Trade Department warns retailers to comply with pricing law

The Department of Internal Trade has reminded shop operators to strictly comply with the Price of Goods and Services Act BE 2542 (1999), as part of efforts to maintain a transparent and fair trading environment.

The department said traders must follow key legal requirements on price displays, pricing practices and stockholding, warning that violations could result in fines, imprisonment or both.

Clear price display required

Under Section 28 of the law, sellers are required to clearly display the prices of goods and services so that consumers can easily see them.

Retailers must also sell products at the prices shown on the labels. If there are any additional charges beyond the listed price, these must also be clearly stated.

Violations of this section carry a fine of up to 10,000 baht.

Overcharging and market manipulation banned

Under Section 29, sellers are prohibited from charging unreasonably high prices or taking any action that causes disruption to market prices.

The law is intended to prevent businesses from taking advantage of consumers through unfair pricing practices.

Breaches of this section are punishable by up to seven years in prison, a fine of up to 140,000 baht, or both.
