Sock Sample Fees Explained: Mockup, Proto, PPS, Courier

Published: 2026-06-26By ZheSock TeamReading time: 6 min

Sock sample fees confuse buyers because the word sample often covers four different charges. A mockup is design work. A proto is the first knitted trial. A PPS is the final approval sample before bulk. Courier is shipping. If a supplier rolls all four into one line, you cannot compare quotes clearly or control the budget.

What counts as sock sample fees

In socks, sample fees usually mean four separate items. Ask for each one line by line.

Mockup fee. Digital artwork placed on a sock template. Typical cost is USD 10 to 25 per design for a basic crew sock layout. If artwork must be rebuilt from a low resolution image, expect USD 25 to 40.
Proto sample fee. The first real knitted sample. Typical cost is USD 35 to 60 per style for a standard cotton rich sock on 144N or 168N machines. More complex sport or terry styles often run USD 60 to 90.
PPS fee. Pre production sample made after comments are closed and before bulk starts. Typical cost is USD 20 to 40 per style if no new development is needed.
Courier. DHL, FedEx, or UPS shipping for the physical samples. One small parcel of 0.5 to 1.0 kg is often USD 30 to 65 to the US or EU. Remote area and fuel surcharges can add USD 10 to 25.

These fees are not the same. A buyer asking for one sample may actually need all four stages over 2 to 3 weeks.

For basic custom programs, bulk MOQ is often 300 to 1,200 pairs per style per color, depending on yarn, size range, and packaging. Sample fees are small compared with the bulk order value. They still matter. They set the approval process and help avoid expensive mistakes later.

Why mockup and proto fees are charged

Factories charge sample fees because development uses paid labor, yarn, and machine time. It is not just one pair of socks.

A mockup usually takes 30 to 60 minutes if the artwork file is clean. If the design needs rework for repeat size, logo position, or jacquard limits, it can take 1 to 2 hours. A technician has to fit the design to a needle layout such as 144N, 156N, 168N, or 200N. That matters. Fine text that looks clear on a screen may not knit clearly on a lower needle count.

A proto sample takes more work. A typical process looks like this.

Review tech pack and size spec. 10 to 20 minutes.
Prepare yarn and machine program. 30 to 60 minutes.
Knit 1 to 3 trial pairs to adjust tension, pattern balance, and logo shape. 30 to 90 minutes.
Toe linking or Rosso seaming, boarding, trimming, and measuring. 20 to 40 minutes.
Internal check for size, appearance, and obvious defects before shipment. 10 to 20 minutes.

That is why a plain 168N cotton crew sample might cost USD 35 to 45, while a terry sport sock with arch compression, mesh zones, and a jacquard leg logo might cost USD 65 to 90. Grip print, special yarns, or low volume dyed yarn can push development higher.

Small yarn purchases also raise cost. If a factory needs one cone of a special melange or recycled blend only for one sample, the material cost per pair is high. Some mills also have minimum dye lots, so an exact Pantone match may not be possible at proto stage without extra cost or extra lead time.

Typical price ranges by sample stage, sock type, and lead time

Here is a realistic price map for common programs. These are sample stage prices, not bulk unit prices.

Digital mockup. USD 10 to 25. Lead time 1 to 3 working days.
Basic cotton rich proto, 144N or 168N crew or ankle. USD 35 to 60. Lead time 5 to 7 working days.
Sport sock proto with terry sole, mesh, or arch support. USD 50 to 80. Lead time 7 to 10 working days.
Merino blend or recycled yarn proto. USD 60 to 90. Lead time 7 to 12 working days, mainly because yarn sourcing is slower.
PPS from a confirmed program. USD 20 to 40. Lead time 3 to 5 working days.
Courier for 1 to 6 styles in one parcel. USD 30 to 65. Transit 2 to 5 working days by express.

Needle count affects what is possible and can change sample time. 144N and 156N are common for standard casual and sport socks. 168N is common for cleaner logos and a finer hand feel. 200N is used for finer dress sock constructions. If artwork includes letters under 5 mm high, a lower needle count may not hold the detail. That often leads to one more proto round.

Lead time also depends on comment quality. If feedback says make it nicer, the process slows down. If feedback says increase cuff height from 18 cm to 20 cm, move logo 1.5 cm down, reduce foot length by 1 cm after boarding, revision can start the same day.

For standard bulk orders after approval, lead time is often 20 to 35 days for repeat styles and 30 to 45 days for new styles, subject to yarn readiness and packaging details.

What a proto and PPS should actually check

A proto sample is for structure and fit. A PPS is for final approval against the bulk standard. Many buyers treat them the same. That creates rework.

Proto checks should include:

Finished size after boarding, for example EU 39 to 42 or US men's 9 to 11.
Foot length and leg length in centimeters.
Cuff height and cuff stretch recovery.
Needle count and construction, such as 168N single cylinder crew.
Yarn composition, for example 78 percent cotton, 20 percent polyester, 2 percent elastane.
Logo readability and placement.
Terry coverage, mesh area, and any compression zone.
Toe seam type and seam comfort.

PPS checks should include:

All approved proto comments closed.
Color and yarn confirmed.
Label, header card, band roll, polybag, carton marks, and barcode confirmed if retail packed.
Bulk tolerance agreed in writing.
Inspection standard agreed, commonly AQL 2.5 for major defects and 4.0 for minor defects.

For socks, major defects usually include the wrong size range, broken yarn that affects wear, obvious pair mismatch, the wrong logo, or major stains. Minor defects might include light thread ends or small appearance issues that do not affect wear.

If you need testing, ask early. Common checks are fiber content, colorfastness to washing, colorfastness to rubbing, and dimensional stability after washing. If you need OEKO-TEX certified yarn, ask before proto. Changing from standard cotton to GOTS organic cotton or GRS recycled yarn after proto approval usually means a new sample fee and extra days.

When sample fees are refunded, credited, or not returned

There is no single rule. Refund policy depends on the supplier, the sample stage, and whether the style moves to bulk at MOQ.

Common practice looks like this.

Mockup fee. Usually not refunded. It pays for design work already done.
Proto fee. Often credited against the first bulk order if the order meets MOQ. A common threshold is 500 to 1,000 pairs per style.
PPS fee. Sometimes credited, sometimes not. Many factories treat one PPS as part of order setup only when the bulk order is confirmed.
Courier. Almost never refunded because it is a direct third party cost.

Ask exact questions before paying. Keep them blunt.

If we order 1,200 pairs in 3 colors, is one proto fee credited or all three?
If we revise the yarn after proto, does the original credit still apply?
Is the credit deducted from the deposit invoice or from the final balance?
How many sample revisions are included before a new fee starts?

Watch for vague wording like sample fee can be returned later. That means nothing unless MOQ, timing, and revision limits are written down.

A fair policy is simple. One mockup fee charged once per design. One proto fee credited when the first bulk order hits MOQ. One PPS included after deposit. Courier paid by the buyer. Not every supplier offers that. The quote should still say exactly what happens.

How to cut sample cost and avoid extra rounds

Most wasted sock sample fees come from missing specs, not from the sample charge itself. One extra proto round usually adds USD 35 to 90 and another 5 to 10 working days. It also delays bulk booking.

Send a usable tech pack from the start. It should include these points.

Size range. Example: EU 39 to 42, foot length target 24 to 26 cm after boarding.
Sock length. Example: crew, leg length 18 cm from heel top.
Needle count if known. Example: 168N for clearer logo edges.
Yarn composition. Example: 80 percent cotton, 17 percent polyester, 3 percent elastane.
Construction. Example: full terry foot, mesh on instep, arch band 2 cm wide.
Artwork in AI or vector PDF.
Pantone references or a physical color reference.
Packaging. Example: one pair with belly band, 12 pairs per inner, 120 pairs per carton.
Compliance needs. Example: OEKO-TEX yarn preferred, BSCI or Sedex audited factory required.

Be realistic about artwork. Fine serif text, thin diagonals, and photo style graphics do not translate well into knitted jacquard. If the logo height on the sock leg is only 12 mm, ask what is readable on 144N versus 168N before you order a proto.

Combine sample shipments. Sending 4 styles in one parcel often costs only USD 5 to 15 more than sending 1 style alone. If you have your own DHL, FedEx, or UPS account, use it. That removes markups and gives you direct tracking.

Ask for photos with a ruler before courier pickup. A quick measurement photo can catch obvious size errors and save one shipment. It is simple. It works.

Frequently Asked Questions

Are sock sample fees normal, or should good factories make them free?

Sock sample fees are normal. A real proto uses machine setup, yarn, labor, finishing, and shipping. Some suppliers credit one proto fee back after a bulk order reaches MOQ, often 500 to 1,000 pairs per style. Free samples are not standard, and the cost is often added back into the unit price later.

What is the difference between a sock proto and a PPS?

A proto is the first knitted trial used to check fit, construction, yarn choice, and logo execution. A PPS is the final pre production sample made to the confirmed specification before bulk starts. The PPS should match the approved size, colors, packaging, and workmanship standard used for production release.

How many sample rounds are normal before bulk?

For a standard custom style, one mockup, one proto, and one PPS is normal. Two proto rounds are common if logo detail, fit, or yarn needs adjustment. More than two proto rounds usually means the brief was incomplete or the design kept changing. Each extra proto round often adds 5 to 10 working days and USD 35 to 90.

Can courier cost on sock samples be reduced?

Yes. Combine several styles into one parcel, use your own DHL, FedEx, or UPS account, and avoid shipping single pairs one by one. A 0.5 to 1.0 kg express parcel is often USD 30 to 65, so sending 4 to 6 styles together cuts the cost per style a lot.

Does sock complexity change sample fees?

Yes. A plain cotton rich 168N crew sample may cost USD 35 to 45. A terry sport sock with mesh zones, arch support, a jacquard logo, or grip print may cost USD 60 to 90. Special yarns such as merino blends, GOTS organic cotton, or GRS recycled yarn can add cost and time because sourcing is slower and small lots cost more.
