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.
