1. Acceptance of these terms
These terms form a written contract between the buyer and the Company from the moment the buyer requests a quote, books a lot or sends a substantive order message. A buyer who places an enquiry on behalf of a business confirms that they hold authority to bind that business to these terms. A buyer who reads only the public pages without requesting anything accepts a lighter duty, simply to use the site lawfully as set out below.
The Company may update these terms from time to time. The version published on this page at the moment a lot is booked governs that particular transaction. Significant changes to the general wording are dated at the top of this page so a returning buyer can notice the difference, but a change never rewrites the terms that already locked in for an order that is already in transit.
2. Role of the Company
Liuyang Jiaoda Electronic Trading Co., Ltd. acts as an independent trading counter, not as an agent of the many makers whose parts pass across it. When the desk sources a transistor from a maker shelf, that maker sells the part to the Company, and the Company sells it onward to the buyer. The buyer therefore has a commercial relationship with the Company for the part delivered, not a direct contract with the original maker of that part.
This distinction matters for substitutions and alternative references. The Company stands behind the physical goods it ships and behind the screening it personally performs, but it does not promise that a third party maker warranty survives a resale without further agreement. Where a maker warranty can be passed on, the Company will say so plainly in writing at the time of the booking.
3. Quotes and lot numbers
A quote from the desk is an invitation, not a binding order until the buyer accepts it. Each quote carries a lot reference from the counter ledger, a list of part numbers, quantities, unit prices, a valid lead time and a date after which the offered price may change. The lot number exists so a figure can be traced back to the exact pull sheet and the exact test report behind a delivery.
A price is only fixed for the period named on the quote. Parts markets move, and a day of scarce stock can raise a cost between one quote and the next. Where the desk agrees to hold a price for a stated number of days, that hold is honoured. If a cost change would move a price after a buyer has already accepted, the Company notifies the buyer before dispatch and the buyer can accept the new figure or cancel without penalty.
4. Placing an order
An order is complete once the buyer accepts a written quote, the lot number is confirmed and the payment or deposit conditions are agreed. A purchase order sent by the buyer counts as an offer until the desk confirms a matching acceptance. A simple message asking for availability is not an order and creates only the duty to answer the question truthfully.
Orders can be raised for a single rare component, a full production quantity or a pre-booked pull that the desk secures from stock. Once a lot is pulled and graded to a buyer name, it becomes harder to cancel without cost, because parts already allocated cannot be sold twice. If a buyer cancels after the bench has finished the pull, the desk may charge a reasonable restocking portion as described in the quote.
5. Pricing and payments
All prices on the site are listed in the way the order confirms, and the quote shows the currency and whether trade, tax or freight charges are included. Local taxes, import duties and carrier fees that a destination country adds are usually the buyer responsibility unless the booking note states otherwise in writing. The buyer should read the delivery line of the quote before paying.
The Company accepts the payment methods named on the accepted quote, which commonly include bank transfer and agreed trade channels. Full payment or an agreed deposit must clear before sealed lots leave the counter, unless a long-standing buyer has an approved credit line on file. Interest on a late invoice is charged only if it is stated on that invoice and allowed by the law that governs the order.
6. Shipping and delivery
Delivery is arranged from the Company logistics desk in Changsha to the destination named by the buyer on the order. A lead time written on a quote is quoted in working days from the moment payment clears and stock is confirmed, unless a longer sourcing cycle for a rare reference was already disclosed. Delays caused by a carrier or by customs are outside the Company control but are tracked and reported openly.
Risk passes to the buyer at the point the shipping terms on the accepted quote say it does. To keep a delivery clear at a border, the buyer must provide a complete and correct delivery address and any import reference numbers the destination country expects. Where the buyer asks the Company to split shipments or to hold a lot, extra handling can attract a small fee that is agreed before the split happens.
7. Quality and substitution
Before any lot is sealed, the bench pulls, inspects, tests, grades and packs the stock as described on the services page. This screening is a genuine service with real checks, but it is not identical to the full qualification a chip maker performs on every thousand units. A buyer who needs a full reliability qualification should say so on the order so the desk can quote the deeper test program as a separate service.
Where a requested reference is obsolete, the desk may propose a cross-referenced substitute. A substitute is always disclosed in writing and the buyer approval must be given before that substitute is packed. A substitution made without approval gives the buyer the right to reject the lot. No substitute is offered where a genuine direct replacement cannot be found and marked clearly on the pull sheet.
8. Returns and claims
If a delivered lot is damaged in transit, arrives with the wrong part or fails the check the buyer explicitly ordered, the buyer should raise a claim within the period named on the quote, usually seven days from receipt of the goods. A claim must include the lot number, a photo or description of the issue and the delivery note, so the desk can trace the pull sheet and the same production run.
For a valid claim, the Company will repair, replace, re-screen or refund in a way that the buyer and desk agree. No claim is accepted after the part has been reworked, desoldered or modified by the buyer, because the evidence trail is then broken. A buyer who returns goods without prior agreement takes responsibility for packing them well and for the condition they arrive in.
9. Warranty and liability
The Company warrants that the parts it ships are of the kind described on the accepted quote and conform to the grading noted at the bench. This warranty runs for the period named on the quote, and for no longer than the maker original warranty where that is shorter. The warranty does not cover parts damaged by misuse, wrong polarity, overvoltage, heat beyond rating or careless soldering once they reach the buyer bench.
Liability is limited in the way described later in these terms. In no case does the Company accept liability for a loss of production, a loss of profit, a rendered board lot, or a ripple failure in a buyer finished product caused by a single defective component, beyond the value of the parts in that particular claimed lot. Buyers who run safety critical or mission critical systems must apply their own qualification on top of any screening purchased here.
10. Ownership and marking
Ownership of the physical parts transfers to the buyer when the price for those parts is fully paid and the goods are dispatched under the agreed shipping terms, whichever event the shipping term names as the moment of transfer. Before that point, the parts remain the property of the Company and the buyer has no right to resell, relabel or register them as its own.
The buyer does not obtain any right to the maker trademarks or the Company trademarks simply by buying parts. Rebuilding a part to look like a branded original and selling it as that original is forbidden and is a clear breach of these terms and of the trademark laws that protect the marker. Any such misuse ends the buyer right to buy from the counter and leaves the responsibility fully with the buyer.
11. Confidential information
A bill of materials reveals production plans, so the Company treats it as confidential commercial material. BOM files, reference lists, build quantities and internal codes sent to the desk are not shared with competitors, not used to build rival products and not posted anywhere public. This duty continues after a finished transaction and lasts as long as the information stays genuinely secret.
The same duty runs in the other direction. Prices, lot allocations, source names and bench methods that the Company shares in confidence must stay within the buyer organisation. If the buyer belongs to a larger group, the information stays with the buyer entity unless another group entity is already part of the same active order file. Every party protects the trust that any counter relationship depends on.
12. Export and trade compliance
Electronic components travel through rules that change by country and by part family. The buyer is responsible for satisfying itself that the parts it orders can lawfully enter its own territory and be used in its own products, and that its own end use does not break any sanction or export control regime that applies. The Company will not knowingly supply parts that would be shipped into an embargoed destination.
The desk will not help a buyer disguise a destination, misdeclare goods on customs forms or sidestep a legal requirement. Where documented support is needed to ship a compliant lot, the Company prepares that paperwork as a service. If a rule that applied when the order was accepted changes before dispatch, the Company will tell the buyer and either adjust the plan lawfully or cancel the affected part of the order.
13. Site content and accuracy
The catalogue, service descriptions and process explanations on this site are prepared with care and reviewed at the bench. Figures such as screening methods, lot counts and bench routines describe the way the counter normally works. They are given as a helpful guide and do not form a binding promise about every single future transaction unless a specific order repeats the point in writing.
Occasional human or source error in a datasheet figure is possible, and the desk corrects such a slip as soon as it is found. Where content relies on an outside standard or maker note, the reader should confirm against the maker own published data before deciding. Reporting a real error to the desk helps keep the pages honest and is treated as a favour rather than a complaint.
14. Acceptable conduct
This site exists to help honest makers and buyers find parts. Using it for fraud, reselling a screened lot as factory new without disclosure, sending harmful software through a form, overloading the pages to attack the server, or misusing the contact details to send spam is forbidden. The Company may block any user who breaks these rules and may report serious misuse to the relevant authorities.
Quoting, reserving and then abandoning lots without notice also disappoints other buyers who wanted the same shelf. A buyer who repeatedly reserves genuine stock and never completes it will find later reservations require pre-payment. This is not a punishment; it simply keeps rare parts moving to the people who will actually build with them.
15. Intellectual property
The text, layout, labels, drawing style and the parts-wall presentation of this site are the intellectual property of the Company and are protected as such. Any diagram used on the services page to illustrate the bench run is provided to explain a process, not as a licence to copy the page design for a competing site or to reproduce the Company trade dress.
A buffer may copy a short quote for a genuine review or to reference the Company, but wholesale reuse of the page structure, the brand marks or the content without written permission breaches these terms. Nothing in these terms transfers any mark or ownership. The JiaoDa brand and the assembled design of this counter are used here to identify the supplier that operates the service.
16. Limitation of liability
To the fullest extent the governing law allows, the Company total liability arising from any single order is limited to the amount the buyer actually paid for the parts in that order. This cap covers all forms of loss together, whether the claim is made in contract, in negligence or under a consumer protection rule where that rule permits a cap at all.
The Company is not liable for indirect or consequential loss such as lost production, lost trade, lost profit, loss of data or the cost of replacing buyer finished stock that fails because of a defect the bench could not reasonably have detected. Where local law will not let a seller exclude consequential loss, the exclusion shrinks to the maximum extent that law allows and every other part of these terms stays in force.
17. Governing law and disputes
The rules that govern these terms depend on where an order is accepted. For an order accepted by the desk at its registered base, the law of the People Republic of China governs the relationship unless a specific order names another jurisdiction. Courts or recognised arbitration in a contractually agreed seat decide a dispute that cannot be settled by conversation.
Before any court step, the desk asks that both sides try a fair exchange of the facts, because most component disputes are really a missing test report or a misread lead time that a calm conversation solves. Neither side gives away a right to proper legal process by having that conversation. A prevailing buyer or seller can claim reasonable costs only where a court or a rule of law so directs.
18. Termination of a relationship
Either party may stop working together with notice, without hurting orders that are already sealed and in transit. An order accepted before the notice keeps running under the terms that applied when it was accepted, because pulling a tray out from under a shipment that is already moving would harm the buyer for no fault of its own.
The Company may end its service to a buyer who breaks these terms, fails to pay a due invoice, or acts in a way that damages the trust of other buyers. Ending the relationship does not cancel a debt already owed and does not release either side from the confidentiality duties that survive as set out earlier. A buyer can stop using the counter at any time by simply not placing new business.
