How leather cricket balls are made
Meerut district lists balls among its One District One Product sports goods, and Jalandhar's district portal names cricket balls among the city's exports. NITI Aayog's 2026 report puts hard balls in the group of products made by lamination, bonding and sewing, the most labour-intensive part of the industry.
A leather ball is built from the inside out. The core, or quilt, is cork and rubber in layers wound tightly with twine and moulded round. The cover is cut from dyed leather into four quarters, or two halves on cheaper balls. On a four-piece ball the quarters are stitched in pairs with an internal quarter seam, then the two halves are closed around the core with the main seam, sewn by hand through the leather. The ball is pressed in a die, the seam is raised and set, and the cover is stamped, dyed and finished. Red balls are usually greased or polished; white and pink balls carry a coloured coating to hold their colour under lights.
Every step is manual, so weight, roundness and seam quality vary from ball to ball. That variation is what an inspection measures.
MCC Law 4: weight and size by ball size
| Ball (when new) | Weight | Circumference |
|---|---|---|
| Size 1 | 5.5 to 5.75 oz (156 to 163 g) | 8.81 to 9 in (22.4 to 22.9 cm) |
| Size 2 | 5 to 5.25 oz (142 to 149 g) | 8.46 to 8.66 in (21.5 to 22 cm) |
| Size 3 | 4.69 to 4.84 oz (133 to 140 g) | 8.07 to 8.27 in (20.5 to 21 cm) |
Law 4.6 leaves the choice of size to the governing body for the match. The current Law names sizes 1, 2 and 3, so make sure your carton and ball markings use the same terms as the competitions you sell into. A ball that is legal in weight but marked with the wrong size is still a rejected ball for a club that buys by size.
What we check on cricket balls
| Check | How it is checked | What fails |
|---|---|---|
| Weight | Every sampled ball on a calibrated scale reading to 0.1 g | Outside the Law 4 range for the size, or the tighter range in your order |
| Circumference and roundness | Circumference tape or ring gauges, measured across the seam and at right angles to it | Outside the range; a difference between planes beyond your tolerance (an egg-shaped ball) |
| Main seam | Rows of stitches counted, stitch spacing and seam height checked against the sample | Missing rows, broken or loose stitches, flat or uneven seam |
| Quarter seams | Fit of the quarters and the closed internal seam | Gaps, steps between quarters, quarter seam opening |
| Colour and coating | Shade against the master ball in daylight; coating rubbed with a white cloth | Shade outside the approved range, coating peeling, dye rubbing off |
| Stamping | Brand, model, weight and size marks | Wrong size mark, smudged or missing gold stamping |
| Core (destructive, by agreement) | One reference ball cut in half | Core construction, cork or rubber content different from the sample |
Hardness and shape retention under repeated impact are machine tests. If your contract cites BS 5993, the British Standard for cricket balls, the inspector pulls and seals balls for an accredited lab rather than improvising a test on site.
Common cricket ball defects and how they are classed
| Defect | Typical cause | Class |
|---|---|---|
| Weight or circumference outside Law 4 for the marked size | Core variation, cover too thick or thin | Major |
| Main seam stitches broken or rows missing | Rushed hand stitching, weak thread | Major |
| Ball out of round | Core not centred, poor pressing | Major |
| Quarter seam gap | Poorly cut quarters | Major |
| Wrong size or weight stamped on the ball | Mixing at stamping | Major |
| Shade variation within a box | Different leather or dye lots | Minor (major for match-ball sets) |
| Smudged stamping, small coating marks | Finishing | Minor |
Market rules and packing
There is no CE or safety mark for a cricket ball itself. In the EU it falls under the General Product Safety Regulation, which asks for traceability and the manufacturer or importer's details. If the leather is chrome-tanned, the EU limit of 3 mg/kg chromium VI for leather articles that come into contact with the skin applies; see chromium VI in leather. A lab confirms it on balls the inspector seals.
Balls are packed in individual boxes, then in cartons. Damp leather grows mould in a closed box, and heat in a container can soften the coating so balls stick to their wrappers. The inspector opens boxes for mould and smell, checks that the ball in each box matches the label, and checks that silica gel or another desiccant is present if you asked for it.
What to put in your purchase order
- Ball size (1, 2 or 3) and your weight and circumference tolerance, if tighter than Law 4.
- Construction: two-piece or four-piece, core type, number of seam rows, thread.
- Colour (red, white or pink), finish and the master ball for shade.
- Stamping artwork, including the size or weight mark.
- Whether one reference ball per lot may be cut open.
- Lab tests (BS 5993 or your own) and who pays for the balls used.
- Packing: individual box, desiccant, carton count.
Balls usually ship with bats and protective gear. Book an inspection anywhere in India.
