OEM/ODM evaluation criteria for 2026
From a procurement standpoint, the key documentation items during evaluation are the same across most export markets. For European-bound shipments, CE marking under harmonized standards is a primary compliance filter. For North American projects, ASTM C920 and ASTM C1184 are commonly cited specifications for elastomeric joint sealants and structural sealants, respectively. Sourcing teams should verify that the factory’s certificates and batch testing records match the destination market requirements at the time of order.
Kastar’s published operating parameters illustrate the information now expected from an OEM/ODM partner. The company quotes a monthly production capacity of 30,000 tons, a lead time of 15–20 days, and a minimum order quantity of 100 buckets for OEM orders. Its products pass through 12 production and testing processes from production to delivery, with batch sample testing during every stage. The company states that it applies 100% testing and operates fully automated packaging equipment developed and produced in-house.
Market impact
The shift toward 100% silicone elastomeric systems is visible in the composition-type data reported by Mordor Intelligence for 2025, where this category held a 41.02% share. For OEM/ODM buyers, this supports the value of suppliers with documented silicone formulation experience, UV-resistance testing, and certification covering roof and exterior-wall applications. Kastar reports that its CE-compliant products have been adopted in construction projects in several regions, including the EU, North America and Southeast Asia, with stated application history covering roof waterproofing, exterior wall waterproofing, bathroom and balcony waterproofing, and basement and underground structure waterproofing. The growth projection published by Grand View Research — from roughly USD 8.77 billion in 2024 to USD 11.27 billion by 2033 — suggests that demand for export-oriented production capacity will continue through the current decade.
Outlook
As the 2026 procurement cycle continues, importers and contractors are expected to apply structured criteria: verified certification, audited manufacturing capacity, customization responsiveness, lead-time reliability and post-shipment support. The ten companies profiled above represent the main types of suppliers in China’s registered waterproofing supply chain, from listed industry benchmarks to specialized OEM/ODM bases such as Kastar. The CE certificate recorded for the Kastar 4000 system provides one documented reference point for buyers completing their 2026 shortlists.
