Products classified under HTS 7011.20.85.40
Glass CRT Neck Tube
A precision-formed glass tube serving as the neck section of a cathode-ray tube (CRT) envelope, open at one end for electron gun attachment. It falls under HTS 7011.20.85.40 as an open glass part specifically for CRTs, without any fittings. These components ensure vacuum sealing and electron beam alignment in older display technologies.
CRT Faceplate Glass Blank
An open-ended cylindrical glass blank intended for final processing into the faceplate of a cathode-ray tube, providing the viewing screen surface. Classified in HTS 7011.20.85.40 as an unfinished open glass part for CRTs without fittings. It supports phosphor coating and electron beam interaction in television or monitor CRTs.
CRT Cone Glass Section
A tapered open glass cone component that connects the neck to the faceplate in CRT envelopes, essential for beam focusing. It is categorized under HTS 7011.20.85.40 as other open glass parts for cathode-ray tubes, excluding bulbs or those with fittings. Used in oscilloscope and radar display CRTs.
Open CRT Envelope Cylinder
A seamless open cylindrical glass envelope body for cathode-ray tubes, prior to sealing or fitting attachment, used in X-ray or medical imaging CRTs. Falls under HTS 7011.20.85.40 as other glass parts for CRTs. Designed for high vacuum integrity and electron deflection.
Precision CRT Stem Tube
A narrow open glass stem tube for mounting electrodes in CRT electron guns, without pins or fittings. Classified in HTS 7011.20.85.40 for other open CRT glass parts. Critical for maintaining vacuum seals in monochrome or color CRT assemblies.
CRT Phosphor Screen Glass
Open-ended glass substrate prepped for phosphor deposition in CRT faceplates, used in avionics displays. Under HTS 7011.20.85.40 as other glass parts for cathode-ray tubes, open and without fittings. Ensures high-resolution imaging through precise thickness control.
High-Voltage CRT Bulb Shell
An open glass bulb shell for high-voltage cathode-ray tubes in industrial oscilloscopes, without base fittings. Fits HTS 7011.20.85.40 as other open envelopes/parts for CRTs. Built to withstand deflection yoke pressures.
Monoscope CRT Glass Tube
Specialized open glass tube for monoscope CRTs used in TV test signal generation, without internal components. Classified HTS 7011.20.85.40 for other CRT glass parts. Features unique curvature for signal pattern projection.
Storage Tube CRT Envelope
Open glass envelope for storage CRTs in radar memory displays, designed for electron retention. HTS 7011.20.85.40 covers this as other open CRT parts without fittings. Supports persistent image hold after beam scan.
Vector CRT Neck Glass
Precision open neck glass for vector-scan CRTs in flight simulators, optimizing high-speed drawing. Under HTS 7011.20.85.40 as other CRT glass components. Engineered for minimal distortion in dynamic displays.
