Türkiye – Import Inspection of Environmentally Controlled Chemicals

Regulatory Scope – Prohibition, Control and Conditional Access

The Communiqué, published in the Official Gazette dated 31 December 2025, governs the importation of environmentally controlled chemicals across multiple customs regimes, including free circulation, inward processing, temporary importation, and processing under customs control.

The regulatory structure is divided into three main categories:

• Ozone-depleting substances (OTİM) and products containing or operating with such substances
• Fluorinated greenhouse gases (HFCs) and related mixtures
• Restricted and prohibited chemicals listed under specific annexes

Each category operates under a different regulatory model, meaning that a single classification error can shift a transaction from a permitted import to a prohibited one.

Because of this, correct tariff classification and technical identification must be established in advance through HS code classification advisory.

How the System Works – Category-Based Control Logic

The most critical aspect of this Communiqué is that it applies a category-based control system rather than a uniform approval process.

For ozone-depleting substances, the general rule is prohibition, with only very limited exceptions for laboratory use, essential use, or specific critical applications, all requiring explicit Ministry approval.

For HFCs, the system is built on quota-based licensing managed through the FARAVET system, where import capacity is limited by annual national quotas and controlled through electronic documentation integrated into the Single Window System.

For other restricted chemicals, the default rule is again prohibition, with limited exceptions for scientific or regulatory purposes, subject to strict documentation requirements.

This layered system means that compliance is not about obtaining a single document, but about selecting and correctly applying the appropriate regulatory pathway.

Practical Impact – Commercial Planning Is Directly Constrained

From an operational perspective, this regulation introduces constraints that directly affect commercial planning, procurement strategies, and supplier relationships.

One of the most significant impacts is the dependency on annual quota availability for HFC imports, which means that even commercially viable transactions may not be executable if quota limits are reached.

Additionally, the requirement that many approvals must be completed before export clearance in the exporting country creates a reverse dependency where Turkish regulatory compliance affects upstream logistics.

Certificates are:

• Invoice-specific
• Non-transferable
• Valid only within the calendar year

This eliminates flexibility in shipment structuring and prevents the reuse of approvals across transactions.

Where chemical inputs are linked to broader production or inward processing activities, companies must ensure alignment with inward processing compliance strategies.

Risk Areas – Where Most Compliance Failures Occur

In practice, the highest-risk areas under this Communiqué arise from front-end misalignment rather than regulatory misunderstanding.

The most common failures include:

• Incorrect categorization of chemicals between OTİM, HFC, and restricted lists
• Misidentification of whether goods contain or operate with controlled substances
• Incorrect use of container types, particularly single-use containers in HFC imports
• Misuse of laboratory or essential-use exemptions

These errors are critical because the system does not allow correction at the customs stage; once a shipment is blocked, the outcome is typically rejection or forced return.

Compliance and Audit Impact – High Enforcement Sensitivity

This Communiqué operates under a high enforcement sensitivity model where compliance is assessed both at the point of import and through post-clearance review mechanisms.

Customs authorities verify:

• The existence and validity of required certificates
• Alignment between declared and actual goods
• Consistency between documentation and regulatory category

Post-clearance audits may re-evaluate transactions, particularly where there is suspicion of misuse of exemptions or incorrect classification.

In such cases, companies may face not only administrative penalties but also restrictions on future import activities, making early compliance planning essential.

Where disputes arise, structured resolution becomes critical through dispute and settlement advisory.

Strategic Actions – What Must Be Done Before Shipment

From a professional customs advisory perspective, compliance under this regulation must be structured entirely before shipment.

Companies should:

• Conduct detailed classification and regulatory category analysis
• Verify whether the substance falls under prohibition, quota, or conditional import
• Confirm container type compliance for HFC-related imports
• Secure all required approvals before export clearance
• Align commercial documents with regulatory requirements

Most importantly, companies must integrate quota management and calendar-based planning into their procurement strategies, particularly for HFC imports.

Professional Assessment – This Is a System-Controlled Import Model

From a senior customs consultancy standpoint, Communiqué 2026/6 represents a shift from document-based compliance to system-controlled import authorization.

The determining factors are no longer limited to documentation but include:

• Regulatory category accuracy
• System registration (TPS / FARAVET)
• Quota availability
• Purpose-based eligibility

In this environment, errors are not procedural—they are structural, and once they occur, they cannot be corrected operationally.

Companies that fail to integrate compliance into their supply chain planning will face repeated disruptions, while those that adopt a structured approach will maintain predictable operations.

Conclusion – Environmental Controls Define Import Feasibility

Communiqué 2026/6 establishes a regulatory model where environmental controls directly determine whether imports are possible, not merely how they are processed.

This transforms environmentally controlled chemical imports into high-risk, planning-driven operations where success depends entirely on correct classification, timely authorization, and disciplined execution before shipment.
