Direct proof of use
The Type 63 107 mm multiple rocket launcher appears in the 2001 War in Afghanistan record through a U.S. Army TRADOC/OEA Taliban tactics deck. In its artillery, mortars, and rockets section, the deck describes Taliban rocket employment and lists 107 mm rockets using data for the Chinese-built variant; the same slide identifies a Chinese Type 63 107 mm rocket launcher and a field-expedient 107 mm launcher.
The report supports Taliban-aligned use or fielding of Type 63-family 107 mm launch arrangements for indirect fire. It does not name a single firing date, launcher serial, Taliban unit, or impact location for a Type 63 launcher.

Timeline
The public evidence is strongest at the tactics-report level rather than the individual incident level. The TRADOC/OEA deck was built around observed Taliban tactics and lists artillery, mortars, and rockets among the Taliban's major deadly techniques, with 107 mm launchers used from vehicles, improvised stands, or wheeled mounts.
Small Arms Survey later described armed groups in Afghanistan and Iraq acquiring and using hundreds of 107 mm rockets, mainly Chinese-designed Type 63-series rockets and foreign variants. That report places Afghan 107 mm rocket use in a wider pattern of indirect-fire attacks against bases, airports, and other stationary targets, while noting that many launchers recovered in Afghanistan and Iraq were locally made rather than factory-built.

Operational context
For Taliban and allied militant forces, the Type 63-family role was short-range indirect fire rather than maneuver artillery in a conventional battery structure. The TRADOC/OEA report describes rocket weapons as cached at firing points, moved by vehicle, animal, or manpack, fired, and then followed by exfiltration; it also notes reported Taliban use of forward observers and respect for counterbattery fire.
The Type 63's technical profile fits that pattern. Weaponsystems.net describes the launcher as a light 12-tube 107 mm system for short-range area fire, and FAS describes electrically initiated 107 mm rockets used from trailer- or truck-mounted launchers as part of the same family.
