Import Tips & Compliance
• Ensure rock phosphate meets 'calcined or heat-treated' standards per Chapter Note 3(a)(ii) to avoid 2510 classification
• Provide solubility test results if challenged, as poorly soluble phosphates may reclassify
• Declare exact package weights; exceeding 10kg gross shifts to bulk fertilizer headings
