Spices and dry mixes
Dry blending for spices, seasonings, and drink powders
Dry blending combines measured dry ingredients into a uniform batch before packing. To find a manufacturer, share your formula status, ingredient list, batch size, fill weight, and package direction. Confirm whether the company blends, fills, or does both. A dry product still needs a product-specific food safety review.
Prepare a spice blend, seasoning mix, or drink powder for manufacturing. Plan formula, blend size, ingredient sourcing, packaging, and your first quote.

Who this is for
First-time makers of spice blends, dry rubs, seasonings, drink powders, soup mixes, and baking mixes. A dry food blend and a dietary supplement can have different requirements; confirm which scope applies before comparing manufacturers.
01 / Start here
What should you do first?
Describe the blend and the work you need
Name the product and distinguish mixing ingredients from filling a supplied powder. State whether the formula is a home recipe, a measured draft, or a commercial specification. List the parts that are fixed and the parts you can change.
Put the formula into measurable terms
Bring ingredient weights or percentages, suppliers, and specifications when available. Discuss particle size, density, flow, dust, and clumping with the plant. A fine powder and a large dried herb may need different handling to stay evenly distributed.
Have the safety and allergen needs reviewed
Do not assume that no added water means no hazards. Ask a qualified food-safety professional and the manufacturer to review ingredient hazards, supplier controls, sanitation, allergens, and any necessary testing or treatment. FDA preventive-controls requirements depend on the product and facility.
Choose the package with the filling line
Identify a bulk bag, pouch, jar, shaker, tub, stick pack, or sachet and the target fill weight. Ask the filler to confirm format, material, seal, and label fit before buying packaging. A company that blends your formula may use a separate partner to fill it.
Compare the full first-run quote
Request separate lines for development, ingredients, blending, testing, changeover, filling, packaging, storage, and freight. Ask for the minimum per formula and package, plus the number of batches or SKUs included. Leave unavailable numbers unknown.
Agree on the trial and release criteria
Ask how samples will be taken, how blend uniformity will be assessed, and who approves the finished product. Record formula ownership, ingredient substitutions, lot coding, storage, and the checks needed before shipment.
02 / Get ready
What should you have ready?
Keep track of what you have worked through. “I’m not sure yet” is still a useful answer.
- Product description and formula stage
- Ingredient weights or percentages, if known
- Ingredient suppliers and specifications
- Known allergens and intended label claims
- Target blend weight and number of SKUs
- Package direction and fill weight
- Storage and shelf-life goals for review
- Who buys ingredients, packaging, and labels
- First-run timing and destination
- Open questions clearly marked as unknown

03 / Choose your path
Which choices shape the project?
| Custom blend or private label | A custom project uses your formula or develops one with the plant. Private label may use an existing blend. Ask what can change and who owns the formula. |
|---|---|
| Blending or filling only | A packer may accept finished powder without mixing ingredients. Confirm who blends, samples, fills, seals, and holds the manufacturing records. |
| Customer-supplied or plant-sourced ingredients | Material sourcing and supplier approval affect the quote and schedule. Do not send ingredients before the plant accepts them. |
| Bulk or retail pack | A large bulk bag and a small stick pack need different filling arrangements. Compare minimums for the actual format. |
04 / Understand the words
Which words should you know?
- Dry blending
- Mixing measured dry ingredients into a uniform batch.
- Blend uniformity
- How consistently ingredients are distributed through a batch. Ask how the manufacturer measures it for your formula.
- Tolling
- Manufacturing or packing work using some or all materials supplied by you. Confirm the exact scope in writing.
- Stick pack
- A narrow packet for a small portion, such as drink powder. Confirm the machine and fill range.
- Lot code
- An identifier connecting finished packs to a production batch and its records.
05 / Reach out
What should you ask a manufacturer?
You can copy these into your first email.
- Do you blend my formula or only fill a supplied blend?
- Which ingredient specifications and batch weight do you need to assess equipment fit?
- How do you confirm blend uniformity?
- What supplier, allergen, sanitation, and product-testing controls apply?
- Can I supply ingredients or packaging, and what approval is required?
- Which package and fill-weight combinations can this line run?
- Who owns the formula, specifications, samples, and records?
- What is the minimum for this exact formula and package?
- Which costs are separate from the production price?
- What remains unresolved until a trial?
Which mistakes should you avoid?
- Treating a dry product as safe solely because no water is added
- Assuming the blender also fills and ships
- Ordering printed film before confirming line fit
- Claiming allergen-free without reviewing cross-contact and labeling
- Comparing a bulk minimum with a retail-unit minimum
- Treating an unfinished formula as a final production specification
What else do founders ask?
Does dry blending include a kill step?
The term only describes mixing dry ingredients. Ask whether treatment is needed, where it occurs, and how ingredient and process hazards are controlled. Blending alone does not establish product safety.
Can I use my own ingredients?
Ask the manufacturer. Some projects use customer-supplied materials, but acceptance, supplier approval, and receiving requirements vary. Get agreement before shipping anything.
What if my formula is not finished?
Say so in the brief. Ask whether the manufacturer offers formulation, sample work, or a manufacturability review and what those services cost.
How small can my first powder run be?
There is no universal minimum. Ask for the blend minimum, filling minimum, and packaging purchase separately, with units and any per-SKU conditions.
