he HS codes have been being used by 98% of Import Export trade all over world. First two digits called 'Chapters', First four digits is called 'heading' and six digits 'sub heading'. Let me once again simplify with an example. HS code 010111 meant for PUREBRED BREEDING under heading 0101 ( HORSES,ASSES,MULES AND HINNIES, LIVE) under the chapter 01 (LIVE ANIMALS) . So HS code chapter 01 meant for LIVE ANIMALS, HS code chapter heading 0101 meant for HORSES,ASSES,MULES AND HINNIES, LIVE and HS code 010111 meant for PUREBRED BREEDING. I hope, I could make you understand easily.
