Product Details: What is a Schedule B?

With the countless buying and selling that occurs each and every day around the world, you would think there would be a means of categorization and organization. There is, thanks to the U.S. government.

The U.S. Census Bureau under the Department of Commerce has developed a coded system that helps businesses promptly identify “articles,” their word for goods or items. This helps ease the exchange of said items so that exporters can expedite transactions and maintain the proper forms and records.

No doubt, our site offers as much information about a product as we can obtain given our resources. On each product page you will find a section labeled “Product Details.” In it you will often find that product’s Schedule B.

So what exactly is a Schedule B? According to, a Schedule B is a “10-digit number used in the United States to classify physical goods for export to another country. The Schedule B is based on the international Harmonized System (HS) of 6-digit commodity classification codes. There is a Schedule B number for every physical product, from paperclips to airplanes.” Couldn’t have said it better ourselves (especially with ending on ‘airplane’).

For all the most common inquiries, we suggest you go to’s FAQ page.

And while perusing the above link would suffice to answer the question, we figured we’d go a step further. Let’s use an item on our site to illustrate the 10-digit Schedule B.

We offer a lot of hardware. One of the many bolts we sell is the Military Standard MS20004-15 – a steel, internal wrenching bolt.

The MS20004-15 bolt has the following Schedule B code: 8803.30.0010. The “88-” refers to the 88th chapter of the Schedule B (there are 97 in total). Chapter 88 is labeled “AIRCRAFT, SPACECRAFT, AND PARTS THEREOF.” Based on these first two digits alone, you already know that this bolt is made especially for the use in aircraft installations.
