For a Non-Prescribed Product, which includes: plugs, adaptors, extension units, lamp holders, flexible cords, and unvented thermal storage type electric water heaters, the following are accepted as a certificate of safety compliance:
- A declaration of conformity issued by a 'recognised manufacturer';
- A certificate or test report issued by a 'recognised certification body' (RCB) under registration of EMSD in one of the following: CB test certificates issued by National Certification Bodies participating in the CB Scheme; Endorsed certificates or test reports issued by organisations accredited by the Hong Kong laboratory Accreditation Scheme (HOKLAS) or by the Hong Kong Accreditation Service (HKAS); Endorsed certificates or test reports issued by organisations that have been accredited by those bodies which have mutual recognition agreements with HOKLAS or HKAS.
For a Non-Prescribed Product (i.e., all other electrical products), in addition to the two types of documents stated above, a declaration of conformity (DOC) issued by the product manufacturer will also be accepted as a certificate of safety compliance. Non-prescribed products must comply with the Hong Kong Essential Requirements, which are presumed to be fulfilled if the product complies with relevant IEC standards.

Hong Kong is a free port, meaning no tariffs are charged on the import or export of goods. Therefore, there is no need to implement a de minimis threshold.

According to Section 9 of the Telecommunications Ordinance, any person who wishes to import into Hong Kong any radio transmitting apparatus needs to obtain a permit granted by the Communications Authority, unless holding an unrestricted radio dealer's license.

Hong Kong lacks a comprehensive framework for the protection of trade secrets. However, confidential information, including trade secrets, is protected by the common law of confidence, as well as by express and implied contract terms. While there is no single definition of a trade secret in Hong Kong, the characteristics of a trade secret were summarised in the 2003 case of AXA China Region Insurance Co Ltd v. Pacific Century Insurance Co Ltd, namely that a trade secret or its equivalent must be information which: is used in a trade or business; is confidential, i.e. is not already in the public domain; can be easily isolated from other information which an employee is free to use; if disclosed to a competitor, would be liable to cause real or significant harm to the owner; and is restricted from dissemination by the owner of the information. In the case of infringement, court orders may include (i) a declaration as to the confidentiality and the (lack of) entitlement to the use of the information; (ii) an injunction to restrain the use or further use of the confidential information; (iii) disclosure of any infringing use made of the information; and (iv) delivery of any infringing materials damages or, at the Plaintiff’s election, an account of profits.

There is no obligation for passive infrastructure sharing in Hong Kong to deliver telecom services to end users. However, it is practised in both the mobile and fixed sectors based on commercial agreements.

Hong Kong does not mandate functional separation for operators with significant market power (SMP) in the telecom market. However, it is reported that major fixed and mobile carriers are subject to accounting separation requirements to assist the Authority in monitoring developments in the telecommunications industry. Section 7A of the Telecommunications Ordinance (Cap. 106) empowers the Authority to attach special conditions to carrier licences, enabling it to impose and enforce service-level accounting separation requirements through licence conditions and related directions.
It is further reported that the Office of the Communications Authority (OFCA) requires dominant operators to maintain and report accounts disaggregated by service segment within their licensed operations, whereas non-dominant operators are required to maintain and report accounts only for their licensed operations as a whole.

Hong Kong has appended the World Trade Organization (WTO) Telecom Reference Paper to its schedule of commitments.

It is reported that the Office of the Communications Authority (OFCA), the executive authority for the supervision and administration of services in the telecommunications sector, is independent from the government in the decision-making process.

Section 374 of the Companies Ordinance requires a company to maintain its accounting records either at its registered office or at another location determined by the directors, ensuring that they remain accessible to the directors at all times without charge. Where such records are kept outside Hong Kong, the corresponding accounts and returns relating to the business concerned must be sent to, and preserved at, a place within Hong Kong for the same purpose. Under section 2, company refers to an entity formed and registered under the Ordinance, an existing company, or a re‑domiciled company.
