Basketballs have come a long way since Dr. James Naismith invented the game in 1891. The first basketball was manufactured in 1894 and was made of laced leather. Today, basketballs are made from leather, rubber, nylon, and other synthetic materials. They are produced by several companies, including Spalding and Wilson, which operate across a global network of suppliers, manufacturers, distributors, and retailers. Spalding, an American sports equipment manufacturing company, has had exclusive rights to make NBA basketballs since 1983. The company was founded by Albert Spalding in Chicago in 1876 as a baseball manufacturer and is currently headquartered in Bowling Green, Kentucky. Wilson, on the other hand, manufactures its basketballs in China, viewing the country as the league's most lucrative foreign market.

What You'll Learn
History of basketballs
The game of basketball was invented in 1891 by Dr. James Naismith, who hung two half-bushel peach baskets at opposite ends of a gymnasium and set out 13 rules for his students at the International Training School of the Young Men's Christian Association (YMCA) in Springfield, Massachusetts. From 1891 to 1893, a soccer ball was used to play the game. The first basketball was manufactured in 1894 by Spalding, which based its design on that of a baseball. This first basketball was made of laced leather and was about four inches larger than a soccer ball in circumference. Spalding has had exclusive rights to make NBA basketballs since 1983.
In 2006, the NBA briefly tried to implement polyurethane leather basketballs. The composite material was less expensive to produce than real leather balls and was viewed by the sporting goods industry as the next big thing. However, the new feel and the difference in rebound height led the NBA Players Association to file two unfair labor practice charges with the National Labor Relations Board, and the NBA quickly reverted to using real leather balls.
Horween Leather Company, one of the oldest leather tanneries in the United States, supplies leather for basketballs. The company receives about 3,000 cowhides per week, mainly from slaughterhouses in Iowa and Ontario, Canada. The hides undergo a three-week process of hair removal, tanning, embossing, finishing for colour, durability, and feel, and finally drying. Each basketball takes about three to four square feet of leather. Several times a year, large quantities of leather are shipped to a manufacturing facility in China, where the balls are assembled. The inner sphere of the ball is covered with rubber from Malaysia and Vietnam, and the outside of the inflated bladder is made of nylon winding from Japan, adding structural integrity and durability.
In May 2020, the NBA announced that Wilson would be the official game ball starting in the 2021-2022 season, the league's 75th anniversary. Wilson's basketballs are made in China, which the company and the NBA view as the league's most lucrative foreign market.

Basketball design and materials
The modern basketball is composed of several materials, including leather, nylon, rubber, and bladder. The leather used for basketballs undergoes a three-week process of hair removal, tanning, embossing, finishing for colour, durability, and feel, and finally drying. Each basketball requires about three to four square feet of leather. The leather is sourced from Horween Leather Company, one of the oldest leather tanneries in the United States, which receives cowhides from slaughterhouses in Iowa and Ontario, Canada.
Inside each basketball, nylon winding from Japan forms the outer layer of an inflated bladder, providing structural integrity and durability. The bladder is the balloon-like structure that holds air. The inner sphere of the ball is covered with rubber sourced from Malaysia and Vietnam.
After assembly, the basketballs are shipped to Alexander City, Alabama, for a rigorous testing process. The balls must pass diameter, weight, and rebound checks to ensure they meet the standards for NBA gameplay. The NBA ball must be inflated between 7.5 and 8.5 ounces per square inch, and when dropped from six feet, it should bounce between 52 and 56 inches high.
In 2006, the NBA briefly experimented with polyurethane leather basketballs, but the new material was not well-received by players due to its different feel and rebound height. As a result, the NBA returned to using real leather balls. The contract for the official game ball was later awarded to Wilson, starting in the 2021-2022 season. Wilson manufactures its basketballs in China, recognising the country as the league's most lucrative foreign market.

Manufacturing process
The manufacturing process of basketballs has evolved since the first basketball was manufactured in 1894. Made of laced leather, the first basketball was about four inches larger than a soccer ball in circumference. Today, basketballs are made from a variety of materials and are assembled in different parts of the world.
Horween Leather Company, one of the oldest leather tanneries in the United States, supplies leather for basketballs. The company receives about 3,000 cowhides per week, primarily from slaughterhouses in Iowa and Ontario, Canada. The hides undergo a three-week process of hair removal, tanning, embossing, finishing for colour, durability, and feel, and finally drying. A 1,000-ton press with German-made embossing plates gives the leather its distinctive pebbling. Each basketball requires about three to four square feet of leather.
Once the leather is ready, it is shipped to a manufacturing facility in China. Inside each basketball is a nylon winding from Japan that forms the outer layer of an inflated bladder, providing structural integrity and durability. The inner sphere of the ball is covered with rubber from Malaysia and Vietnam.
After assembly, the basketballs undergo a rigorous testing process to ensure they meet the required standards. The balls are shipped to Alexander City, Alabama, where they undergo a three- to four-week testing process, including diameter, weight, and rebound checks. The NBA ball, for example, must be inflated between 7.5 and 8.5 ounces per square inch. When dropped from six feet, the basketball should bounce between 52 and 56 inches high.
Once the basketballs pass the quality assurance testing, they are delivered to the teams and are ready for play. The manufacturing process ensures that the basketballs not only look good but also perform well and feel good to the players.

Testing and quality control
Basketballs are made from materials sourced from around the world, including leather from the US, nylon from Japan, rubber from Malaysia and Vietnam, and assembly in China. The official NBA basketball, produced by Spalding, is the result of a complex supply chain that spans North America, Japan, China, Malaysia, and Vietnam.
Once the basketballs are assembled, they are shipped to Alexander City, Alabama, for a rigorous testing and quality control process. This stage ensures that the balls meet the exacting standards of the NBA and are fit for professional play. The testing process typically lasts three to four weeks, during which the balls undergo a series of checks and assessments.
One of the critical tests is the diameter check, which ensures that the balls fall within the specified size range for NBA regulations. The weight of the balls is also carefully measured and verified to meet the required standard. However, the most distinctive test is the rebound check, which assesses the ball's bounce. The NBA mandates that the official game ball, when inflated to between 7.5 and 8.5 ounces per square inch and dropped from a height of six feet, should bounce back to a height of 52 to 56 inches. This test is crucial because it directly impacts the performance and playability of the ball during a game.
In addition to these physical tests, the balls also undergo quality assurance checks to ensure they meet aesthetic standards and provide a good "feel." This holistic approach to testing and quality control guarantees that the basketballs are not only functional but also meet the high standards expected by players and fans alike.
Spalding, the company with exclusive rights to manufacture NBA basketballs since 1983, understands the importance of this process. They rely on meticulous quality control to ensure consistency and performance in every ball that bears their name. This commitment to excellence has made Spalding a trusted brand in the world of basketball and a key partner in the sport's global appeal.
