Source approach
We prefer primary, official and manufacturer sources for requirements and technical specifications.
- GS1 — Standards and identification/data-quality context.
- ASCM — Supply-chain and inventory-management reference material.
- U.S. Small Business Administration — General small-business planning context.
- Local regulatory and tax authorities — Current jurisdiction-specific requirements where applicable.
Local requirements
Requirements can change by jurisdiction and over time. Verify current law, codes, permits, contracts, workplace procedures and manufacturer documentation before acting on safety-critical or regulated questions.
