Pursuant to Art. 47, an intermediary or an internet service provider who provides a conduit is not liable for the content of electronic records that indicate a likelihood of civil or criminal liability if the intermediary or internet service provider: (i) had no actual knowledge of such information; or (ii) on acquiring actual knowledge or becoming aware of such facts, followed the takedown procedures required by the Regulations as soon as possible.

It is reported that Saint Lucia imposes an identity requirement for SIM registration. Anyone wanting to purchase a SIM card has to provide their national ID card or a passport in the case of foreigners, to activate a new prepaid SIM card.

According to Section 47 of the Data Protection Act, any individual or company that seeks to collect, transfer, or process personal data must have a certification as a data controller. The data controller is the representative in charge of processing personal data and must make an application for registration to the Commissioner. The Commissioner can reject the license if it reasonably believes that (a) the particulars proposed for inclusion in an entry in the register are insufficient or any other information required by the Commissioner either has not been furnished or is insufficient; (b) appropriate safeguards for the protection of the privacy of the data subjects concerned are not being, or will not continue to be, provided by the data controller; or (c) the person applying for registration is not fit and proper in the determination of the Commissioner.

Under Cabinet Conclusion No. 645 of 1984 on the Areas of Investment Activity Reserved for Nationals, the importation of goods for the purpose of trading is, in principle, reserved for Saint Lucian nationals. In operational terms, Sections 3, 5 and 6 of the Trade Licences Act require non-exempt foreign persons and companies to obtain an annual trade licence, issued with the approval of the Minister, before engaging in trade or selling goods in Saint Lucia. Since March 2006, nationals and qualifying companies of CARICOM and OECS Member States have been exempt from this requirement. The authorities report that the Cabinet reservation is not always applied, including in cases involving large investments or where local investors lack commercial interest or the required technology, and a trade licence may be granted to a non-national investor in such circumstances.

Pursuant to Schedule 3 of the Customs (Management and Control) Act, the importation of radio and television transmitting equipment is prohibited unless authorised under a licence issued by the Minister of Communications.

According to Art. 4 of the Statutory Instrument 10/2002, the equipment mentioned in Art. 4.2 must receive a type approval certificate from the regulatory authority. This includes cellular telephones, cordless telephones, fax machines, GSM machines, mobile radios, modems, wireless remote devices, PABXs, pagers, radio receivers and transmitters, satellite earth stations, telecommunications switching equipment, telephone instruments, telex equipment, other equipment emitting a radio signal and any other customer premise equipment to be attached to any part of a licensed telecommunications network.
According to the Caribbean Cooperation for Accreditation (CCA) standards, foreign businesses must pass an accreditation by accredited laboratories that have Mutual Recognition Agreements (MRAs) with counterpart bodies. Test results from accredited laboratories, which are parties to a given MRA, are automatically accepted. The CCA is based on principles of cooperation and collaboration among the recognised National Accreditation Bodies (NABs).

Since April 2021, electronic-money accounts have been subject to limits directly affecting online payments. Under Guideline 6 and Schedule 1 of the Electronic Money Guidance Notes, Level 1 accounts held by natural persons are subject to a monthly limit of XCD 15,500 (approx. USD 5,741) and a per-transfer or per-purchase limit of XCD 2,700 (approx. USD 1,000). Level 2 accounts held by legal persons are subject to a monthly limit of XCD 25,000 (approx. USD 9,259), an account-balance limit of XCD 15,500 (approx. USD 5,741), and a per-transfer or per-purchase limit of XCD 2,700 (approx. USD 1,000). Accounts operated through other sub-agents, whether held by natural or legal persons, are subject to monthly, account-balance and per-transfer or per-purchase limits of XCD 2,700 (approx. USD 1,000). These limits apply to both person-to-person (P2P) transfers and business-to-consumer (B2C) payments, and therefore directly restrict the use of electronic-money accounts for online purchases.

Saint Lucia does not implement any de minimis threshold, which is the minimum value of goods below which customs do not charge duties.
