Importing and Exporting in the US

Importing and exporting can help your business expand at home or abroad, but it’s important to follow all laws and regulations. U.S. Customs and Border Protection (CBP) has basic information on importing and exporting.

Importing

Imports are any resources, goods, or services that producers in one country sell to buyers in another country. CBP offers tips for new importers, including those who have recently started importing or who would like to know more about the process. Some types of goods and services require a license or permit to import into the U.S. as a part of your business.

Exporting

Exports are any resources, intermediate goods, or final goods or services that a buyer in one country purchases from a seller in another country. The International Trade Administration provides tools, assistance, and expert knowledge to help your company grow in the global marketplace. Depending on the good or service, you may need a license or permit to export it from the U.S. as a part of your business.

Obtain an Import License or Permit

In most cases, you will not need a license to import goods into the U.S. But, for certain goods being imported, some agencies may require a license, permit, or other certification. Follow this checklist to avoid problems when importing:

• Check the requirements of federal agencies. Guidelines from U.S. Customs and Border Protection (CBP) describe the types of items that may require a license or permit, with contact information for the related agency.
• Contact the local port of entry you’ll use to import your goods for import requirements and other information about the process.
• Even if you do not need an import license, you must fill out CBP entry forms within 15 calendar days of the date that your shipment arrives at a U.S. port of entry. Make sure to provide your importer number on all these forms.

Your importer number is your IRS business registration number. If you do not have this number or you do not own a business, then your importer number is your Social Security number (SSN).
You may also request a CBP assigned number by completing CBP Form 5106 and presenting it to the entry branch at a CBP port of entry

Get an Export License or Permit

Most items exported to a foreign buyer will not require an export license. However, all items are subject to export control laws and regulations. The best way to find out if an item requires an export license is by checking which agency has jurisdiction over, or regulates, the item you are trying to export. Search this list of federal departments and agencies to find out whether you need an export license for your product.
To avoid any problems, follow the U.S. Customs and Border Protection’s (CBP’s) exporting requirements or contact the local port of entry used to export your goods.
