Who this checklist is for

If you're the one who actually places the eyeliner order—not the one picking shades on a mood board, but the one chasing POs, QC reports, and invoices—this checklist is for you. I've been coordinating eyeliner sourcing for a mid-size beauty brand since 2021. I handle roughly $400k a year across 7 suppliers, mostly pencil eyeliner, kajal eyeliner, and waterline eyeliner formats, plus the occasional winged eyeliner launch. I report to both product development and finance, which means I hear about it from both sides when something goes wrong.

Below are the 7 steps I run before any new OEM order. Some are obvious. A couple aren't, and those are the ones that have actually saved me from bad batches. I've tried to keep each step concrete enough that you can copy it into your own process.

Step 1: Nail down the format before you talk price

Pencil eyeliner, kajal eyeliner, waterline eyeliner, and winged eyeliner are not interchangeable—not for the buyer, and definitely not for the factory. A waterline formula needs to be a lot gentler because it goes on the inner rim. Kajal is typically softer and smudgier. A brown eyeliner pencil and a brown liquid liner can use completely different pigment systems.

Before I ask for quotes, I write out: format (pencil, kajal, liquid, gel), application zone (waterline, lash line, wing), finish (matte, satin, shimmer), and whether it needs to be sharpenable or retractable. If I skip this step, I end up comparing quotes for two different products and wasting everyone's week. Fixing the spec sheet first is a no-brainer, but I've watched people skip it because they were in a hurry.

Step 2: Lock the shade story early

Brown eyeliner is where I see the most back-and-forth. "Brown" can mean anything from a warm chocolate to a cool taupe to something that pulls almost grey on certain skin tones. I ask the supplier to match against a physical swatch or a Pantone reference—not a photo. Photos lie under different lighting, and I've approved shades from a screen that arrived looking completely different on an actual eyelid.

From the outside, a shade match looks simple. The reality is that pigment systems behave differently across eyeliner styles, and a "close enough" match reads as a QC fail at scale. If we're launching a brown pencil and a kajal together, I don't assume the factory can use the same pigment base. I ask them to confirm.

Step 3: Verify claims and compliance before samples

This is the step most people skip, and it's the one that matters most if you're selling in the US. Per FTC advertising guidelines (ftc.gov), any claim on the packaging—"smudge-proof," "waterproof," "24-hour wear," "ophthalmologist-tested"—has to be truthful and substantiated with evidence. If your supplier can't document the testing behind a claim, don't print it.

I'm not a regulatory expert, so take this with a grain of salt, but in my experience the safe move is to only claim what the supplier's test reports actually cover. I've seen brands get dinged for putting "all-day wear" on a pencil liner that started fading before lunch. It's a red flag if a supplier offers to "just add" claims to the artwork without test docs. That conversation usually means they're hoping you won't ask again.

Step 4: Order samples and test them like a customer

Samples are where cheap sourcing gets exposed. I ask for at least 3 units per shade per format, and I test them for a week on real people—not just swatched on paper. For waterline eyeliner, that means actually wearing it on the waterline and checking for irritation. For kajal, it means checking how it smudges after 4 hours. For winged eyeliner, it means seeing if the tip holds a sharp line or drags halfway through.

I learned never to assume a sample represents the production batch after a "budget vendor" shipped pencils that looked nothing like what we'd approved. The pigment was grainy and the barrel cracked on 2 out of 10 units. Reprinting cost more than the original "expensive" quote would have. Net loss: somewhere around $1,800 plus a delayed launch. The 'cheaper option' looked smart until we unboxed it. Now I verify sample-to-production consistency before I sign anything.

Step 5: Confirm MOQ, lead time, and packaging in writing

MOQ varies a lot by format. Pencil eyeliner with a custom barrel might start at 3,000–5,000 units. Stock kajal might start at 1,000. I always get these numbers in writing, along with lead time from PO to ship date, and I factor in a buffer because shipping is unpredictable and I'd rather quote a long timeline than look bad to my VP when containers slip.

Packaging is its own trap. Custom boxes, inserts, shrink wrap, barcodes—each one adds a week or two and often a setup fee. I ask the supplier to quote packaging separately so I can see what's actually driving the cost. If everything is bundled into one number, I can't tell whether I'm paying for the eyeliner or the box. That's usually a sign I need a cleaner quote.

Step 6: Check invoicing, terms, and shipping before you commit

This is the boring step that finance will thank you for. I verify the supplier can issue a proper commercial invoice, packing list, and certificate of origin. If we're importing, I confirm HS codes and duty estimates before the order goes out—not after. I've watched a shipment sit in customs for two weeks because the invoice described the product too vaguely. When I took over purchasing in 2021, I didn't know this mattered. Now I do.

Payment terms matter too. 30/70 or net 30 with a deposit is normal for OEM. Full payment upfront from a new supplier is a deal-breaker for me unless the amount is small enough to walk away from. That's not a hard rule, but it's a pretty reliable red flag.

Step 7: Run a small pilot order first

Even after all six steps, I don't jump straight to a full container. I place a pilot order—usually the MOQ or less—and put it through the full process: production, QC, shipping, invoicing, and a spot check at the warehouse. If the pilot goes smoothly, the next order can scale. If it doesn't, I've risked a small amount instead of a full season's budget.

Bottom line: a pilot order costs a bit more per unit, but it's way cheaper than redoing a launch. And honestly, it's a lot less stressful, too.

Common mistakes to avoid

  • Comparing quotes from suppliers who quoted different specs. Fix the spec sheet first, then quote.
  • Skipping the compliance review because the supplier "seems reputable." FTC guidance doesn't care how nice the sales rep was.
  • Assuming brown eyeliner shades are universal. They're not—confirm against a physical reference.
  • Forgetting to ask who owns the tooling if a custom barrel is involved. If the relationship ends, you don't want to lose the mold.
  • Treating lead time as fixed. Build in a buffer, especially for waterline eyeliner and kajal formats that may need extra stability testing.

None of this is complicated. It's just a lot of small checks that add up. The procurement people who get burned are usually the ones who skip one step because they're in a hurry—and then spend three weeks cleaning it up. If you run all 7 every time, even on products you've ordered before, you start to catch the little inconsistencies early. That's the whole point.
