Key terms at a glance

Four things most customers want to know first

These four points drive the largest share of questions our engineering and sales teams answer. Each links straight to the clause it comes from.

Quotation validity
30 days
Prices hold for 30 days from issue and cover the full order quantity. Reduced quantities are re-quoted. Clause 02 →
What we build from
3D CAD is authoritative
Fabrication follows your 3D model. 2D PDFs are reference only — for tolerances, threads and finishes. Clause 04 →
Claim windows
7 days / 2 weeks
Shortages reported within 7 days of receipt. Rework or correction claims within 2 weeks of delivery. Clause 07 →
Expedite requests
Added cost, by you
Faster lead times are quoted on request. Extra labour and machine time are passed through at cost. Clause 06 →

01Scope & acceptance

These terms apply to every quotation we issue, every purchase order we accept, and every invoice we raise. Where a quotation, statement of work or signed agreement states something different, that document takes precedence over this page.

Who these terms are betweenCustomer of record
The entity placing the order. If you order on behalf of a company, you confirm you are authorised to bind it.
How acceptance happensOrder placement
Placing a purchase order against one of our quotations — or uploading production files after quoting — constitutes acceptance of these terms.
When there is a conflictOrder of precedence
  • A signed agreement or NDA, if one exists
  • The specific quotation or statement of work
  • These terms and conditions
Written in plain language We keep this page readable on purpose. The wording here is the operative wording — if you need it in a signed document for your file, ask us and we will issue one.

02Pricing & quotations

Basis of priceRFQ information
All prices are based on the information you provide during the RFQ process. Every price is all-inclusive: the quoted rate applies only when all units on the quote are ordered.
Validity30 days
Quotations are valid for 30 days from the date of issue unless the quotation states otherwise.
When we re-quoteChanges to scope
We reserve the right to re-quote where quantities are reduced, or where materials, colour, finishing or process change after quoting.
Taxes & dutiesEx-tax, FCA
Prices exclude sales tax, VAT, customs duty and any other government charge, which are payable by the customer where applicable. Unless the quotation says otherwise we sell FCA our facility (Incoterms 2020): the customer is the importer of record and is responsible for import clearance, duties and import taxes. We do not quote Delivered Duty Paid (DDP) terms.

03Orders & changes

Order reviewAccuracy check
Every purchase order is checked against our quotation. We are not responsible for changes made to a purchase order that are not reflected in the quote — including quantities, materials, colour, finishing, or newly requested documentation such as inspection reports, material certifications or CoC.
Additional quantitiesOver-production
Where production yields quantities outside the purchase order, the customer agrees to accept them at no additional cost.
CancellationWork in progress
Cancellation is free of charge until material is released to production. After release you are charged for material consumed, machine time booked and work completed to date; the amount is confirmed to you in writing and must be accepted before the cancellation is actioned.

04Fabrication basis

3D CAD governsSource of truth
Fabrication is based on the 3D CAD files you provide. 2D PDF drawings are used for reference only — tolerances, threads, surface finish and similar callouts.
Keeping drawings consistentCustomer responsibility
It is the customer's responsibility to keep the detail consistent between 2D and 3D files. Where they disagree, we build to the 3D model.
Customer-supplied dataErrors
We are not responsible for errors in customer-provided data, including misrepresented dimensions, drawing-to-CAD mismatches, last-minute changes, or broken and corrupted files.

05Lead time & delivery

Quoted lead timesFrom release
Lead times run from the later of order confirmation, payment of any deposit, and receipt of production-ready files.
Delays we are not responsible forCustomer-caused
We are not responsible for missed dates caused by customer-side delays or holds — material changes, unanswered questions on your files, hardware sourcing issues, or a requested hold. In those cases we will issue a revised delivery date for you to reflect in an updated PO.
Shipping & packagingTitle & risk
Bulk packaging is standard. Unforeseen packaging or handling costs are borne by the customer. Title and risk pass to you when the shipment is collected from our facility by the carrier, consistent with the FCA term in clause 02. We do not insure goods in transit unless the quotation says so.
Events outside our controlCarrier & supply
We are not liable for damage or delay arising from accidents, equipment breakdown, labour disputes, embargoes, supplier delays, government restrictions, civil unrest or carrier delay.

06Expedite requests

Faster lead timesOn request
We can often quote expedited lead times at your request. Additional labour, machine time and partner costs may apply.
Mid-job expeditesCost pass-through
If an expedite is requested after a job has started, the buyer agrees to assume the added cost.

07Quality, warranty & claims

We warrant that all parts are manufactured to your supplied CAD and drawings, except where noted at quoting or where a tolerance is not achievable. Here is exactly how to raise an issue.

Shortage claimsWithin 7 days
Report material shortages within 7 days of receipt of the order.
Rework & correction claimsWithin 2 weeks
Claims to rework or correct parts must be raised within 2 weeks of delivery.
Returning parts for creditBuyer's expense
To receive credit for out-of-spec or faulty parts, the buyer returns all pieces to Proleantech at their own expense.
What we always coverOur error
Where parts cannot be manufactured correctly to the supplied data, we make every effort to correct them at our own expense.
ExcludedData errors
We are not responsible for errors in customer-provided data, including mismatches between drawings and CAD files.
Claims process Send the order number, quantity affected and photos or a measurement report to quotes@proleantech.com. We acknowledge every claim within one business day.

08Payment terms

Standard termsPrepayment or NET 30
New customers and first orders are payable in advance. Established customers with a stable order and payment history are invoiced on NET 30 terms from the date of invoice. Where an order requires a deposit — for example custom tooling — the deposit amount is set out on the quotation before you place the order.
Currency & methodUSD
Quotations and invoices are issued in US dollars (USD). We accept T/T bank transfer, PayPal and major credit cards. Charges levied by the sending or an intermediary bank are borne by the customer.
Late paymentInterest
Invoices unpaid after the due date bear interest at 1.5% per month, or the highest rate permitted by applicable law if that is lower. We may suspend production, withhold shipment or decline new orders on an overdue account until the balance is settled.

09Your data, tooling & IP

Ownership of your designsYou keep it
Customer-supplied CAD, drawings and technical data remain the customer's property. We claim no licence to use them beyond fulfilling the order.
No reuseSingle-customer
We will not manufacture, replicate or resell parts from your designs for any other party.
Tooling & fixturesCustomer-owned
Tooling paid for by the customer remains your property. While we are producing parts for you we store and maintain it at our facility at no charge. Tooling can be collected or returned at any time on your written instruction, at your cost. If tooling has been inactive for more than two years we may dispose of it after giving you written notice and a reasonable opportunity to collect it.
Data deletionOn request
On request we delete production files and hold deletion records; see the Privacy Policy for retention windows.
Export controlChina and destination rules
Parts are made in and exported from mainland China, so every order is subject to Chinese export control law and to the import rules at your destination. Tell us in writing if anything on the order is export-controlled, and give us the applicable control code — a Chinese list code, an ECCN, or an equivalent. We do not accept military end-use, military end-user, ITAR-controlled or otherwise prohibited items. If a required export licence is not granted within the quoted lead time, we may cancel the affected order without liability and refund anything paid for it.

10Confidentiality

Mutual confidentialityStandard
Each party keeps the other's non-public technical and commercial information confidential and uses it only to perform the order.
Mutual NDAStandard practice
We sign customer NDAs as standard practice. Start from our mutual NDA below, or send us your own template at info@proleantech.com.

11Limitation of liability

CapOrder value
Our aggregate liability for any order is limited to the amount invoiced for that order. This cap does not apply to death or personal injury caused by our negligence, to fraud or wilful misconduct, or to any liability that cannot be limited or excluded under applicable law.
Excluded lossesIndirect
Neither party is liable for indirect or consequential loss, including lost profit, lost production or third-party penalties.

12Force majeure

Neither party is liable for failure to perform caused by events beyond its reasonable control — natural disasters, epidemic, war, sanctions, industrial action, or sustained failure of utilities or transport. The affected party notifies the other promptly and the delivery date is extended accordingly.

13Governing law & disputes

Governing lawPRC law
These terms, and any contract formed under them, are governed by the laws of the People's Republic of China, excluding its conflict-of-law rules. The United Nations Convention on Contracts for the International Sale of Goods (CISG) does not apply.
Dispute resolutionNegotiation, then SCIA
The parties will first try to settle any dispute by good-faith negotiation. If it is not settled within 30 days, the dispute is referred to the Shenzhen Court of International Arbitration (SCIA) and finally resolved by arbitration in Shenzhen, China, under the SCIA Arbitration Rules in force at the time. The seat is Shenzhen, the language is English, and the tribunal is a single arbitrator. The award is final and binding on both parties.

14Changes to these terms

Terms in force at the time you place an order govern that order. When we update this page we publish a new version number and effective date at the top, and keep the previous version available on request. We do not apply new terms retroactively to orders already in production.
