When the law answers the question, don't keep asking new ones.
Tariff classification specialist and co-founder of TariffWolf. I have worked on HS, HTS and ECCN classification since 2017, and I write case studies on how the GRIs and legal notes decide a code.
I'm Surajit Roy, a trade compliance professional based in India. Most of my work is tariff classification: taking a product description, a drawing or a specification sheet and finding the heading and subheading that the legal texts support.
I started in December 2017 at Portway International, assigning HTS codes and running quality checks. I have since done classification work at Avalara, where I led a team of 23, and at Sandler & Travis Trade Advisory Services, UPS and Baker Hughes, where it also covered export control classification numbers (ECCNs).
In 2026 I co-founded TariffWolf India Pvt. Ltd. and became its CTO. We are building a classification engine for tariff and export control work that keeps a human expert in the loop.
