Why Is the Subcontracting Scheme a Vital Operational Strategy for PMA Factories in SEZs?
Subcontracting is a crucial manufacturing flexibility solution for Foreign Direct Investment (Penanaman Modal Asing / PMA) factories operating in Special Economic Zones (SEZ/KEK). This scheme allows SEZ Business Entities (Pelaku Usaha KEK) to temporarily transfer a portion of raw materials or semi-finished goods (Work-in-Process / WIP) to partner factories outside the zone—either to companies in the Local Market / Domestic Tariff Area (Tempat Lain Dalam Daerah Pabean / TLDDP) or other Bonded Zones (Kawasan Berikat)—to undergo specific further processing before being returned to the SEZ factory.
This operational measure is typically taken when an SEZ factory faces temporary machinery capacity constraints, lacks specialized equipment (such as heat treatment, electroplating, or specific laboratory testing), or experiences sudden production order surges. The Indonesian Government provides legal certainty for these activities under Ministry of Finance Regulation (PMK) No. 33/PMK.010/2021 on Tax, Customs, and Excise Treatments in Special Economic Zones.
Despite this operational flexibility, transferring facility-benefited raw materials outside an SEZ for subcontracting carries high customs compliance risks. Without official permits, adequate customs guarantee coverage, and accurate IT Inventory tracking, outbound material movements can be classified as illegal local sales, resulting in Import Duty liabilities and severe administrative penalties.
What Are the Legal Requirements & Mandatory Criteria for Subcontracting Applications in SEZs?
The government permits subcontracting provided that the activity does not strip the primary industrial identity of the enterprise concerned and does not relocate the entirety of the manufacturing process outside the zone.
As detailed in the customs treatment and SEZ supervision provisions on the Ortax Data Center, key legal and technical requirements that SEZ Business Entities must fulfill include:
- Subcontracting Approval from the Supervising Customs Office (KPPBC): Obtaining written authorization from the Head of the local Customs Service Office prior to physically moving goods out of the SEZ area.
- Cooperation Agreement (Subcontract Contract): Executing an official business contract between the SEZ Business Entity and the Subcontractor that details processing specifications, processing timelines, and goods return obligations.
- Submission of Customs Guarantees: Furnishing a Financial Guarantee (such as a Bank Guarantee, Customs Bond, or Corporate Guarantee) covering 100% of the outstanding Import Duty and Import Taxes (PDRI) on outbound goods.
- Subcontracting Module Availability in IT Inventory: The company’s IT Inventory system must be capable of recording outbound stock movements (subcontract out) and returned processed goods (subcontract in) with complete transparency.
5 Procedural Steps for Executing Raw Material Subcontracting in SEZs
Navigating subcontracting procedures requires an integrated administrative workflow across compliance teams, logistics personnel, and electronic customs systems.
Referring to the supervision and services guidelines of the Directorate General of Customs and Excise, here are the 5 operational steps for executing subcontracting from an SEZ:
- Submitting a Subcontracting Application: The Business Entity submits a written request to the supervising Customs Service Office, attaching Bill of Materials (BOM) conversion formulas, draft subcontracting contracts, and estimated processing timelines.
- Setting & Submitting Customs Guarantees: Upon application approval, the company submits a customs guarantee equal to state tax and duty rights for raw materials temporarily exported to TLDDP.
- Filing Outbound Temporary PPKEK Customs Declarations: Draft and register the SEZ Outbound Temporary Customs Declaration (PPKEK Subkontrak) via the SINSW portal connected to CEISA 4.0.
- Physical Inspection & Outbound Cargo Release: Customs Officers verify item quantities and physical conditions at the warehouse exit gate before dispatching cargo to the subcontractor facility.
- Re-importation (Return) & Guarantee Release: Upon process completion, goods must be returned to the SEZ factory accompanied by inbound registration documents. Customs guarantees will be released once all raw material quantities and processed products are accounted for.
Comparison: Subcontracting to TLDDP Recipients vs. Inter-Facility Zone Recipients (SEZ/Bonded Zone)
| Evaluation Parameter | Subcontracting to Local (TLDDP) Companies | Subcontracting to Other SEZ / Bonded Zone Companies |
| Guarantee Obligation | Mandatory customs guarantee (100% Import Duty & PDRI) | Exempt from guarantees / uses zone facility guarantee mechanisms |
| Taxable Services (JKP) VAT | Subcontracting services VAT follows general tax rules | Subcontracting services VAT receives “Uncollected VAT” facilities |
| Processing Time Limit | Maximum 60 to 90 days (extendable with KPPBC approval) | As agreed in contract & approved by Customs |
| Document Recording | Uses TLDDP Outbound / Inbound Return Documents | Uses Inter-Zone Customs Transfer Documents |
| Audit Risk Level | High (risk of material leakage into domestic market) | Moderate (inter-zone under direct Customs oversight) |
Subcontracting Balance Control Using Host-to-Host IT Inventory BZone
Managing the circulation of raw materials moving in and out of SEZ boundaries for subcontracting requires high-precision recording to avoid stock balance audit findings.
As explained in the SEZ IT Inventory Prune technical implementation guide, logistics systems that fail to track remaining raw material balances at subcontractor sites are the leading cause of return delays that trigger guarantee liquidations.
Category A Host-to-Host (H2H) IT Inventory applications such as BZone feature a dedicated Subcontracting Ledger module. BZone segregates internal inventory balances from goods situated at vendor sites (Vendor Stock) in real-time. The system links Purchase Order Subcontracting modules from the company ERP directly to CEISA 4.0, monitors processing deadline aging schedules, and ensures complete compliance with PER-24/BC/2023 standards.
FAQ: Manufacturing Subcontracting in SEZs
What is the maximum time limit SEZ raw materials can remain at an external subcontractor factory?
Subcontracting processing periods are generally granted for a maximum of 60 (sixty) days from the outbound date. However, this period can be extended with formal approval from the Head of the supervising Customs Service Office (KPPBC) if valid technical constraints exist.
Are SEZ factories allowed to subcontract their entire manufacturing process to external parties?
No. Subcontracting is only permitted for a portion of the overall manufacturing process. Core processing or final assembly operations must remain within the SEZ Business Entity’s own factory premises.
What happens if the subcontracting time limit expires before goods are returned to the SEZ?
If the deadline passes without an official extension request, the customs guarantee submitted by the SEZ Business Entity will be immediately liquidated by the Customs Office to settle outstanding Import Duty and PDRI liabilities.
Must residual components/scrap generated during TLDDP subcontracting be returned to the SEZ?
Yes. All remaining raw materials or scrap resulting from subcontracting processes at the subcontractor location must be returned to the SEZ factory or have their state financial liabilities settled pursuant to applicable tax and customs regulations.
