Yes. Mouth-blown or cylinder-drawn glass used in historic restoration projects — often called antique glass or restoration glass — is a drawn or blown glass sheet and classifies under 7004 provided it has not been further worked beyond permitted surface treatments.

The manufacturing method is the classification criterion: drawn and blown glass goes under 7004, float glass under 7005. The two headings carry separate tariff lines that may have different duty rates, so confirming the production process with the manufacturer is important before filing an entry.
