Do these rules depend on where the frame is made?

Mostly they depend on the product code on the customs declaration, the destination market and the importer. The country of production matters for tariffs and default emission values, but the obligation sits with the importer.

Is this legal or customs advice?

No. Rules change and the details depend on the importer and the customs code. Confirm with your customs broker or the authority in your market before you order.

Import Rules for Fabricated Steel Frames

Last reviewed 19 October 2026 · Editorial standards

Import rules sit outside the drawing. They decide what the importer must declare, pay or prove, and they are written for the importer of record. The table lists the rules we cover by market and says who carries the obligation.

Rules by market

Market	Rule	Who carries it	What the importer needs from the shop
European Union	Carbon Border Adjustment Mechanism (CBAM)	The EU importer or its authorised declarant	Net mass by customs code, plate origin, mill emission data if actual values are wanted
European Union	CE marking of structural steelwork (EN 1090-1, Construction Products Regulation)	The manufacturer places the mark, the importer checks it	Factory production control certificate, declaration of performance, label
United States	Section 232 duties on steel and derivatives	The US importer of record	Melt and pour origin, net mass, steel content
United States	Build America, Buy America on federally funded work	The contractor and the contracting officer	Origin proof for each step of manufacturing

The list of detail pages appears below as pages go live. Two existing guides cover neighbouring ground: Section 232 and imported steel frames and melt and pour origin.

How to use these pages

Find the customs code first. Every rule above follows the code on the declaration, not the product name. The HS code guide shows how frames and skids usually land.
Work out your annual tonnage by net mass. Several rules have thresholds.
Put the proof you need on the RFQ, so each quote prices the same paperwork.
Confirm the position with your customs broker. Do not rely on a shop to decide it.
