Custom Machine Cover Wholesale Price Guide: What Drives Cost at the Factory Gate

Two quotes landed on my desk last Tuesday — both for a 600D Oxford outdoor equipment cover, same dimensions, same quantity. One was $8.20 per unit FOB Ningbo. The other was $5.80. The buyer had already decided the $5.80 quote was the winner. I told him to slow down.

I pulled the two spec sheets side by side. The $5.80 quote specified nylon thread with no UV inhibitor, single-stitch hems with 2.5 stitches per cm, and a 210D liner instead of 420D. The $8.20 quote specified bonded polyester thread with UV stabilizer, double-stitch hems at 3.5 stitches per cm, and a 420D PU-coated liner. These are not the same cover. They cost different amounts to make because they contain different amounts of material and labor — about $2.40 worth, to be exact.

This is the problem with custom machine cover wholesale price comparison: buyers compare final numbers without comparing the cost drivers underneath. This guide breaks down those drivers so you can read a quote and know what you're actually paying for.

The Cost Pyramid: Where Your Money Goes

A custom machine cover's factory-gate price is built from five layers. Each layer has a range, and the width of that range is what separates a $5 cover from a $15 cover — even when both use the same fabric on the spec sheet.

The layers stack like this, from bottom to top:

Fabric dominates. On a cover that uses 4 to 6 linear metres of material, a $1.00 difference in per-metre fabric cost translates to $4 to $6 per cover at the factory gate. That's before labor, hardware, or margin. If the fabric spec is not nailed down in writing, the factory has a $6 per unit incentive to use the cheaper fabric.

The second-largest variance is in construction details — things that are invisible on a sample photo but determine whether the cover lasts one season or five. We'll get to those. For the full picture on how specs translate to field performance, see our industrial machine cover OEM guide.

Material Tiers and Their Price Implications

The fabric is not one variable. It is three variables that multiply: base fabric density, coating type, and coating application weight. Here is how they break down at current factory-gate rates for 600-unit orders:

The jump from 600D Oxford with PU coating to TPU laminate costs about $1.00 to $1.20 more per metre. On a cover using 5 metres of fabric, that's a $5 to $6 difference in material alone. But in a coastal environment with salt spray and 2,000+ hours of annual sunshine, the TPU cover will outlast the PU cover by 12 to 18 months. The material premium pays for itself in warranty reduction.

Thread matters more than most buyers realize. Bonded polyester with UV stabilizer costs the factory about $0.12 to $0.18 more per cover than standard nylon. Nylon absorbs moisture, swells, and degrades faster under UV. In an industrial environment with coolant mist or washdown, nylon thread fails in roughly half the time of bonded polyester. A $0.15 saving on thread can generate $3.00 in warranty claims per cover. For a detailed look at how fabric choices affect durability across applications, read our Oxford fabric guide.

Construction Details: Labor Costs That Separate Quotes

A sewing machine operator in Ningbo costs the factory about $3.50 to $4.50 per hour including social insurance. A standard medium machine cover takes roughly 18 to 25 minutes of sewing time. That puts base labor at roughly $1.30 to $1.90 per cover before any of the construction variables that follow.

Stitch density. Moving from 2.5 stitches per cm to 3.5 stitches per cm adds about 40 percent more thread consumption and roughly 8 to 10 seconds per linear metre of seam. On a cover with 12 metres of total seam length, that's an extra 2 minutes of sewing time and about $0.25 in additional thread. The result: a seam that will not pull apart when someone yanks the cover over a machine corner.

Reinforcement patches. Every hardware attachment point — zipper end, buckle base, D-ring, Velcro strip — concentrates load on a small area of fabric. Without a reinforcement patch, the hardware pulls out under repeated use. A reinforcement patch adds about 30 seconds of sewing time per attachment. On a cover with six attachment points, that's 3 minutes of labor — about $0.18 per cover at factory rates. Factories that quote cheaper prices often skip reinforcement. The covers look the same in the shipping sample. They fail differently.

Bottom hem construction. The bottom edge of an outdoor cover sits in water — rain pooling, snow melt, morning dew. A single-fold hem with one stitch line wicks moisture into the fabric. A double-fold hem with thermal sealing or a welded edge prevents water ingress. The welded hem adds about $0.20 to $0.30 per cover in equipment amortization and labor. It eliminates the most common failure mode in wet climates.

Ventilation. A cover that seals completely traps condensation. Moisture sits against the machine surface, accelerates corrosion, and defeats the purpose of the cover. Proper ventilation uses offset vents — one low, one high on the opposite side — creating convection that moves air through without letting rain in. Vents with mesh backing and rain hoods add about $3 to $4 per cover in materials and labor. It is the first feature that disappears when a factory is trying to hit a target price.

Quantity Levers: MOQ, Volume Breaks, and Setup Amortization

A pattern costs roughly $300 to $500 to develop. A cutting die for high-volume runs costs $200 to $400. A logo screen costs $60 to $80 per color. These setup costs are fixed — they do not change whether you order 100 covers or 1,000. Where they land matters enormously.

The sweet spot for most B2B buyers is 500 to 800 units per design. Below 300, the setup cost dominates — a $300 pattern fee divided by 100 units is $3.00 per cover that disappears at 500 units. Above 1,000, the additional savings per unit shrink while inventory carrying cost rises.

The MOQ trap. A factory quotes "MOQ: 300 units." You assume that means 300 covers total. The factory means 300 covers per SKU — each size, each color counts separately. Three sizes in two colors is six SKUs. That's 1,800 units, not 300. Always confirm: "Is MOQ per design, or per SKU?" The answer can triple your landed cost.

Hidden Costs: What the Unit Price Doesn't Include

The FOB unit price is the starting point. Everything between the factory gate and your warehouse adds cost. Some of it is predictable. Some of it blindsides first-time buyers.

Sample and prototype fees. A pre-production sample costs $150 to $400 depending on complexity. Some factories credit this against the production order. Some don't. Confirm before you authorize the sample. If the factory requires three iterations before approval — and complex covers often do — sample costs alone can hit $1,000 before a single production unit is cut.

Sea freight and inland logistics. A 40-foot container from Ningbo to Rotterdam costs roughly $3,500 to $5,500 at current rates. From Ningbo to Los Angeles: $2,800 to $4,200. Inland trucking from factory to port adds $200 to $500. Destination port charges — terminal handling, customs clearance, onward trucking — add another $800 to $1,500. All in, logistics adds $0.60 to $1.80 per cover depending on container utilization and destination.

Duties and tariffs. Protective covers typically fall under HS code 6307.90 — made-up textile articles. EU import duty is 6.3 to 12 percent depending on material classification and country of origin. US Section 301 tariffs on Chinese textile products add 7.5 to 25 percent depending on the specific subheading. Check with a customs broker before you commit to a volume. A 25 percent tariff on a $12 cover turns it into $15 at the border — before inland distribution.

Palletizing and fumigation. Wood pallets require ISPM 15 heat treatment and fumigation certification for international shipping. Some ports require plastic pallets instead of wood. Palletizing and fumigation adds $120 to $200 per pallet. A container with 22 pallets adds $2,600 to $4,400. If your quote says "FOB" without specifying palletizing, the cost is likely not included.
