What We Do

A specialized marketplace for agricultural trade with China.

Zelenberg is a specialized B2B marketplace where buyers explore manufacturers, select agricultural products and equipment, submit Direct or Open RFQs, and receive quotation responses through the platform.

When needed, buyers can also use the optional services Zelenberg has made available to assist with specific stages of their purchase in China.

Why We Built It

Buying agricultural inputs and equipment from China requires more than product listings.

  1. Specialized products need a specialized marketplace

    Agricultural inputs and equipment involve technical specifications, applications and commercial details. Zelenberg was built to organize these products around the specific categories and information agricultural buyers need.

  2. Buyers need a clearer way to request quotations

    A structured RFQ allows buyers to communicate their product, quantity, packaging, destination and commercial requirements clearly, helping them receive more relevant responses.

  3. Manufacturers also need clear requirements

    Complete and structured RFQs help manufacturers understand what the buyer needs, respond more efficiently and focus on serious business opportunities.

  4. Some purchases need local assistance

    When an order moves forward, buyers may need local coordination or assistance with specific stages of their purchase in China. Zelenberg makes optional services available when that assistance is needed.

We built Zelenberg to make agricultural trade more focused, more organized and easier for both buyers and manufacturers to move forward.

Zelenberg is a marketplace that stays useful after the RFQ.

Zelenberg brings specialized product listings, structured RFQs and optional services together in one marketplace. Buyers choose the products and manufacturers themselves. When a purchase moves forward and assistance is needed in China, they can request the appropriate Zelenberg service for that particular stage.

Factories visited by our team

Every manufacturer listed on Zelenberg has been visited by our team on a recorded date. Each listing includes information and photographs collected during the visit, giving buyers additional context when reviewing the manufacturer and its products.

Services for specific stages of a purchase

Buyers can select individual services whenever needed—from an additional Factory Visit or Sampling & Delivery to a Production Report, Laboratory Testing, Pre-Shipment Report or Container Loading Report.

A clear record in one place

RFQs, quotation responses, service requests, invoices and reports remain organized in the buyer’s account, making it easier to follow each request and access the relevant information as the purchase progresses.

What We Cover

Six Connected Categories. Built Around Your Business.

Find the products, packaging and equipment to expand your range and build your brand. Our curated marketplace connects you directly with manufacturers in China for OEM, ODM and other sourcing needs—with services to support your order.

Agrochemicals

Explore crop-protection products, technical ingredients and custom formulation options for OEM and ODM orders under your brand.

Why These Six

Different products. The same agricultural business.

They serve connected purchasing needs

Agricultural businesses that buy fertilizers and crop-protection products may also need packaging, production equipment, agricultural machinery or greenhouse systems. Bringing these product areas together reflects how these businesses actually operate.

China has strong manufacturing capabilities

China has an established manufacturing base across all six product areas, with specialized factories producing a broad range of products, equipment and customized solutions.

The details matter

Formulation, concentration, materials, dimensions, capacity, compatibility and packaging can all influence a purchasing decision. A focused marketplace can organize and present these details more effectively.

Built on practical experience

Zelenberg’s product areas, categories and optional services reflect years of practical experience working with agricultural products, manufacturers in China and international buyers.

How It Works

How Zelenberg works: from product discovery to the service you need.

Exploring products, submitting RFQs and receiving quotation responses are free. Buyers control each step, while RFQ routing and offer organization are handled automatically by the Zelenberg platform.

  1. FREE — MARKETPLACE & RFQ · STAGES 1–3

    Explore products

    Review agricultural inputs and equipment from manufacturers listed on Zelenberg. Select a specific product or define a broader purchasing requirement.

  2. Submit an RFQ

    Submit a Direct RFQ from a selected product listing, or use an Open RFQ when you want to receive offers for a broader requirement.

  3. Receive quotation responses

    Manufacturers have up to 24 hours to respond. A Direct RFQ returns the selected manufacturer’s response. For an Open RFQ, the platform automatically routes the request to relevant listed manufacturers and presents three to five best-matched offers in one consolidated comparison.

  4. OPTIONAL SERVICES · STAGES 4–8

    Choose the service you need

    Select a service for a specific stage of your purchase involving a manufacturer listed on Zelenberg.

  5. Submit your service request

    Provide the factory, product, preferred date and any specific instructions or requirements related to the service.

  6. Confirm the scope and invoice

    Zelenberg coordinates the request with the factory and confirms the scope, timing and applicable costs. The invoice is issued before the service begins.

  7. The service is carried out

    After payment, a Zelenberg team member completes the agreed service on the confirmed date and records the requested information.

  8. Receive the result

    The report and any available photographs, videos, tracking details or laboratory documents are uploaded to your dashboard and delivered through your selected communication channels.

Our work takes place in China. Import clearance, duties, product registration and delivery inside your country stay with you or your customs broker.

AgroAgent

AgroAgent: one order, one coordination plan.

AgroAgent is for buyers who want Zelenberg to coordinate the agreed stages of an active order in China. Before work begins, we review the order and provide a defined scope, timeline and known costs.

Once the scope is confirmed and the invoice is paid, our team coordinates the included stages—from contract and payment follow-up to OEM packaging, production schedules, sampling, laboratory testing, shipment arrangements, loading and final documents.

The buyer continues to make the product, manufacturer and commercial decisions. Zelenberg does not receive commissions from manufacturers.

Start with a product—or submit your requirement.

Choose a product listed on Zelenberg and submit a Direct RFQ to its manufacturer. If you have not selected a specific product or manufacturer, submit an Open RFQ and describe what you need.

The platform automatically routes your request to relevant listed manufacturers and presents three to five best-matched quotation responses in one consolidated comparison.

Both RFQ options are free. If your purchase moves forward and you need assistance with a specific stage in China, Zelenberg’s optional services remain available.
