September 2026 | Ho Chi Minh City & Surrounding Provinces, Vietnam
After concluding our participation at VietnamPlas 2026, the Shandong Changxing team remained in Vietnam to visit customer factories across the country. These post-show visits transformed exhibition contacts into substantive business relationships. From witnessing our exported MEG cargo being unloaded at a customer factory to confirming a DOTP purchase, this article documents real buyer stories from the Vietnamese market.
This article is intended for chemical buyers, procurement managers, and industry observers interested in the practical realities of B2B chemical trade between China and Vietnam. It provides firsthand accounts of factory conditions, product performance feedback, and the value of in-person relationship building.
Visit Highlights
- MEG delivery witnessed: Observed our exported MEG cargo being unloaded at a Vietnamese customer factory.
- DOTP purchase confirmed: A PVC granules company had already purchased DOTP.
- Factory tours completed: Visited multiple PVC granules factories to understand production processes and quality requirements.
- Long-term relationships: Met with a Chinese entrepreneur who has operated a factory in Vietnam for over 10 years.

MEG Delivery at Customer Factory
Our first visit took us to a Vietnamese customer who had purchased MEG (Monoethylene Glycol) from Shandong Changxing. We arrived at the factory while our exported MEG cargo was being unloaded. That moment provided tangible confirmation of ongoing trade and let our team observe the customer's receiving process firsthand.
The customer uses MEG for antifreeze blending and chemical synthesis. During the visit, we discussed their current inventory levels, upcoming order schedules, and packaging preferences for future shipments. The face-to-face interaction strengthened the working relationship and provided valuable feedback on our logistics performance.
DOTP Purchase at PVC Granules Company
The second visit was to a PVC granules manufacturing company that had already purchased DOTP from Shandong Changxing. This was not a prospective lead. The company was a confirmed buyer, and our DOTP was already running in its production line.
The company produces PVC granules for various applications and had been evaluating DOTP as a phthalate-free alternative. Their feedback on our DOTP was positive: gelation behavior met expectations, compatibility with their PVC resin was good, and the cost-performance ratio compared favorably with alternatives they had tested. They expressed interest in placing larger orders once their current inventory is utilized.
Chinese Entrepreneur's Factory in Vietnam
One of the most interesting visits was to a factory owned by a Chinese entrepreneur who has been operating in Vietnam for more than 10 years. His facility produces PVC products for the local Vietnamese market and has established a stable customer base over the past decade.
The factory owner discussed his current MEG requirements for antifreeze production and expressed interest in establishing a direct supply relationship with Shandong Changxing. He emphasized the importance of consistent quality, reliable delivery schedules, and competitive pricing for long-term cooperation. His experience navigating the Vietnamese market over 10 years provided valuable insights for our regional strategy.
Local PVC Granules Factory Tours
Additional visits included tours of local Vietnamese PVC granules factories. One factory had previously received samples from Shandong Changxing and was currently conducting internal testing. Our team observed their production lines, discussed their quality control procedures, and provided technical guidance on DOTP loading levels for their specific PVC formulations.
These factory tours provided direct insight into the operational realities of Vietnamese PVC processors: equipment capabilities, raw material handling procedures, quality benchmarks, and the practical challenges of sourcing reliable chemical inputs. This ground-level understanding is essential for tailoring our product specifications and service offerings to the Vietnamese market.
Products Discussed During Visits
Two product lines were the primary focus of the customer visits. The table below summarizes each product and its relevance to the Vietnamese market.
| Product | CAS No. | Core Specification | Key Applications |
|---|---|---|---|
| MEG (Monoethylene Glycol) | 107-21-1 | Purity 99.5%+ | Antifreeze, PET resin, chemical synthesis |
| DOTP | 6422-86-2 | Cost-effective general-purpose grade | PVC flooring, films, profiles, granules |
Why In-Person Visits Matter
Direct Process Understanding
Seeing a customer's production line reveals equipment capabilities, bottlenecks, and quality control procedures that cannot be conveyed in emails or video calls.
Relationship Building
Face-to-face interaction builds trust and demonstrates commitment. Customers are more likely to share honest feedback and discuss long-term plans in person.
Immediate Problem Solving
Technical questions about product application, storage, or handling can be addressed on the spot, reducing delays and miscommunication.
Market Intelligence
Visiting multiple customers in one region reveals broader market trends, competitive dynamics, and emerging opportunities.
Next Steps for the Vietnam Market
Based on the feedback gathered during these visits, Shandong Changxing will take the following actions to strengthen our presence in the Vietnamese market:
- Expand MEG supply: Increase MEG shipment frequency to meet growing antifreeze and chemical synthesis demand.
- Scale DOTP orders: Work with the PVC granules company to transition from trial quantities to regular bulk orders.
- Provide technical support: Offer formulation guidance and loading recommendations for customers transitioning to phthalate-free plasticizers.
- Schedule regular visits: Establish a quarterly visit schedule to maintain relationships and stay informed about market developments.

Frequently Asked Questions
Which customers did Shandong Changxing visit after VietnamPlas 2026?
We visited four customer sites: a MEG customer factory where our exported cargo was being unloaded, a PVC granules company that had purchased DOTP, a factory owned by a Chinese entrepreneur with 10+ years in Vietnam discussing MEG supply, and a local PVC granules factory that had received samples for testing.
What products were discussed during the customer visits?
The main products discussed were MEG (Monoethylene Glycol, CAS 107-21-1) for antifreeze and chemical synthesis, and DOTP (CAS 6422-86-2) for PVC compounding. Both products are manufactured by Shandong Changxing with full ISO and REACH compliance.
Did any transactions occur during the visits?
Yes. One PVC granules company had already purchased DOTP from us. At another customer site, we witnessed our exported MEG cargo being unloaded at the factory. These visits confirmed real demand and ongoing business relationships.
What is the advantage of visiting customers in person?
In-person visits allow us to understand the customer's production process, quality requirements, and logistics needs directly. This helps us tailor our product specifications, packaging, and delivery schedules to match actual factory operations.
