Chapter 36 zero-rates export and equated operations: goods leaving under the customs export procedure, goods processed under the processing procedure, supplies for aircraft, services tied to customs transit, and services directly connected with international carriage. The zero rate stands on confirmation — the Code lists the documents that prove an export operation. (Tax Code, Arts. 260–263 — lex.uz ↗)
