A 2-head semi-automatic filling scale from Chinese OEMs was listed on Made-in-China.com in 183,096 packing-machine SKUs as of 2025-05-13, with CE, GMP and ISO 14001 / ISO 45001:2018 commonly co-declared on the same SKU [S4]. For a buyer comparing quotes in mid-2026, the practical price corridor for a bench / floor-standing 2-head combination weigher in the 5–50 kg packaging band sits around US$1,800–4,500 FOB, while entry-level single-head semi-auto units dip to roughly US$450–1,200 and 10-head multi-head lines for granular product (snack / candy / small parts) start above US$8,000 and climb past US$25,000 with stainless contact parts and servo drives [S4].
The pricing band is wide because the product family is broad: a filling scale covers everything from a single-bucket 5–50 kg gross-weigher for rice or chemical bags, to a 14-head 0.5–5 g combination weigher for freeze-dried coffee, to a rotary filling machine integrated with capping — the latter co-marketed at Interpack 2026 by Jerry Packaging / JPACKS as a "versatile liquid filling & capping system" with 15+ years of OEM experience [S2]. Cost differences between those two extremes are an order of magnitude, and they are not interchangeable in scope.
What the 2026 market actually lists
The Made-in-China.com category for "filling scale price" rendered 183,096 products on 2025-05-13, with best-match sorting default and MOQ filters typically starting at 1 piece for semi-auto units and 1 set for full lines [S4]. Shanghai ELE Mechanical & Electrical Equipment Co. lists rotor-pump filling and capping machines in the same broad category, marketed as "high energy & energy concentrated" with "wide filling scale, speed fast, high accuracy" and a flexible filling style envelope [S3]. That language is the marketing tell: a single model number rarely covers a wide gram range, so the "wide filling scale" claim is almost always paired with a stated minimum/maximum gram window in the datasheet — anything else is filler.
JPACKS / Jerry Packaging's Interpack 2026 push positions the company as a custom filling and packing line builder rather than a catalogue seller, an important distinction because custom line quotes bundle conveyors, fillers, cappers, labelers and checkweighers into one bill of materials [S2]. A buyer comparing a US$2,000 standalone weigher to a US$80,000 turnkey line is not comparing the same scope of supply; the apples-to-apples comparison is the weigher module plus its bench scale checkweigher plus the rejection station, not the headline sticker.
The five price levers that move the quote
Lever 1 — Head count and weighing range. A 2-head 5–50 kg unit clusters at US$1,800–4,500 FOB China; a 10-head 10–1,000 g unit starts around US$8,000 and runs US$15,000–25,000+ with full stainless contact parts [S4]. Head count drives accuracy more than throughput: each additional bucket on a combination weigher subdivides the statistical sample, lifting accuracy from roughly ±0.5–1 g on a 10-head to ±0.1–0.3 g on a 14-head at the same product density.
Lever 2 — Contact-material grade. Powder-coated carbon-steel frames are the price-floor option and are common in dry, non-corrosive packaging. SS304 contact parts add roughly 15–30% to the line item; SS316 (required for dairy, pharma, aggressive chemicals) is typically a further 10–20% on top. The cost is not just the metal — it is the welding, pickling and passivation documentation that food/pharma audits demand.
Lever 3 — IP / washdown rating. An IP65 rating (hosedown) is now the practical floor for any unit sold into a wet or hygienic line; IP66 adds sealed cable glands and stainless fasteners for another 5–10%. Buyers who skip this and place a standard unit in a washdown cell pay for it twice: once in the unit, once in the replacement within 18–24 months.
Lever 4 — Certification stack. CE is essentially default on EU-bound machinery; GMP and ISO 14001 / ISO 45001:2018 declarations appear on the same Made-in-China listings but are not equivalent to a customer audit [S4]. For pharma or food, the real cost adders are FDA-contact or 1935/2004/EC food-grade documentation, which Chinese suppliers typically charge US$500–2,000 per SKU in paperwork and sample testing — small versus the machine cost, but it gates shipment.
Lever 5 — Drive and controls. A basic stepper-driven unit is the cheapest configuration; servo-driven weigh buckets and PLC+HMI controls (Siemens / Mitsubishi / Omron) add US$1,500–5,000 per station. For a 10-head line that is the difference between US$8,000 and US$13,000+ for the same mechanical hardware.
Comparison: which sub-type fits which job
Semi-auto single-head (US$450–1,200, 1–5 kg): workshops and small-batch packers. Throughput 4–10 packs/min, accuracy ±2–5 g, one operator. Not suitable for 24/7 line work. [S1]
2-head 5–50 kg gross weigher (US$1,800–4,500): the workhorse for rice, fertilizer, plastic pellets, chemical powder. Throughput 6–14 bags/min, accuracy ±20–50 g, often paired with a bag-clamp and sewing head. Solid fit for truck scale-adjacent bagging stations where bag weight, not truck weight, is the legal-for-trade point.
10–14 head multi-head weigher (US$8,000–25,000+): snacks, candy, frozen veg, small hardware. Throughput 60–120 weighings/min distributed across 2–4 packs/min at the discharge. This is the category where servo + SS316 + IP65 stacks drive the headline price.
Linear / piston liquid filler (often co-quoted): for viscous or foaming liquids, pricing is governed by nozzle count and CIP capability, not by weigh heads. The JPACKS / Jerry Packaging Interpack 2026 line bundles these with cappers as a single skid [S2].
The decision rule: pick the sub-type by product form and accuracy target, not by sticker price. A 10-head weigher on a 25 kg bag job is over-spec and wastes capacity; a 2-head gross weigher on a 2 g candy job cannot resolve the weight and will not pass a checkweigher.
Who it is for — and who it is not
A filling scale is for a packager who has a defined product (granular size, bulk density, moisture), a defined pack size, and a target throughput in packs per minute. It is not for a contract packer running 30 SKUs a week on one machine — that buyer should be quoting a linear / servo piston filler or a custom turnkey line, not a combination weigher. It is also not for a buyer who needs legal-for-trade retail packs; that path goes through a bench scale checkweigher with OIML R76 / NTEP CC approval, not a combination weigher acting as the metrological authority. [S2]
Hidden cost lines buyers underestimate
Freight for a 10-head line in a wooden crate runs US$1,200–3,500 sea freight from Shanghai to a US or EU port in 2026, and the unit will not clear customs without a CE technical file, a wiring diagram, and a Declaration of Conformity. Installation commissioning adds US$800–2,500 if the supplier sends a technician, or free-of-charge if the buyer accepts a video-call commissioning. None of these are on the OEM sticker. [S3]
For plants already running weighbridges, see the Truck Scale 2026 Price and Cost Guide for the upstream weighing station, and the Truck Scale vs Checkweigher cut for the in-line checkweigher that often pairs with a multi-head filler. For an OEM / custom-line perspective on the broader system, the JPACKS / Jerry Packaging Interpack 2026 page is the cleanest public reference of a Chinese supplier pricing custom filling and packing lines as integrated skids [S2].
Trackable signals to watch next
Two watch-items for the second half of 2026: (1) any post-Interpack 2026 published price lists from European integrators, which usually narrow the FOB-to-landed delta that Chinese catalog pricing hides; (2) any revision to the CE machinery documentation expectations under the EU Machinery Regulation 2023/1230 transition, which takes effect for new placements in the 2026–2027 window and will affect what paperwork Chinese OEMs must ship with a filling scale. Both will move total cost of ownership numbers, even when the unit FOB does not move. [S4]
