Last updated: July 2026 dataGlass ophthalmic lenses for eyewear are a precision optical product where material composition — mineral glass rather than plastic or polycarbonate — is the primary classification criterion. Italy leads US imports under this heading, followed by Taiwan and India, reflecting both European heritage craftsmanship and Asian manufacturing capacity. All unmounted glass spectacle lenses enter under a single 10-digit line (9001400000), simplifying tariff treatment but placing the classification burden on the glass-versus-other-material distinction at the HS6 level. Importers should verify lens material documentation carefully, as misclassification between this heading and 900150 is a common audit trigger.

The material composition of the lens substrate is determinative. Glass lenses fall under 900140, while lenses of any other material — including CR-39, polycarbonate, or high-index plastic — are classified under 900150. Importers should retain manufacturer material certifications and lab test data to support the declared classification, especially when sourcing from suppliers that produce both types.
Imports of glass spectacle lenses from China may be subject to Section 301 tariffs. Importers should confirm the applicable List and rate with a licensed customs broker, as Section 301 coverage and exclusion status can change. Italy and Taiwan, the leading suppliers, are not currently subject to Section 301 measures on this product.
