EXPERT CLASSIFICATION PRO TIPS
Common Pitfalls When Classifying Chapter 29 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.
