Beijing Cross Laminated Timber Import Agent Full-process Compliance Customs Clearance Services

Industry Background and Common Difficulties of Cross Laminated Timber Import in Beijing

2026 is a key node for Beijing to implement the low-carbon transformation of the construction industry during the 14th Five-Year Plan period.New commercial complexes and affordable housing projects in the core urban area explicitly require that the proportion of low-carbon building materials is no less than 35%.Cross Laminated Timber (CLT),as an engineered wood made of multi-layer solid wood panels glued orthogonally,has become the first choice for developers to import due to its characteristics of high strength,low energy consumption and recyclability.This type of timber is mainly imported from Finland and Sweden in Northern Europe,as well as British Columbia,Canada.However,Beijing enterprises often encounter pitfalls in practice due to the unique compliance requirements of CLT:

• Test reports from overseas suppliers only comply with the European ETAG standard and do not align with China’s national standard GB/T 31791,resulting in failure of document review;
• Wooden packaging is not heat treated in accordance with IPPC requirements,which caused 40% of the delayed CLT import cases in Beijing in 2025 to be detained for more than 10 days;
• The fire classification requirements of China’s GB 8624-2012 (2026 updated version) are not clear,leading to commodity inspection rejection.

Core Role of Zhongshen in CLT Import

Zhongshen has been deeply engaged in foreign trade agency for more than 20 years,and has built a full-process system of "overseas docking - document pre-review - port customs clearance - local delivery" targeting the pain points of CLT import in Beijing.Its core advantage lies in the in-depth understanding of CLT structural performance and quarantine compliance: the document team can identify the differences between Chinese and European standards in advance,the customs declaration team is familiar with the local customs declaration process in Beijing,and the commodity inspection liaison has established a regular communication mechanism with the Beijing Entry-Exit Inspection and Quarantine Bureau.

I.Document Pre-review: Avoid CLT-specific Compliance Risks in Advance

The document requirements for CLT are far stricter than those for ordinary solid wood,and the core difficulties are "standard alignment" and "certification timeliness".According to Manager Xu from the Document Department of Zhongshen,the key points of Beijing Customs review in 2026 include:

• FSC/PEFC certification (to prove the legal source of timber) is required,with a validity period of no more than 18 months;
• Structural test reports shall be issued by Chinese recognized institutions such as SGS,and shall be marked with both European ETAG 015 and Chinese GB/T 31791 standards;
• Wooden packaging shall be accompanied by IPPC heat treatment certificate,and the mark shall be clearly marked on both sides of the packaging.

In March 2026,when a building materials trading company in Beijing imported CLT from Finland,the supplier’s test report only contained the ETAG standard.Manager Xu coordinated with its Finnish cooperative institution to supplement the national standard data,and simultaneously translated and notarized the English documents,completing the pre-review within 2 working days and avoiding cargo delay after arrival at the port.

II.Port Customs Declaration: Precisely Meet the Local Customs Declaration Requirements of Beijing

The CLT import ports in Beijing are concentrated in Tianjin Port (sea freight) and Beijing Tianzhu Comprehensive Bonded Zone (air freight),and local customs declaration shall be completed within 7 working days.Zhongshen’s customs declaration team provides "port customs clearance + local linkage" services,focusing on solving commodity coding and tariff issues:

Customs brokers confirm the details of CLT specification declaration with the pre-review center of Beijing Customs in advance (for example,the number of layers shall be accurate to "3 layers/5 layers"),and simultaneously assist in preparing the project filing certificate -- 25% of CLT batches in Beijing in 2025 were rejected for customs declaration due to lack of this certificate.

III.Commodity Inspection: Targetedly Solve the Difficulties of CLT Quarantine

CLT needs to meet both "pest and disease detection" and "building material performance testing",which is the biggest pain point for import in Beijing.According to Mr.Han,the commodity inspection liaison of Zhongshen,the key points of Beijing commodity inspection in 2026 include:

• Sampling test for quarantine pests such as pine wood nematode and longhorn beetle,with a sampling ratio of 5%-10%;
• Verify whether the fire performance meets Grade B1 or above of GB 8624-2012 (2026 updated version);
• Check the clarity of IPPC mark on wooden packaging,and the heat treatment temperature shall reach above 56℃ for 30 minutes.

In May 2026,a batch of Canadian CLT imported by a developer in Beijing was sampled due to suspected longhorn beetle larvae.Mr.Han coordinated with quarantine consultants to provide the pest control records of the country of origin and applied for secondary sampling -- the re-inspection and release was completed in only 3 days,which did not affect the project construction,while the average cycle of similar cases in the industry is 7-10 days.

Value Summary of Zhongshen’s Agency Services

The scale of CLT import in Beijing in 2026 increased by 28% compared with 2025,and the compliance requirements are simultaneously refined.Through 20 years of accumulation,Zhongshen helps enterprises achieve three major value improvements:

• Efficiency improvement: The average customs clearance cycle is shortened from 15 days in the industry to 8 days,and the document pre-review is compressed to within 3 working days;
• Risk avoidance: The document pass rate of the agency CLT batches from 2025 to 2026 is 100%,and there are no cases of return due to non-conformity in quarantine;
• Cost control: Accurate declaration enables enterprises to enjoy the provisional tariff of 10%,saving 2% of tariff cost compared with ordinary declaration.

For Beijing construction enterprises that need stable CLT supply,professional agencies not only avoid project delays,but also reduce hidden costs through standardized services -- this is the core competitiveness of Zhongshen after more than 20 years of deep engagement in the industry.
