Brand positioning and origin

LONGDA is a zipper brand based in Dongguan, Guangdong, in the manufacturing belt that serves both domestic brands and export buyers. The business is oriented towards OEM and ODM work: zippers produced to a customer's specification, often under the customer's own label rather than the manufacturer's.

That model shapes the way the brand operates. Instead of marketing a distinctive house style, it competes on responsiveness, colour matching to a buyer's standard, and the ability to handle a mixed order book of metal, resin and coil articles within one production schedule.

Product range

The range covers the constructions most requested by OEM buyers:

  • Metal zippers in brass and aluminium, #3 to #8, in standard and Y-tooth profiles.
  • Moulded resin zippers in #3 to #10 for jackets, bags and sportswear.
  • Nylon coil zippers, including invisible, two-way and long-chain supply.
  • Waterproof and reflective articles for outdoor and fashion programmes.
  • Customer-branded tape, pulls and slider markings for private-label orders.

Typical applications

Dongguan's customer base spans casualwear, denim, outerwear, sportswear, bags and promotional products, and LONGDA's articles follow that mix. Typical orders include jacket and trouser zippers for export apparel programmes, bag and backpack zippers, and trim packages for private-label collections sold in Europe and North America.

Quality and compliance

Production is inspected in process and at final audit, covering slider operation, tooth strength, tape defects, colour matching and colourfastness, with strength tests referenced to ASTM D2061 and BS 3084. OEKO-TEX Standard 100 and restricted-substance documentation can be supplied for export programmes. The valid certificate for a given article is subject to the supplier's certificates.

Sourcing notes

OEM suppliers in this region usually work to a buyer's approved colour standard and provide lab dips before bulk. Minimum order quantities are quoted per article, colour and length, and are moderate for standard constructions. Sampling takes one to two weeks; bulk lead time is typically 25 to 40 days. Buyers should confirm labelling, packaging and inspection requirements at the sampling stage.
