品牌所有者在为新的贸易项目制定GTIN分配策略和对现有贸易项目进行更改时，应考虑以下指导原则。

■ 包装中的产品：是否希望利益相关方（如医护人员、消费者、患者、监管机构和/或贸易伙伴）对更改前后的产品或新旧产品进行区分？

GS1标准有助于改善供应链运行，提高操作效率，并符合监管要求，以提高患者安全。本文件为管制医疗产品分配全球贸易项目代码（GTIN）提供了明确的规则。

本文件概述的规则适用于受管制的医疗行业。本文中某些规则不适用于其他行业，也未包括在《GTIN管理标准》中。两份文件中的规则已尽量保持协调统一。

本文件旨在为GS1标准的实施提供一个全球统一的框架，以提高供应链效率，确保患者安全。

全球贸易项目代码^®（GTIN^®）是用于标识需要检索预定义信息的贸易项目，以及供应链中任何可能定价、订购或开具发票的贸易项目的国际标准。

This Implementation Guideline includes separate data elements for dimensions of the transport unit.
Data titles for these data elements are Height (AI 333n), Width (AI 332n), and Length (AI 331n).

To ensure an unambiguous understanding of these data elements please follow the guidelines in this Annex.

These guidelines do not (yet) cover all possible shapes and sizes of transport units, but they provide some rules that should work for most transport units.

GS1 identification key (ID Key)

The image below shows a Logistic Label using GS1 (2D) barcodes approach to implement Scan4Transport.

The label still shows the SSCC in the GS1-128 linear barcode format as mandated by GS1 General Specifications and the Logistic Label Guideline.
This means more traditional stakeholders in the supply chain may still use the linear barcode to access information regarding the transport unit.

The label also includes a GS1 DataMatrix encoding the following information:
