Import Tips
• Obtain third-party lab certification for shatter index and CSR (coke strength after reaction) specific to foundry use
• Label shipments clearly as 'Foundry Coke - HTS 2704.00.00.11' with test batch numbers to expedite CBP review
• Watch for reclassification risk if CSR values indicate blast furnace suitability over foundry application
