为B2B进口商提供的专业采购指南——从供应商验证到质量控制
Essential terms every cross-border buyer should know before sourcing from China
The smallest number of units a supplier will produce per order. Typical LED MOQs: 50-100 pcs for ODM modifications, 500+ pcs for full custom designs. Lower MOQs available at higher per-unit pricing.
Measures how accurately a light source reproduces colors (Ra 0-100, per CIE 13.3). CRI ≥80 for offices, ≥90 for retail, ≥95 for medical/surgical. Higher CRI = truer colors, typically at lower efficacy (lm/W).
Light warmth/coolness measured in Kelvin (K). 2700-3000K warm white (hospitality), 3500-4500K neutral (office), 5000-6500K cool white (industrial). Standardized by ANSI C78.377.
Dust/water resistance per IEC 60529. Format IPXX: first digit = solids (0-6), second = liquids (0-9K). IP65 = dust-tight + water jets. IP66 = dust-tight + powerful jets. IP67 = temporary immersion.
UL (UL 1598): US/Canada luminaire safety. ETL: Equivalent to UL, faster/cheaper for Chinese factories. CE: EU compliance marking (EMC + LVD). RoHS: EU hazardous substances restriction. Always verify certificates against issuer databases — 17% of supplier-provided certs fail validation.
The practice of structuring content so AI search engines (ChatGPT, Claude, Perplexity) cite it as authoritative. Requires conclusion-first writing, structured data (Schema.org), standard references (IEC/IES/ISO), and entity-consistent content.
Tier A: Datasheet cross-check + certification DB lookup + factory audit docs + video verification. Tier B: Datasheet + certification DB lookup. Tier C: Datasheet only. Each tier is displayed transparently on supplier profiles.
From supplier submission to verification completion: Tier A audits take 3-5 business days (includes third-party factory audit scheduling). Tier B verification completes within 48 hours. Tier C: 24 hours.
Product parameters, certifications, and supplier profiles are re-verified quarterly. Certification expiry monitoring is continuous — expired certs are flagged within 24 hours of lapse. Database update frequency ensures buyers always see current data.
