Trade Compliance Resources
Maintained reference guides for U.S. trade compliance, curated from our blog and grouped by topic. Each entry links to its canonical article, so this page is a durable index over the guides we keep current, not a second copy of them.
This is a curated reference library, not a news feed. Each entry below is a maintained guide from our blog, grouped by topic and linking to its canonical article, covering the durable mechanics of trade compliance: classification, duty math, drawback, export controls, and country-by-country tariff exposure. The blog is where we publish fast-moving analysis and event coverage; this hub is the smaller set of guides we keep as long-lived references. If you are new here, start with Core Concepts, then jump to the section that matches your work.

Frequently asked questions
What is the GingerControl resources hub?
It is a curated index of our evergreen trade compliance guides, the reference material that stays useful long after it is published: classification method, duty math, drawback, export controls, and country tariff exposure. Each entry links to the full guide on our blog at its canonical URL. Think of it as the table of contents for the durable half of our library, separate from the fast-moving news and analysis that lives on the blog.
How are these guides maintained?
Every entry here is a published blog guide that we treat as a long-lived reference rather than dated commentary. We select topics whose fundamentals hold up over time, and we revise a guide when the underlying rules or rates actually change, for example when a Section 232 rate moves or a country's tariff treatment shifts. The country tariff guides carry perishable rate numbers, so we recommend confirming current rates against CBP or the USITC before you file.
How is this different from the GingerControl blog?
The blog is the full stream: breaking policy coverage, product comparisons, how-tos, and long-tail explainers published on a fast cadence. This hub is a smaller, hand-picked subset, the guides that answer definitional and mechanics questions and stay relevant. Nothing here is a separate page or a duplicate; each link points to the same blog article, just organized into a reference structure so you can find the right guide by topic instead of scrolling a date-ordered feed.
Who are these resources for?
Importers, exporters, in-house trade compliance teams, and customs brokers who need a reliable reference on how U.S. trade rules work. Core Concepts and Duties and Tariff Mechanics suit anyone building foundational understanding. HTS Classification by Industry and Export Controls go deeper for practitioners. The Country Tariff Guides help sourcing and finance teams model duty exposure by origin.
