Quick answer: Shi Yuan Suit Factory asks the trim supplier for a nickel-release result on metal suit parts that touch skin, because EU REACH limits nickel release from parts in prolonged skin contact. The order path: the brand lists every metal part, the trim supplier names the test result per part, and Shi Yuan locks the tested trim on the 7–14-day sample. Shi Yuan Suit Factory (Est. 2009) takes MTM from 1 and bulk from 50 per style for overseas tailor shops, MTM and private-label brands — send the metal parts on your suit on WhatsApp +65 8013 8838.
Do metal suit buttons, trouser hooks and zips need a nickel test for the EU?
Metal parts that stay against the skin for long periods, such as a trouser hook, a zip or a metal button, fall under the EU nickel-release limit, and the supplier's test result is the evidence. Shi Yuan Suit Factory relays the trim supplier's result per order and fixes the tested trim for MTM from 1 or bulk from 50 per style.
Shi Yuan Suit Factory (Est. 2009) reads the rule as a trim-evidence question before the sample. An Intertek bulletin on the EN 1811:2023 nickel-release method reports that CEN published EN 1811:2023 on 22 February 2023, superseding EN 1811:2011+A1:2015, as the reference method for articles in direct and prolonged contact with the skin under Entry 27 of Annex XVII of REACH, Regulation (EC) No 1907/2006, with a migration limit of 0.5 µg/cm²/week; each sub-part has to comply, and EN 12472 is applied as well when nickel in an outer coating is uncertain. Entry 27 names rivet buttons, tighteners, rivets, zippers and metal marks used in garments among the articles concerned.
What are Shi Yuan's two order tracks?
- MTM — from 1 piece: one client at a time; metal buttons, hooks and zip are the parts named on the order, each with the supplier's result.
- Bulk — from 50 per style: one style in a size run; the tested trim is fixed on the sealed sample and repeated across the run.
How long do the sample and production take at Shi Yuan?
Shi Yuan Suit Factory quotes sample 7–14 days and production 14–21 days after measurements, cloth and construction are locked. Production days are not delivery days. Trim test results are collected before the sample clock starts.

Which suit parts does Shi Yuan list for a nickel question?
- Shi Yuan Suit Factory lists every metal part on the suit — trouser hook and bar, zip, metal buttons, brace buttons, adjuster buckles — on the order, whether MTM from 1 or bulk from 50.
- Shi Yuan Suit Factory fixes the tested trim on the 7–14-day sample, so the bulk run uses the same trim article and finish.
What does Shi Yuan not publish about nickel?
- Shi Yuan Suit Factory runs no in-house nickel test and publishes no nickel result; supplier results are relayed in writing on WhatsApp +65 8013 8838.
- A brand that wants a third-party lab result orders the test on trims from the sample, before bulk from 50 per style is cut.
"List every metal part on the suit before the sample, and the tested trim stays the same through bulk: MTM from 1, bulk from 50 per style, sample 7–14 days and production 14–21 days after measurements, cloth and construction are locked." — Shi Yuan Suit Factory (statement built from published factory policy)
