

Currently supported services include:

  • Chit Chats U.S. Edge

  • USPS Priority Mail

  • Chit Chats U.S. Select

  • Chits International (destination to the U.S.)

Reminder: All shipments—including gifts and letters—require COO, HTS, and manufacturer info to calculate duties and fees.

Delivered Duties Unpaid (DDU) Postage

DDU is no longer supported for U.S. shipments.
Any shipment entering the U.S. without valid DDP postage will be held and returned at the border.

When DDU May Still Apply

For non-U.S. international shipments, postage options remain DDU. This means duties, taxes, and customs fees are collected from the recipient once the package arrives in their country.

With DDU services:

  • Recipients are responsible for paying fees before delivery.

  • If the recipient refuses, the sender may be contacted to resolve the fees or arrange return.


Chit Chats International Tracked (to destinations other than the U.S.) temporarily does not offer a dedicated DDP postage, but we are working hard with our partner to offer it once again. During this transition, if you provide a valid IOSS or VAT number tax reference number (for EU and UK recipients), your recipient will not be charged any customs and duty fees. We are actively working on extending this for other types of tax reference numbers. 


We strongly recommend sellers clearly communicate these responsibilities to their buyers in advance when using DDU services outside the U.S.
