Overview

ISO 23067:2022 - Grading system for rattan: Requirements and classification provides a harmonized framework to sort and classify rattan cane materials (poles and derivatives) by physical properties, quality and market value. Published by ISO and prepared by ISO/TC 296 (Bamboo and rattan), the standard addresses inconsistencies in national grading systems and supports transparent international rattan trade, quality assurance and product specification.

Key Topics

• Classification method
  • Rattan poles: small diameter (below 18 mm) and large diameter (18 mm and above); further divided by physical processing (natural with skin, peeled).
  • Rattan derivatives: cores (flat, flat-oval, round) and peels (with or without skin); classified by width or diameter.
• General requirements
  • Authentic botanical identity when required by buyer.
  • Canes must be straight, round, mature and seasoned to moisture content ≤ 20% (unless buyer specifies otherwise).
  • Surface treatments: oil-curing, anti-staining fungicide, bleaching or fumigation as specified.
  • No plugging, filling or covering of visible defects permitted.
• Dimension and tolerance rules
  • Small-diameter classes: 2–6 mm, >6–11 mm, >11–17 mm; large-diameter classes include 18–20 mm, >20–25 mm, etc.
  • Length measured to nearest 0.05 m; taper limit example: not exceed 3 mm for a cane length of 4.5 m.
  • Minimum internodal length: 50 mm.
• Defects and appearance
  • Definitions and limits for defects: blemish, break, bruise, check, decay, pin hole (≤0.5 mm), worm hole (>0.5 mm), shake, wrinkle.
  • Sections on prohibited vs permissible defects and visual appearance grading.
• Inspection, packing and labelling
  • Procedures for inspection of poles and derivatives, and packaging/labelling requirements to support traceability and trade.

Applications and Who Uses It

• Producers and exporters of raw rattan and rattan derivatives aiming to meet international market expectations.
• Importers, wholesalers, furniture manufacturers and craft industries needing consistent quality specifications.
• Quality inspectors, certification bodies and trade regulators applying standardized inspection, grading and labelling.
• Designers and product developers seeking reliable raw-material selection for rattan furniture and basketry.

Related standards

• ISO 23067 complements other sector-specific standards and national grading schemes; where buyers require botanical identification or specific treatments, reference to additional phytosanitary or timber/rattan handling standards may be appropriate.

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).

Introduction
The grading of products through visual, mechanical or other techniques is important for ensuring
consumer satisfaction, safety in use and for facilitating and enhancing trade along the production–
consumption chain. It usually involves inspection, assessment and sorting according to size, quality and
market value.
Rattan, an important non-timber forest product of the moist tropical regions in many Asian and West
African countries, is traded for furniture production and in the craft industry around the world. The
International Bamboo and Rattan Organization (INBAR) reported that in 2019, global imports of rattan
[2]
products reached USD 471,7 million and with the urgency to minimize plastic usages, demand
for rattan products would gradually increase. In recent times, new designs for rattan furniture and
basketry products continue to appeal to modern consumers. Many INBAR member countries are
producers and exporters of rattan products with Indonesia, China and Vietnam having increasing
shares in the global rattan trade.
Grading of rattan products is important to eliminate confusion and misunderstanding between the
sellers and the buyers both at the national and international levels. Currently, grading and classification
of rattan vary significantly from one country to another even among INBAR member countries. Other
[3]
international organizations such as the Food and Agriculture Organization (FAO) have agreed on the
need for a rattan grading standard, and suggested that such a standard could be developed based on
[4]
the work by K.M Bhat . Some INBAR member countries have adopted varied systems of grading: some
consist of five grade classes, while others have 3 or 4 classes.
Currently, no international standard on grading system is available to provide commonly accepted
criteria to sort, assess and classify rattan. The aim of developing such an international standard would
be to enhance trade and innovation in quality rattan products at the international level.
This document provides a grading and classification system for rattan. It addresses the existing
inconsistencies among producers and exporters of rattan raw materials and products among INBAR
member countries and provides a consensus on the method and system of grading and classifying
rattan and the products. This document aims to help improve international trade of rattan products
among stakeholders by providing an assurance of the quality of raw materials or products with respect
to specific aspects of quality that influences the end use.
