EXPERT CLASSIFICATION PRO TIPS

Common Pitfalls When Classifying Chapter 38 Goods

  • Always review WCO Section and Chapter Legal Notes before assigning 4-digit headings.
  • Distinguish carefully between unprocessed raw materials and further prepared or processed articles.
  • Verify Partner Government Agency (PGA) flags for agriculture, food, or chemical items.
  • Cross-reference official CBP CROSS rulings for binding precedents on mixed or composite goods.
