ISO/IEC DIS 17367:2021(E)
Introduction

The ‘Supply Chain’ is a multi-level concept that covers all aspects of taking a product from raw materials

to a final product, including shipping to a final place of sale, use and maintenance and, potentially,

disposal. Each of these levels covers many aspects of dealing with products, and the business process

for each level is both unique and overlaps other levels.

This document has been created in order to ensure compatibility at the physical, command and data

levels with the four other documents, under the general title Supply chain applications of RFID. Where

possible, this compatibility takes the form of interchangeability. Where interchangeability is not

feasible, the documents within this suite are interoperable and non-interfering. The documents within

the complete series of Supply chain applications of RFID include:
— ISO/IEC 17363, Supply chain applications of RFID — Freight containers

— ISO/IEC 17364, Supply chain applications of RFID — Returnable transport items (RTIs) and returnable

packaging items (RPIs)
— ISO/IEC 17365, Supply chain applications of RFID — Transport units
— ISO/IEC 17366, Supply chain applications of RFID — Product packaging
— ISO/IEC 17367, Supply chain applications of RFID — Product tagging

These documents define the technical aspects and data hierarchy of information required in each layer

of the supply chain. The air-interface and communications protocol standards supported within the

supply chain applications of RFID documents are ISO/IEC 18000. Commands and messages are specified

by ISO/IEC 15961 and ISO/IEC 15962. Semantics are defined in ISO/IEC 15418 and syntax is defined in

ISO/IEC 15434.

Supply chain applications of RFID — Product tagging
1 Scope

This document defines the basic features of RFID for use in the supply chain when applied to product

tagging. In particular it:

— Provides specific recommendations about the encoded identification of the product.

— Makes recommendations about additional information about the product on the RF tag.

— Makes recommendations about the semantics and data syntax to be used.

— Makes recommendations about the data protocol to be used to interface with business applications

and the RFID system.

— Makes recommendations about the air interface standards between the RF interrogator and RF tag.

This document only covers the tagging of products and does not address a products packaging.

4 Concepts

Figures 1 and 2 give a graphical representation of supply chain layers. They show a conceptual model

of possible supply chain relationships - not a one-for-one representation of physical things. Although

several layers in Figure 2 have clear physical counterparts, some common supply chain physical items

fit in several layers depending on the use case. For example, as shown in Figure 2, a repetitively used

pallet under constant ownership would be covered by ISO/IEC 17364 as an RTI; a pallet that is part

of a consolidated unit load would be covered by this document as a transport unit; and a pallet that is

integral to a single item would be covered as product packaging by ISO/IEC 17366.

The term “supply chain layers” or levels, is a multi-level concept that covers all aspects of taking a

product from raw materials to:
— A final product
— To shipping
— To a final place of sale, use, maintenance
— Potentially, returned goods and disposal

Each of these levels covers many aspects of dealing with products and the business process for each

level is both unique and overlaps other levels.

The Item Level through Freight Container Level layers are addressed within the suite of standards for

“supply chain applications of RFID” and are intended to enhance supply chain visibility. The Movement

Vehicle Level is the purview of ISO/TC 204/WG 7, and is not a part of this series of standards.

Layer 0, the Product level layer in Figure 2, is the subject of this document.

Product Level tags can be distinguished from following, or preceding, layer tags by the use of a Group-

Select methodology contained in the RFID interrogator/reader. This Group-Select function allows the

interrogator, and supporting automated information systems (AIS), to quickly identify Product Level tags.

5 Unique item identifier
5.1 General

Unique item identification is a process that assigns a unique data string to an individual item, or in

this case, to an RFID tag that is associated to the item. The unique data string is called the unique item

identifier. Unique item identification of items allows data collection and management at a granular level.

The benefits of having granular level data are evident in such areas as maintenance, retail warranties

and enabling electronic transactions of record. The benefits are only possible if each tagged item has a

unique identity.

Items that are not uniquely identified would not normally be tagged at the item level. Items to which

unique item identifiers have been assigned are said to be serialized items. Low cost consumable items

would normally be tagged at the package, or higher, level.

The unique item identifier (UII) provides granular discrimination between like items that are identified

with RFID tags or barcodes. The Unique Tag ID (as defined by ISO/IEC 15963-1) is a mechanism to

uniquely identify RFID tags and is not the unique product identifier defined in this document.

The minimum data elements required for unique identification are an issuing agency code (IAC), a

unique enterprise identifier (Company Identification Number, CIN) assigned by the IAC and a serial

number (SN) that is unique within that enterprise identifier.

The unique identifier of ISO/IEC 15459 provides identification schemes for various layers of the supply

chain, from Layer 0 (products) up to Layer 3 (returnable transport items).

---------------------- Page: 9 ----------------------
ISO/IEC DIS 17367:2021(E)
5.2 UII data elements

Unique identification is provided by the minimum of the following three components:

1. Issuing Agency Code (IAC)
2. Company Identification Number (CIN)
3. Serial Number (SN)

The registration authority, as defined by ISO/IEC 15459, assigns the IAC. The IAC assigns the CIN. The

company identified by the CIN assigns the serial number (SN). The serial number component can be

composed of multiple parts – but in all cases must be a unique identifier within the CINs domain.

When using ISO/IEC 15418, the unique identity, as defined by IAC CIN SN, is preceded by an applicable

MH10.8.2 Data Identifier (DI). Any applicable Data Identifier from ISO/IEC 15418 is allowed.

It is strongly recommended that once the UII has been constructed and encoded on an RFID tag that it

be write-protected.
5.3 Data Carrier

The data carrier / air interface shall be ISO/IEC 18000-63 or ISO/IEC 18000-3, Mode 3.

An ISO/IEC 18000-63 or ISO/IEC 18000-3 Mode 3 tags’ memory is structured in three user-accessible

memory banks;

1. MB01 (UII); for the purpose of this specification, contains the ISO/IEC 18000-63-defined constructs

of the Protocol Control bits (PC), optional Extended PC bits (XPC) and the Unique Item Identifier (UII).

1.1. The PC bits contain flags to indicate the numbering system of the tag to be either ISO or GS1,

and the existence of XPC bits and MB11.

1.1.1. When ISO is indicated, the PC bits contain an Application Family Identifier (AFI) that

indicates the data family of the UII.
1.1.1.1. The AFI is managed by the directives of ISO/IEC 15961 and listed in the
ISO/IEC 15961 Data Constructs Register.

NOTE MB01 may include additional information, like tag and item flags, sensor data, and other

item information as indicated by the PC Bits.
2. MB10 (TID); identifies the tag according to ISO/IEC 15963-1.

3. MB11 (USER); contains user information as specified by the AFI and/or the Data Storage Format

Identifier (DSFID). MB11 is optional.

As defined by the AFI, the UII format may be specified by a DSFID. The DSFID is specified and managed

by the directives of ISO/IEC 15962 and listed in the ISO/IEC 15962 Data Constructs Register.

5.4 Formats and encoding
5.4.1 General

The following sub-clauses specify the unique item identifier methodologies that are allowed.

5.4.2 GS1 EPC bitstream encoding

For GS1 EPC encoding, the numbering system identifier toggle, shown as Standard toggle (T) in

Figure A.2, shall be set to 0 (GS1). The UII shall then be an electronic product code (EPC) as specified

by GS1 TDS.

ISO/IEC DIS 17367:2021(E)
5.4.3 ISO/IEC 15418 (ANS MH10.8.2) DIs: Monomorphic 6-bit UII encoding

The numbering system identifier toggle, shown as Standard toggle (T) in Figure A.2, shall be set to

1 (ISO).

An ISO/IEC 15418-based UII, consisting of an applicable DI and item information, shall be encoded

according to the AFI selected, as that AFI is defined by the ISO/IEC 15962 appointed registration

authority.

NOTE AFIs “0xA6”, “0xA7” and “0xA8” that currently indicate HAZMAT, will be requested to be removed

from use, and potentially reassigned. The XPC HAZMAT flag shall be used to denote HAZMAT material.

The first DI in the UII datastream shall be globally unique and contain the IAC, CIN and SN. It is strongly

recommended that only one DI, and its data, be used in the UII datastream. In all cases, the UII shall be

defined by the first DI in the UII datastream.
When used, multiple DIs shall be separated by the control character (0x1D).
The messages should be terminated with the control character O (0x04).
See Annex A for examples.
5.4.4 ISO/IEC 15418 (ANS MH10.8.2) DIs: Monomorphic UTF-8 8-bit encoding

The numbering system identifier toggle, shown as Standard toggle (T) in Figure A.2, shall be set to

1 (ISO).

The UII is encoded using UTF-8 encoding as specified by an appropriate AFI as shown in the Data

Constructs Register.

The first DI shall be globally unique and contain the IAC, CIN and SN. It is strongly recommended that

only one DI, and its data, be used in the UII datastream. In all cases, the UII shall be defined by the first

DI in the UII datastream.
When used, multiple DIs shall be separated by the control character (0x1D).
The messages should be terminated with the control character O (0x04).

Optional data stored in MB11 shall use an AFI-defined, ISO/IEC 15961-registered data format.

See Annex A for examples.
5.4.5 DSFID for ISO/IEC 15434 messages

See the Data Constructs Register of ISO/IEC 15961 for Data Format 03 and 13 definitions, and for the

specification for DSFIDs.
5.4.6 UII bitstream encoding

The numbering system identifier toggle, shown as Standard toggle (T) in Figure A.2, shall be set to

1 (ISO).

The UII is encoded as a bitstream, as specified below, identified with the appropriate AFI, as registered

in the ISO/IEC 15961 Data Constructs Register.

The UII bitstream encoding, as shown in Table 1, consists of the following elements:

1. The IAC and CIN shall be encoded as specified by the ISO/IEC 20248 Data/Domain Authority (DAID)

encoding.

NOTE The ISO/IEC 20248 encoding results in encoded data lengths of 32, 40 or 48 bits. This is to provide

bit-length efficiency as the IAC and CIN, as specified by ISO/IEC 15459, is of variable length.

2. The 8-bit UII Identifier, as shown in Table 2.

5 - 0x05 Freight container

For proprietary use, a UII ID number beyond those listed in Table 2 can be used by an entity identified

by an IAC CIN SN.

NOTE There is currently no process available to assign additional UII Identifiers.

3. Use-TID-for-Serialisation flag:
3.1. When set to 0 , the UII serialisation is stored in MB01.
3.2. When set to 1 , the UII serialisation shall be the TID as stored in MB10.
NOTE The TID is specified to be unique by ISO/IEC 15963-1 and ISO/IEC 18000-63.
4. UserMem-DSFID Flag:

4.1. When set to 0 , the data stored in MB11 shall start with an ISO/IEC 15961-registered DSFID.

4.2. When set to 1 , the data stored in MB11 uses a proprietary format.
5. UserMem-word-count, providing for a user memory length of 4080 bits.

NOTE ISO/IEC 18000-63, ISO/IEC 15961 and ISO/IEC 15962 specifies methods for longer User Memory.

6. UII serialisation.

The UII serialisation length, when stored in MB01, is the UII length (which is indicated by the PC bits)

minus the lengths of the above elements, which are variable due to element 5.

Annex A
(normative)
Encoding
A.1 General

This document recommends four possible forms of encoding for ISO/IEC 18000-63 and ISO/IEC 18000-3,

Mode 3 RF tags:

• A GS1 EPC compliant form for either or both the Unique Item Identifier (UII) in Memory Bank “01”

and User Memory in Memory Bank “11”.

o The segmentation of ISO/IEC 18000-63 and ISO/IEC 18000-3, Mode 3 tags is illustrated in

Figure A.1 below.
o EPC encoding is detailed in the GS1 EPC Tag Data Standard.
• A structure employing ISO/IEC 15962, Format 13 (relative OID).

• A simplified structure, encoding an entire ISO/IEC 15434 message as a unit, employing a “no

directory”, encoded in either six-bit or UTF-8, as defined in ISO/IEC 15962 and as described in the

remainder of this annex.
• Bit stream encoding.
A.2 Tag structure

Each of these encoding forms can be unambiguously discerned by the content of bits 0x17 through 0x1F

of Memory Bank “01”, as illustrated in Figure A.2, and bits 0x00 through 0x1F of Memory Bank “11”.

NOTE Table A.1, above, is six-bit encoding created through the simple removal of the two high-order

bits from the ISO 646 8-bit ASCII character set, save the shaded values. The shaded values are re-assigned, as

provided, to minimize the bit count when using the ISO/IEC 15434 envelope.

The values in Table A.1 are not to be used without a re-issuance of this document that

reflects the defined values and functionality. An example would be a decision of the GS1 community

to use this encoding and petitioning for the encoding of an ECI. Additionally, the presence of one or

more of these characters might signal a different behaviour on the part of the decoder. While these

values are not used in this iteration of this document, they should not be used for any other

purpose than defined by this document.
A.3 Tag memory banks

Tag memory shall be logically separated into four distinct banks, each of which may comprise one or

more memory words. A logical memory map is given in Figure A.1. See ISO/IEC 18000-63 for details. A
