How an FMCG Supply Chain Can Scale for the Diwali Peak Season in Chennai

Diwali creates a predictable but intense peak in demand across retail, FMCG, e-commerce and logistics.

For warehouse operators and occupiers, the challenge is not simply finding more storage space. A peak-season strategy has to address storage capacity, manpower, order processing, dispatch capacity and transportation simultaneously.

This is where an elastic warehousing model becomes useful: instead of permanently leasing excess warehouse space and staffing for the highest annual demand, businesses can add capacity for the peak period and scale it back afterward.

Importantly, there is no universal requirement such as “add 10,000 sq ft within seven days.” The amount and timing depend on inventory, throughput and the facility. Where specific company data is not publicly verified, this guide does not invent it.

The Problem: Diwali Creates a Short-Term Capacity Spike

Festive demand can put pressure on the entire logistics network.

During India's 2025 festive season, logistics companies reported expectations of a 20–40% increase in demand, while warehouses and fulfilment networks faced pressure from higher order volumes and limited capacity.

The impact is not limited to transportation.

A warehouse may simultaneously experience:

• Higher inbound inventory

• Greater storage requirements

• More picking activity

• More packing requirements

• Higher dispatch volumes

• Greater demand for warehouse labour

• Increased vehicle requirements

For an FMCG company, this creates a capacity problem:

The warehouse that is sufficient during an ordinary month may not have sufficient operational capacity during the Diwali peak.

The Solution: Build Elastic Capacity

An elastic warehousing strategy allows the business to increase capacity temporarily rather than permanently sizing the facility for its annual peak.

This can involve three areas:

1. Space

Additional warehouse or overflow capacity can be secured for the peak period.

2. Manpower

Temporary or additional workers can be deployed for warehouse activities such as picking, packing, sorting and loading.

3. Throughput

The warehouse can increase its operating capacity through additional shifts, better scheduling, process changes and technology.

The important point is that space and manpower should be scaled according to the expected increase in throughput, rather than simply adding a fixed percentage.

What Does This Look Like in Chennai?

Chennai is already a major industrial and logistics market, with established warehousing corridors across the western, northern and southern parts of the metropolitan region.

Savills reported that manufacturing, retail, 3PL and FMCG/FMCD occupiers were among the segments driving Chennai's industrial and logistics demand in H1 2025.

For a company serving Chennai consumers, temporary capacity could potentially be positioned closer to the relevant consumption clusters rather than adding all additional inventory to a single regional warehouse.

The appropriate solution depends on the distribution network.

Step 1: Forecast the Peak Inventory

The first step is to estimate how much additional inventory will actually be required.

For example, a company could compare:

Normal inventory requirement

versus

Expected pre-Diwali inventory requirement

The difference determines the additional storage requirement.

This should be calculated using the company's own historical sales, promotional plans, purchase orders and inventory policy.

There is no defensible universal rule that says every FMCG company should add a particular percentage of warehouse space for Diwali.

Step 2: Convert Inventory Into Warehouse Space

Additional inventory does not necessarily translate directly into an equivalent increase in warehouse square footage.

The required area depends on:

• Pallet configuration

• Racking

• Stack height

• SKU characteristics

• Packaging

• Aisle configuration

• Picking method

• Staging requirements

• Fire and safety requirements

For example, adding 10,000 sq ft of floor area does not necessarily mean that exactly 10,000 sq ft of additional inventory capacity is available.

This is why warehouse planning should begin with pallet positions, cubic capacity or inventory units, rather than simply square footage.

Step 3: Secure Temporary Capacity Early

One of the most important lessons from the 2025 festive season was that companies were planning additional warehouse capacity well before the peak.

In August 2025, Mint reported that warehousing companies were creating temporary storage capacity in key hubs, including Chennai, specifically to address festive demand. Allcargo Supply Chain said it planned to add 70,000–100,000 sq ft in Chennai for the festive season.

This is a useful real-world example of temporary capacity planning.

It should not, however, be interpreted as a standard requirement for every Chennai occupier.

The additional capacity required by an individual business will depend on its inventory and throughput.

Step 4: Scale Manpower Alongside Volume

Additional space is of limited value if there are not enough people to operate it.

Festive-season staffing typically affects:

• Picking

• Packing

• Sorting

• Loading

• Dispatch

• Inventory handling

In July 2025, industry reporting indicated that companies across consumer goods, e-commerce and logistics were planning 20–25% higher temporary hiring requirements for the festive season compared with the previous year.

Separately, an Adecco-backed report estimated more than 216,000 seasonal jobs across India during H2 2025, with logistics, retail, e-commerce and FMCG among the sectors driving demand.

Again, these are industry-level figures, not a prescription that a particular Chennai warehouse should increase its workforce by 20–25%.

Step 5: Increase Throughput, Not Just Headcount

Adding workers does not automatically increase warehouse output.

The operation also needs to consider:

• Shift structure

• Picking routes

• Order batching

• Packing stations

• Loading schedules

• Dock availability

• Inventory positioning

• Vehicle scheduling

For example, fast-moving Diwali SKUs can be positioned closer to picking and dispatch areas where the warehouse layout permits.

The objective is to reduce unnecessary movement and congestion during the peak period.

Step 6: Create an Overflow Strategy

Temporary storage does not necessarily mean taking an entire additional warehouse.

Depending on the operation, overflow capacity could involve:

• Temporary additional warehouse space

• A nearby warehouse

• A dedicated 3PL facility

• A short-term storage arrangement

• Additional capacity within an existing logistics park

The appropriate option depends on inventory characteristics and the required service level.

For FMCG products, the location of overflow inventory also matters. Moving fast-moving products too far from the primary distribution area can increase transportation requirements and potentially offset the benefit of additional storage.

Step 7: Use Chennai's Logistics Corridors Strategically

Chennai's warehouse market is distributed across several major corridors.

Depending on the distribution network, an occupier may evaluate:

Western Chennai

Sriperumbudur and Oragadam

Useful for large-format industrial and logistics operations and regional distribution.

Northern Chennai

Madhavaram, Red Hills and surrounding corridors

Relevant for distribution into northern and central Chennai markets.

Southern Chennai

GST Road and Maraimalai Nagar

Relevant for businesses serving southern Chennai and the wider southern corridor.

The best location is determined by the company's actual customer and delivery network rather than by the availability of the cheapest warehouse.

A Real Chennai Example: Temporary Capacity

A useful documented example comes from the 2025 festive season.

Allcargo Supply Chain reported plans to temporarily add 70,000–100,000 sq ft of warehousing capacity in Chennai ahead of the festive period. The company also expected a 20–40% increase in demand across consignment transport, sorting centres and distribution/logistics parks.

This demonstrates the principle of temporary capacity expansion at a real market participant.

It does not establish that every company needs 70,000–100,000 sq ft, nor does it establish a particular number of days required to secure the space.

The Data: What the Market Tells Us

Metric	Published 2025 Data
Expected festive logistics demand increase	20–40%
Seasonal temporary hiring increase reported by staffing firms	20–25% YoY
Allcargo planned additional Chennai warehouse capacity	70,000–100,000 sq ft
Additional Bengaluru warehouse capacity planned by Allcargo	40,000 sq ft
Additional Kolkata warehouse capacity planned by Allcargo	17,000 sq ft
Estimated seasonal jobs across India	216,000+

These are reported industry/company figures from the 2025 festive season, not standard benchmarks for every warehouse.

What an Elastic Warehouse Plan Could Look Like

For a hypothetical FMCG occupier, the planning process could look like this:

8–12 weeks before peak

• Forecast Diwali demand

• Identify additional inventory

• Calculate required storage

• Identify additional labour requirements

• Review transportation capacity
  

4–8 weeks before peak

• Secure additional warehouse capacity if required

• Recruit or allocate temporary manpower

• Reconfigure inventory

• Confirm transport partners

• Establish additional shifts if necessary
  

1–2 weeks before peak

• Move additional inventory into position

• Test warehouse processes

• Confirm labour rosters

• Confirm vehicle availability

• Establish daily throughput monitoring
  

During peak

Monitor:

• Orders received

• Orders dispatched

• Inventory levels

• Picking productivity

• Dock utilisation

• Labour attendance

• Vehicle availability

• Delivery performance
  

The exact timeframe should be adapted to the company's operation and local availability. There is no verified industry-wide standard saying temporary warehouse space can or should always be added within seven days.

What Happens After Diwali?

Elasticity works in both directions.

Once peak demand subsides, the company should be able to:

• Reduce temporary labour

• Release temporary storage

• Return to normal shifts

• Consolidate inventory

• Reduce additional transportation capacity

This is one of the principal advantages of temporary capacity over permanently leasing a facility sized for the highest demand period.

However, the financial benefit depends on the commercial terms of the temporary space and the cost of scaling the operation.

Why Elasticity Matters for FMCG Companies

A permanent warehouse designed around the Diwali peak may remain underutilised for much of the year.

An elastic model attempts to align capacity more closely with actual demand.

The concept can be summarised as:

Normal demand → normal warehouse capacity

Peak demand → additional space + additional manpower + additional throughput

Post-peak → return toward normal capacity

This approach can help companies avoid carrying permanent capacity that is required only for a limited period.

Frequently Asked Questions

How much additional warehouse space does an FMCG company need for Diwali?

There is no universal percentage or square-foot requirement.

The requirement should be calculated from projected additional inventory, pallet positions, SKU characteristics and warehouse configuration.

Can temporary warehouse space be added for Diwali?

Yes. The Indian logistics market includes examples of companies adding temporary warehouse capacity ahead of the festive season. Allcargo, for example, announced plans for 70,000–100,000 sq ft of additional Chennai capacity for the 2025 festive season.

How quickly can a temporary warehouse be arranged?

There is no reliable industry-wide timeframe that applies to every Chennai warehouse.

Availability, building specifications, approvals, lease terms, fit-out requirements and location all affect the implementation time.

Should manpower increase by the same percentage as warehouse space?

No.

Manpower should be linked to throughput and process requirements, not simply square footage.

Is temporary warehousing better than leasing a larger warehouse permanently?

Not necessarily.

It depends on the company's annual demand pattern, lease terms, storage requirements and cost of temporary capacity.

Final Takeaway

Diwali peak planning is fundamentally a capacity-management exercise.

For an FMCG company operating in Chennai, an effective peak-season strategy can combine:

Demand forecasting + temporary storage + seasonal manpower + additional shifts + inventory positioning + transportation planning.

Market evidence shows that this approach is already being used at scale. During the 2025 festive season, logistics companies expanded warehouse capacity and workforce in anticipation of higher demand, including a reported 70,000–100,000 sq ft temporary capacity addition planned in Chennai by Allcargo Supply Chain.

The important point for an occupier is that elasticity should be designed around its own demand profile.

There is no credible basis for claiming that every company can add a specific amount of space within a fixed number of days. The right solution is to determine how much capacity is required, where it should be located, when it is needed and how quickly it can be operationalised.

For Chennai Warehouses, that is the more useful way to approach Diwali warehousing: plan for the peak without permanently paying for it all year.

How FMCG and E-Commerce Supply Chains Scale for the Diwali Peak Season in Chennai

Diwali creates a recurring peak in demand for consumer goods, e-commerce and logistics businesses. For warehouse occupiers, the challenge is to increase capacity without carrying the cost of peak-season infrastructure throughout the year.

The practical solution is elastic warehousing: adding temporary storage, labour and operational capacity when demand increases, and reducing that capacity after the peak.

There is no universal formula for how much space or manpower a business should add. The requirement depends on inventory, order volumes, product characteristics and the distribution network.

The Challenge: Managing a Short-Term Demand Peak

Festive demand can put pressure on several parts of the supply chain simultaneously:

• Warehouse storage

• Inbound receiving

• Picking and packing

• Order processing

• Dispatch

• Transportation

• Last-mile delivery

• Warehouse manpower

The pressure on logistics capacity is well documented. Ahead of the 2025 festive season, Allcargo Gati expected a 20–40% increase in demand across its consignment transport, sorting-centre and distribution/logistics-park operations.

This is an industry/company forecast, not a standard growth assumption for every FMCG or e-commerce business.

The Solution: Elastic Warehousing

An elastic warehousing model allows a company to increase capacity temporarily rather than permanently leasing space designed for its highest annual demand.

The three main levers are:

1. Additional Space

Temporary or short-term warehouse capacity can be added to accommodate additional inventory.

2. Additional Manpower

Additional workers can be deployed for activities such as picking, packing, sorting and loading.

3. Additional Throughput

Existing facilities can potentially process more volume through additional shifts, better scheduling, inventory positioning and process optimisation.

These three elements need to be planned together. Adding warehouse space without sufficient labour or dispatch capacity does not necessarily increase actual throughput.

A Real Chennai Example: Adding Temporary Warehouse Capacity

There is a documented example from the 2025 festive season that demonstrates how this model works in Chennai.

Allcargo Gati announced that it planned to add 70,000–100,000 sq ft of warehousing space in Chennai ahead of the festive period. The company also announced a 30% increase in its workforce and expected a 20–40% increase in demand.

This is a useful real-world example of temporary capacity expansion.

However, it should not be presented as a benchmark saying that every Chennai occupier needs 70,000–100,000 sq ft or a 30% workforce increase. Those figures relate specifically to Allcargo Gati's 2025 festive-season plans.

Other logistics companies were also preparing flexible capacity. Mint reported that IndoSpace was creating short-term storage capacity in key consumption markets including Chennai, while TVS Industrial & Logistics Parks expected festive-season throughput to be 15–25% higher than regular months and offered additional workforce support to clients when requested.

The Data

Metric	Verified 2025 Example
Allcargo Gati's expected festive demand increase	20–40%
Additional Chennai warehouse space planned by Allcargo Gati	70,000–100,000 sq ft
Allcargo Gati workforce increase	30%
TVS ILP expected festive throughput increase	15–25%
Additional workforce support	Offered to clients by TVS ILP on request

These figures represent specific company announcements and expectations for the 2025 festive season, not universal industry benchmarks.

How Much Space Does a Business Actually Need?

There is no factually defensible rule such as:

“Add 10,000 sq ft for every 20% increase in Diwali demand.”

Warehouse space cannot be calculated from sales growth alone.

The requirement depends on:

• Additional inventory

• Number of SKUs

• Pallet dimensions

• Storage configuration

• Stacking height

• Racking system

• Product characteristics

• Required staging space

• Inbound and outbound volumes

For this reason, an occupier should calculate additional pallet positions or cubic capacity first, and then convert that requirement into warehouse area.

How to Scale Manpower

Manpower requirements should also be linked to operational volumes rather than warehouse area alone.

Additional staff may be required for:

• Receiving

• Put-away

• Picking

• Packing

• Sorting

• Loading

• Inventory handling

A 30% workforce increase may be appropriate for one operation and excessive for another.

For example, a highly automated warehouse may require less additional labour for a given increase in throughput than a predominantly manual operation.

The correct approach is therefore:

Forecast additional workload → calculate required labour hours → determine staffing requirement.

When Should Additional Capacity Be Added?

The timing depends on the business's inventory cycle and warehouse availability.

A typical planning sequence can be:

Demand Planning

Analyse previous festive-season performance and current sales forecasts.

Capacity Planning

Calculate the additional inventory, storage positions, labour and throughput required.

Space Procurement

Identify available short-term or flexible warehouse capacity.

Operational Preparation

Arrange manpower, equipment, systems and transportation.

Inventory Positioning

Move appropriate inventory into the additional capacity before demand peaks.

Peak Operations

Monitor daily inventory, orders, picking, dispatch and vehicle capacity.

There is no reliable industry-wide evidence supporting a fixed implementation period such as seven days for adding temporary warehouse space in Chennai. The actual timeframe depends on availability, facility specifications, commercial terms, fit-out requirements and the operation's readiness.

Where Should Temporary Capacity Be Located?

The location of additional capacity should be determined by the distribution network.

Chennai's industrial and logistics market has established warehouse clusters around areas including:

• Sriperumbudur

• Oragadam

• Thiruvallur

• Madhavaram

• Red Hills

• Ambattur

• GST Road/Maraimalai Nagar

The appropriate location depends on where inventory originates and where customers are located.

For an e-commerce operation focused on Chennai deliveries, proximity to consumption areas may become particularly important during a short peak period.

For a regional FMCG distribution operation, highway connectivity and access to the wider Tamil Nadu market may be more important.

Temporary Space vs. Permanent Warehouse Expansion

The decision is essentially a capacity-utilisation question.

Permanent Expansion

A company may choose a larger warehouse when:

• Demand has structurally increased

• Higher volumes are expected throughout the year

• Existing capacity is consistently constrained

• Long-term warehouse utilisation justifies the additional commitment

Temporary Expansion

Short-term capacity may make more sense when:

• Demand is strongly seasonal

• Additional inventory is required only temporarily

• The company wants to avoid permanently carrying excess capacity

• Suitable short-term warehouse space is available

Neither approach is automatically cheaper. The decision should be based on the company's forecast and commercial terms.

The Importance of Overflow Storage

An occupier does not necessarily need to take an entire additional warehouse for the festive season.

Depending on availability, options can include:

• Additional space within the existing facility

• A nearby warehouse

• A short-term warehouse arrangement

• A 3PL facility

• Overflow storage in another suitable facility

The choice depends on the nature of the inventory and the required service level.

For fast-moving products, moving inventory to a distant overflow location can increase transportation requirements. In that situation, the cost of the additional space should be considered together with the additional movement cost.

Scaling Down After Diwali

Elastic capacity should work in both directions.

Once the festive peak has passed, a business can potentially:

• Release temporary warehouse space

• Reduce temporary labour

• Return to normal shifts

• Consolidate inventory

• Reduce additional transportation capacity

This is the central principle of elastic warehousing:

Capacity increases when demand requires it and reduces when the peak passes.

What Chennai Warehousing Occupiers Should Plan

Before the Diwali peak, an FMCG or e-commerce occupier should establish five numbers:

1. Additional Inventory

How much additional stock will actually enter the network?

2. Additional Storage

How many additional pallet positions or cubic metres are required?

3. Additional Throughput

How many additional orders, cases or units must be processed?

4. Additional Labour

How many additional labour hours are required to process that volume?

5. Additional Dispatch Capacity

Can the loading docks, vehicles and transportation network handle the additional output?

These numbers provide a more reliable basis for peak planning than simply adding a percentage to warehouse area.

Frequently Asked Questions

How much additional warehouse space is required for Diwali?

There is no universal requirement. It should be calculated from additional inventory and the warehouse's storage configuration.

Can companies use temporary warehouse space in Chennai?

Yes. Temporary and flexible warehouse capacity is used in the market. Allcargo Gati, for example, announced plans for 70,000–100,000 sq ft of additional Chennai warehouse capacity for the 2025 festive season.

How quickly can additional warehouse space be arranged?

There is no verified standard timeframe applicable to all Chennai facilities. Availability, lease terms, building specifications and operational requirements determine the actual timeline.

Should manpower increase by the same percentage as demand?

Not necessarily. Staffing should be calculated from the additional workload and productivity of the warehouse operation.

Is temporary warehousing always more economical?

No. The economics depend on the cost of temporary capacity, permanent warehouse rent, utilisation, handling requirements and transportation costs.

Conclusion

Diwali peak planning is not simply about finding more warehouse space.

An effective peak-season strategy connects:

Demand forecasting → inventory planning → storage capacity → manpower → warehouse throughput → transportation.

The Chennai market provides a clear example of this approach. Ahead of the 2025 festive season, Allcargo Gati announced 70,000–100,000 sq ft of additional Chennai warehouse capacity, alongside a 30% workforce increase, while expecting a 20–40% increase in demand.

Other logistics operators were also preparing flexible capacity and workforce support for the festive period.

For an occupier, however, those numbers should be treated as market examples, not formulas.

The right Diwali warehousing strategy is to determine exactly how much additional inventory must be stored, how much throughput must be processed, where the capacity should be located and how long it will be required.

That is the practical meaning of elastic warehousing: scaling capacity for the peak without permanently carrying the full cost of that peak throughout the year.
