Packaging — Export-ready Wooden Spools
Standard packaging: CHINGCUNG enameled rectangular copper wires are wound on heat-treated, fumigation-free wooden spools (ISPM 15 compliant), suitable for direct export to all global markets. The spools are robustly constructed to protect the wire during long-distance shipping and handling.
Spool options: Custom spool sizes available upon request. Wooden spools are secured with moisture-resistant wrapping and labeled per customer requirements.
Export advantage: ISPM 15 heat-treated wood — no additional fumigation required at destination ports. Safe, reliable, and environmentally responsible.
Customization: In addition to standard sizes listed above, we offer custom thickness/width combinations, non-standard dimensions, and special spool packaging. Grade 1 (single coating) and Grade 3 (triple coating) available for specific insulation requirements. Contact our technical team for consultation.
