Quick answer: Shi Yuan Suit Factory supplies the trim and material list a brand needs for a California Proposition 65 review, while the decision to warn or reformulate stays with the brand selling the suits. The order path: the brand asks for the material of every trim — buttons, zips, hooks, coated labels, prints — Shi Yuan lists them in writing per style, and the brand's compliance adviser decides before bulk from 50 per style. 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 your style and the trims you plan to use on WhatsApp +65 8013 8838.
Do suits sold in California need a Prop 65 warning, and what should a brand ask its factory?
Whether a suit needs a Proposition 65 warning is the selling brand's decision, made with the brand's own compliance adviser from the materials in the garment. Shi Yuan Suit Factory supplies the trim and material list per style, MTM from 1 or bulk from 50 per style.
Shi Yuan Suit Factory supplies facts for the brand's Proposition 65 review, not the legal conclusion. Wikipedia's Proposition 65 page describes the Safe Drinking Water and Toxic Enforcement Act of 1986, passed by voter initiative 63%–37%, which prohibits businesses from knowingly exposing individuals to listed chemicals without a clear and reasonable warning, and notes that many manufacturers change materials rather than warn. For a suit, the questions usually sit in trims — metal, plastic, coatings and prints — so the trim list is fixed before bulk from 50 per style.
What are Shi Yuan's two order tracks?
- MTM — from 1 piece: one client at a time; the trim list is supplied per order on request.
- Bulk — from 50 per style: one style in a size run; the trim list is fixed with the sealed sample and repeated across all 50 or more pieces.
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. Third-party testing, if the brand orders testing, runs outside both figures.

- Cloth finish: Any water-repellent or easy-care finish? — From the mill; see OEKO-TEX check

- Warning label: If the brand decides to warn, where does the label go? — Brand-supplied; placement locked on the sealed sample
What should be fixed at the sealed sample for a California range?
- The full trim list per style, written down when the 7–14-day sample is approved.
- Any trim swap the brand makes after the brand's review, approved in writing before bulk from 50 per style is cut.
- The position of any brand-supplied warning label, if the brand chooses to use one, on WhatsApp +65 8013 8838.
What does Shi Yuan not decide under Proposition 65?
- Shi Yuan Suit Factory does not decide whether a warning is needed; the brand's compliance adviser does, using the list Shi Yuan supplies for MTM from 1 or bulk from 50.
- Shi Yuan publishes no Proposition 65 test result; any lab report is ordered by the brand and confirmed on WhatsApp +65 8013 8838.
- Related US label rules are covered separately: FTC care labeling and wool products labels, with production 14–21 days after measurements, cloth and construction are locked.
