How to Source Lubricants and Auto Parts: A B2B Buyer’s Guide

Who should use this guide — and how is RFQ sourcing different from buying online?

This guide is written for procurement managers, importers, distributors, wholesalers, and fleet operators who need to source lubricants or automotive parts in commercial volumes — either across borders (export channel) or within a local market. If you have ever bought a product on a consumer website, RFQ sourcing works very differently, and understanding that difference is the first step to using any B2B trade platform effectively.

When you buy online as a consumer, the price is fixed, the seller is identified, and the transaction is completed on the platform. RFQ-based B2B sourcing reverses that logic. You describe what you need — quantity, specification, destination, terms — and registered suppliers respond with offers tailored to your requirement. The negotiation, sampling, documentation, contracting, and payment all happen directly between you and the supplier. The platform’s role is discovery and introduction, not transaction processing.

This matters for lubricants and auto parts in particular because the same product family — say a SAE 15W-40 engine oil — can vary significantly in API category, additive package, pack format, container type, Incoterm, and export documentation. A fixed-price cart cannot capture that complexity. An RFQ can. For buyers sourcing at pallet, drum, or container scale, the RFQ model gives you control, comparability, and a direct supplier relationship that consumer e-commerce cannot offer.

How do I find the right supplier on Altonex Global?

Effective sourcing starts with targeted discovery — not browsing at random. Altonex Global offers several complementary discovery paths, and using them together produces a sharper shortlist than any single route.

Primary discovery routes:

• Supplier directory: the Altonex Global supplier directory lists registered suppliers with their company profiles, product families, and declared channels (export, local, or both). Start here when you need to evaluate supplier capability before looking at individual products.
• Product categories: browse by product type — Automotive Lubricants, Industrial Lubricants, Specialty Lubricants, Marine Lubricants, Greases, and auto parts categories including filters, brake pads, batteries, spark plugs, and tires. This path is most useful when you know the product type but not yet the supplier.
• Keyword search and on-site filters: use filters for viscosity grade (e.g. SAE 10W-40, 15W-40, ISO VG 46), API or ACEA specification, pack size (from 1 L bottles to 1000 L IBCs), and Incoterm. Filters let you eliminate suppliers who cannot meet your technical or commercial baseline before you invest time in reading a booth.
• RFQ Center: if you have a sourcing requirement but are not yet sure which supplier to approach, post it on the RFQ Center. Registered suppliers who match your requirement can see the posting and respond — your contact details remain private on the board.

A disciplined B2B buyer shortlists six to eight suppliers, not fifty. A very long list produces unmanageable quote comparison and signals to suppliers that you are not a serious buyer. Use the filters and the supplier profile to qualify before you contact, and contact only those whose product range, volume capability, and export history match your requirement.

How do I read a supplier booth and a product listing?

A supplier booth on Altonex Global is the digital equivalent of an exhibitor stand at a trade expo. Reading it carefully before sending an RFQ saves time and avoids mispriced or off-specification quotes.

What a supplier booth shows:

• Company profile: the supplier’s background, manufacturing or distribution capability, geographic reach, and the channels they serve (export, local, or both).
• Certifications declared by the supplier: ISO 9001, API licence, ACEA approval letters, and other quality credentials the supplier chooses to display. These are self-declared; Altonex Global does not independently audit them — you should verify directly with the issuing body for any certification that is critical to your supply chain.
• Product catalogue: the full range the supplier lists, navigable by family or category.

What a product listing shows:

• Technical specifications: viscosity grade (e.g. SAE 5W-30), API service category (e.g. API SP or SQ for gasoline engines, CK-4 for heavy-duty diesel), ACEA category (e.g. ACEA C3, E9), JASO grade for motorcycle oils (e.g. JASO MA2), or ILSAC classification — and for parts, OE cross-reference numbers, friction standards (e.g. ECE R90 for brake friction), or WVA codes.
• Pack sizes and trade units: 1 L, 4 L, 5 L, 20 L pail, 208 L drum, 1000 L IBC — and the indicative minimum order quantity (MOQ) for each format.
• Indicative price: a reference figure for planning purposes only. It is not a final price, not a confirmed offer, and cannot be purchased on the platform. The actual price is agreed directly with the supplier via RFQ.
• Incoterms offered: which delivery terms the supplier declares (e.g. FOB, CIF, DDP). This tells you immediately how much of the logistics chain the supplier will manage.
• Channel: whether this product is offered for export, for a local market, or both. Local availability is being introduced progressively — where it appears on a listing, it means the supplier has declared in-country availability for that market.

The indicative price and indicative MOQ shown on a listing are the supplier’s opening reference point — treat them the same way you would treat a price on an expo product card, not a confirmed invoice line. Your negotiated terms may differ based on volume, payment method, destination, and timing.

How do I write an RFQ that gets a fast, useful response?

A well-written RFQ is the single highest-leverage action a buyer can take. Specific, complete RFQs consistently produce faster responses and more comparable quotes than vague ones, because the supplier can price without coming back for clarification. An RFQ sent via the RFQ Center or from a product page should include all of the following.

RFQ components — include all of these:

• Company introduction: one or two sentences on who you are, your business type (importer, distributor, fleet operator), and your market. Suppliers prioritize buyers who introduce themselves — it signals seriousness and gives context for how they price.
• Exact product specification: for lubricants, state the viscosity grade (SAE J300 notation, e.g. SAE 15W-40 or SAE 5W-40), the API service category (e.g. API CK-4), the ACEA category if required (e.g. ACEA E9), and any OEM approval letters required (state generically — e.g. “approval for [your OEM model range]”). For auto parts, state the OE part number, the cross-reference standard, and the vehicle application. Specify the brand if you need a specific branded product — or state “equivalent specification accepted” if you are open to alternatives.
• Quantity and pack format: state volume (litres or units) and the packaging format you require (e.g. 208 L drums, 1000 L IBCs, pallet of 4 L bottles). Quantity directly drives the supplier’s MOQ logic and freight calculation.
• Destination: country and port of destination. This is needed for the supplier to quote a landed-cost-relevant Incoterm and for export documentation (HS code, certificate of origin).
• Preferred Incoterm: state the Incoterm under which you want the quote (see the table below). If you are open to more than one, say so — but ask for a single Incoterm quote per supplier so you can compare like-for-like.
• Required certifications and documents: list what you need (CoA, SDS, certificate of origin, ISO 9001, API licence, brand authorization letter). This prevents a situation where you receive a competitive quote only to discover the supplier cannot produce the documentation your customs authority or quality system requires.
• Required delivery date (or lead time): give a realistic date. A tight, unachievable deadline disqualifies suppliers unnecessarily; too vague a timeline lowers your urgency signal.
• Payment terms preference: state your preferred structure (e.g. 30% advance T/T, 70% against B/L; or L/C at sight). This is not binding at RFQ stage but saves a separate clarification round.
• Response deadline: give suppliers a clear date by which you need a reply (typically five to ten business days for export quotes). This drives action and helps you manage your shortlist process.

Incoterms 2020 — buyer’s quick reference:

The critical discipline when comparing quotes from multiple suppliers: normalize all quotes to the same Incoterm and compare landed cost (unit price + freight + insurance + import duties + clearance fees), not unit price alone. A lower unit price under EXW frequently becomes a higher landed cost once you add international freight from the origin factory.

How do I evaluate and qualify a supplier before committing?

Receiving a competitive quote is a starting point, not a decision. Before committing to a first order with any new supplier, apply a structured qualification process. The cost of a due-diligence step is always lower than the cost of a failed shipment, a substandard product, or a trade-finance dispute.

Documents to request and how to verify them:

• Certificate of Analysis (CoA): batch-specific quality and analysis data for the lot you are buying. It should reference a specific batch or lot number, not be a generic marketing sheet. Compare the CoA values against the product’s published TDS (Technical Data Sheet) — they should align.
• Safety Data Sheet (SDS / MSDS): required for the transport and import of lubricants under most jurisdictions (GHS-compliant, 16-section format). Without a current SDS for the specific product, the shipment may be blocked at customs or rejected by a freight forwarder’s dangerous-goods team.
• Technical Data Sheet (TDS): the published performance specifications. Use this to cross-check the CoA and to confirm the product meets your application requirement.
• Certificate of Origin: required for customs clearance in most destinations; it also determines preferential duty rates under applicable free-trade agreements. Confirm the origin declared matches the manufacturer’s actual country of production.
• ISO 9001 certificate: confirms the supplier operates a documented quality management system. Verify the certificate is current, covers the relevant product scope, and was issued by an accredited certification body.
• API licence (for API-marked engine oils): API licences are specific to the product brand, viscosity grade, and service category. Verify any claimed API licence at api.org using the licence number on the certificate. A fake or expired API licence is a significant counterfeit-product risk signal.
• Brand authorization letter (if the supplier sells a brand they do not manufacture): a distributor or reseller should be able to produce a current, dated authorization letter from the brand owner. Where a brand is involved, contact the brand owner directly to confirm the supplier’s current authorized-distributor status.

Additional qualification steps for a new supplier relationship:

• Verify business registration: request the supplier’s official company registration certificate and trade licence. This is standard practice in international trade, and a legitimate supplier will expect it.
• Request export references: ask for references from buyers in your destination country or region. A supplier with genuine export experience will have them; inability to provide any reference for an established export destination is a flag.
• Conduct a facility video call: for significant volumes, request a video tour of the production or warehousing facility. This is now standard practice in B2B sourcing and costs nothing.
• Treat below-market pricing as a red flag: if a quote comes in well below the market reference level for the specification and volume — experienced buyers often treat a discount of roughly 20% or more under comparable quotes as a warning rather than a bargain — it warrants additional scrutiny before proceeding. Counterfeit lubricants and substandard parts are a documented risk in international trade; suspiciously low pricing is one of the consistent early signals.
• Request a batch-traceable sample: for a new supplier relationship, always request a sample referenced to a specific lot number before committing to a full order. Have the sample tested by an independent laboratory against the CoA and TDS.

What happens after I send an RFQ — and how does negotiation work?

Once you submit an RFQ — whether from a product page, from the RFQ Center, or via the RFQ Board — it routes directly to the supplier. Altonex Global retains an internal record for platform purposes only, but does not intermediate, modify, invoice, participate in the exchange, or play any role in resolving disputes between a buyer and a supplier. Everything that follows is between you and the supplier.

Typical sequence after an RFQ is sent:

• Supplier acknowledgement: a well-structured supplier will acknowledge receipt and confirm a response timeline within one to two business days. If there is no acknowledgement after three business days, a follow-up is appropriate.
• Quotation received: the supplier sends a formal quotation (proforma invoice or commercial offer) with unit price, MOQ, Incoterm, validity period, payment terms, lead time, and included documentation. Compare quotations from your shortlist on a normalized landed-cost basis, not unit-price alone (see the Incoterms table above).
• Clarification and counter-proposal: B2B quotations are an opening position. It is entirely normal to counter on price, MOQ, payment terms, or pack format. Provide a written counter rather than a verbal one — it creates a traceable record.
• Sampling and lab testing: for first-time orders, agree a sample shipment before committing to container quantities. A pre-shipment sample referenced to the production lot, tested by your own laboratory or an independent third party (e.g. Bureau Veritas, SGS, Intertek) against the CoA and TDS, is the strongest quality assurance step available at this stage.
• Pre-shipment inspection: for larger orders or when shipping to a destination with strict import regulations, consider commissioning a third-party pre-shipment inspection (PSI). The inspection agency confirms product specification, quantity, packing, and labelling before the consignment loads.
• Contract and payment: once terms are agreed, the contract and payment are arranged directly between you and the supplier. Common structures for a first order with a new supplier include a letter of credit (L/C) for strong buyer protection, or a split T/T (e.g. 30% deposit, 70% against copy B/L). These are between the buyer, the supplier, and their respective banks — Altonex Global is not a party.

After an order is placed, the full trade documentation package — commercial invoice, packing list, bill of lading, CoA, SDS, certificate of origin, and any destination-specific import permits — flows between the supplier, your freight forwarder, and your customs broker. Altonex Global does not handle, store, or co-sign any of these documents.

What is the difference between export sourcing and local sourcing?

Altonex Global supports two sourcing channels: export and local. Understanding which applies to your situation shapes how you filter suppliers, what documents you request, and how you compare quotes.

Export channel — cross-border sourcing:

• The supplier ships across an international border to your destination country or port.
• Pricing is typically quoted in USD on a per-Incoterm basis; indicative tier ladders (per container, per drum, per pallet) give a planning reference.
• Full export documentation applies: CoA, SDS, certificate of origin, HS code classification, and any destination-country import permits or conformity certificates required for lubricants or auto parts.
• Confirm the HS code for your product with a licensed customs broker in your destination country before finalizing the order — misclassification is a common and correctable source of customs delay.
• Commercial payment structures typical for export (T/T, L/C, D/P, D/A, Open Account depending on relationship and country risk) apply here.

Local channel — in-country supply:

• Where a supplier declares local availability, the listing will show local-channel information: in-country indicative pricing, local MOQ, and local delivery terms.
• Local channel sourcing is being introduced progressively on Altonex Global. Where it appears on a listing, it means the supplier has declared local in-country availability for that market — always confirm current availability directly with the supplier via RFQ.
• Even for local supply, the RFQ model applies: the indicative price on the listing is a display-only reference, not a final offer. All terms are agreed directly between you and the supplier.
• Documentation for local supply will differ from export documentation — it typically covers local delivery terms, in-country quality certificates where required, and local commercial terms rather than international trade-finance instruments.

Whether you source export or local, the platform’s role is the same: discovery and RFQ introduction. The deal is concluded off-platform, directly with the supplier, under whichever channel terms apply to your requirement.

What does Altonex Global do — and not do? (trust and safety)

Altonex Global is a B2B trade platform operated by Altonex Global Trading, headquartered in the UAE. Understanding precisely what the platform does and does not do helps you calibrate your own due-diligence responsibilities as a buyer.

What Altonex Global does:

• Provides a structured supplier directory and product catalogue for discovery of registered lubricant and auto-parts suppliers worldwide.
• Hosts supplier booth pages where suppliers present their company profile, product range, declared certifications, and channel information.
• Routes RFQs from buyers to the relevant supplier, retaining an internal oversight copy.
• Maintains brand and trademark records: registered suppliers declare brand ownership or distributor authorization and submit supporting documents during registration. These records are held internally.
• Provides the RFQ Center and RFQ Board as structured tools for buyer sourcing requirements.
• Publishes the Knowledge Hub, including technical sourcing guides, lubricant specification articles, and the supplier guide that accompanies this buyer’s guide.

What Altonex Global does not do:

• Does not sell, buy, manufacture, store, or ship any product. Altonex Global is not the seller in any transaction.
• Does not independently verify, audit, or guarantee the accuracy of supplier-declared certifications, product specifications, or company information. Buyer due diligence remains entirely the buyer’s responsibility.
• Does not process payment, hold funds, operate escrow, or provide trade-finance services. All payment is between the buyer and the supplier.
• Does not arrange freight, shipping, or customs clearance, and is not a party to any shipping contract.
• Does not take a commission or fee from any transaction between a buyer and a supplier.
• Does not intermediate, invoice, or co-sign any trade documentation.

Suppliers on the platform are registered suppliers — they have completed the platform’s registration process, which includes declaring brand authorization or ownership, submitting company information, and listing products under their own account. Registration is a compliance and identification step; it is not a guarantee of product quality, financial standing, or export capability. Conduct your own due diligence on any supplier you intend to trade with, following the qualification steps outlined in this guide.

If you have a sourcing requirement and are ready to begin, the RFQ Center is the right starting point. Browse the supplier directory to identify your shortlist, review the booth pages and product listings for each, and submit targeted RFQs with the specification, quantity, and terms detail outlined in this guide. Related guidance, including technical lubricant specification articles and our supplier-facing guide, is available in the Knowledge Hub.
