Back to the Polysilicon: Supplier and Procurement Standards That Reach Three Tiers Down for a Composite Solar Cold Room Project Buying in Four Countries
Why Suppliers Decide Whether Commitments Hold
Brightwell Cooling, the composite Columbus company in this course, will put solar cold rooms into service for 40 Kenyan growers' groups using parts and services bought from firms it does not control. The sustainability plan committed the project to a propane refrigerant, battery take-back and a Kenyan labor share, and the grant agreement requires that no part of the project benefit from forced labor. Every one of those commitments is carried out by a supplier. This document states what the project requires of the firms it buys from, how far down the supply chain each requirement reaches, what evidence counts as proof and what happens when an audit finds a breach.
Villena and Gioia (2020) studied multinational companies with strong sustainability commitments and found that their lower-tier suppliers frequently violated those standards, often because the buying firm checked only its direct suppliers. Tachizawa and Wong (2014), reviewing research on multi-tier supply chains, describe the choice a buyer faces between managing lower tiers directly, working through its first-tier suppliers, or leaving them unmanaged. This project cannot manage every tier, so it chooses by risk.
The Suppliers and Their Risks
Six suppliers or supply categories carry the project's commitments.
| Supplier | Tier | What it provides | Main risk to the commitments |
|---|---|---|---|
| Monterrey contract manufacturer | 1 | Assembly of all cold rooms | Labor conditions; refrigerant handling; export compliance |
| Photovoltaic module supplier | 1, with tiers 2 and 3 below | Solar panels | Forced labor in polysilicon production |
| Lithium iron phosphate battery supplier | 1, with cell maker at tier 2 | Battery packs | Mineral sourcing; end-of-life handling |
| Compressor and refrigeration unit supplier | 1 | Propane compressors and units | Substitution of a hydrofluorocarbon unit when stock runs short |
| Nairobi installation partner | 1 | Installation and service | Worker safety; licensing; labor share records |
| Freight forwarder | 1 | Sea freight and clearance | Air freight substitution; documentation |
How Far Down Each Requirement Reaches
Most requirements stop at the first tier, because the direct supplier controls the risk. The Monterrey manufacturer, the installer and the forwarder are held to the standards themselves and audited directly.
Two requirements reach further. For solar panels, the forced labor requirement reaches three tiers down, to the polysilicon from which the cells are made. A large share of the world's polysilicon has come from China's Xinjiang region, where forced labor has been widely documented, and United States law presumes that goods made wholly or partly there were made with forced labor and bars their import unless the importer proves otherwise (Uyghur Forced Labor Prevention Act, 2021). The panels in this project go from Mexico to Kenya and never enter the United States, so the law does not apply to them directly. The project applies its standard anyway: the funder is a US program, the requirement is in the grant, and a panel that would be barred from the United States should not be bought with US funds.
For batteries, the requirement reaches the cell maker at tier 2, because the take-back commitment depends on knowing the cell chemistry and maker, and because recyclers need that information to process cells safely.
What Counts as Evidence
A signed supplier code of conduct is required from every supplier but counts as no evidence at all, since signing costs nothing. The evidence the project accepts is set out by requirement.
For polysilicon origin, the module supplier must provide chain-of-custody documents linking the specific production batch of panels to the cell maker, the wafer maker and the polysilicon producer, with the producer's location. Panels without complete documents are not accepted, whatever their price.
For labor conditions at the Monterrey plant and the installer, the evidence is an independent social audit by an auditor the supplier does not choose alone, plus Brightwell's own site visit. The Monterrey audit is scheduled for August, before the peak assembly months.
For the refrigerant, the evidence is the compressor supplier's model and serial record matched to each commissioning record. For batteries, it is the cell maker's declaration of chemistry and a registered serial number per pack. For the installer's labor share and licensing, it is timesheets and license numbers checked against the regulator's public register.
Buying Decisions the Standards Have Already Changed
The standards are not only a checklist for later audits; they changed two purchases before any order was placed. The lowest of three panel quotes, about $4,200 below the next across the project, came from a supplier that could document its cells and wafers but not the origin of its polysilicon. It was declined, and the second quote was accepted with full chain-of-custody documents. The compressor supplier was asked to hold a buffer of propane units for the project in its own warehouse, at a cost of about $1,500, after it admitted that in a past shortage it had shipped hydrofluorocarbon units to other customers without warning. Both costs are recorded against the sustainability line of the budget, so the price of keeping the commitments is visible rather than hidden in unit prices.
When an Audit Finds a Breach
Breaches are graded, because treating every finding as grounds for termination would push suppliers to hide problems. Minor findings, such as missing training records, require a corrective plan within 30 days and are rechecked at the next visit. Serious findings, such as unsafe refrigerant handling or unpaid overtime, require correction within 14 days; payments for affected work are held until a follow-up visit confirms the fix. Any evidence of forced labor, at any tier, leads to immediate suspension of purchases from that supplier and removal of affected goods from the project, with the cost borne under the supply contract. A supplier that discloses a problem it found itself is treated one grade more leniently than one whose problem is found by an audit, which rewards the honesty the project depends on.
Each of these consequences is written into the purchase contracts before orders are placed, since a standard added after signing cannot be enforced. Brightwell, its suppliers and every term here are composites for this course.

Reading the BU 436 Unit 6 instructions
In the sixth unit, BU 436 asks students to write procurement standards that carry a project's sustainability and ethical commitments into its supply chain. Prompts usually require identifying suppliers and their risks, stating requirements, deciding how many tiers each requirement reaches, defining acceptable evidence and setting consequences for breaches. Many instructors ask whether suppliers should hold named certifications and how audits will be conducted. Students are expected to explain why depth differs between requirements and to connect each standard to a specific commitment the project has already made, so the supply chain work does not float free of the rest of the plan. The standards should be connected to earlier commitments, such as those in a sustainability plan. A supplier table and an evidence section are common, set out in a few pages of APA 7 prose.
How the BU 436 Unit 6 example is put together
The paper begins by explaining why suppliers carry the project's commitments and cites research showing lower-tier suppliers often break standards the buyer never checks. A table profiles six suppliers by tier, product and main risk. A depth section explains why most standards stop at tier 1 while the forced labor standard reaches polysilicon and the battery standard reaches the cell maker. An evidence section lists what proof is accepted for each requirement and why a signed code counts for nothing. A section shows two purchasing decisions the standards changed, with their costs. The final section grades breaches from minor to forced labor and rewards suppliers who disclose problems themselves.
BU 436 Unit 6 rubric: what full points look like
Procurement standards rubrics generally score supplier risk identification, clarity of requirements, justified tier depth, strength of evidence, enforceable consequences and presentation. Risk identification earns credit when each supplier's specific risk to the commitments is named. Requirements score highest when concrete and measurable. Tier depth is judged on whether the student explains why some standards reach further than others. Evidence earns full points when it goes beyond self-declarations to documents and independent audits. Consequences are rewarded when graded, written into contracts and proportionate. Instructors also credit papers that show standards affecting real purchasing choices, since a standard that never changes a decision has not been applied.
BU 436 Unit 6 help: mistakes that cost points
Procurement standards often lose points by relying on supplier self-declarations or signed codes as proof. Another common problem is applying one depth to every requirement, either missing high-risk inputs deep in the chain or burying all suppliers in paperwork. Students frequently name certifications without explaining what they verify. Some set only one consequence, termination, which encourages suppliers to hide problems. Others write standards after orders are placed, when they cannot be enforced. Papers also misstate laws, for example applying import rules to goods that never enter the country concerned. Finally, adapting an employer's procurement terms directly can reveal confidential contract language that a composite case avoids.

BU 436 Unit 6 questions, answered
How far down the supply chain is far enough?
Reach as far as your evidence can follow and say where it stops. Binding a direct supplier is straightforward; binding their subcontractors requires a flow down clause and some way of confirming it happened. Most credible plans require full compliance at the first tier, a passed down obligation at the second, and honest acknowledgment that visibility fades beyond it. Naming the limit is stronger than pretending there is none.
Can I require a named certification from suppliers?
You can require the outcome a certification represents, which is usually the better move. Certification schemes change their criteria, are not available in every country, and can price small suppliers out of bidding. If you do name one, cite the scheme with the date you checked it and add an equivalence clause. Write the requirement so a supplier meeting the standard by another route can still qualify.
Could I adapt our procurement terms for the assignment?
Not the terms themselves. Supplier contracts your employer negotiated, together with the pricing, the audit findings and the country operations data around them, are commercial property and a graded file travels outside the company. Draft the clauses yourself against the scenario, using the course reading and public guidance for shape. Your understanding of what a supplier can realistically be held to is yours to apply.
