In the end-of-life spare-part market, refurbished components often circulate together with brand-new surplus original stock. Without effective identification, factories may purchase refurbished goods at brand-new price, bringing hidden trouble to continuous production.

Brand-new original spare-parts retain complete original factory packaging, intact name-plate printing, clear laser-mark serial number and no scratch on metal-shell surface. Refurbished products usually show traces of disassembly, scratch repair, re-painting or replaced labels. Some vendors will erase old serial numbers and re-print new ones to disguise used goods.
For critical equipment spare-parts of power station and petrochemical projects, it is highly suggested to require suppliers to provide product-source information before order confirmation. Wanbang Global strictly distinguishes brand-new surplus, refurbished and used units, and clearly marks product status for every quotation to avoid misleading customers.
