This document specifies rules to encode formulae, and gives specific codes for 1 233 frequently-used formulae. Chinese patent medicines (CPM) are outside the scope of this document. Kampo formulae are outside of the scope of this document. This document is applicable to formula-relating databases in fields of clinical medication, scientific research and teaching, electronic medical records and prescription of traditional Chinese medicine (TCM).

Overview

ISO 20334:2018 - Traditional Chinese medicine - Coding system of formulae defines a standardized coding system for TCM formulae. The standard specifies rules to encode formulae and provides specific codes for 1,233 frequently-used formulae (1,165 in Annex B and 68 Korean formulae in Annex C). Chinese patent medicines (CPM) and Kampo formulae are explicitly outside the scope. ISO 20334:2018 is intended for use in TCM databases, electronic medical records (EMR), prescriptions and clinical, research and teaching systems.

Key technical topics and requirements

Coding principles: Uniqueness (each formula has a unique code), scalability (space for expansion) and stability (codes remain unchanged unless formula characteristics change).

Seven-layer coding structure: The code uses 10 Arabic digits arranged in seven layers that classify and identify each formula by category, action and sequence number.

Layer 1: category of agriculture/medicine - formulae use “0” (per ISO 18668‑1)
Layer 2: product code of Chinese medicines - symbolized by “6”
Layer 3: formula category - symbolized by “0”
Layer 4: main code (2 digits) - action-based categories (e.g., exterior‑releasing, purgative, harmonizing, heat‑clearing; Sasang constitution codes 41–44)
Layer 5: subdivided code (1 digit) - secondary classification under main action
Layer 6: sequence number (3 digits) - ordinal position in code tables
Layer 7: check digit (1 digit) - calculated according to ISO/IEC 15420 (see Annex A)

Coding technology: Classification is action-oriented and intended for machine-readable databases and bar-code-compatible implementations (check digit per ISO/IEC 15420).

Normative annexes: Annex A (check digit calculation), Annex B (codes of formulae), Annex C (Korean formulae codes).

Practical applications and users

ISO 20334:2018 is designed for:

Hospitals and TCM clinics implementing standardized TCM prescriptions in EMRs and e-prescribing systems

Clinical informatics and software vendors building medication databases, decision support and interoperability layers

Researchers and educators maintaining consistent formula references for teaching and scientific studies

Regulators and quality managers tracing prescriptions and monitoring safe use of formulae Benefits include improved interoperability, traceability, clearer recordkeeping, and facilitation of international academic exchange of formulae.
