Carriers use different transportation methods when delivering shipments, meaning shipping restrictions are highly dependent on the carrier. This is important to consider when selecting the right carrier for your shipment. 

Below you will find a brief overview of the shipping restrictions for each available carrier. For the most current information on carrier shipping restrictions, please refer to the web pages that are linked in each section. Please note that carrier-specific restrictions are in addition to Chit Chats’ Shipping Restrictions.

USPS

There are two main factors to consider when shipping via USPS:

  • U.S. vs International Shipments
  • Prohibited vs Restricted Items

As most international shipments travel by air, they are subject to certain safety regulations for air travel in addition to necessary customs clearance. For this reason, prohibited international shipments include and extend beyond the scope of prohibited U.S. shipments.

However, as some U.S. shipments may also travel by air, items prohibited internationally may only be restricted within the U.S. Typically these restrictions pertain to an item’s packaging or its quantity.

Chit Chats U.S. Tracked 

As Chit Chats U.S. Tracked is a service that partners with USPS for final delivery to your customers in the U.S., shipments must adhere to Chit Chats’ shipping restrictions for customs clearance in addition to USPS’s regulations.

See the above section for items prohibited and restricted by USPS for U.S. shipments.

Please note that there is no ground service option for this postage type, all shipments will travel by air.

UPS MI

As all UPS MI shipments are transported by air, they must be TSA-compliant. To be considered TSA-compliant, an item must not be classified as a dangerous good. Examples of dangerous goods include:

  • Items that are explosive, flammable, corrosive, or are oxidizers or compressed gases. This includes aerosols, perfumes, fragrances and household cleaning agents.
  • Large quantities of magnets, and Strong or Industrial Magnets & Magnetized materials
  • Dry Ice
  • Hazardous Batteries & electronic/products containing these batteries e.g. cellphone, laptops, tablets, smartwatches, etc.

The USPS has a great guide on which items may be considered dangerous goods.

UPS MI shipments are also transported by two postal services: UPS and USPS. Naturally, shipments must comply with both carriers’ requirements. For USPS, please see the above entry; for UPS, please see UPS's List of Prohibited Articles for Shipping.

Asendia

All Asendia shipments must be TSA-compliant. This is because this carrier transports shipments by air. To be considered TSA-compliant, an item must not be classified as a dangerous good. Examples of dangerous goods include:

  • Items that are explosive, flammable, corrosive, or are oxidizers or compressed gases. This includes aerosols, perfumes, fragrances and household cleaning agents.
  • Large quantities of magnets, and Strong or Industrial Magnets & Magnetized materials
  • Dry Ice
  • Hazardous Batteries & electronic/products containing these batteries e.g. cellphone, laptops, tablets, smartwatches, etc.

For more information, the USPS has a great guide on which items may be considered dangerous goods.

Additionally, as Asendia handles international shipments, please note:

  • Customs regulations for the destination country must be considered. Some countries may also require additional documentation such as a tax identification number. It is your responsibility to research requirements before you ship.
  • A CN22 customs form must be completed. This document is generated at the time of Asendia postage creation. 
  • Asendia designates all shipments as 'Merchandise', regardless of the customs content type indicated on the Chit Chats platform e.g. Documents, Gift, Returned goods, etc. This may impact the customs duties and taxes charged for your shipment. As a result, Asendia International Priority Tracked is not a postage option available for gifts. If you wish to send a gift to an international recipient, we recommend using one of our other international postage options.
