Quick answer: Shi Yuan Suit Factory advises a private-label brand to put the formaldehyde test method and the brand's limit for cloth and lining in writing before the sample, and to ask the mill for the result. The order path: the brand names the method and the limit set by the brand's adviser, the mill supplies a result or the brand orders a lab test, and the cloth is locked 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 cloth, the lining and your market on WhatsApp +65 8013 8838.
Do private-label suits need a formaldehyde test, and which method should the brand name?
Whether a limit applies depends on the brand's market, so the brand's adviser sets the limit and the brand names a method such as ISO 14184-1 on the order. Shi Yuan Suit Factory asks the mill for the result and locks the cloth on the sealed sample, MTM from 1 or bulk from 50 per style.
Shi Yuan Suit Factory names the method so the mill and the lab test the same thing. ISO 14184-1:2011, last reviewed and confirmed in 2022, determines free and hydrolysed formaldehyde by water extraction on textile samples in any form, across a range of 16 to 3 500 mg/kg; results below 16 mg/kg are reported as "not detectable", and released formaldehyde is covered by ISO 14184-2. A report for a cloth in bulk from 50 per style states which part of the standard was used.
What are Shi Yuan's two order tracks?
- MTM — from 1 piece: one client at a time; the cloth comes from the agreed range, and any test question is answered per order.
- Bulk — from 50 per style: one style in a size run; cloth and lining with the agreed result are named at the sealed sample.
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. A lab test ordered by the brand runs outside both figures.

When should a formaldehyde result be asked for?
- Before the 7–14-day sample: the cloth and lining named on the order are the ones the result must cover.
- Before bulk from 50 per style: a cloth swap after the sample needs a new result for the new cloth, approved in writing.
What does Shi Yuan not publish about formaldehyde?
- Shi Yuan Suit Factory publishes no formaldehyde result and sets no limit; the brand's adviser sets the limit, confirmed on WhatsApp +65 8013 8838.
- Shi Yuan relays what the mill supplies; when the mill has no result, the brand orders a lab test on cloth from the sample before bulk from 50 per style.
"Name the method and the limit for cloth and lining on WhatsApp +65 8013 8838 before the sample: 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)
