Where this code sits in the schedule
Six digits is the last level the WCO Harmonized System defines internationally: chapter 72, heading 7203, subheading 720310. The US adds national digits below it — eight for the tariff line, ten for the statistical suffix — which is why two traders quoting “the HS code” can still disagree on the rate. Browse the ladder:
