Custom SPD Order Checklist: 8 Things to Confirm Before Placing a Bulk Order
Placing a first bulk order with a new SPD manufacturer involves more variables than standard product procurement. Custom branding, specific certification requirements, packaging specifications, and IP arrangements all need to be agreed in writing before production begins โ not discovered mid-production or at goods inspection.
This checklist covers the eight areas where misaligned expectations most commonly cause delays, cost overruns, or disputes. Work through each item before issuing a purchase order.
The Checklist
What to confirm:
- Which certifications apply to your target market? (CE for Europe, IEC 61643-11 test reports for global B2B, UL 1449 for North America)
- Does the supplier hold current, valid certificates โ not expired or under a previous company name?
- Are the certificates issued under the exact model number you are ordering, or a base model that differs from your customized version?
Why it matters:
Custom SPDs with modified housing, terminal configuration, or branding may require re-testing or a separate certificate extension depending on the certification body's rules. Confirming this before ordering avoids discovering at customs clearance that your customized unit is not covered by the supplier's existing certificate.
What to request:
Original certificate documents (PDF, not scanned copies) and the corresponding IEC 61643-11 test report from an accredited laboratory. For CE-marked products, also request the Declaration of Conformity.
What to confirm:
- What is the minimum order quantity for standard products?
- What is the MOQ for custom-branded or custom-configured products?
- Are orders placed in fixed increments (e.g., per carton or per pallet quantity)?
- What is the MOQ for re-orders after the initial run?
Why it matters:
MOQ for custom products is almost always higher than for standard stock, because tooling, screening setup, and production scheduling have a fixed cost that needs to be spread across a viable run quantity. Suppliers who accept unusually small custom MOQs may be quoting from existing stock with surface-level customization rather than genuine production.
TrilPeak standard terms: Minimum order quantity for custom-branded SPDs starts from 1,000 units per model. Sample orders: minimum 5 units, processed within 7 business days.
What to confirm:
- What is the standard retail and master carton configuration (units per inner box, inner boxes per master carton)?
- Can packaging be customized with your branding, language, or regulatory markings?
- What are the dimensions and gross weight of master cartons? (Required for freight calculation)
- Are there specific packaging requirements for your market โ e.g., bilingual labeling, country-of-origin marking, recycling symbols?
Why it matters:
Packaging errors โ wrong language, missing regulatory marks, or carton sizes incompatible with your warehouse racking โ are discovered at delivery and cannot be corrected without a full repack. This is one of the most common sources of invoice disputes on first orders with a new supplier.
What to request:
A sample of the proposed packaging before production, or at minimum, a print-ready proof of all label artwork for sign-off.
What to confirm:
- What payment terms does the supplier offer? (T/T advance, 30% deposit + 70% before shipment, L/C at sight)
- What currency is accepted?
- Is escrow or a letter of credit available for first orders?
- What are the bank charges and transfer fee responsibilities?
Why it matters:
Payment terms directly affect your cash flow on large orders. A 100% advance payment on a $50,000 order with a new supplier carries meaningful risk. Most established manufacturers will accept a 30% deposit with balance payable against shipping documents or a copy of the bill of lading โ this structure protects both parties.
What to request:
Payment terms stated explicitly in the proforma invoice or purchase agreement, not only in email correspondence.
What to confirm:
- Are pre-production samples (golden samples) provided before bulk production begins?
- Is there a sample charge, and is it refundable against the bulk order?
- What is the sample lead time?
- Who has approval authority โ can you sign off remotely, or is an in-person factory visit required?
Why it matters:
A golden sample is the reference standard against which every unit in the production run should be measured. Without an approved sample on file, "to spec" becomes a matter of interpretation. This is especially important for custom-branded products where color matching, label placement, and housing finish need to be confirmed before 5,000 units are molded.
TrilPeak standard terms: Sample lead time 5โ7 business days. Sample charge applies; credited in full against bulk order payment.
What to confirm:
- Will the supplier sign a Non-Disclosure Agreement (NDA) before design discussions begin?
- Will custom molds, tooling, or firmware created for your product be owned exclusively by you?
- Will the supplier manufacture the same product under their own brand or supply it to your competitors?
- Is tooling cost included in the unit price or quoted separately?
Why it matters:
For ODM projects with custom housing or circuit design, the IP arrangements need to be documented before any design work begins โ not negotiated afterward when the tooling already exists. Mold exclusivity agreements and market exclusivity clauses (by region or by customer type) are standard in B2B OEM/ODM contracts with established manufacturers.
What to request:
A signed NDA before sharing any design files, brand guidelines, or product specifications. A tooling ownership clause in the purchase agreement.
What to confirm:
- What Incoterms apply? (EXW, FOB, CIF โ each transfers risk at a different point)
- What is the confirmed production lead time from PO to ready-to-ship?
- What is the supplier's on-time delivery rate? Can they provide references?
- Are there penalties for late delivery, and are they enforceable?
- What port of loading is used?
Why it matters:
"Lead time" quoted informally in sales conversations often means production time only, excluding the time to book freight, complete export documentation, and clear customs. For project-based procurement with an installation deadline, the complete door-to-door timeline must be calculated before committing to a delivery date to your customer.
Standard lead times for reference:
Sample / prototype: 5โ7 business days. Standard production run (1,000โ5,000 units): 15โ20 business days after deposit received and golden sample approved. Large volumes or fully custom designs: confirm separately.
What to confirm:
- Does the supplier permit third-party pre-shipment inspection (PSI)?
- Which inspection agencies does the supplier work with (SGS, Bureau Veritas, Intertek, others)?
- What inspection standard applies โ AQL 1.0, 1.5, or 2.5?
- Who bears the cost of inspection and re-inspection if failures are found?
- What is the supplier's process when out-of-spec units are found during inspection?
Why it matters:
Pre-shipment inspection is the last point at which quality problems can be resolved before goods leave the factory. Suppliers who refuse third-party inspection or who cannot specify an inspection standard should be treated as a significant procurement risk. AQL 2.5 is typical for industrial components; AQL 1.0 or 1.5 is appropriate for products where end-customer safety is a direct concern, as is the case with surge protective devices.
What to request:
Written confirmation that third-party PSI is permitted. A defined re-inspection process and a clear statement of responsibility if the batch fails inspection.

Before You Send the Purchase Order
All eight items should be confirmed in writing โ in the purchase agreement, proforma invoice, or a signed supplier questionnaire โ before the PO is issued. Verbal confirmations and email assurances are not enforceable if a dispute arises after payment.
For suppliers you are working with for the first time, consider using a two-stage process: a small initial order (sample or trial quantity) with full documentation, followed by the bulk order once quality and process have been verified. The additional lead time is consistently less costly than resolving a failed inspection on a large shipment.
T/T (Telegraphic Transfer) is the standard payment method. A 30% deposit with the balance payable before shipment or against the bill of lading is the most widely used structure for first orders โ it protects both parties. 100% advance payment on a large first order with a new supplier carries meaningful risk. Note: Letter of Credit (L/C) may be required in certain markets or for specific project types; confirm with the supplier whether this is supported.
The supplier should produce a pre-production sample for your sign-off before bulk production begins. The approval process should confirm colour, finish, label placement, housing dimensions, and electrical parameters. The signed-off sample should be retained by the supplier for the duration of the supply relationship as the reference standard.
FOB (Free on Board) is common for first orders โ risk transfers at the origin port and you control the freight booking. CIF (Cost, Insurance, Freight) includes freight and insurance in the quoted price but gives you less visibility on costs. Always confirm the port of loading.
Ask explicitly whether your customised or branded version is covered by the existing certificate, or whether it requires a separate certificate extension. A base model certificate does not automatically extend to variants with modified terminal configurations, protection modes, or packaging.
AQL 1.5 or 1.0 is recommended for safety-critical components like surge protective devices, where end-customer safety is directly at stake. AQL 2.5 is the minimum acceptable level. Confirm the AQL standard in writing before the order is placed.
