Is Hardbat Legal for Sanctioned Table Tennis Play?
The answer isn’t a flat no, it’s specifically no for the main event, and a real, organized yes for a separate one, which is easy to miss entirely if you’ve only ever heard the short, simplified version of this rule repeated secondhand.
Short answer: Sandpaper is not a covering the ITTF Laws allow, so it cannot be used in events played under those Laws. USA Table Tennis lists separate hardbat and sandpaper events at its National Championships, where these paddles are used under their own rules. A racket built from ITTF-authorised rubbers is a different matter: it is not excluded, and the sandpaper construction is what the ITTF Laws rule out.

The Core Rule: Sandpaper Doesn’t Meet Equipment Criteria
The ITTF Laws say that a side of the blade used for striking the ball shall be covered with either ordinary pimpled rubber or sandwich rubber, and the Regulations add that any such rubber shall be currently authorised by the ITTF. Sandpaper is neither, so it cannot be used in an event played under those Laws. The Statutes also say the Laws are presumed to apply to competitions unless variations are agreed in advance or made clear in the published rules of the competition.
A Specific Historical Fact: The 2012 US Rule Repeal
The hardbat.com rules page, in a section dated 12/2012, says that Rule #3.2.1.3.2, which allowed legal hardbats to also be legal in USATT rated events for the past 10+ years, was repealed in December 2012. It adds that to use a hardbat in normal USATT rated (sponge) events, you must construct it out of ITTF legal rubbers, and it must be red/black.
📊 Note: The rule number and date above come from the hardbat.com rules page. This article did not locate the current USATT tournament rulebook text on the point, so check the current USATT rules before relying on it for a specific event.
The Real Exception: Dedicated Hardbat Events Exist
The same hardbat.com section says “The rule change does not affect hardbat events.” USA Table Tennis’s page for the 2026 U.S. National Table Tennis Championships (San Jose, California, July 3 to 9, 2026) lists hardbat events, including Hardbat Men’s Singles and Hardbat Doubles, and sandpaper events, including a Sandpaper Open. A 2023 USATT news item says that in its classic events rackets must be all wood, with hardbat, sandpaper or plain wood coverings.
What Actually Makes Sandpaper Illegal, Not the Playing Style
It is worth being precise here: the exclusion is about the physical racket covering, not about a playing style. The Laws describe ordinary pimpled rubber as a single layer of non-cellular rubber with pimples outwards and a total thickness including adhesive of less than 2.05mm, and sandwich rubber as a layer of cellular rubber under pimpled rubber with a total thickness of less than 4.05mm. Either kind has to be ITTF-authorised. On colour, the Laws require one side of the blade to be matt black and the other a bright colour clearly distinguishable from black and from the colour of the ball. The hardbat.com note quoted above says red/black for a hardbat used in USATT sponge events.
💡 Pro tip: If you want to use a hardbat-style racket in a standard event, check the ITTF list of authorised rubbers and the event’s own equipment rules before you buy, because sandpaper is not an option there.
Equipment Standards for Dedicated Hardbat Events
The hardbat.com rules say a hardbat must have an all-wood blade, and each playing surface must be covered with a racket covering explicitly listed on the current Approved Hardbat Racket Coverings list. It describes a pre-assembled hardbat as factory-covered with the same pimpled rubber on both sides and no sponge. The same rules allow an unused non-playing surface to carry sandpaper, bare wood or a paint sheet. A 2023 USATT news item says its classic events allow hardbat, sandpaper or plain wood coverings on all-wood rackets. No published USATT sandpaper grit specification was found, so no grit figure is given here.
⚠️ Watch out: Each hardbat or sandpaper event sets its equipment rules through its organisers, and the hardbat.com list of approved coverings is described there as subject to change at any time. Read the event’s entry form before buying a paddle.
Why This Distinction Exists at All
The hardbat.com rules state their motivation: to define a game that approximates as closely as possible table tennis as played in the 1930s and 40s, before the advent of sponge rubber, and that balances offense and defense, minimizes mechanical advantage due to equipment variation, and fosters longer rallies than occur in sponge play.
Why Hardbat Still Has a Real Following
USATT’s own pages show these events are active. The 2026 U.S. Nationals listed Junior, 40 and over and 60 and over hardbat divisions and a U1700 hardbat event, as well as two sandpaper events. A 2023 USATT news item announced a US Hardbat and Sandpaper Championships in Westchester, NY, alongside a National Hardbat and Sandpaper Championships in Austin, TX.
How Hardbat Rules Differ
Beyond equipment, the hardbat.com rules change a few things. Games are to 21 points with the service switching every 5 points. Long pants, long-sleeved shirts, warmup suits, hats and visors are permitted. Balls may be 38mm, 40mm or 40+ plastic at the organiser’s discretion. The rules of play are otherwise the same as USATT’s.
How Sponge Rubber Changed the Sport in the First Place
The hardbat.com rules describe hardbat as approximating the game as played in the 1930s and 40s, before sponge rubber. Their stated aims also include minimizing deception to players caused by easily-produced intense spin and lessening the importance of serve and service return compared to sponge play. Scoring is not identical: hardbat games are to 21 points.
Checking Before You Show Up With Hardbat Equipment
Given the real difference between standard and hardbat-specific events, it’s worth explicitly confirming which ruleset a given tournament or league actually follows before assuming your equipment is compliant, rather than discovering a problem during equipment inspection on the day of the event. A tournament’s entry materials or a direct question to the organizer beforehand resolves this far more cleanly than an unpleasant surprise at check-in, especially if you’ve traveled specifically to compete.
💡 Pro tip: If a tournament listing doesn’t explicitly say “hardbat” or “sandpaper” in its event name or description, assume it’s a standard sponge-rules event and confirm directly with the organizer if you have any doubt at all.
What This Means If You’re Curious About Trying Hardbat
If hardbat or sandpaper play interests you, look for a dedicated hardbat or sandpaper event or a club that runs hardbat sessions, rather than assuming you can bring sandpaper equipment to a standard tournament. In the United States, USATT’s news and event pages list its hardbat and sandpaper events, so they are a sensible place to start.
- ✓Check for dedicated hardbat or sandpaper events through your national association if you want to compete with that equipment
- ✓Check the ITTF list of authorised rubbers before building a hardbat-style racket for a standard event
- ✓Confirm current equipment rules directly with a tournament organizer before assuming either way
- ✓Treat the 2012 US repeal as historical context, not a currently active rule
- ✕Assume sandpaper is legal in any standard, non-hardbat-specific sanctioned event
- ✕Confuse the sandpaper construction ban with a ban on flatter, less spin-dependent playing styles generally
- ✕Assume hardbat has no legitimate organized competitive scene at all
- ✕Assume a hardbat paddle is accepted at an event without checking the Approved Hardbat Racket Coverings list
A Related Question: What About Homemade or Novelty Paddles?
The same principle extends to any homemade, novelty or otherwise non-ITTF-approved racket covering. Under the ITTF Laws, a striking side must be covered with ordinary pimpled rubber or sandwich rubber within the stated thickness limits, any such rubber must be currently authorised by the ITTF, and the covering must be used without any physical, chemical or other treatment. In an event played under those Laws, a covering that does not meet them cannot be used, whether it is sandpaper, an unusual thickness or something improvised.
A Note for Coaches Working With Junior Players
If a junior player expresses interest in hardbat, whether from watching older footage, hearing about it from a coach, or simply trying an old paddle they found, it’s a reasonable opportunity to explain this exact distinction directly rather than leaving them with a vague sense that hardbat is either universally banned or universally allowed. Framing it accurately, a real, separate competitive format with its own legitimate events, rather than either a forbidden relic or a casual toy, gives a young player an accurate picture of where it actually fits in the sport’s broader structure.
The Short Version, Restated
Sandpaper is not a covering the ITTF Laws allow, so it cannot be used in events played under those Laws. The hardbat.com rules page says a USATT rule letting hardbats be used in USATT rated events was repealed in December 2012. USATT lists hardbat and sandpaper events at its National Championships. Racket coverings that meet the ITTF Laws and are ITTF-authorised remain acceptable under those Laws.
