## 1. Executive Summary & Core Engineering Scope
Square perfume bottles from China: stock square flacons in 30 / 50 / 100 ml from 500–1,000 pieces, custom square moulds at USD 350–4,450 per set and 10,000+ pieces, decoration minimums (print 2,000, spray 3,000–5,000, plating 10,000), and the cap options — Surlyn, wood, zamac (zinc alloy), ABS,

A square flacon is the fragrance shape that reads most 'designed' and is hardest to make well: corners concentrate stress in the glass, flat faces show every speck, and the cap has to sit square to the body or the whole thing looks wrong from across the room. This guide covers the stock square shapes you can start on, what a custom square mould costs and takes, the decoration minimums a square carries, and the cap question — Surlyn, wood, zamac, ABS or aluminium — with the numbers.

A stock square perfume flacon in 30 / 50 / 100 ml starts around 500–1,000 pieces undecorated on a public mould, about 2,000 screen-printed and 3,000–5,000 sprayed; your own square shape is a glass mould at USD 350–555 per set (USD 2,200–4,450 for a 4–8 cavity set, full programmes commonly USD 8,000–20,000), 10,000+ pieces and a 90–120 day programme . Caps: sprayed ABS from 2,000–5,000, Surlyn (glass-like ionomer) and wood in the low thousands as a typical partner-factory range, zamac (zinc alloy) plated or magnetic at 5,000–10,000, with plating line minimums around 10,000. The neck is the same as a round flacon — FEA 15 crimp or 15/415 / 18/415 screw — so the pump does not change.

Glass wants to be round. A cylinder blows to an even wall; a square parison has to fill four corners, so the glass is thinner at the corners and thicker at the face centres unless the mould and the forming method are chosen for it. Three consequences drive everything below. Corners concentrate stress , so a square flacon is drawn with radiused internal corners and annealed properly — internal stress is checked on a polariscope to GB 4545 and thermal shock to GB/T 4547 (55°C to 20°C water), because a rushed anneal is what makes a square bottle crack on the shelf weeks later. Flat faces show every flaw : clear perfume glass is rejected harder than jar glass, with the A face allowed only 1–2 specks or bubbles of ≤0.5 mm and none on the logo, which is why sprayed minimums sit above skincare glass. And thick bases are press-formed : the heavy square base that makes the shape feel expensive is formed by press or narrow-neck press-and-blow, not simple blow-blow. The glass grades, forming methods and defect limits are on glass bottle specifications .

Partner glassworks hold public-mould square and rectangular flacons in the commercial sizes, in super-flint or crystal-white glass for a clear bottle and standard flint where the bottle will be sprayed. They carry the same necks as round stock — FEA 15 crimp or 15/415 / 18/415 screw — so the pump, collar and cap references from a round programme carry straight over. Dimensions below are the typical partner-factory range for a square flacon with its cap; a square of the same capacity is shorter and broader than a cylinder.

Stock samples are usually free with courier at your cost, in 7–10 days; production on stock glass is 15–25 days at the factory gate. The full route list is on perfume bottles wholesale vs custom .
