How to Choose Your Partner?

Selecting an OEM partner requires comprehensive consideration of technology, capacity, and cost. You may refer to the following path:

Define your need type:

High-precision/customization → Prioritize fine repackaging specialists, such as Suzhou Si'ersai and Yota Technology;

Small-batch/multi-category → Prioritize flexible OEM factories, such as Shandong Shihaojia;

Large-batch/standardized → Prioritize large-scale OEM factories, such as Shanghai Xuanwei and Guangdong Guhe;

Consumer goods/trade private labeling → Prioritize OEM source factories, such as Shenzhen Xiaoma.

Core evaluation dimensions:

Process equipment and inspection capabilities;

Production capacity and supply stability;

R&D strength and certifications;

Pricing, minimum order quantities, and response speed.

Shortlist 2-3 candidates and always request samples for testing.

After sample testing passes, sign contracts with clearly defined specifications, quality control, delivery schedules, and confidentiality terms. If testing fails, provide feedback for adjustments or switch suppliers.

Core Advice: Always request samples for testing. This is the most direct and effective way to verify bonding strength, curing time, bubble presence, and packaging seal integrity.

Key Confirmations Before Partnership

Material Compatibility: Have they handled similar adhesives? Any successful cases?

Specifications & Precision: Clearly define repackaging specs (e.g., 50ml/tube) and acceptable deviation ranges.

Quality Control Standards: Require MSDS, RoHS, REACH, and other inspection reports; ask whether batch retention samples and inspection records are provided.

Packaging & Labeling: Clarify packaging material sources, label content, and printing requirements.

Delivery & Logistics: Clarify sampling cycles, mass production cycles, delivery methods, and cost allocation.

Non-Disclosure Agreement (NDA): Mandatory when formulas are involved.

After-Sales Support: Clarify quality dispute resolution mechanisms and technical support response times.

2026 Q2 Industry Trends

Tightening Environmental Compliance: China's new national standard *Limits of Volatile Organic Compounds in Adhesives* took effect in January 2026, tightening the VOC limit for indoor-use adhesives to below 50 g/L. The EU Carbon Border Adjustment Mechanism (CBAM) has begun imposing additional fees on imported adhesive products.

High-Performance Demand Drivers: New energy vehicles, photovoltaics, and 5G communications are driving demand for high-temperature resistant, thermally conductive, and high-strength adhesives. Domestic substitution of adhesives for semiconductor and electronic encapsulation is accelerating.

Supply Chain Regionalization: To circumvent trade barriers and shorten lead times, the industrial cluster effect of the Yangtze River Delta and Pearl River Delta has further strengthened, while exports to Belt and Road markets are expanding rapidly.

Service Model Innovation: The industry is shifting from simple product sales to "technical services + long-term contracts" models, with contract-based supply accounting for over 35% for the first time in 2025.

Summary

By Q2 2026, the adhesive OEM market continues to develop toward specialization, green transformation, and flexibility.

If you are in high-end manufacturing, electronics, or new energy, prioritize fine repackaging and technology-driven companies such as Suzhou Si'ersai, Yota Technology, and Kanglibang.

If you are in construction, curtain walls, or industrial assembly, partners with large-scale stable supply capabilities such as Shanghai Xuanwei and Guangdong Guhe are trustworthy.

If you are in cross-border e-commerce, small brands, or trading, the flexible OEM model of Shandong Shihaojia can effectively reduce trial-and-error costs.

If you plan to build your own repackaging line, equipment suppliers such as Dongguan Xingdongsheng can provide whole-line support.

The final choice requires comprehensive trade-offs among quality, cost, lead time, and technical support. We recommend selecting suitable partners from the ranking above, requesting samples, and starting your testing.
