NAICS 32311 is a domestic industry classification used for statistical and regulatory purposes, while HTS codes govern duty assessment at the border. Importers must map their products to the appropriate HTS heading — which depends on printing method, content type, and material — rather than relying on the NAICS code alone.

Stationery articles are generally blank or minimally printed paper-based goods (envelopes, notebooks, forms) intended for writing or office use, whereas commercial printing output carries substantive printed content produced to a customer's specification. The distinction affects both HTS heading selection and applicable duty rates.
