GingerControl HTS Classifer
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.

Balsamiq is famously, deliberately low-fidelity. Everything looks like a napkin drawing, which is the point, because nobody argues about font choices when the mockup is gray boxes. - Source: dev.to / 3 months ago
Usually my own way of working is to use Balsamiq[0] to have a visual prototype to test out flows, Figma|Sketch for the UI specs, then to just code it. Kinda the same when drawing where you just doodle until you have a few workable ideas, iterate of these to judge colors and other things, and then commit to one for the final result.

You can still produce something useful even if youโre not a professional designer. For example, you can use a rapid wireframing tool like Balsamiq (my favorite) or Excalidraw. With such tools, you can sketch an idea quickly without spending time on minor visual details. Or, use a whiteboard or good old pencil and paper. Any sketch is better than nothing. - Source: dev.to / about 2 years ago

I think the best practical approach for designing UIs is to download (and buy) Balsamic[0] and use that to design UIs. Cut through the nonsense of colours and pixels in the first instance and just lay things out logically and simply. [0] https://balsamiq.com. - Source: Hacker News / over 2 years ago
