I'm Ordering Glass Candle Jars From Another State — What Packaging Should I Expect From a Supplier to Minimise Transit Breakage?

Six layers of a well-packed glass carton

Think of a jar carton from the outside in. Each layer has one job. If any layer is missing, the others have to work harder, and when a carton is dropped, stacked under heavier freight or slid across a loading floor, that is when you find out which layer was missing.

1. The outer carton: strength matched to weight

Corrugated board is described by its plies. A 3-ply (single-wall) board has one fluted layer between two liners; 5-ply (double-wall) has two fluted layers and is generally stiffer and more resistant to crushing and puncture, which is why heavier or more fragile loads are commonly shipped in it. Some suppliers can tell you a burst-strength or edge-crush rating for their cartons; if they can, ask. What you should not see is a thin retail box used as a shipping carton, or a carton bulging at the sides because too much has been forced into it.

2. Isolation: no glass-to-glass contact

Jars that touch chip each other at the rim and shoulder, even without a drop. Two common ways to isolate them: corrugated partitions (a grid of cells, one jar per cell) or individual wrap (each jar in air-column or bubble wrap). Many suppliers use both for larger quantities. Loose jars in a carton with a sheet of paper on top is the arrangement to query.

3. Bottom and top cushioning

The base of a carton takes the drop; the top takes the stack. A pad or layer of cushioning under the bottom row and over the top row keeps jar bases and rims off the board. Where jars are packed in layers, a separator sheet between layers stops the bases of the upper layer landing on the rims of the lower one.

4. Void fill: nothing moves

Empty space inside a carton lets jars build up speed before they hit something. Fill it: scrunched paper, air pillows, extra wrap. Shake the sealed carton gently; if you hear or feel movement, there is not enough fill.

5. Closure: seams taped

Both the top and bottom seams should be taped, with tape running over the edges. A bottom seam held only by folded flaps can open under the weight of glass when the carton is lifted.

6. Weight and marking

Our judgement: a glass carton should be a weight one person can lift and carry comfortably, because heavy cartons tend to be dropped rather than set down. "Fragile" and "this way up" marks do not ensure careful handling, but they help, and upright jars rest on their strongest surface, the base.

A scorecard for the carton that arrives

Use this when a carton of jars arrives, from us or anyone, and send it to your supplier if something falls short. It turns "the packing was bad" into specifics a supplier can fix.

What to ask before you order, and what to do on arrival

Send these questions to every supplier you are considering, in the same words, and keep the replies. CSI's jar listings do not describe how orders are packed or what happens when jars arrive broken, so ask us too.

What a replacement policy is worth in rupees is worked through in the cost-per-usable-jar guide; how breakage and freight fit into a supplier comparison is in the landed-cost guide.

On arrival: six steps, in order

Why another state changes the packaging, not just the freight

A carton going across town may be handled a couple of times. A carton going to another state commonly passes through more hands, vehicles and sorting points, is stacked with other freight, and spends longer in transit. None of that is a reason not to buy from a distant supplier; it is a reason to expect packing built for the longer journey, and to ask.

CSI dispatches from Pune. Delivery times to your state are not published on our listings; ask for a dispatch date with your order. Whether a nearby supplier's shorter route is worth a higher piece price is a separate comparison, set out in the local-versus-distant supplier guide.

Your own parcels: sizing a box around a jar

Once your candles are poured, the breakage that costs most per jar is in your parcels to customers, and that packing is entirely yours. The same six layers apply. A common mistake is box size: too tight and there is no room for cushioning; too loose and the jar moves.

The diagram at the top works through two CSI boxes with two CSI jars, using listed sizes. The 7 × 5 × 4 inch box is 17.8 × 12.7 × 10.2 cm. One jar listed as 7 cm wide and 8 cm tall, such as the White Matte 200 ml ("Height 8 cm width 7 cm"), leaves about 5.4 cm at each end, 2.85 cm at each side and 1.08 cm above and below: comfortable for air-column wrap around the sides, tight top and bottom. Two such jars leave only 1.26 cm between jars and end walls, workable with individual wrap and snug fill, but with no margin. The 11 × 11 × 8 cm mailer gives 2 cm around a 7 cm jar, but a jar about 8 cm tall with its lid, like the Clear Glass Jar with Golden Lid (150 gram), fills its full height.

The 11 × 11 × 8 cm row is arithmetic on listed sizes: 8 cm of height minus about 1 cm top and bottom leaves roughly 6 cm for a jar, so a jar listed at 6.5 cm, such as the 120 g shiny jars, would sit tight. Test it.

CSI packaging for onward shipping

These are the in-stock CSI packaging listings that match the six layers. Crinkle Paper Filler is out of stock in every colour on 26 September 2026, as is the 4.5 × 3 × 2.5 inch box. CSI does not list a double-wall carton or corrugated partitions, so for multi-jar master cartons you will need those from a packaging supplier.

What packaging costs per parcel, and what a breakage costs

Packaging feels expensive until you price a broken candle. Worked example, with CSI prices and one clearly labelled placeholder:

Now the other side. One finished 150 g candle in a White Matte 200 ml jar at 8% (138 g of CSI 464 at the 10 kg price, 12 g of Jasmine at the 1 kg price, one C2 wick) is ₹197.34 of jar and materials, before labour, the second shipment to replace it, and the customer's goodwill. If better packing costs an illustrative ₹10.00 more per parcel, it pays for itself if it prevents one breakage in roughly every 20 parcels.

A drop test before you ship 100

A simple home test, not a certified packaging test, but it catches many packing mistakes before a customer does. Use a finished candle you would otherwise reject, packed exactly as you will ship it.

Packing for Diwali, 8 November 2026

Diwali falls on 8 November 2026, 43 days after these prices were checked. Two things change in festive weeks: networks are busier, and you are packing faster. Drop-test your parcel now, while you have time to change it, and stock packaging with your jars: running out of boxes or wrap in the first week of November is as damaging as running out of jars. If you are receiving jars inter-state for festive production, order early enough to inspect them, reorder any breakage and still pour on time.
