Frequently Asked Questions

What are Schedule B codes?

Schedule B is the US government's export classification system, maintained by the Census Bureau. Every exported physical commodity must be assigned a 10-digit Schedule B code for AES (Automated Export System) filing.

How do Schedule B codes differ from HTS codes?

Schedule B codes are for exports; HTS/HTSUS codes are for imports. They share the first 6 digits (HS level) but diverge at the 8- and 10-digit levels, which are US-specific.

Do Schedule B codes map to NAICS?

Yes. The Census Bureau provides NAICS cross-references in both the raw Schedule B file and the concordance XLSX. Each detail page on this site shows the associated NAICS code when available.

How often are Schedule B codes updated?

The Census Bureau releases a new Schedule B annually (current: 2026). The 10-digit codes may change between years as new commodities are defined or old ones are retired.
