Tender committees rarely disqualify a panel over its quality. What sinks a bid is paperwork: a local content value nobody can verify, an expired certificate, or a figure copied from a brochure instead of the official database. If you are bidding wall, partition, or ceiling panels on a government or state-owned project in Indonesia, settle this part first.
This guide covers what changed under Perpres 46/2025 and Permenperin 35/2025, the TKDN values actually recorded for sandwich panels in Indonesia, and how price preference shifts your bid position. Every figure is attributed in the text, including the parts that remain unconfirmed.
Why TKDN Decides the Outcome of a Bid
TKDN, or Tingkat Komponen Dalam Negeri, is Indonesia's local content level. The policy is not new: Law 3/2014 on Industry sets the obligation to use domestic products in Articles 85 to 89, elaborated through Government Regulation 29/2018 and the P3DN programme. What changed in 2025 is how firmly it is applied.
According to ANTARA's reporting on Perpres 46/2025, the second amendment to Perpres 16/2018 on Government Procurement of Goods and Services, central government, regional government, and state-owned enterprises are required to buy products carrying TKDN and to prioritise them over imports. In practice the local content value moves from a bonus to an entry requirement.
Spending Priority and Price Preference
Procurement briefing material sets out Article 66 of Perpres 46/2025 as a three-step order. Where products exist whose TKDN plus Company Benefit Weight (BMP) exceeds 40 percent, products above 25 percent TKDN are bought first. If none exist, products with at least 25 percent TKDN still take priority. Only when both tiers are empty may alternatives be considered.
Price preference sits in the following article. For goods and other services it runs to a maximum of 25 percent, and only products with at least 25 percent TKDN qualify, through tender or e-purchasing mini competition. Procurement training summaries add one practical limit: the preference applies only when the package ceiling price reaches at least IDR 1 billion.
Secondary sources disagree on whether these provisions sit in Article 66 or 67, so check the article number against the official JDIH copy before quoting it. The 25 percent figure and the IDR 1 billion floor appear consistently across sources.
The effect is real. On a package with a ceiling of IDR 5 billion, a 25 percent preference makes a certified bid of IDR 4.8 billion evaluate far below an uncertified rival. A ten percent price gap often loses to a certificate gap.
What TKDN Values Do Sandwich Panels Actually Carry?
This question gets guessed at more than it gets answered. Only one answer holds up: open the product certificate in the Ministry of Industry TKDN database. Several certificates recorded there give a realistic range.
- Pre-insulated sandwich panel: TKDN of 44.75 percent on a 2022 certificate verified by PT Surveyor Indonesia, covering thicknesses up to 150 mm.
- Insulated wall or sandwich panel: 39.88 percent on a certificate issued in 2021.
- Panel certificates issued in 2025: 39.69 percent for EPS cores and 35.88 percent for rock wool cores, valid for three years from 19 September 2025.
So locally made sandwich panels generally sit above 35 percent, clear of the 25 percent threshold. But the number belongs to one product from one plant, not to the category: EPS panels from two factories can be a dozen points apart.
One point we could not confirm: we found no TKDN percentage threshold set specifically for the sandwich panel category. The general 25 percent procurement threshold applies, while the minimum for each package is stated in the tender announcement. Do not rely on a number that is not written in that document.

Certification: What Permenperin 35/2025 Changed
Permenperin 35/2025 on the provisions and procedures for TKDN and BMP certification revokes Permenperin 16/2011, the rule in force for nearly fifteen years, along with Permenperin 46/2022. Secondary sources describe a three-month transition with an effective date around 11 to 12 December 2025; the exact date should be checked against the official copy on peraturan.bpk.go.id.
The changes applicants feel most:
- The calculation method moves from detailed cost accounting to weighting.
- Supplier tracing stops at Tier 1 rather than Tier 3.
- Certificate validity is reported to extend from three years to five.
- Verification by an Independent Verification Body is cut from 22 working days to 10.
- Certificates and TKDN statements are issued electronically through SIINas.
Kusuma Law Firm notes a point that matters to project owners: certificates issued under the old rule stay valid until their own expiry date. A 2022 certificate showing 44.75 percent is not voided by the new regulation.
Document Checklist Before You Submit
From the supplier side, these five items draw the most committee findings:
- The TKDN certificate number and its expiry date, checked against the Ministry database rather than a brochure.
- Agreement between the product name on the certificate and the panel specified, including core type and thickness range.
- The BMP value, where the package requires TKDN plus BMP above 40 percent.
- A declaration of domestic product use, commonly requested in tender documents.
- Supporting technical data such as fire reaction class, U-value, and metal coating thickness. We explain how to read these in our guide to panel certificates and datasheets.
One specification point often written wrongly into bills of quantity: our panel line covers walls, partitions, and room ceilings at thicknesses of 50 to 150 mm across every core type, whether PU, PIR, EPS, or rock wool. Figures outside that range make it hard to match the delivered product to a certificate.
After the Award, Handle Building Compliance
TKDN governs where the product comes from. Building fitness is handled separately through PBG and SLF, and those timelines often collide with handover deadlines. We cover the requirements, process, and cost range in our article on SLF for sandwich panel buildings.
Frequently asked questions
Is a TKDN certificate mandatory to join a government tender?
The obligation sits with the buyer: Perpres 46/2025 requires agencies and state-owned enterprises to prioritise products carrying TKDN. For suppliers, a package that sets a minimum TKDN will reject bids without a valid certificate. Read the package announcement, because requirements differ.
What TKDN value is safe for a tender?
The general procurement threshold is 25 percent. Panel certificates recorded in the Ministry database generally sit above 35 percent, so locally made panels usually clear it. Still match your figure against the minimum written in the package document, not against a market average.
How long does TKDN certification take now?
Under Permenperin 35/2025, verification by an Independent Verification Body is reported to fall from 22 working days to 10, with certificates issued electronically through SIINas. For small industry, the free self-declare route proceeds after validation by the Directorate General team.
Prepare the TKDN Documents for Your Project
If you are drafting specifications, a bill of quantities, or a bid that includes wall panels, partitions, or room ceilings, we can align the specification with certificates that genuinely exist, together with the supporting technical data. Tell us what the project needs and request a quotation through the sandwichpanels.id contact page, noting room type, wall area, and your tender deadline so the quotation arrives ready to attach.
