Private-Label Curry Paste in Sri Lanka: A Range Launch Playbook

Most Sri Lankan brand owners arrive at a curry paste range with the recipes already settled. Four or five pastes, tested in a home kitchen, liked by everyone who tried them. What is not settled is the batch, and the batch is what sets the cost per jar.

The category is worth the trouble. The Sri Lanka Export Development Board reported in July 2026 that processed food earnings grew 44.07 percent year on year in the first half of 2026, while spices and essential oils slipped 0.10 percent. That divergence is the private-label argument in two numbers.

This playbook follows the sequence a mid-sized local FMCG brand meets when it moves a paste range out of a kitchen: kettle economics, format choice, thermal process, minimum order quantity per SKU, and the label-approval window that quietly decides the launch date.

Start with the kettle, not the SKU list

A jacketed steam kettle cooks and discharges one charge at a time, so batch size is fixed by the vessel rather than by the order. At a 300 litre working volume, one charge fills roughly 1,000 jars at a 300 g net weight before line losses, which makes the kettle, not the purchase order, the real unit of production planning.

The second variable is changeover. Every recipe change between charges is a full clean-down of kettle, pump, filler and lines, because a chilli-heavy paste carries into the next batch otherwise. A day running one paste yields more sellable jars than a day running three, on identical equipment. Silk Foods Ceylon runs its semi-liquid line at 3,000 jars per day and prices a first private-label run from 1,500 jars per SKU, a half-day charge plus its clean-down.

Ingredient specification feeds straight back into this. The tolerance bands set when specifying garlic, mustard and fenugreek for condiment SKUs are what let a second charge match the first without a fresh round of adjustment on the floor.

How many pastes should a first range carry?

Three. At the 1,500-jar minimum per SKU, three pastes is 4,500 jars and about a day and a half of line time. Five pastes is 7,500 jars, two additional clean-downs, and 3,000 extra jars of finished inventory carrying a sell-through rate nobody has measured yet.

A brand asking for nine pastes in a first run is usually solving a shelf-facing problem rather than a demand problem, and that is a conversation worth having before the artwork goes to plate. The second run is where the economics improve, and a brand sitting on unsold SKU seven rarely gets to one.

The arithmetic behind that call is set out in the founder’s maths on contract manufacturing costs, which walks the same trade between run size and unit cost.

Jar or pouch, and what the format actually costs

Format choice is a cost-floor decision made before the first sample, because it fixes the thermal process, the freight weight per unit, and the print minimum on the packaging. The four formats a local paste range realistically chooses between behave quite differently.

Format	Typical fill	Thermal process	Ambient shelf life (planning figure)	Where it fits
300 g glass jar, lug cap	250 to 380 g	Hot fill if acidified, retort if not	12 to 18 months	Supermarket condiment shelf, gifting, hotel table use
Retort pouch, printed laminate	100 to 250 g	Full retort	12 to 18 months	Price-led shelf, e-commerce, lower freight per unit
Food-service pouch or pail	1 to 5 kg	Full retort	9 to 12 months	Hotel and restaurant kitchens, central production units
Single-portion sachet	30 to 60 g	Full retort	9 to 12 months	Trial size, on-pack promotion, tourist retail

Those shelf-life figures are planning numbers for scheduling and artwork lead time. The life declared on the label comes from a study on the finished pack, not from a category average.

Glass carries a higher packaging cost per unit and far more freight weight than an equivalent pouch, and it reads as a gift-ready pack in a way laminate does not. The pouch wins on cost and freight, and loses on one detail that catches brands out: printed laminate carries a converter print minimum commonly well above 1,500 units, so the packaging order can be several times the size of the first product run. The jar route splits that exposure across a plain jar, a stock cap and a printed label, each with a smaller minimum of its own.

The glass-jar route at first-run scale is worked through in more detail for glass-jar retail SKUs from a 1,500-jar first run. For dry blends and refill formats alongside a wet paste range, the spice and herb co-packing capability one-pager covers the sack and pouch side.

What actually sets the shelf life

Shelf life is not a number chosen at the artwork stage. It is an output of four things: pH, water activity, the thermal process the pack receives, and the barrier the pack provides. Of those, pH decides the process, and the process decides most of the cost. The Codex Alimentarius code of hygienic practice for low-acid and acidified low-acid canned foods, adopted in 1979 with editorial corrections in 2011, puts the line at an equilibrium pH of 4.6.

A paste held below 4.6 by tamarind, lime or added acetic acid counts as an acidified food and can be hot filled. A paste above 4.6 is a low-acid food in a hermetically sealed container and needs a validated retort schedule. The University of Georgia Cooperative Extension stated the practical difference in 2025: a product at or above pH 4.6 requires a thermal process under pressure at 240 to 260 degrees Fahrenheit, roughly 116 to 127 Celsius. That single measurement moves the capital requirement, the cycle time per batch, and the shelf life the brand can print.

The clause worth reading twice is the Codex definition of a low-acid food, which bites where any component has a pH above 4.6 and a water activity above 0.85. A paste with an acidified continuous phase but low-acid particulates, coconut, dhal or dried fish, is still a low-acid food. Measuring the blended sample and stopping there is one of the more common ways a brand specifies the wrong process.

One local brand brought a chilli and garlic paste that measured pH 4.4 in its kitchen and drifted to 4.7 at pilot scale, because the kitchen version used close to twice the lime juice per kilo and nobody had written that down. The fix was a formulation change, not a process change, and it cost two sample iterations. Catching it after 1,500 jars were filled would have cost the run.

That gap between a kitchen recipe and a validated batch is the usual reason a first range needs formulation work at all, and reformulating a kitchen recipe for retort runs covers what changes and why.

MOQ per SKU, and why a range multiplies it

Minimum order quantity at Silk Foods Ceylon is set per SKU, not per order, because each SKU is its own kettle charge and its own clean-down. A three-paste range therefore starts at 4,500 jars, not 1,500.

Item	Minimum at Silk Foods Ceylon	Note
Finished paste, 300 g glass jar	1,500 jars per SKU	About half a day on a 3,000 jars per day line
Bulk spice or herb raw material	50 kg per SKU	Volume tiers at 500, 1,000 and 2,500 kg
R&D iterations before recipe lock	2 to 4 samples	2 to 4 weeks per iteration
Sample dispatch, existing recipe	1 to 2 weeks	No formulation work required
Purchase order to dispatch, existing recipe	2 to 3 weeks	Packaging already at the facility
Purchase order to dispatch, new formulation	6 to 10 weeks	Includes R&D iterations and pilot validation

The multiplication bites hardest on packaging rather than product. Jars, caps, labels and cartons each carry a supplier minimum set by the converter, not by the manufacturer, so a brand ordering exactly 4,500 jars usually ends up holding label stock for a second run whether it planned one or not.

The same MOQ-versus-lead-time trade shows up on the hospitality side, where MOQ and lead time for a HORECA private label sets out how a food-service pack changes the arithmetic.

The label-approval window is where range launches slip

Sri Lanka Standards Institution certification is what gates a packaged paste onto a national retail shelf, and it runs per SKU. Silk Foods Ceylon plans 4 to 8 weeks per SKU for a stable formulation, and holds a 6 to 10 week buffer between manufacturer QA sign-off and the target shelf date. The mistake that costs range launches a month is filing SKU one, waiting, then filing SKU two. Filed together, three SKUs take one window. Filed in sequence, they take three.

Underneath SLSI certification sits the Sri Lanka Food Act No. 26 of 1980 and the labelling regulations made under it. The 2005 regulations, gazetted as Extraordinary No. 1376/9, require the common name of the contents on the main panel in at least two of the three languages and the net contents in metric symbols, and on any panel a complete ingredient list in descending order of proportion, storage instructions, a batch or code marking, the date of manufacture and the date of expiry. That descending-order clause is what ties artwork to the recipe. An R&D iteration that raises the garlic above the onion reorders the declaration, and a declaration change after plates are cut is a reprint.

Two numbers in the same gazette decide how much of the jar the designer actually gets. The main panel must be at least 20 percent of the total surface area excluding the bottom of the container, and the common-name lettering must be at least one third the height of the brand-name lettering, with a minimum of 3 millimetres. Prepackaged food under 25 grams is exempt, which matters if the range carries a trial sachet. The regime is also moving: the USDA Foreign Agricultural Service reported in February 2025 that implementation of the 2022 labelling regulations, which require the common name in bold in all three languages rather than two, moved to 1 July 2025 by gazette Extraordinary No. 2416/51.

Silk Foods Ceylon runs a BRCGS-audited site operating to FSSC 22000 V6, which no local shelf requires. SLSI certification and Food Act compliance are the floor. The audited stack is what a premium private-label programme, a hotel-group listing or a first export enquiry asks for, so it matters to a brand that expects to be somewhere else in two years.

One conditional worth settling early: a culinary paste sold without a traditional-medicine claim sits outside Department of Ayurveda registration. Add claim language drawn from an Ayurvedic monograph to the pack and it does not, which is a different path on a different timeline.

For a worked example of the submission window on a comparable jarred SKU, see the SLSI clearance window for private-label jars.

A fourteen-week sequence from brief to shelf

The sequence below assumes three SKUs, a 300 g glass format, and formulation work on at least one paste. A stable existing recipe with packaging already in hand compresses this to the 2 to 3 week purchase-order window instead.

Week	Step	Owner
1	Brief, format choice, target retail price and channel confirmed	Brand
2 to 5	R&D iterations, pH and viscosity checks at pilot scale, 2 to 4 samples	Silk Foods Ceylon
5	Recipe and ingredient declaration locked for all three SKUs	Joint
5 to 7	Artwork built on the locked declaration, print plates ordered	Brand
6 to 13	SLSI submissions filed in parallel across the range	Joint
8	Jars, caps, labels and cartons delivered to the facility	Brand
12	First commercial run, 1,500 jars per SKU	Silk Foods Ceylon
13 to 14	QA release, shelf-life study started on finished pack, dispatch	Silk Foods Ceylon

Two dependencies break this schedule more often than anything else: artwork committed to plate before the declaration locked, and SLSI submissions filed one after another. Both are calendar problems rather than manufacturing problems, and both are fixed at week one for free.

Frequently asked questions

What is the private-label MOQ for a curry paste at Silk Foods Ceylon?

A first commercial run starts at 1,500 jars per SKU in 300 g glass, about half a day on a line rated at 3,000 jars per day. Bulk spice and herb raw material carries a separate 50 kg per SKU minimum, with volume tiers opening at 500, 1,000 and 2,500 kg.

Does a Sri Lankan curry paste need retort processing?

It depends on acidity. pH 4.6 is the recognised boundary between acid and low-acid foods, so a paste acidified below 4.6 with tamarind, lime or acetic acid can be hot filled, while a coconut-rich or low-acid paste above 4.6 needs a validated retort schedule.

How long does SLSI clearance take for a private-label SKU?

Plan 4 to 8 weeks per SKU for a stable formulation, and hold a 6 to 10 week buffer between manufacturer QA sign-off and the target shelf date. Filing a multi-SKU range together rather than one SKU at a time is what stops those windows stacking end to end.

Glass jar or retort pouch for a first paste range?

Glass suits the supermarket condiment shelf and gifting, and allows hot fill if the paste is acidified. Retort pouches cut packaging cost and freight per unit, but printed laminate carries a converter print minimum often several times the 1,500-jar product minimum, so the format sets the packaging inventory too.

Can Silk Foods Ceylon develop a new paste recipe for a local brand?

Yes. The in-house R&D team typically runs 2 to 4 sample iterations before a recipe locks, at 2 to 4 weeks per iteration, with pH and viscosity confirmed at pilot scale rather than kitchen scale. A purchase order carrying new formulation work dispatches in 6 to 10 weeks.

How Silk Foods Ceylon can help

For local FMCG brands shifting from in-house production to professional contract manufacturing, Silk Foods Ceylon (SFC) operates a 10,000 sq ft cellular-manufacturing facility in Matale with the line flexibility to run 50+ ready-to-go SKUs on a single BRCGS- and FSSC 22000 V6-audited cert stack. Capacity ranges across formats: 3,000 jars/day on semi-liquids, 2,500 x 200 ml bottles/day on beverages, 200,000 capsules/day, 15,000 patties/day, 30,000 nuggets/day. The in-house R&D team works alongside production planning, which means a multi-SKU launch can run in parallel rather than serial. SLSI submission support sits inside the standard engagement.
