CodeHTS helps mid-market importers and manufacturers classify products using the Harmonized Tariff System (HS & HTS), including US HTSUS codes, EU TARIC codes, UK Commodity Codes, Canada Tariff Codes, Australia HS Codes and Singapore HS Codes. Whether you're importing from China, Vietnam, Mexico or other countries, our tool automatically suggests the correct code, calculates applicable duties (including Section 301 and Section 232 tariffs), and flags potential compliance risks.
Stop wasting time manually looking up HTS codes or overpaying tariffs due to incorrect classification. With CodeHTS you get instant duty estimates, monthly alerts when tariff rates change, and professional PDF reports ready for your accountant or customs broker.
Ideal for companies that source internationally but don't have a full-time customs compliance team. Simple enough for operations managers, powerful enough to deliver real savings every month.

Don't do bootcamp. Start with something like https://freecodecamp.org and take a few lessons. Try to build something from that and see how motivated you are. If you see some progress and this thing still excites you, then may be find an engineer (a friend/co worker etc) who can guide you a bit as you continue to build something. Start small and stay away from bootcamps (my 2 cents). - Source: Hacker News / over 2 years ago
