CRT Deflection Yoke Holder
This holder is used for mounting deflection yokes on CRT necks, aligning magnetic fields for electron beam scanning. It is a part of a cathode-ray tube, but it is not an electron gun or an RF interaction structure. Therefore, it falls under this tariff item as 'other' parts.
8540.99.90CRT Internal Magnetic Shielding
This mu-metal internal shielding sheet is placed between the CRT electron gun and deflection area to prevent external magnetic interference. It is a part of a cathode-ray tube, but it is not an electron gun or an RF interaction structure. Thus, it is classified under this tariff item as 'other' parts.
8540.99.90CRT Neck Extender Sleeve
This precision glass or ceramic sleeve extends the CRT neck for custom electron gun positioning in specialized applications, such as medical and scientific CRTs. It is a part of a cathode-ray tube, but it is not an electron gun or an RF interaction structure. Therefore, it falls under this tariff item as 'other' parts.
8540.99.90CRT Purity Glass Sample Disc
This small glass disc with phosphor coating is used during CRT manufacturing to check glass purity and contamination levels. It is a part of a cathode-ray tube, but it is not an electron gun or an RF interaction structure. Thus, it is classified under this tariff item as 'other' parts.
8540.99.90CRT Socket with Pin Contacts
This ceramic base socket with 19-pin gold-plated contacts is used for CRT neck board connections, providing filament and grid power. It is a part of a cathode-ray tube, but it is not an electron gun or an RF interaction structure. Therefore, it falls under this tariff item as 'other' parts.
