Leather Jacket Hardware and Zips: What Brands Should Specify

Nov 3

6 min read

Updated: 23 hours ago

Leather jacket hardware covers every zip, snap, buckle, rivet and puller on the garment, and brands should specify each one in the tech pack: type, size, length per size, finish, branding and placement. For jackets sold in the EU or UK, metal parts in prolonged skin contact must also meet the REACH nickel-release limit of 0.5 µg/cm²/week.

Key Takeaways

Updated November 2026: REACH Annex XVII entry 27 limits nickel release to below 0.5 µg/cm²/week for zippers, rivets, rivet buttons and other metal parts of garments in direct and prolonged skin contact.
The EU reference test method for nickel release is EN 1811:2023, listed by the European Commission on 20 December 2023.
Zip type, tooth size, length per size, slider style and finish colour should be written into the tech pack for every zip on the jacket.
Hardware finish (antique brass, gunmetal, black, silver tone) should be approved on a physical swatch before bulk, and matched across zips, snaps and buckles.
Sanwas International produces private label and OEM leather jackets with MOQs under 500 units per style, a complimentary first sample and AQL inspection before dispatch.

What hardware goes on a leather jacket?

A typical leather jacket carries four to six hardware families, and each one needs its own line in the bill of materials. Missing a single line, such as the sleeve-zip length or the snap finish, is one of the most common reasons a first sample comes back wrong.

Component	Common options	What to specify
Front zip	Metal teeth, moulded plastic teeth, nylon coil; open-end (separating), two-way open-end	Tooth size, length per size, slider and puller, finish, left/right insertion
Pocket and sleeve zips	Closed-end metal or coil zips	Length, tooth size, whether exposed or concealed, puller style
Snaps and press studs	Ring snaps, spring snaps, cap snaps	Diameter, cap finish, engraved logo or plain, backing for thin leather
Buckles and belts	Roller, centre-bar or slide buckles; D-rings	Inner width matched to belt width, finish, attachment method
Rivets and eyelets	Double-cap rivets, eyelets with washers	Size, finish, placement on drawing
Branded trims	Engraved pullers, metal plates, embossed snaps	Artwork file, finish, approval sample, extra lead time

Which zip suits which leather jacket style?

Match the zip to the weight of the leather and the way the jacket is worn: heavier leathers and biker styles take heavier metal zips, while soft lambskin and bomber styles can use lighter metal or coil zips. Long styles such as car coats benefit from a two-way open-end zip so the wearer can open the hem when seated.

Jacket style	Typical front closure	Notes for the tech pack
Biker / motorcycle	Heavy metal open-end zip, often asymmetric	Specify sleeve-cuff zips, pocket zips and belt buckle finish together
Bomber	Mid-weight metal or coil open-end zip	Check zip length against rib-knit waistband height
Trucker	Snaps or shank buttons	Snap diameter and cap finish; reinforcement behind leather
Blazer	Buttons, rarely zips	Button size, shank or sew-through, horn or metal
Car coat / trench	Two-way open-end zip or buttons, belt with buckle	Two-way slider, buckle inner width, belt keeper placement

Do leather jacket zips and snaps need to be nickel-safe for the EU and UK?

Yes. Under REACH Annex XVII entry 27, metal parts of garments intended for direct and prolonged skin contact, including rivet buttons, tighteners, rivets, zippers and metal marks, must release less than 0.5 µg/cm²/week of nickel (as of November 2026).

ECHA's guidance on the restriction describes prolonged contact as skin contact of potentially more than 10 minutes on three or more occasions within two weeks, or 30 minutes on one or more occasions within two weeks (ECHA, nickel restriction document). Collar snaps, cuff zips and waist buckles on a leather jacket can easily meet that threshold.

Compliance is normally shown with a test report to the EU reference method. In December 2023 the European Commission listed EN 1811:2023 as the reference standard for nickel release, replacing EN 1811:2011+A1:2015 (UL Solutions summary). UK REACH retained the Annex XVII restrictions that applied at the end of 2020, so UK importers should ask for the same evidence.

Ask whether the hardware is sourced as nickel-free or nickel-release compliant, and request the supplier's test report.
Keep reports on file per hardware lot and per finish colour, because plating changes between finishes.
If you sell in several markets, list the destination markets on the purchase order so the factory sources to the strictest requirement.

How should brands choose and approve hardware finish?

Pick the finish first from the jacket's mood, then lock it on a physical swatch card before bulk. Antique brass and gunmetal suit vintage biker and car-coat styles; silver tone and matte black suit minimal and contemporary styles.

Plating colour can vary between hardware lots and between component types, so a zip slider, a snap cap and a buckle in the same named finish may not match. Approve them side by side on the leather colour you are using, and keep one approved set as the bulk reference. If you need custom engraved pullers or logo snaps, add the artwork approval and tooling time to your critical path, since branded trims usually take longer than stock hardware.

What should a leather jacket hardware spec in the tech pack include?

A complete hardware spec lets any factory quote and sample accurately the first time. Use this order for every component:

Component name and position on the technical drawing (e.g. front zip, left chest pocket zip, cuff snap).
Type and size (e.g. metal open-end zip, tooth size; ring snap, cap diameter).
Length per size in your size range, especially for front and sleeve zips.
Slider and puller style, including locking or non-locking slider.
Finish name and approved swatch reference.
Branding: plain, engraved or embossed, with artwork file.
Compliance: destination markets and required test reports (e.g. nickel release for EU/UK).
Sourcing: brand-nominated supplier or factory-sourced to your specification.

Zip lengths should follow your graded size chart; our leather jacket size grading guide for UK, EU and US explains how measurements change across sizes.

Frequently Asked Questions

What nickel limit applies to zips on leather jackets sold in the EU?

REACH Annex XVII entry 27 requires metal parts of garments in direct and prolonged skin contact, including zippers, rivets and rivet buttons, to release less than 0.5 µg/cm²/week of nickel. The EU reference test method is EN 1811:2023. UK REACH retained the same restriction.

Which zip should I use on a leather biker jacket for my brand?

Biker jackets usually take a heavy metal open-end front zip, often asymmetric, with matching metal zips on pockets and cuffs. Specify tooth size, length per size, slider style and finish in the tech pack so every zip on the jacket matches.

Can an Indian factory source branded zip pullers and logo snaps for my private label jackets?

Yes. Supply the artwork, finish and placement, and approve a branded trim sample before bulk. Branded hardware usually adds lead time compared with stock hardware, so build that into your production calendar.

Should hardware finish be approved before bulk production of leather jackets?

Yes. Approve zips, snaps and buckles side by side on a physical swatch in the final leather colour, because plating can vary between lots and component types. Keep the approved set as the reference for bulk inspection.

What is the MOQ for private label leather jackets at Sanwas International?

Sanwas International accepts orders under 500 units per style. The first sample is complimentary, sampling starts from 72 hours, bulk lead times start from 30 days, and orders are AQL-inspected before export shipping.
