如何從對象讀取特定數據？

Question

{"TransactionInfo":{"Date":"06\\/04\\/2018","Time":"09:29 ET","TransactionCharge":{"MonetaryValue":"0.00","CurrencyCode":{}}},"ShipmentEstimate":{"CurrencyCode":"EUR","ShipmentCharges":{"TaxesAndFees":"1.7532","AdditionalInsuranceCost":"0.00","TransportationCost":"0.00","SubTotal":"1.7532"},"ProductsCharges":{"Product":{"TariffCode":"5109.90.80.00","Charges":{"Duties":"75.0021","TaxesAndFees":"0.00","VAT":"0.00","CostOfGoods":"1250.00","SubTotal":"1325.0021"}},"ProductsSubTotal":"1325.0021"},"TotalLandedCost":"1326.7553"},"SuppressQuestionIndicator":"Y"}

如何僅獲取TariffCode的值？ 結果必須是：5109.90.80.00

<?php

$json = '{"TransactionInfo":{"Date":"06\/04\/2018","Time":"09:29 ET","TransactionCharge":{"MonetaryValue":"0.00","CurrencyCode":{}}},"ShipmentEstimate":{"CurrencyCode":"EUR","ShipmentCharges":{"TaxesAndFees":"1.7532","AdditionalInsuranceCost":"0.00","TransportationCost":"0.00","SubTotal":"1.7532"},"ProductsCharges":{"Product":{"TariffCode":"5109.90.80.00","Charges":{"Duties":"75.0021","TaxesAndFees":"0.00","VAT":"0.00","CostOfGoods":"1250.00","SubTotal":"1325.0021"}},"ProductsSubTotal":"1325.0021"},"TotalLandedCost":"1326.7553"},"SuppressQuestionIndicator":"Y"}';
$array = json_decode($json, true);

echo $array['ShipmentEstimate']['ProductsCharges']['Product']['TariffCode'];
