FBR Digital Invoicing for the Steel Sector: Melters, Re-Rollers, Ship Breakers & Toll Manufacturing
Steel is the most rule-heavy sector in FBR Digital Invoicing: dedicated scenarios SN003 (melting and re-rolling), SN004 (ship breaking) and SN011 (toll manufacturing), a mandatory MT unit of measure, steel-sector buyer checks and minimum-value rules. Every trap decoded.
Three dedicated scenarios, not one
FBR gives the steel sector its own sandbox scenarios. SN003 covers melted and re-rolled products — billets, ingots and long bars (HS codes like 7214.1010) under sale type "Steel melting and re-rolling". SN004 covers scrap sold by ship breakers (HS 7204.1010, sale type "Ship breaking"). SN011 covers toll manufacturing — conversion charges billed by a mill that processes someone else's material (sale type "Toll Manufacturing").
All three run at the standard 18% rate, but they are not interchangeable: the sale type must match what your business actually does, because FBR validates the combination of registration profile, sale type and HS code on every invoice (error 0007 / 0052 when they disagree).
The MT rule and other steel-specific rejections
Error 0062 — quantity in steel scenarios must be in MT (metric tonnes). Invoices sent with "KG" or "Numbers, pieces, units" are rejected outright, so software should lock the UoM to MT for steel sale types and convert kilograms before posting.
Error 0056 — for toll manufacturing, the buyer must be registered in the steel sector; billing conversion charges to a non-steel buyer is blocked. Error 0101 — toll manufacturing cannot be declared under the general Services sale type; FBR forces it through SN011. And error 0059 — the declared value cannot fall below FBR's minimum notified price for steel products; the rejection message names the minimum you must meet.
Who clears which sandbox scenarios
A steel-sector manufacturer clears SN003, SN004 and SN011 in sandbox testing. Steel importers and exporters clear the general goods scenarios plus the steel trio; steel-sector distributors and wholesalers additionally see the retail scenarios in their matrix. Your registered business activity and sector on the FBR profile decide the exact list — clearing them all is what unlocks the production token.
In production the scenarioId field is dropped from the payload entirely; what remains is the correct sale type per line. A re-rolling mill that also trades purchased bars can legitimately have SN003-type lines and standard-rate trading lines on different invoices.
Making daily steel invoicing painless
Weighbridge-driven quantities mean decimals: FBR accepts up to four decimal places on quantity, so a 12.475-tonne load posts cleanly as 12.475 MT. Keep rate and value fields consistent — 18% of the exclusive value must equal salesTaxApplicable to the rupee, or FBR returns calculated-tax error 0104.
Digi Invoice ships the steel sale types, MT lock and tax auto-calculation out of the box, decodes rejections like 0062 and 0056 into plain-language fixes, and keeps billets, bars and scrap as separate stock items with their HS codes — so the operator types a weight and a rate, and the payload comes out FBR-shaped every time.
