What is a Harmonization Number?

Learn about international customs Harmonization #'s, also known as Harmonized System (HS) or Harmonized Tariff Schedule (HTS) code

Updated over 4 months ago
  • Harmonization Numbers: A Harmonization Number is a specific designation that the international mailing system assigns to products, so they can keep records of the types of items being imported into foreign countries.

Why do I need a Harmonization Number?

  • Some Countries Require Harmonization Numbers: Some foreign countries' customs departments require Harmonization Numbers to determine the customs duties and import taxes that recipients need to pay when their shipment gets imported into their specific country.

    • Depending on the country you're shipping to, adding a Harmonization # when you fill out your customs form is optional.

  • South American Countries: Certain countries in South America also require Harmonization Numbers, such as Brazil.

  • Best Practice is to Include a Harmonization Number: Since more countries are beginning to require it, the best practice for all international shipments is to enter your Harmonization # when filling out the customs form, if possible.

U.S. military addresses also require Harmonization Numbers

  • Harmonization Numbers for Military Addresses: On top of foreign destinations, shipments to military APO, FPO, and DPO addresses require harmonization codes.

    • You'll need to include the harmonization number for your item(s), no matter where the military base you're shipping to is located.

How do I find my Harmonization Number?

  • Finding a Product's Harmonization Number: To look up your product's Harmonization #, visit the United States Census Bureau Schedule B Search Engine and type in your product details.

    • You can get there by clicking the blue Search #'s button in the Customs section you need to fill out when making your label, as seen here:

  • Start with a Basic Search: Once you're on the Schedule B Search Engine page, try to search for the most basic one-word description possible. For example, if you're sending a T-shirt, type in "shirt" and then click the blue 'Classify' button with the magnifying glass πŸ˜‰

  • Find the Closest Description: Next, you'll be taken to a section called "Tell Us More About" to select the closest option from the results that pop up. Click the one that best describes your item.

    • Here's how that process looks for a men's 100% cotton T-shirt (non-knitted):

  • Continue Following the Prompts: From there, continue selecting the following choices that best describe your item(s):

  • Accept the Description: When you've filled out all the necessary information, click "Accept."

  • Get Your Harmonization Number: Next, the search engine will return your Harmonization # πŸŽ‰

    • In this example, since the T-shirt is made of cotton and isn't a dress, that number will be 6205.20.3000, as seen below:

  • Enter Your Harmonization Number in Pirate Ship: Finally, once you have your number, all you need to do is type it into the "Harmonization #" section when making your customs form in Pirate Ship πŸ‘

    • If You Can't Find a Number: If the Census Bureau Schedule B Search Engine isn't returning a result for whatever reason, you can search for your item on this website: https://hts.usitc.gov/

How many digits does my Harmonization Number need?

  • Length of Harmonization Numbers: Sometimes you may notice that your Harmonization # isn't 10 digits like the one in the example above. If that's the case, this is ok! Here are some things to keep in mind:

    • HS & Schedule B Numbers Accepted: Our "Harmonization #" field in the Customs form section accepts both HS and Schedule B numbers. Numbers have to be at least 6 digits but can be many more. The more digits, the more specific the description of what’s being shipped, and often includes the country being shipped toπŸ‘Œ

    • 6 Digits at Least: You should have at least a 6-digit number. Country-specific codes can be 14 digits long, and our system also accepts these.

      • Note: You don't want to add any 0's to the end of your number to get 6 digits, because 0's at the end can technically mean different items altogether πŸ˜…
