China Customs Opens TS EN ISO 898-1:2025 Make-up Channel for High-Tensile Bolts to Turkey

On April 29, 2026, China Customs General Administration announced the opening of a green-channel make-up procedure for TS EN ISO 898-1:2025 type approval certificates for high-tensile bolts exported to Turkey. This measure directly affects fastener manufacturers, export trading companies, and supply chain service providers engaged in mechanical component trade with Turkey — particularly those handling structural or automotive-grade bolt shipments.

Event Overview

On April 29, 2026, the General Administration of Customs of the People’s Republic of China issued an official notice confirming the launch of a make-up channel for TS EN ISO 898-1:2025 type approval certificates applicable to high-tensile bolts destined for Turkey. Under this arrangement, exporters facing certification delays may apply for temporary customs clearance using factory test reports and signed commitment letters. The temporary measure remains valid until September 30, 2026.

Which Subsectors Are Affected

Direct Export Trading Enterprises

These enterprises are impacted because Turkish import regulations require TS EN ISO 898-1:2025 compliance for high-tensile bolts — a requirement previously causing shipment holds and order delays. The new channel allows provisional release, reducing demurrage and contract penalty risks — but only for orders already in transit or pending clearance as of the policy’s effective date.

Manufacturing Enterprises (Fastener Producers)

Producers supplying high-tensile bolts to Turkish markets face immediate operational adjustments: they must now generate compliant factory test reports aligned with TS EN ISO 898-1:2025 (not earlier editions), and prepare legally binding commitment letters. Non-compliant internal testing protocols or outdated reporting templates could disqualify applications under the green channel.

Supply Chain & Logistics Service Providers

Freight forwarders and customs brokers handling Turkey-bound fastener consignments must verify whether documentation meets the specific evidentiary criteria (e.g., test report scope, signatory authority, language requirements) outlined in the Customs notice. Misclassification of bolt grade or tensile class may lead to rejection of temporary clearance requests.

What Relevant Enterprises or Practitioners Should Focus On and How to Respond

Monitor official implementation guidance from China Customs and Turkish authorities

The notice confirms the channel’s existence but does not publish detailed application forms, accepted test report formats, or verification timelines. Enterprises should track updates from both China Customs’ official website and Turkey’s TSE (Turkish Standards Institution) for alignment on interpretation — especially regarding acceptable deviations between factory reports and full third-party certification.

Verify product classification against TS EN ISO 898-1:2025 scope

TS EN ISO 898-1:2025 applies specifically to bolts, screws, and studs with specified mechanical properties. Not all fasteners qualify. Enterprises must confirm that their exported items fall within the standard’s defined property classes (e.g., 8.8, 10.9, 12.9) and thread dimensions — misalignment may render the green channel inapplicable regardless of documentation quality.

Distinguish between policy signal and operational readiness

Analysis shows this is primarily a transitional relief mechanism, not a permanent regulatory relaxation. Its September 30, 2026 expiry signals that full TS EN ISO 898-1:2025 certification remains mandatory beyond that date. Enterprises should treat the channel as a short-term bridge — not a substitute for initiating formal type approval processes with accredited Turkish or EU-notified bodies.

Prepare documentation proactively for pending and near-term shipments

Factory test reports must include minimum required parameters: tensile strength, yield strength, elongation, hardness, and proof load — all tested per EN ISO 898-1:2025 methods. Commitment letters must be signed by authorized company representatives and explicitly state willingness to submit full certification upon request. Pre-validating these documents with customs brokers ahead of filing avoids processing delays.

Editorial Perspective / Industry Observation

Observably, this move reflects a coordinated response to a recent bottleneck in Turkey’s market access requirements — one emerging after the 2025 revision of TS EN ISO 898-1 introduced stricter traceability and testing conditions. It is less a shift in long-term regulatory stance and more a pragmatic adjustment to prevent systemic disruption in a high-volume, low-margin segment. From an industry perspective, the channel serves as both a short-term operational reprieve and a clear signal that Turkish conformity assessment infrastructure is tightening — making early engagement with notified bodies increasingly strategic, not optional.

Current developments suggest this is a time-bound administrative accommodation, not a de facto lowering of standards. Its limited duration and conditional eligibility indicate that regulatory alignment — not procedural leniency — remains the underlying objective.

Conclusion

This initiative mitigates immediate delivery pressure for exporters of high-tensile bolts to Turkey but does not alter the fundamental requirement for TS EN ISO 898-1:2025 compliance. It is best understood as a targeted, temporary facilitation — not a policy reversal. Enterprises should use the window to resolve certification backlogs while treating full conformity as non-deferrable beyond September 2026.
