You send us finished bulk. We fill it, close it and label it, then send it back ready for sale. On this service we do not touch the formulation — just the filling operation, run accurately and released with documentation. If you want the product developed too, that is contract manufacturing, and we do that as well.
We've had the pleasure of working with PharmaHemp for several years and are extremely satisfied with our partnership.

Contract liquid filling is a service in which a manufacturer fills a brand’s finished bulk liquid into containers, closes them and applies the labels, returning finished goods ready for sale. The formulation stays with the brand; only the filling operation is outsourced.
Liquid contract filling suits brands where the filling line is the missing piece rather than the product. You already have a bulk liquid you are satisfied with — an oil, a tincture, an emulsion, a lotion — and no equipment to put it into containers accurately, repeatably and with documentation behind it. Buying that equipment means a filling line, a controlled area, trained operators and validation work before a single unit ships.
What this page covers, and what it does not. This is the fill-only route: you send finished bulk and we fill it, without developing, blending or adjusting what arrives. PharmaHemp does also formulate — bulk production, custom formulation and white or private label are real services here — but they are quoted as contract manufacturing, not as filling. And we do not sell filling machines: we run them on your product. If you arrived looking for equipment to buy, this is not that page.
Your liquid arrives as approved bulk, with its specification and your own release documentation.
Your artwork applied, batch coded, packed and shipped back as finished goods.
Almost no contract filler publishes these figures, so a buyer has to ask for all of them before knowing whether a project is even feasible. Ours are below, indexed by viscosity — because viscosity, not the product name, is what decides which line your liquid runs on.
Filling capability by viscosity band.
| Viscosity band | Typical liquids | Fill volume | Filling method | Dosing accuracy | MOQ | Capacity |
|---|---|---|---|---|---|---|
| Under 100 cP | Thin aqueous liquids, tinctures | 1 – 1,000 ml | Peristaltic / piston pump | ± 1 % | 50 units | 6,000 units / day |
| 100 – 1,000 cP | Oils, light emulsions | 1 – 1,000 ml | Peristaltic / piston pump | ± 1 % | 50 units | 6,000 units / day |
| 1,000 – 10,000 cP | Lotions, light gels | 10 – 500 ml | Piston | ± 1 % | 50 units | 1,000 units / day |
| 10,000 – 50,000 cP | Creams, thick gels | 10 – 500 ml | Piston | ± 1 % | 50 units | 1,000 units / day |
| Above 50,000 cP | Balms, salves | 10 – 500 ml | Piston, heat assisted | ± 1 % | 50 units | 1,000 units / day |
If you do not know your product’s viscosity, send a sample and we will measure it. That is the fastest route to an accurate quote, and it avoids the common problem of a filler quoting on a line that turns out to be wrong for the paste once it arrives.
Runs range from pilot batches for market testing through to full production. Batch size, line speed in units per hour and changeover time are confirmed before the quote is issued.
Most contract fillers list what they can fill. Very few say how, which matters, because the wrong method on the wrong viscosity gives you inconsistent fills, foaming, or product left in the hopper.
A piston draws a measured volume and dispenses it. Accurate across a wide viscosity range and the workhorse for oils, emulsions, lotions and creams. Because it measures volume rather than level, the fill stays consistent regardless of container shape.
Oil filling is the largest share of what runs here, and the carrier decides more than the active does. Two tinctures at the same cannabinoid strength can need different nozzles, different line speeds and a different room temperature, purely because of the oil they sit in.
Thin, stable and the easiest carrier to fill accurately. Low enough in viscosity to behave almost like an aqueous liquid, which makes it fast — but thin oils string and drip at the nozzle, so cut-off is what has to be controlled rather than dose.
The practical consequence: the viscosity figure on your specification sheet is only true at the temperature it was measured. Tell us that temperature, or send a sample and we will measure across the range the fill room actually sees. It is the single most common reason a dose that was accurate in a trial drifts in production.
Filling a cannabinoid oil? Bottle sizes, dropper and pipette assemblies, amber glass and light protection are specified on bottle filling services, which also covers CBD oil and tincture bottling. If you already hold bulk oil and want to know what documentation has to travel with it, see sending your own bulk CBD oil for bottling and labelling.
A filling service is only worth what its consistency is worth. These are the controls that hold it, on every run.
Because you supply the bulk, the release documentation covers what we are responsible for: the accuracy of the fill, the integrity of the closure, and the correctness of the label. Your own bulk release stays yours.
Filling is the middle of the job, not the end of it. Every unit still has to be closed to a repeatable torque, sealed, coded and labelled to the artwork you approved — and each of those steps carries a requirement in the markets you sell into.
We close by cap, pump or dropper assembly depending on the container, apply a foil induction seal liner or shrink band where tamper evidence is needed, then batch code: batch number, best-before or expiry date, and a lot code where the market requires one. Labelling covers wrap-around, front and back, and full-body shrink sleeving, applied to your artwork and checked against the approved proof before the run continues.
Our liquid packaging services continue in the same facility — cartoning, inserts, multipacks and transport packaging — so the goods leave palletised and ready to ship rather than needing a second supplier to finish them.
Closure and container detail lives on the container page. Bottle and jar materials, sizes, neck finishes, capping torque and the full closure range are covered under bottle filling services. Tubes are filled too — the tube formats, sealing and crimping detail sits with the products that use them, under contract cosmetic filling.
Liquid filling contract packaging means the fill and everything after it handled by one supplier, under one batch record, with one party accountable for the finished unit.
A product that is filled in one place, labelled in another and boxed in a third has three points where a specification can drift and no single supplier responsible for the result. Running liquid contract packaging in one facility removes the handovers: the batch that was filled is the batch that was coded, labelled, cartoned and palletised, and it is traceable through each step by the same number.
Finished goods can be held in our warehouse and released against your schedule rather than shipped in one consignment — useful when the retail launch date and the production date are not the same date.
Most contract manufacturers answer every question with yes and work out the details later. We would rather you knew the boundary before you send a specification, because a filler that is honest about its scope is faster to work with than one that is not.
This is toll filling in the strict sense: you own the formulation and supply the material, and you pay for the filling operation rather than for goods. Everything in the right-hand column that involves formulation is a different service, not a refusal — bulk production, custom formulation and white or private label are quoted as contract manufacturing.
Tell us which one you actually need and we will quote that instead. Tolling service or filling service — what’s the difference?
On the product side we fill cannabinoid oils and tinctures, water-soluble emulsions, lotions, gels, serums, balms and salves. Carrier oils and how each behaves on the line are covered above; the cosmetic categories, ISO 22716 scope and who holds which obligation under the EU Cosmetic Products Regulation are on contract cosmetic filling.
On the container side we fill glass, PET and HDPE bottles, jars and airless jars, tins and tubes. Sizes, neck finishes, capping torque and the closure range are specified on contract bottle filling, which also covers CBD oil and tincture bottling.
Toothpaste is the exception in this silo: we manufacture it rather than fill client bulk, so it sits on its own page — private label toothpaste manufacturer.
Filling under certification is what separates a contract filler from a pair of hands. Every standard below is held by the facility that will run your product. Ask for the current certificates at any point and we will send them.
Good Manufacturing Practices for cosmetics — governs how cosmetic products are filled, controlled, stored and shipped.
Quality management system. The process that filled your batch is documented, audited and repeatable.
Food safety management, applied to ingestible liquids.
Hazard analysis and critical control points across food-grade filling.
Good manufacturing practice certified for food supplement production, alongside ISO 22000 and HACCP on the same operation.
Every finished unit traces back through the filling record to the bulk lot you supplied.
For cannabinoid liquids, tell us which markets the product is going to. THC limits, labelling rules and Novel Food positions differ by country, and it is better to confirm what the label needs before the run is scheduled than after it has shipped.
A filling quote is only as accurate as the specification behind it. Send us the following and you will get real numbers instead of a range that spans a factor of three.
On minimum order and price. We do not publish a price list, because the same 30 ml bottle can differ by a factor of two depending on the closure, the viscosity and the run size. What we can tell you up front is the range: filling runs start at 100 units. The maximum quantity depends on the product and packaging requirements. Three things move the price — quantity, container and closure complexity, and how the viscosity of your liquid affects line speed and changeover.
Expect a written quote within 3-5 working days of receiving a complete specification, and a trial fill before you commit to a full production run.
Filling runs start at 100 units and scale to full production runs. The practical minimum depends on the container and the viscosity, because changeover time differs — a 10 ml dropper bottle and a 200 ml airless jar are not the same job.
Filling runs under GMP in our certified facility (ISO 22716:2007 for cosmetics, GMP for food supplements). If your product needs aseptic filling or a classified area, tell us at the specification stage and we will confirm whether it can be run.
A written quote follows within 1-3 working days of a complete specification. Production lead time is 2–3 weeks from approved artwork, approved bulk and components on site. Component lead times are usually the longest element, so tell us early if you are supplying your own.
Send your liquid’s viscosity, container spec and run quantity — or just send a sample. Our production team will come back with a written quote and a trial fill plan.
