IMDA SER vs. GER: Choosing Your Singapore Registration Route in 2026

Singapore's IMDA offers different schemes for equipment registration based on product complexity and intended use. Choosing the wrong route can lead to unnecessary delays or higher fees.

Executive Summary: SER vs. GER

SER (Simplified Equipment Registration): Self-declaration for standard mobile terminals and broadband access equipment. Faster and cheaper.
GER (General Equipment Registration): Mandatory technical review of test reports for high-interference devices (e.g., base stations, walkie-talkies). Slower and more expensive.
Validity: Both schemes typically result in certificates valid for 5 years.
Note: A third scheme, ESER, exists for low-power short-range devices like Bluetooth.

Overview of the Schemes

IMDA utilizes a practical, risk-based approach to compliance. Products that are less likely to cause interference or have simpler technical profiles can use the "Simplified" route. High-power devices that could potentially jam the local emergency services radio network are rightfully placed under the stricter "General" route. Let's be honest: explaining to the Singapore government why your industrial router knocked out a local cell tower is not a conversation you want to have.

Broadband and cellular SER route equipment

1. Simplified Equipment Registration (SER)

The SER is primarily designed for mobile terminals (like 5G/LTE smartphones) and broadband access equipment (like cable or ADSL modems).

Typical Products: 5G smartphones, broadband modems.
Process: Based on a Supplier's Declaration of Conformity (SDoC). The local dealer declares the equipment complies with IMDA standards based on existing test reports.
Speed: Fast. Often processed in 1 to 3 working days.

Industrial wireless base station GER route equipment

2. General Equipment Registration (GER)

The GER is mandatory for equipment with a high potential for radio frequency interference or devices employing highly specialized new technologies.

Typical Products: Base stations, UWB devices, land mobile radios, and certain industrial IoT gateways.
Process: Requires the submission of full technical test reports. IMDA engineers will actually read them and conduct a technical review before issuing the registration.
Speed: Slower. Typically 5 to 10 working days, though it can stretch to weeks if there are discrepancies.

Summary Table

Feature	SER	GER
Target Devices	Mobile terminals, broadband access	Base stations, UWB, walkie-talkies
Technical Review	No (Self-declared SDoC)	Yes (IMDA evaluation of test reports)
Lead Time	1-3 Working Days	5-10 Working Days
Validity	5 Years	5 Years

Frequently Asked Questions (FAQ)

What if my device has Bluetooth and Wi-Fi?

If it is a low-power short-range device (SRD) without cellular capabilities, it likely falls under ESER (Enhanced Simplified Equipment Registration), which is an even simpler self-declaration route than SER.

Can I voluntarily use the GER route for an SER product?

Yes. If your equipment qualifies for SER, you still have the option to register under the GER scheme if you want IMDA to formally evaluate your lab test reports. However, it involves higher costs and longer processing times.

Are international test reports accepted for GER?

Yes, CE (RED) or FCC test reports are generally accepted, provided they demonstrate compliance with Singapore's local IMDA technical specifications.

How HertzWeg Optimizes Your Route

Many products that qualify for ESER or SER are mistakenly submitted via GER by inexperienced brokers, leading to wasted time and resources. HertzWeg reviews your technical specifications upfront to determine the most efficient registration route, ensuring your product hits the Singapore market as quickly as possible. We pride ourselves on the fact that our paperwork usually wins.
