New Customs Descriptions

From the USPS:

“New Requirement: Detailed Content Descriptions for All International Packages”

If you're sending packages from the U.S. to any other country, you must now put more detailed item descriptions on your customs forms.

If you don't follow customs forms requirements, the customs officials in the receiving country may reject, return, or potentially even destroy your package.

Note: If you're mailing First-Class Mail International® service envelopes containing only documents that don't require customs forms, these new rules don't apply to you.

These rules apply to all international packages, here's what you need to know:

All outbound international packages, including small personal gifts, ecommerce orders, and military and diplomatic mail (APO/DPO/FPO) must follow these rules.

Every item in your package needs an appropriately detailed description on the customs form.

Each description must be specific: Detailed descriptions should make it clear what the item is, what it's made of, and what its purpose is. For example, instead of a general category like "electronics," you must be specific about the type of electronics, like "laptop computer," "mobile phone," or "television."

Why do item descriptions need more detail?

Customs authorities worldwide require HS Codes to screen incoming goods. By writing an acceptable item description on your customs form, you help to:

Streamline customs processing

Prevent delays

Improve the efficiency of cross-border ecommerce

Meet safety and security requirements

^ Don't forget many National Postal Services across the World have stopped mailing packages to the United States (only letters) because of the US' removing of the Customs Fees the (de Minimis) for items under $800 from every Country  starting today. ^
