The alpaca premium is priced by the maker, not by the fibre

The numbers behind this

A pair of quotes for a Peruvian alpaca sweater sits on a desk, a long way apart on price. The buyer reading them assumes the difference is in the yarn. The shipping record says otherwise, and what it says changes how any alpaca quote should be read.

Here are two facts about that market. Both are solid, and they do not sit comfortably next to each other.

Two facts that do not fit together

The first is the one the trade runs on. An alpaca sweater leaves Peru at $48.76 a piece. A cotton sweater leaves at $21.93. Alpaca is a scarce fibre off a slow animal, so a gap that size reads as the fibre doing its job.

The second fact is stranger.

Take only cotton sweaters, the plain and abundant thing. Split the companies into those who also work alpaca and those who never do. The first group sells its cotton at $46.52. The second sells its cotton at $15.55.

Part of that distance is weight, because the alpaca companies knit heavier cotton as well. Compare only garments in the same weight band and the gap settles at more than double. Pricing both sides by the kilo lands in the same place. Still more than double, with no alpaca on either side of the comparison.

A week spent trying to break it

Both cannot be a story about fibre, so I spent a week trying to break the second one.

The first suspect was the comparison itself. It survived on cardigans. It survived on shipments going only to the United States, where it came out at 2.4. It survived in every year I checked. It survived when I raised the bar to alpaca declared at full content, and again when I removed the largest alpaca company in the country.

Then I checked whether the two groups were shipping different garments under the same word. Their cotton sweaters sit within 50 grams of each other.

So I turned on the first fact instead, and that is where it gave way.

Inside one company the famous gap almost closes

Nearly 80 companies ship both alpaca and cotton. Measured against itself, the median company sells its alpaca at about 1.15 times its own cotton.

Inside a company, in other words, the famous gap almost closes. What the market average is really measuring is which companies happen to ship alpaca and which happen to ship cotton.

My own next guess was scale, the small studio against the industrial plant. Sorting the companies from smallest to largest barely moves the price, so that one died too.

What is left is the maker. Call it the Maker Premium. The price attaches to the company, and the company carries it across whatever fibre it is knitting that season. The alpaca company's cotton is expensive because it is that company's cotton.

The adjectives on the label move very little

The fibre content says the same thing from the other side, and this is where a buyer usually loses money. Inside a single company, baby alpaca and plain alpaca at equal declared content come out at 1.01. The blends land within a tenth of the pure article. The single largest alpaca product Peru ships is a blend of 65% alpaca and 35% nylon, and it prices in line with everything else.

Which is worth sitting with. Every lever the fibre offers moves the price by a few percent inside the company that makes it. Changing the company moves it by a factor of three.

Two limits, because they matter

The first is that this lives in sweaters and cardigans. It stops at the sweatshirt rack, where only seven of the alpaca companies ship cotton in any volume and the gap is gone. That lane is industrial athleisure and it prices like it.

The second is that the gap narrows as the market contracts. The first half of 2026 ran about a quarter below 2024. A slowdown reaches the expensive end of a market first.

For a buyer the practical move is small and slightly rude. Ask any Peruvian company quoting you alpaca what they charge for a plain cotton sweater. That answer sorts the makers before a single gram of fibre is discussed, and it is the one figure a company has no reason to dress up, because they think you are asking about something else.

Common questions

Does alpaca always cost more than cotton in Peru?

Across the market yes, at $48.76 against $21.93. Inside a single company the median gap falls to about 1.15 times, so the market average is mostly measuring which companies ship which fibre.

Why is a cotton sweater from an alpaca company so expensive?

Because the price attaches to the maker. Companies that also work alpaca sell their cotton at $46.52 against $15.55 for companies that never do, and the gap survives when you compare only garments in the same weight band.

Does more alpaca content mean a higher price?

Barely. Inside the same company a sweater of 50 to 69% alpaca sells at 0.92 of that company pure alpaca, and the largest alpaca product Peru ships is a 65% blend that prices in line with everything else.

Is baby alpaca worth more than plain alpaca?

At equal declared content and inside the same company it comes out at 1.01 across 43 exporters.

How can a buyer sort Peruvian makers quickly?

Ask any company quoting alpaca what they charge for a plain cotton sweater. It is the one figure they have no reason to dress up, because they think you are asking about something else.
