U.S. imports of sign plates, name plates, address plates, numbers, letters and symbols of base metal (non-illuminated) (HS 831000) totaled $11.1M in April 2026, traded with 44 countries.
Importers of Sign Plates, Name Plates, Address Plates, Numbers, Letters and Symbols of Base Metal (Non-Illuminated) paid $1.3M in duties in April 2026 — an effective duty rate of 21% on $6.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataNon-illuminated identification hardware — including building address plates, machine name plates, directional signs, and individual letters, numbers, and symbols — is classified under a single 10-digit line (8310000000), provided the articles are not illuminated (which would shift them to heading 9405). The heading spans a wide range of base metals and surface finishes, from stamped steel industrial tags to cast brass architectural plaques. Classification hinges on the absence of a light source; any integrated lighting element moves the product out of Chapter 83 entirely.

The critical distinction is illumination. Heading 8310 covers non-illuminated plates, letters, and symbols. If the article incorporates a light source — such as an LED-backlit channel letter or a lighted address plaque — it is classified under heading 9405 as a luminaire or lighting fitting. Importers of combination sign-and-light products should confirm the classification with a licensed customs broker.
No. Heading 8310 does not distinguish by manufacturing method — stamped, engraved, etched, cast, or laser-cut metal plates all fall under 8310000000 as long as they are non-illuminated and serve an identification or signage function. The material (steel, aluminum, brass, etc.) also does not subdivide the single 10-digit line.
