Claims, Returns & After-Sales Process

Mon, 28 Sep 2026 00:00:00 +0000

Terms Are Confirmed Per Order

Warranty period, acceptance criteria, return rights and remedies depend on the product, supplier and signed commercial terms. A universal warranty or automatic refund is not assumed unless it is written into the applicable quotation, proforma invoice or agreement.

If There Is a Problem

Order or invoice number
Product code and affected quantity
Carton, batch or label information
Clear photos and video of the goods and packaging
Measurements or test results relevant to the agreed specification
Description of installation, use and when the issue appeared
Requested temporary action and preferred resolution

Review Process

We acknowledge the claim and identify any immediate containment needed.
Evidence is checked against the approved sample, drawing, specification and shipping record.
We coordinate the investigation with the responsible supplier, inspector or logistics provider.
Findings and available remedies are discussed under the agreed order terms.
Any corrective action, replacement, credit or other resolution is recorded in writing.

Do not install or dispose of disputed goods unless safety requires it or written instructions have been agreed, as this can remove evidence needed for the investigation.

Product, Trade & Responsible Sourcing Compliance

Mon, 28 Sep 2026 00:00:00 +0000

Order-Specific Compliance

Automotive-part requirements vary by product, intended use and destination. Autopartscube does not treat one supplier certificate or a website statement as proof that every product meets every market requirement. Buyers should identify required standards, test methods, labels, substances restrictions and documents at the inquiry stage.

Evidence and Inspection

Where required and available, we coordinate supplier documents, drawings, material information, samples, measurement records, testing or third-party inspection. The quotation or order record should state which evidence is included, who provides it, which product or batch it covers and whether independent verification is required.

Cookie & Analytics Notice

Necessary Preference Storage

This site stores autopartscube-analytics-consent-v1 in your browser’s local storage to remember whether you accepted or rejected optional analytics. This preference is necessary to respect your choice and is not used for advertising.

Optional Analytics

Google Analytics is loaded only after you choose Accept analytics. The implementation denies advertising storage and personalization signals, enables IP anonymization, and is intended to measure aggregate site usage rather than build advertising profiles.

Custom Sourcing / OEM & ODM Coordination

Mon, 28 Sep 2026 00:00:00 +0000

OEM and ODM Through Suitable Manufacturing Partners

Autopartscube coordinates custom-product and private-label requests with independent manufacturing partners. Feasibility depends on the product, drawing or sample, performance requirements, quantity, tooling, target market and supplier capability.

Information to Send

Product name, current part number or OE reference
Vehicle or application details
Drawings, dimensions, tolerances or a physical sample
Material and performance requirements
Estimated order quantity and annual demand
Packaging, label and brand requirements
Destination market and any required tests or documents
Target sample and delivery dates

Typical Project Flow

Requirement review — we identify missing technical and commercial information.
Supplier matching — relevant factories are approached for feasibility and quotation.
Commercial comparison — specifications, MOQ, tooling, sample cost, lead time, packaging and trade terms are aligned.
Sample or drawing approval — the agreed reference is recorded before an order proceeds.
Order coordination — milestones and any agreed inspection are followed with the supplier.
Packing and shipment — goods are prepared and handed over under the confirmed shipping terms.

We do not describe an unverified supplier document, catalog match or prototype as final production approval. Critical fitment, performance and regulatory requirements must be confirmed for the actual project.

FAQ — Sourcing, Quotations and Orders

Mon, 28 Sep 2026 00:00:00 +0000

Company and Sourcing Model

Q: Is Autopartscube a factory?

No. Autopartscube is a trading and supply-chain integration company. We coordinate requirements with independent factories selected for the relevant product category.

Q: Can you source products not yet shown in the catalog?

Yes, subject to feasibility. Send an OE number, product photo, drawing, measurements, application, quantity and destination. A photo or catalog match is a starting point, not final fitment confirmation.

How We Work

Mon, 28 Sep 2026 00:00:00 +0000

A Trading and Supply-Chain Coordination Team

Autopartscube is an automotive-parts trading and sourcing company in Guangzhou, China. We work with independent manufacturing partners across different product categories instead of presenting every product as coming from one Autopartscube-owned factory.

What We Coordinate

Product and Supplier Matching

We organize the buyer’s OE references, photos, drawings, dimensions, materials, quantity and target market, then approach suppliers relevant to that particular product.

Specification Confirmation

Before an order is confirmed, we identify the details that affect fitment, price, packaging, lead time and risk. A catalog match is treated as a sourcing reference until the required specifications are confirmed.

Privacy Policy

Mon, 28 Sep 2026 00:00:00 +0000

Effective date: September 28, 2026

This policy applies to the Autopartscube website at autopartscube.com. Autopartscube is the trade name used on this website by an automotive-parts trading and supply-chain coordination business in Guangzhou, China. Privacy questions and data requests can be sent to info@autopartscube.com.

Information We Collect

When you submit an inquiry, we collect the information you provide, which may include your name, business email, company, phone or WhatsApp number, destination market, product or OE reference, quantity, application, message, photos or drawings sent separately, and the source page of the inquiry.

Request an Automotive Parts Quotation

Mon, 28 Sep 2026 00:00:00 +0000

Tell Us What You Need

The fastest quotations start with a clear product reference, required quantity and destination. If fitment matters, include the vehicle, engine, model year, market, dimensions, drawing or sample reference. We will identify missing details before treating a catalog match as confirmed.

Shipping & Delivery Coordination

Mon, 28 Sep 2026 00:00:00 +0000

Shipping Is Quoted for the Actual Order

Autopartscube can coordinate express, air, LCL or FCL shipping, or hand the shipment to the buyer’s nominated freight forwarder. The suitable method depends on the product, packed dimensions and weight, destination, timing, dangerous-goods status and Incoterms® 2020 rule.

Before We Quote Freight

We normally confirm:

Product and quantity
Number of cartons, pallets or crates
Estimated gross weight and dimensions
Pickup location and destination
Preferred transport method
Incoterms® 2020 rule and named place or port
Insurance, labeling or document requirements
Target shipping date

Timing

Production or order-preparation time and transport time are quoted separately. Freight schedules, customs clearance and final delivery are controlled by several parties, so any transit time is an estimate until the carrier booking is confirmed.

Website & Quotation Terms

Mon, 28 Sep 2026 00:00:00 +0000

Website Information

Catalog pages, articles, images, dimensions, cross-references and application notes are provided for sourcing and discussion. They are not a binding offer, universal fitment guarantee, installation instruction or safety certification. Critical information must be confirmed in the written quotation, approved sample, drawing or purchase-order record.

Quotations and Orders

A quotation is valid only for the product, specification, quantity, packaging, destination, currency, Incoterms®, payment terms, lead time and validity stated in that quotation. An order is accepted only through written confirmation and any required payment or agreed documentation. Website form submission alone does not create an order.
