Import-Ready Spec Sheet for Custom Metal Giveaways

1. Define Product, Market and Compliance Before Quoting

Do not brief a supplier with only “custom pin” or “metal keychain.” That wording lets the factory choose any construction that resembles the artwork at the lowest cost. Start with product family, destination market, user age group, handling intensity and packing format. A 3,000-piece enamel conference pin for Germany has different nickel, labeling and carton requirements than a 20,000-piece retail keychain for the United States, even if the front logo is identical.

Use one precise opening line: “Soft enamel lapel pin, 30 mm wide, adult event giveaway, EU market, one butterfly clutch, individual OPP bag, nickel-free finish required.” For retail, write: “Zinc alloy keychain, 45 mm body, US souvenir channel, daily handling, 30 mm split ring plus swivel connector, printed retail card with UPC and OPP bag.” That single line affects base metal, plating thickness, attachment strength, warning labels, inspection criteria and landed cost.

Classify the item as disposable event merchandise, retail merchandise, uniform badge, collectible coin, fridge magnet or functional keyholder. Iron soft enamel is usually adequate for a three-day event pin. A daily-use keychain should use zinc alloy, brass or stainless hardware, heavier plating and stronger connectors. Child-targeted items need a stricter review for small parts, sharp edges, accessible magnets and applicable market rules. If the use case is missing, the quote may look attractive while the importer absorbs the failure risk.

2. Dimensions, Thickness, Weight and Tolerances

Specify maximum width by maximum height in millimeters, not only inches. Common enamel pin widths are 20 to 35 mm. Challenge coins often use 38.1 mm, 44.45 mm or 50.8 mm diameters. Metal keychain bodies usually run 35 to 60 mm. Fridge magnets commonly sit between 40 and 70 mm, with the practical limit controlled by magnet pull force, carton weight and air freight cost.

Write thickness as a nominal value with tolerance. Soft enamel pins are usually 1.2 to 1.6 mm in iron or brass. Hard enamel pins are commonly 1.5 to 1.8 mm because the surface is polished flat after color filling. Challenge coins normally run 2.5 to 4.0 mm. Zinc alloy keychain bodies are often 2.0 to 3.5 mm. Practical production tolerances are +/-0.2 mm for die-struck pins, +/-0.25 mm for coins and +/-0.3 mm for cast zinc alloy bodies unless the part must fit a capsule, opener insert or magnetic base.

Add target unit weight where postage, retail feel or carton handling matters. A 30 mm pin is commonly 8 to 12 g before packing. A 45 mm zinc alloy keychain may be 25 to 45 g. A 50.8 mm coin at 3.5 mm thickness can exceed 40 g before capsule, pouch or box. Heavier metal improves perceived value, but it increases material cost, carton gross weight and air freight charges.

Product	Normal size range	Typical thickness	Practical tolerance
Soft enamel pin	20 to 35 mm	1.2 to 1.6 mm	+/-0.2 mm size, +/-0.1 mm thickness
Hard enamel pin	20 to 35 mm	1.5 to 1.8 mm	+/-0.2 mm size, +/-0.1 mm thickness
Challenge coin	38.1 to 50.8 mm	2.5 to 4.0 mm	+/-0.25 mm diameter, +/-0.15 mm thickness
Zinc alloy keychain	35 to 60 mm	2.0 to 3.5 mm	+/-0.3 mm size, +/-0.15 mm thickness
Metal fridge magnet	40 to 70 mm	1.5 to 3.0 mm body	+/-0.3 mm size, magnet pull tested

3. Material, Process, MOQ and 2026 FOB Cost Bands

State base metal and process together. Iron die-struck soft enamel is cost-effective for flat pins with clean color blocks. Brass or copper is preferred for hard enamel polishing, sharper fine detail and premium uniform badges. Zinc alloy casting suits 3D relief, cutouts, irregular keychains and thick souvenir shapes. Stainless steel improves corrosion resistance for bottle openers and tools, but it limits some enamel and plating options and is less economical for sculpted promotional shapes.

For 2026 China FOB planning at 1,000 pieces, normal ranges are USD 0.35 to 0.85 for 25 to 30 mm soft enamel pins, USD 0.65 to 1.35 for hard enamel pins, USD 1.20 to 3.50 for 45 mm zinc alloy keychains and USD 1.80 to 5.50 for 45 to 50 mm challenge coins. Tooling is usually separate: USD 35 to 90 for a simple pin mold, USD 60 to 160 for a keychain mold and USD 90 to 250 for larger coins or 3D relief. Dual plating, epoxy, laser engraving, sequential numbering, retail cards, individual barcodes and low MOQs can move pricing outside these bands.

MOQ is process-dependent. Many factories accept enamel pin orders from 100 pieces, but pricing below 300 pieces is usually inefficient because tooling, color setup and plating line handling are fixed. Use MOQ tiers of 100 for samples or VIP batches, 300 to 500 for small campaigns, 1,000 to 3,000 for normal promotional buying and 5,000+ for distributor margin planning. Ask every supplier to quote 300, 500, 1,000 and 3,000 pieces with the same packing so cost breaks are visible.

Add a tooling ownership line: “Tooling paid by buyer, retained by factory for 24 months after last shipment, no mold charge for exact reorder unless mold is damaged, expired or design changes.” Without this line, a reorder can be treated as a new project.

4. Artwork, Pantone Control and Manufacturable Detail

The artwork section should state file format and physical limits. Vector AI, PDF, EPS or SVG is preferred, with text converted to outlines and Pantone Solid Coated references for enamel or print colors. For enamel pins, raised metal lines should be at least 0.25 mm wide, recessed enamel channels at least 0.30 mm wide and isolated enamel islands at least 0.50 mm unless the factory confirms the mold can hold the detail. Text below 1.5 mm high is high risk; below 1.2 mm it is usually not reliable in enamel.

Color tolerance must match the process. Enamel should be judged against the approved pre-production sample under D65 light or consistent daylight-equivalent lighting, not against a coated paper chip alone. Enamel paste, curing temperature, polishing and adjacent metal borders all affect perceived color. Printed backing cards can usually be controlled more tightly than enamel. Antique plating, sublimated fabric and translucent fills should not be expected to match coated paper exactly.

Require factory production artwork before tooling. The proof should show actual metal lines, enamel areas, cutouts, backstamp, plating, attachment position and size callouts. Buyer artwork often includes gradients, hairlines, soft shadows or reversed text that cannot be made as drawn. Decide whether those elements become screen print, offset print plus epoxy, simplified enamel or removed detail before the mold is cut.

• Confirm maximum width and height in millimeters on the proof.
• Check every Pantone number against the current brand guide.
• Flag text under 1.5 mm high before tooling starts.
• Define gradients as offset print plus epoxy, screen print, simplified enamel or not allowed.
• Approve the back view, including logo stamp, year mark, post location, legal text and country-of-origin marking if required.

5. Plating, Epoxy and Surface Durability

Specify plating by finish, target thickness and use expectation. Common finishes are nickel, imitation gold, rose gold, black nickel, antique brass and antique silver. A typical decorative plating build is 3 to 5 microns for event pins. Daily-use keychains should target 5 to 8 microns where geometry and cost allow. For nickel-sensitive markets, write “nickel-free finish required” and confirm the compliance standard before sampling. Standard nickel plating should not be assumed acceptable for EU skin-contact products.

Gold wording needs precision. “Gold plated” may mean imitation gold tone, bright gold, antique gold or real gold flash. Real gold increases cost and still needs a thickness target, such as 0.03 to 0.05 microns for flash over a decorative base. Black nickel and dyed black finishes show edge scratches clearly, especially on raised corners of keychains, bottle openers and coins. Antique finishes vary because recess darkening depends on relief depth and hand wiping.

Epoxy protects soft enamel and printed surfaces, but it changes the product. A common dome is 0.4 to 0.8 mm thick. It adds gloss, creates glare in retail photography and softens fine surface detail. Do not specify epoxy for designs that depend on crisp antique relief, matte texture or a flat collectible coin surface.

Spec wording	Best use	Risk to control
Nickel-free silver finish, 3 to 5 microns	EU event pins and badges	Confirm test requirement before production
Imitation gold, 3 to 5 microns	Short-term promotional pins	Color can shift between batches without sample control
Black nickel, 3 to 5 microns	Modern badges and dark logos	Raised edges scratch more visibly
Antique brass or antique silver	Coins and 3D relief designs	Hand-wiped recess tone varies by relief depth
Clear epoxy dome, 0.4 to 0.8 mm	Printed keychains and soft enamel protection	Adds gloss and reduces sharp surface feel

6. Attachments, Hardware and Functional Tests

Attachments cause many avoidable failures: pin posts rotate, magnets slide, split rings open, brooches sag and clips break. Specify attachments as measured components. For lapel pins, state butterfly clutch, rubber clutch, deluxe clutch, safety pin, brooch pin or magnet, including quantity and placement. A 30 mm pin usually needs one post. Long horizontal badges above 35 to 40 mm often need two posts to prevent rotation.

For keychains, specify ring diameter, wire diameter and connector style. A normal split ring is 25 to 30 mm outer diameter with 1.5 to 2.0 mm wire. A heavier zinc alloy body should use a reinforced jump ring, swivel connector or chain link sized to the part weight. For magnets, specify magnet type, size and pull test on a painted steel plate. A 10 mm magnet may hold a thin pin but fail on a thick zinc alloy magnet body.

Put simple factory-floor tests into the sheet. Pin posts should survive a 90-degree bend check on representative samples without immediate detachment. Split rings should not permanently deform during normal key insertion. Magnets should hold the finished item vertically on a clean painted steel surface for at least 60 seconds. These checks do not replace laboratory testing, but they catch weak soldering, undersized magnets and soft hardware before shipment.

7. Sampling, Lead Time, AQL and Export Packing

Separate sample lead time, buyer approval time and mass production lead time. A custom metal sample normally takes 7 to 12 days after artwork approval and mold payment. Mass production is commonly 12 to 25 days after sample approval for 500 to 5,000 pieces, and 25 to 40 days for larger or more complex orders. Air freight is often 4 to 8 days after dispatch. Sea freight plus destination handling can take 25 to 45 days depending on port, route and season.

Any change after sample approval can reset the schedule. Changes to size, attachment, plating, enamel color, backstamp or packaging can add 3 to 10 days because the factory may need revised tooling, new plating samples or a new packing method. For seasonal campaigns, place the PO at least 45 to 60 days before the required in-hand date if using air freight, and 75 to 100 days if using sea freight.

Inspection belongs in the spec sheet. For most custom pins, coins and keychains, ANSI/ASQ Z1.4 general inspection level II with AQL critical 0, major 2.5 and minor 4.0 is a practical starting point. Critical defects include sharp burrs, unsafe loose parts on child-targeted items, wrong logo, wrong plating and contaminated packaging. Major defects include missing color, visible enamel overflow, weak attachment, heavy scratches, plating stains and wrong packing. Minor defects include small cosmetic variation outside the approved sample that does not affect use.

Packing should define unit pack, inner pack and export carton. A standard pin can be packed one piece per OPP bag or on a backing card, then 50 to 100 pieces per inner bag or box. Keep export cartons under 12 to 15 kg for pins and under 10 to 12 kg for coins and heavy keychains. Use dividers, tissue or layered packing if polished plating may scratch. Carton marks should include item number, description, quantity, gross weight, net weight, carton size, carton count and country of origin where required.

• Set AQL and defect definitions before production starts.
• Define the approved pre-production sample as the inspection reference.
• Keep export cartons under the agreed maximum gross weight.
• Request carton photos and random finished-goods photos before balance payment.
• Confirm invoice description, HS code suggestion and packing list match the customs entry plan.

8. Final PO Check Before Mold Cutting

Before issuing the purchase order, convert the sales conversation into a one-page spec sheet with numbered lines: product, market, dimensions, thickness, weight target, material, process, plating, colors, attachment, packaging, AQL, lead time, shipping term and documents. Attach the approved production proof and state that mass production must match the approved sample within written tolerances.

Do not compare FOB quotes until every supplier is quoting the same construction. A quote that excludes tooling, uses 3 microns of plating instead of 5, changes brass to iron, removes epoxy or switches retail cards to bulk packing is not the same product. Ask each factory to list mold cost, sample cost, unit price, packing cost, estimated carton weight and MOQ price breaks separately.

A strong spec sheet does not need to be long. It needs to make every requirement testable, quotable and visible before the mold is cut. The highest-risk lines are usually metal choice, attachment strength, artwork below manufacturing limits, unrealistic Pantone matching, under-specified plating and cartons that are too heavy for normal handling. Fix those lines before sampling, not after finished goods are packed.
