It is the first time a vote has been tied in the House of Commons since 2019, when MPs voted on alternative plans for Brexit.
Richard Burgon, Dawn Butler and Dame Meg Hillier were among those Labour MPs to back the UK-EU Customs Union Bill.
The majority of Labour MPs abstained on the bill, while three voted against: Jonathan Brash, Luke Myer and Josh Newbury.
Eighty-nine Conservative MPs and four members of Reform UK voted against the bill.
Liberal Democrat leader Sir Ed Davey said the vote was a “historic victory” for his party.
“The prime minister must now listen to Parliament and the public, drop his self-imposed red lines and finally go for proper growth through an ambitious trade deal with the EU,” he added.
The Speaker casts his vote according to what was done in similar circumstances in the past. Where possible the issue should remain open for further discussion and no final decision should be made by a casting vote.
