Frequently Asked Questions
- Are the first 6 digits of an HS code the same worldwide?
- Yes. Under the World Customs Organization (WCO) Harmonized System, the first six digits are standardized globally, while each country adds 2 to 6 national tariff suffixes for duty rates and statistical reporting.
- Why check 6-digit HS headings before quoting DDP or air/sea freight?
- Different HS subheadings trigger vastly different Section 301 tariffs, anti-dumping duties, or mandatory safety lab tests (UL, CE, FCC, NOM, SASO). Locking in the heading early prevents clearance surprises.
