Manufacturing & engineering is high-risk to classify
Engineered goods sit across complex section notes, material-form rules and additional-duty regimes. A single subheading can decide whether a shipment carries standard duty, anti-dumping duty or a CBAM reporting obligation — and the duty amounts involved are rarely small.
A component can be classified with its machine, under a dedicated parts heading, or under its own material. An incomplete or unassembled article with the essential character of the finished machine is classified as the machine under GRI 2(a).
Steel and aluminium are classified by form, alloy, dimension and processing. Carbon content, coating, thickness or a single finishing step can move a product between subheadings — and between duty rates.
Anti-dumping, safeguard and CBAM obligations attach to specific codes and origins. Iron, steel and aluminium are squarely in CBAM scope. The exact code decides the exposure — and the wrong one is expensive.
Assemblies, tooling, fasteners, bearings and castings produce enormous bills of materials in mixed materials. Classifying each line correctly — and consistently — is a volume problem and a judgement problem at once.
Complexity that generic tools cannot handle
A cast bracket supplied loose for a single machine model. A coil of alloy steel that crosses a thickness threshold. A hydraulic pump that is a complete article in its own right. A part-built assembly shipped knocked-down. Each demands precise data and expert judgement against the section and chapter notes.
How we classify engineered products
A rigorous, three-stage process built on deep tariff expertise and designed to get parts, materials and complete machines right the first time — at any volume.
Analysis
We work the Section XVI and XVII legal notes, the relevant chapter notes for Chapters 72–84, established rulings and the General Interpretive Rules — including GRI 2(a) for incomplete and unassembled articles — to determine exactly how each part, material or machine should be classified.
Data Collection
We gather every data point that affects the code: function and intended machine, material and alloy composition, form, dimensions and processing, carbon content, coating or finishing, assembly state, origin and the structured details needed for CBAM and anti-dumping checks.
Expert Review & Monitoring
Every code is verified by a specialist customs expert, with anti-dumping, safeguard and CBAM exposure flagged. TTVerified then monitors tariff and measure updates continuously so your codes stay correct as duties and trade measures change.
Every engineered product, classified
From raw metals and semi-finished stock to complete machinery and the smallest fasteners. TariffTel's experts handle the full spectrum of manufacturing and engineering classifications.
Classification is the foundation of CBAM reporting
The Carbon Border Adjustment Mechanism covers iron and steel, aluminium, cement, fertilisers, hydrogen and electricity — including many downstream iron, steel and aluminium articles. Whether a product is in scope is decided by its CN/HS code, so the classification itself is the trigger for any CBAM obligation.
The structured product and material data TTVerified captures during classification — alloy, form, material content and origin — feeds directly into CBAM reporting, so you are not rebuilding the same evidence twice. For large estates, TTExplore and Managed Services extend the same data discipline across your full catalogue.
Built for the complexity of engineered goods
When the duty amounts are large and anti-dumping or CBAM is in play, accuracy is not optional. TariffTel understands manufacturing and engineering classification at a level generic tools simply do not reach.

UK CBAM starts on 1 January 2027: is your commodity code about to make you a CBAM importer?
From 1 January 2027, imported steel, aluminium, cement, fertiliser and hydrogen carry a UK carbon charge. Your commodity code decides whether you are caught.
How to get accurate HS codes for clothing
Clothing is one of the most misclassified categories at customs. Here is how to get garment and footwear codes right, and keep them right.
EU forced labour ban: why knowing where and how your products are made is crucial
From 14 December 2027, products made with forced labour cannot be sold in or exported from the EU. Here's why supplier data is the part that takes time.
