Definition
A standardized numeric code that classifies a product for customs, determining its duty and controls.
The Harmonized System is a globally standardized classification maintained by the World Customs Organization. Its six-digit codes are shared worldwide, with countries adding further digits for national tariff and statistical detail.
The HS code drives the duty rate, applicable taxes, licensing, and trade controls for a product, so correct classification is fundamental. Misclassification can mean overpayment, penalties, or shipment holds, which is why forwarders and brokers scrutinize it closely.
