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.

    - Surge XT - open-source synthesizer with literally 10k presets built in: https://surge-synthesizer.github.io/. - Source: Hacker News / 10 months ago
  • Ask HN: Comment here about whatever you're passionate about at the moment
    Good stuff! I started getting in to this at the start of the year. Already had an old, dusty MicroKORG and MIDI interface to use it as a controller, but recently splashed out on a bigger controller as the Korg's tiny keys were hurting me - plus, I wanted something bigger to get better at piano! A couple of free soft synths I'd recommend are Surge XT, and Vital. https://surge-synthesizer.github.io/... - Source: Hacker News / almost 3 years ago
  • Obsolete (or not) DAW recommendations for windows 8?
    Https://surge-synthesizer.github.io/ and https://asb2m10.github.io/dexed/ should work like a charm. Source: about 3 years ago
  • Hi, I'm new
    To get the equivalent of a symphonic orchestra in your computer, the solution is basically money; you buy the instruments you need. In the case of synthesizers, things are much cheaper - if you put in the effort yourself. https://surge-synthesizer.github.io/ is excellent and could even be used if you wanted to make a more retro-style soundtrack. Source: about 3 years ago
  • So is serum worth the money? Can someone ELI5 why I should buy it rather than use a free synth like synth one?
    Instead of Synth1, try https://surge-synthesizer.github.io/ . It's pretty much better in every aspect except for the UI which is going to look a lot more daunting to you ;). Source: about 3 years ago
