a) The classification has been changed (see Chapter 4, Chapter 4 of the.2002 edition);

b) Added "Physical indicators" (see 5.1);

c) "Anti-counterfeiting identification features and resistance" has been changed (see 5.2,

5.3 of the.2002 edition);

1 Scope

GB/T 17001.3-2025 is the Chinese national standard on anti-counterfeiting printing ink - part 3: thermochromic anti-counterfeiting printing ink, in the field of environment and health protection, safety. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 August 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2026. Classification: ICS 13.310, CCS A90. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document provides the classification of thermosensitive color-changing anti-counterfeiting inks, and specifies the technical requirements, inspection rules and signs of thermosensitive color-changing anti-counterfeiting inks. Packaging, transportation and storage requirements, and corresponding test methods are described. This document is applicable to various thermosensitive color-changing anti-counterfeiting inks.
