Four traps in Chapters 84 & 85
Electrical and electronics goods carry some of the densest legal notes in the entire tariff. A code that looks obvious can be wrong on principal function, on a parts rule, or on a duty measure that only applies to one subheading.
Machines and apparatus split between Chapter 84 (mechanical) and Chapter 85 (electrical), with the Section XVI notes governing both. For multifunction and composite machines, the "principal function" rule forces a single heading — and getting that judgement wrong shifts the whole code.
Is it a part, an accessory, or a complete article? Under General Interpretive Rule 2(a), an incomplete or unassembled item with the essential character of the finished product is classified as finished. The part-versus-accessory line and dedicated parts headings change the code — and the duty.
Many ordinary electricals — encryption hardware, sensors, certain semiconductors and power components — are dual-use and controlled for export. The HS code is the starting point for screening, so a vague code can mean a controlled item ships without a licence.
Anti-dumping and safeguard duties bite at specific commodity codes — solar panels, e-bikes, and certain components. The precise code and origin decide whether extra duty applies, so a misclassification can trigger an unexpected HMRC demand.
Complexity that generic tools cannot handle
A multifunction industrial controller that prints, scans and connects. A lithium-ion battery module destined for an e-bike. An LED luminaire with integrated driver electronics. A semiconductor that is also a controlled dual-use item. Each demands precise technical data and expert judgement under the Section XVI notes.
How we classify electrical & electronics products
A rigorous, three-stage process built on deep customs expertise and designed to eliminate errors before they reach your supply chain — including the export-control and anti-dumping flags that generic tools miss.
Analysis
We work through the tariff books, the Section XVI legal notes and established rulings, applying the General Interpretive Rules to decide the heading. For multifunction machines that means resolving the principal function; for components it means applying the parts and GRI 2(a) rules correctly.
Data Collection
We capture every data point that affects the code: function and operating principle, voltage and power ratings, component bill of materials, whether the item is a part or complete, state of assembly, materials and country of origin — the detail large electronics BOMs demand.
Verification & Monitoring
Every code is verified by a specialist customs expert and flagged where it touches export controls, anti-dumping measures or ITA zero-rating. TTVerified then monitors tariff and duty changes continuously, so your codes stay correct as measures and product specifications evolve.
Where the code carries real exposure
In electricals, a commodity code is rarely just a duty rate. The same code can decide whether an export licence is required and whether anti-dumping duty applies. TariffTel's experts treat both as part of the classification, not an afterthought.
TariffTel's tariff code accuracy is unbeatable. When high standards of compliance are crucial in your organisation, businesses need a solution that guarantees accuracy.
Every electrical & electronics category, classified
From semiconductors and batteries to LED lighting, cables and finished machines. TariffTel's experts handle the full spectrum of Chapter 84 and 85 classifications — including the parts, dual-use and anti-dumping edge cases.
Built for the complexity of electronics trade
TariffTel won the FDEA Export Service Provider of the Year 2025 for a reason. We understand electrical and electronics classification — and the export-control and anti-dumping exposure that comes with it — at a level generic tools simply do not reach.
