Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

ISO/DIS 22927:2020(E)
Introduction

The purpose of this standard is to ensure quality assurance, enhanced safety and pollution prevention

during the global trade of rare earth products.

Rare earth products (ores, concentrates, compounds, metals and alloys) have some unique chemical

and physical properties. For example, some rare earth products may readily react with O , CO , and

2 2

moisture. Also, some rare earth products, such as monazite, may emit radiation because they contain

thorium and uranium. Under certain circumstances, these features may result in accidents, or create

hazards (such as an explosion, fire, down-grading the quality of products, radiation exposure, etc.)

during transportation and storage. Indeed, several such incidents have been reported and emphasize

the possibility of harm to human health, pollution to the environment, and a reduction in product

quality. Such problems are likely to have global effects because rare earth products are transported

across borders.

It is necessary to package rare earth products properly. It is also essential to share clearly defined

information, in a readily accessible format, concerning their physical properties and traceability

during global trade. This document provides guidelines that will ensure (1) proper packaging and (2)

appropriate labelling of rare earth products. Proper packaging can prevent rare earth products from

losing their quality and causing accidents resulting from unwanted chemical reactions. Appropriate

labelling with precise information on the properties, traceability, and the ways of handling the product

can also reduce the risk of quality degradation and accidents. Compliance with this document will

contribute to ensuring quality, guaranteeing safety and preventing environmental pollution during the

global trade of rare earths.

It should be noted that there are numerous existing regulations concerning the packaging, labelling,

and shipment of materials and these must be recognized and complied with as appropriate. Depending

on circumstances, such regulations might include:

— United Nations 2017 “Globally Harmonized System of Classification and Labelling of Chemicals (GHS)”

— United Nations 2015 “Recommendations on the Transport of Dangerous Goods”

— International Atomic Energy Agency, 2012 “Regulations for the safe transport of radioactive

material: specific safety requirements. — 2012 edition”

— International Air Transport Association (IATA), 2019 “Dangerous Goods Regulations”

— International Maritime Dangerous Goods (IMDG Code)

Furthermore, local regulations concerning shipments, transport and packaging, beyond those listed

above, may apply and have to be complied.

Many jurisdictions require that a Material Safety Data Sheet (“MSDS”) accompany any shipment and

this requirement must be complied.

Rare earth — Packaging and labelling
1 Scope

This document specifies requirements for packaging and labelling of rare earth ores, concentrates,

compounds, metals and alloys that are intended for sale or free distribution. It defines requirements

for the performance, the structure of packaging and specifies the information that the labelling shall

include. These requirements will ensure quality assurance, enhance safety, and prevent environmental

pollution during the transportation and storage of rare earth products.

This document includes requirements for packaging and labelling during transactions between

companies. Packaging by companies during storage in their own plant is not covered, but it is

recommended that they follow this standard for the purpose of quality assurance, and enhanced safety.

The method of labelling defined in this standard enhances safety by indicating properties of rare earth

products and ensures appropriate management of the product by indicating the identity of suppliers.

3.3
intermediate packaging

packaging placed between the inner packaging and outer packaging if deemed necessary

3.4
outer packaging

container designed to contain inner or intermediate packaging including any protective materials

where required
3.5
protective means of packaging

means that are applied purposely to shield/protect items/products from any physical or chemical harm

and damage.
3.5.1
protecting/shielding gas

gas used in packaging, for example, argon or nitrogen, that will displace oxygen and water vapour and

will not react with the package contents and therefore prevent product degradation.

3.5.2
protecting liquid

oil or other liquid used as coating on, or to totally submerge, a product to isolate it from air and ensure

quality stability, usually used in packaging of rare earth target products.
3.5.3
vacuum packaging
method of packaging that removes air from the package prior to sealing.
3.6
minimum packaging unit

minimum independent packaging unit for sales and delivery, where items/products cannot be broken up.

4 Packaging
4.1 General principles of packaging

Packaging for rare earth products should prevent the products from being accidentally dispersed or

otherwise discharged into the environment and from absorbing moisture or gases. Solid rare earth

metals and compounds can react with water, water vapour and other gases, causing damage to the

quality of products, exothermic reaction and ignition. For these reasons, a sealed package should be

used to contain solid rare earth products. Rare earth liquid products can flow out of the packaging in

case of a package losing its integrity, possibly causing damage to products, workers and surroundings.

For these reasons, durable packaging should be used. This document specifies requirements for
