Understand general product applications
Check available models and capacities
Submit a machinery requirement
Request technical specifications
Ask for customization
Request pricing or a quotation
Contact our team for a technical discussion

Unless a specific online purchasing facility is introduced and expressly identified, displaying a machine on this website does not constitute an automatic offer to sell, and submitting an enquiry does not create a confirmed order.

3. Acceptance of These Terms

By continuing to use this website, you confirm that:

You have read and understood these Terms and Conditions.
You are legally capable of entering into a business transaction.
Where you act for a company, factory, firm, partnership, or other organization, you are authorized to communicate and submit requirements on its behalf.
The information you provide is accurate and not misleading.
You will use the website only for lawful business and informational purposes.

Where you do not agree with these Terms and Conditions, you should discontinue using the website and avoid submitting business or technical information through it.

4. Product Information on the Website

We make reasonable efforts to present useful and accurate machinery information. However, website content is provided for general product understanding and preliminary evaluation.

Product photographs, illustrations, videos, specifications, capacities, dimensions, components, features, layouts, and descriptions may vary from the machine ultimately supplied because of:

Model selection
Production capacity
Pipe or material requirements
Customer-requested customization
Component availability
Design improvements
Safety or engineering modifications
Power and site requirements
Manufacturing updates

The final scope of supply will be based only on the specifications confirmed in the accepted quotation, technical document, invoice, or written order agreement.

A product image may contain optional equipment, accessories, safety arrangements, or visual elements that are not included in the standard quoted price.

5. Product Performance and Production Capacity

Production capacities shown on the website or discussed during an enquiry are indicative unless expressly committed in an accepted technical document.

Actual machine performance may depend on factors such as:

Raw material type and quality
Moisture, contamination, and material condition
Input particle or pipe size
Blade, disc, screen, heater, or tooling configuration
Electrical voltage and power stability
Water or compressed-air availability
Operator knowledge and working method
Maintenance condition
Ambient factory conditions
Feeding consistency
Upstream and downstream equipment
Customer-provided process parameters

The buyer is responsible for providing accurate production details before finalizing the machine. Dass Engineering Private Limited cannot be held responsible for reduced output caused by unsuitable raw material, incorrect operation, inadequate utilities, unauthorized modifications, or conditions outside the agreed machine specifications.

6. Product Enquiries

You may submit an enquiry through:

Website forms
WhatsApp
Telephone
Email
An in-person meeting
An authorized business representative

An enquiry is only a request for information. It does not reserve machinery, confirm availability, fix a price, or create a binding purchase contract.

To help us recommend a suitable machine, we may request details such as:

Material to be processed
Pipe size or product application
Required production capacity
Input size and condition
Preferred automation level
Electrical power availability
Factory location
Available installation space
Delivery destination
Expected purchase timeline
Customization requirements

The quality of our recommendation depends on the accuracy and completeness of the information supplied by the customer.

7. Quotations and Commercial Proposals

A quotation issued by Dass Engineering Private Limited may contain:

Product name and model
Technical specifications
Production capacity
Scope of supply
Included components
Optional accessories
Price
Applicable taxes
Payment schedule
Estimated manufacturing period
Freight or delivery terms
Installation or commissioning conditions
Warranty coverage
Exclusions
Validity period

A quotation is valid only until the date stated in it. After expiry, the price or delivery period may be revised due to changes in raw-material costs, component prices, taxes, freight charges, currency rates, labour costs, or production availability.

Prices discussed over the telephone or through informal messaging are not final unless confirmed in an official written quotation or invoice.

8. Order Confirmation

An order is considered accepted only when:

The technical and commercial specifications have been agreed upon;
Dass Engineering Private Limited has issued or accepted a written order confirmation, quotation, invoice, or equivalent commercial document; and
The required advance payment or other agreed consideration has been received.

A customer purchase order is not automatically binding on Dass Engineering Private Limited if it contains terms that conflict with our quotation. Any conflicting or additional terms must be expressly accepted by an authorized representative in writing.

Informal conversations, preliminary estimates, marketing materials, social media posts, and website content do not override the final accepted order documents.

9. Electronic and WhatsApp Communication

Customers may communicate with us through email, WhatsApp, website forms, and other electronic channels. Electronic proposals, acceptances, and records can have legal recognition under India’s Information Technology Act, including Section 10A concerning contracts formed through electronic means.

However, casual discussions, unanswered messages, automated confirmations, or preliminary exchanges should not be treated as final order acceptance unless the communication clearly confirms the relevant technical and commercial terms.

Customers should preserve copies of quotations, approvals, payment records, and order confirmations.

10. Customized Machinery

Many industrial machines are manufactured or configured according to customer-specific requirements.

Before manufacturing begins, the customer must carefully review and confirm:

Machine model
Material application
Capacity requirement
Input and output conditions
Electrical specifications
Dimensions
Tooling
Automation level
Accessories
Scope of supply
Factory conditions
Delivery requirements

Once approved, changes may not always be technically or commercially possible.

Where a customer requests changes after design, component procurement, fabrication, assembly, or testing has begun, Dass Engineering Private Limited may:

Revise the price
Extend the production timeline
Charge for additional material or labour
Reject changes that affect safety or performance
Require written approval before proceeding

Dass Engineering Private Limited is not responsible for issues resulting from incomplete, inaccurate, or subsequently altered customer requirements.

11. Customer-Supplied Drawings, Samples and Information

Where the customer provides drawings, dimensions, samples, photographs, technical files, or process information, the customer confirms that:

The information is accurate.
It has the authority to share the material.
Our use of the material for the order will not violate third-party rights.
Relevant dimensions and tolerances have been verified.
Any unusual application or safety requirement has been disclosed.

We may rely on customer-approved information while designing or manufacturing the machine. Additional costs arising from incorrect information or revised samples may be charged to the customer.

12. Pricing and Taxes

Unless expressly stated otherwise in the quotation:

Prices are quoted in Indian rupees.
GST and other applicable taxes are charged separately.
Freight and transit insurance are excluded.
Unloading and internal factory movement are excluded.
Foundation, civil, plumbing, electrical, water, and compressed-air work are excluded.
Installation, travel, accommodation, and technician expenses are excluded unless specifically included.
Consumables and production raw materials are excluded.
Export duties, destination taxes, customs charges, and local regulatory fees are borne by the international buyer.
Bank, payment gateway, and currency-conversion charges are borne by the customer.

The accepted quotation or invoice will determine the final price and inclusions for each order.

13. Payment Terms

Customers must make payment according to the schedule mentioned in the accepted quotation, invoice, or order confirmation.

The payment structure may include:

Advance payment
Stage payment during manufacturing
Balance before dispatch
Another schedule accepted in writing

Manufacturing, procurement, testing, dispatch, installation, or technical services may be paused where a payment becomes overdue.

Any resulting delay will not be counted as a delay attributable to Dass Engineering Private Limited.

Ownership of the machine may remain with Dass Engineering Private Limited until full payment and all agreed charges have been received, subject to the applicable written order terms and law.

14. Manufacturing and Completion Period

Manufacturing timelines are estimated from the date on which all required conditions have been completed, including:

Receipt of advance payment
Approval of specifications

Where the customer does not attend after reasonable notice, we may conduct internal testing and proceed according to the accepted order terms.

Special testing material, tooling, or process conditions required exclusively for the customer may need to be provided or paid for by the customer.

16. Delivery and Transportation

Delivery terms will be specified in the quotation or order confirmation.

Depending on the agreement:

The customer may arrange transportation.
Dass Engineering Private Limited may coordinate transportation through an independent logistics provider.
Freight may be charged separately.
Transit insurance may be arranged by the customer or included only when expressly mentioned.

Transporters and logistics providers operate independently. Their delays, route changes, handling practices, or service failures may be outside our direct control.

The customer must ensure that the delivery address, contact details, road access, entry permissions, and unloading arrangements are correct and available before dispatch.

17. Transit Damage and Delivery Inspection

The customer should inspect the packaging and machinery immediately upon delivery.

Visible damage, shortage, or mishandling should be:

Recorded on the transporter’s delivery receipt;
Photographed or filmed before unloading where possible; and
Reported promptly to Dass Engineering Private Limited and the transporter.

Claims relating to transit damage may require the original delivery receipt, photographs, videos, transporter acknowledgement, invoice, and packing details.

Damage caused during unloading, internal shifting, crane handling, forklift operation, or storage at the customer’s premises is the customer’s responsibility unless those activities were expressly included in our scope.

18. Site Readiness and Installation

Where installation or commissioning support is included or separately arranged, the customer must prepare the factory before the technician or machine arrives.

Site readiness may include:

The applicable written warranty terms will prevail over general promotional content.

21. After-Sales and Technical Support

Dass Engineering Private Limited may provide technical assistance through:

Telephone
WhatsApp
Video call
Email
Technical documents
Site visits where agreed

Remote support may require the customer to provide clear photographs, videos, machine settings, electrical readings, and a description of the problem.

Site visits outside the agreed warranty or support scope may involve travel, accommodation, labour, and service charges.

22. Cancellation by the Customer

Machinery may be designed, procured, or manufactured specifically for a customer. Therefore, an order cannot be cancelled automatically after acceptance.

A cancellation request must be submitted in writing and is subject to approval by Dass Engineering Private Limited.

Where cancellation is accepted, we may deduct or recover costs already incurred, including:

Engineering and design work
Raw materials
Purchased components
Fabrication
Machining
Labour
Administration

Banking charges
Storage
Other order-specific expenses

Advance payments may become non-refundable once design, procurement, or manufacturing has begun, subject to the applicable order documents and mandatory legal rights.

23. Returns and Refunds

Industrial machinery manufactured or configured for a particular requirement is not ordinarily eligible for return because of a change of preference, incorrect customer selection, lack of site readiness, or revised production plans.

A return, refund, repair, or replacement may be considered where:

The supplied machine materially differs from the accepted specification;
A confirmed manufacturing defect is identified; or
The applicable written warranty provides a remedy.

The appropriate remedy will depend on technical inspection, the nature of the issue, the written order terms, and applicable law.

Nothing in these Terms is intended to remove a legal right that cannot lawfully be excluded. Government consumer resources describe consumer protection principles including transparency and fair treatment, although the legal treatment of a particular purchase can depend on whether it qualifies as a consumer or commercial transaction.

24. Storage Charges and Delayed Dispatch

Where a machine is ready but dispatch is delayed because of customer instructions, overdue payment, unavailable transport, incomplete documentation, or an unprepared factory site, we may store the machine for a reasonable period.

Additional storage, handling, preservation, insurance, or re-testing charges may apply where the delay continues beyond the agreed or reasonable period.

The customer remains responsible for completing the outstanding requirements necessary for dispatch.
