Import Tips
• Distinguish from pure polyphosphoric acids (>84% P2O5) via assay reports; CBP may require independent testing
• Declare as 'polyphosphoric acids' if chain length >1; affects duty but stays in same base heading
• Monitor for seasonal fertilizer tariffs; bulk imports need warehouse bonds for deferred duties
