How to read this code

3824.91 is the six-digit HS subheading. Your destination country extends it to 8–10 digits and assigns the duty rate. India's preferential trade agreements (UAE CEPA, Australia ECTA, and others) can reduce or zero out that duty for many goods — check our import guides for your market.
