Classification, made simple and accountable
Tariff classification is one of the most consequential decisions in international trade, and one of the easiest to get wrong. A single incorrect HS code can mean delayed shipments, overpaid duty, penalties and fines from HMRC. Yet most importers use guesswork, which is not a strategy.
We built TariffTel to change that. Over fifteen years we have classified more than 1.5 million products for some of the UK's largest and fastest-growing small businesses, and we put that experience into software that anyone can use. TTVerified is the expert-backed platform that pairs automation with specialist review, so every code is one a customs expert is willing to stand behind.

The principles behind every code we deliver
TariffTel is built on three commitments. They shape how we build our software, how we hire our specialists, and how we treat your data.
Accuracy
The right code is the only acceptable outcome. We apply the General Interpretive Rules, established rulings and chapter notes with rigour, then verify every decision so it stands up to scrutiny from HMRC and customs authorities.
Expertise
Software automates the research; people own the answer. Our customs specialists bring fifteen years of hands-on classification experience to every product, which is why we describe TTVerified as expert-backed, not just AI-powered.
Security & Trust
Your product data is sensitive, and we protect it accordingly. TariffTel is ISO/IEC 27001:2022 certified, independently audited by NQA across UK and EU operations, with a full audit trail behind every classification.

Credentials our customers can rely on
Independent recognition matters in a field where the answer has to be right. TariffTel was named FDEA Export Service Provider of the Year 2025, and our information security is certified to the international ISO 27001 standard.
