Case Study｜Declined Twice? What Your DJID Inquiry Might Be Missing

The Overlooked Documentation Gap

A DJID inquiry getting declined once is frustrating. Getting declined back to back, on the same product, is usually a sign that something structural is being missed. It’s typically not a technical failure, but a documentation gap nobody flagged before submission. DJID type approval inquiries can be more complex than they appear when this requirement isn’t known upfront.

Recently, The One-GDC encountered this exact issue while handling a DJID inquiry for a product using multiple frequency ranges, WLAN and Bluetooth, simultaneously. The inquiry was declined repeatedly, and the cause wasn’t the product’s compliance itself, but a missing document that most applicants don’t anticipate.

It’s Not Just About Passing the Test

Products with WLAN capability require the local importer to submit an additional declaration letter, a sealed statement confirming which specific frequency range the product will use once it enters the Indonesian market.

Without this letter, the inquiry stalls, even if the technical test results themselves are fully compliant.

This isn’t the only reason inquiries get declined. In other cases we’ve handled, submissions were rejected due to a mismatch between the technical codes written in the RF summary statement, a separate issue worth covering in its own case study.

For products combining WLAN and Bluetooth or other capabilities, the missing declaration letter was the deciding factor between a smooth approval and a repeated back and forth cycle.

Our Approach｜Anticipating the Paperwork Before It Becomes a Problem

Once we identified that the product’s frequency profile triggered the WLAN declaration letter requirement, the rest of the process became about coordination rather than technical troubleshooting.

Our filing sequence for this case:

Technical Report Review
→ Frequency Range Identification (WLAN / Bluetooth/Wifi)
→ Additional Documentation Mapping (Declaration Letter Requirement)
→ Local Importer Coordination
→ DJID Submission
→ Approval

This meant the declaration letter was prepared and ready before submission, instead of being requested (and delaying the process) after an initial decline.

What Our Experts Have Done When It Comes to DJID

In practice, DJID inquiries often take longer than expected because of this exact back and forth over missing documents. From more than 40+ DJID cases that we have done in 2026, our technical team has learned to anticipate these moments in advance, reading through the reports upfront to confirm every required document is already in place.

Because we operate through our own Indonesian branch, we communicate directly with the local importer to make sure they’re informed of any additional documents required from their end, before submission rather than after a decline.

For us, the value of Global Market Access isn’t just knowing that a declaration letter is needed. It’s knowing which perks and technical codes apply to your specific product, and making sure the right party has the right document at the right stage of the process.

Key Takeaway

For products that has WLAN, the deciding factor in a clean DJID approval is often not just the test results. It’s whether the local importer has submitted the additional declaration letter confirming the product’s frequency range use in Indonesia.

Rather than treating DJID as a single technical checkpoint, the real path is:

1. Frequency Range Identification
2. Additional Declaration Letter
3. Local Importer Coordination

Through direct coordination with our Indonesian branch and experience across 40+ DJID cases, The One-GDC helps manufacturers avoid the repeated decline cycle and move straight to approval.
