Why 2026 Is Now the Only Deadline That Matters for Turkey REACH (KKDIK) Compliance

The recent regulatory update to Turkey’s KKDIK regulation (often referred to as Turkey REACH) will fundamentally change how companies should approach compliance.

For several years, companies understood KKDIK as a phased regulatory process, similar to EU REACH, with staggered deadlines extending to 2028 and 2030. This would allow many organizations to take a gradual approach to registration, often relying on Lead Registrants and industry timelines.

But the authorities have now introduced individual interim registration requirements and a hard compliance deadline of September 30, 2026, which means that companies can no longer rely on phased timelines alone.

The focus has shifted from long-term planning to immediate action. This guide explains what has changed, what it means in practice, and what companies should do now to maintain access to the Turkish market.

What Is KKDIK?

KKDIK (Registration, Evaluation, Authorization and Restriction of Chemicals) is Turkey’s main chemical regulation, closely aligned with the EU REACH framework. It came into force on December 23, 2017.

It applies to:

• Substances manufactured in Turkey;
• Substances imported into Turkey; and
• Substances in mixtures and certain articles.

Companies manufacturing or importing substances above 1 ton per year are required to register those substances with the Ministry of Environment, Urbanization and Climate Change.

Non-Turkish companies can appoint a Turkey-based Only Representative (OR) to fulfill these obligations.

What Has Changed?

The recent update introduced a major shift in how compliance timelines are structured and enforced.

A Single Critical Deadline

All substances must now have either:

• A full registration; or
• An interim (provisional) registration

by September 30, 2026.

Companies that fail to meet this deadline will not be permitted to place those substances on the Turkish market.

Companies that have already obtained full registration numbers do not need to carry out interim registrations for the same substance.

Pre-Registration Is No Longer Sufficient

Previously, pre-registration allowed companies to:

• Remain active in the market; and
• Defer full registration

Under the updated framework:

• Pre-registration numbers will no longer be valid for market access.
• Only registration (full or interim) will be recognized.

This removes a key safety net that many companies have relied on.

Reduced Dependence on Lead Registrants

Previously, many companies planned to:

• Wait for a Lead Registrant; and
• Follow joint submission timelines.

The new rules mean that companies must ensure their own compliance by the 2026 deadline, regardless of whether a Lead Registrant has completed their submission.

Interim Registration Is Now a Strategic Tool

The introduction of interim registration is one of the most significant changes under the updated framework.

It allows companies to:

• Submit incomplete dossiers;
• Justify missing data; and
• Obtain an interim registration number to maintain market access.

However, interim registration is not just a fallback option – it is now a strategic compliance pathway.

In practice, companies may need to prioritize individual interim registration where:

• A Lead Registrant has not completed registration.
• A Letter of Access (LoA) is not yet available.
• No Lead Registrant has been identified.
• Companies choose not to participate in a joint submission.

This creates a shift away from reliance on industry timelines toward independent decision-making.

Market Access Is Now Binary

After September 30, 2026:

• Substances with a valid registration number → can remain on the market
• Substances without one → cannot be legally supplied

This creates a clear regulatory threshold with direct commercial consequences.

What This Means for Companies

These changes significantly alter the compliance landscape, and the timeline has effectively been compressed.

While phased deadlines (2028 and 2030) still exist, they are no longer the key decision point for market access. 2026 is now the operational deadline that determines whether a company can continue doing business in Turkey. As a result, companies must move from passive planning to active decision-making.

How Companies Should Choose Their Registration Path

Given the compressed timeline, companies must now actively decide how they will achieve compliance before September 30, 2026.

In practice, this will largely depend on the Lead Registrant's progress and data availability.

The appropriate approach will depend on the status of the substance:

• Where a Lead Registrant has shared LoA terms – Companies can proceed with joint submission and full registration, or consider individual interim registration if timelines or costs are uncertain.
• Where a Lead Registrant exists but LoA terms are not yet available – Companies can wait for confirmation in the short term, but should be prepared to move to individual interim registration if progress is delayed.
• Where no Lead Registrant exists – Individual interim registration might be the most practical route to ensure compliance.

Compliance must Happen Earlier

Companies can no longer delay action based on:

• Tonnage band deadlines; and/or
• Lead Registrant timelines.

Preparation must begin now to ensure that at least interim registration is in place. Risk exposure has increased, and failure to act could result in:

• Loss of market access;
• Supply chain disruption; and
• Commercial impact.

What Companies Should Do Now

The changes to KKDIK require a more proactive and structured approach to compliance.

Companies should:

• Review their substance portfolio and confirm regulatory status;
• Assess Lead Registrant progress and LoA availability;
• Identify data gaps and prepare documentation; and
• Determine whether interim registration is required.

For many companies, the key step is not just preparing data, but deciding when to act independently rather than waiting for a joint submission to progress.

Conclusion

The latest KKDIK updates mark a turning point in Turkey’s chemical regulatory framework. The introduction of a firm 2026 deadline and the shift toward individual registration responsibilities mean that companies must act sooner than previously expected.

Organizations that take early action will be better positioned to:

• Maintain market access;
• Manage compliance costs; and
• Reduce regulatory risk.

Those who delay might face significant operational and commercial challenges. If you’d like to discuss how these changes may affect your products or supply chain, feel free to get in touch.
