Is it Against the Rules to Apply Handball Resin to the Ball?

While watching a video about handball, a question arose: is it against the rules to apply handball resin to the ball?

Handball resin is a substance used by players to improve their grip on the ball. However, the rules of handball do not explicitly mention the use of resin. According to the International Handball Federation (IHF), the ball must meet certain standards, but there is no mention of resin or any other substance being applied to the ball.

It is worth noting that some handball players use resin to improve their grip, especially in situations where the ball is slippery or wet. However, it is not clear whether this practice is allowed under the rules of the game.

Further clarification on this matter would be necessary to determine whether applying handball resin to the ball is indeed against the rules.
