How do I ensure my bulk purchasing with a supplier exchange is compliant with tax and freight rules?

To keep bulk purchasing through a supplier exchange compliant, you want to control how the transaction is documented, taxed, and shipped from the start. Here’s a practical checklist:

1) Confirm the supplier exchange’s legal role

• Determine whether the exchange is acting as:
  • a marketplace/intermediary,
  • a reseller/distributor, or
  • a payment and logistics facilitator.
• This affects who is the seller of record, who collects tax, and who is responsible for shipping terms.

2) Get tax treatment right

• Collect and retain:
  • supplier invoices,
  • purchase orders,
  • tax exemption certificates, if applicable,
  • VAT/GST registration details if cross-border.
• Make sure the correct tax is applied based on:
  • buyer/seller location,
  • product type,
  • whether the goods are taxable/exempt,
  • whether you qualify for exemption or reverse charge.
• If you buy for resale, confirm whether you need a resale certificate or equivalent.
• If goods cross borders, check:
  • import VAT/GST,
  • customs duties,
  • excise taxes,
  • transfer pricing or related-party rules if applicable.

3) Define freight terms clearly

• Use standard shipping terms such as:
  • FOB, CIF, DAP, DDP, etc.
• Confirm:
  • when title transfers,
  • who pays freight,
  • who bears risk in transit,
  • who is importer of record.
• Make sure freight invoices match the agreed Incoterms and are separately identifiable if required.

4) Handle customs and import compliance

• Verify:
  • HS/HTS codes,
  • country of origin,
  • valuation of goods,
  • proper customs documentation.
• Ensure the party named as importer has the ability to clear customs.
• Keep records for audits and inspections.

5) Review local and sector-specific rules

Some products have special requirements, such as:

• food, alcohol, tobacco,
• chemicals/hazardous goods,
• medical devices,
• electronics with recycling or EPR obligations,
• regulated or dual-use items.

6) Build controls into your process

• Standardize vendor onboarding to capture tax IDs, certificates, and shipping terms.
• Require invoice review before payment.
• Match:
  • PO,
  • invoice,
  • proof of delivery,
  • customs entry where relevant.
• Periodically audit transactions for:
  • incorrect tax charges,
  • duplicate freight charges,
  • missing documents,
  • mismatched Incoterms.

7) Use written agreements

Have a contract or terms sheet that states:

• seller of record,
• tax responsibility,
• freight responsibility,
• import/export obligations,
• warranty and returns process,
• recordkeeping obligations.

8) Get jurisdiction-specific advice

Tax and freight rules vary a lot by country and product type. If the volumes are significant or cross-border, have a:

• tax advisor review indirect tax treatment,
• customs broker/freight forwarder validate import/export handling,
• commercial lawyer review the supplier exchange terms.
