For B2B hemp ingredient buyers, the purchase order and supplier qualification process creates the expectation that what you ordered is what you'll receive. The receiving process is how you verify that expectation against reality. In a compliant hemp operation, receiving is not a logistics function — it is a quality control checkpoint with documentation requirements.
This guide describes the receiving protocols that protect B2B hemp buyers at the point of delivery and create the documentation record that supports downstream compliance claims.
Before the Shipment Arrives: Advance Documentation Review
Receiving begins before the truck pulls up. A compliant receiving process starts with pre-shipment documentation review:
COA advance receipt. The COA for the specific lot being shipped should be received and reviewed before the physical shipment arrives. This allows the receiving team to verify that the lot's test results meet your specification requirements before you accept the goods. A COA that arrives after you've already signed for the shipment gives you less leverage to reject non-conforming material.
Lot number confirmation. Confirm with the supplier that the lot number on the shipping documentation matches the lot number on the COA you received. Lot number mismatches — COA from one lot, product from a different lot — are a real risk in hemp ingredient supply chains and should be caught before you accept delivery.
Total THC pre-clearance. Before accepting a shipment, calculate the total THC contribution from the incoming lot using your finished product formula and the COA data. Confirm that the incoming lot will keep your finished products in compliance before the ingredient enters your inventory.
Physical Inspection at Receipt
When the shipment arrives, physical inspection should cover:
Container integrity. Inspect all containers for damage, seal integrity, and any signs of contamination or moisture exposure. Damaged containers are a rejection basis regardless of COA results.
Label verification. Confirm that container labels match the product name, lot number, and supplier information on the shipping documentation and advance COA. Any label discrepancy is a hold condition pending investigation.
Quantity verification. Verify the received quantity against the purchase order. Over-shipments and under-shipments both require documentation and, in some cases, supplier communication before the lot can be accepted.
Appearance check. Visually inspect the ingredient for appearance consistency with the Technical Data Sheet description. Unexpected color, odor, or physical state changes are hold conditions that should trigger a quality investigation before use.
Temperature verification. If the ingredient has specified transport temperature requirements (particularly relevant for terpene-rich extracts that can degrade under heat), verify that transport temperature was maintained. Request temperature monitoring data from the carrier if applicable.
Sampling at Receipt
For B2B buyers with laboratory testing capabilities or access to contract testing services, receipt sampling provides an independent verification layer beyond supplier COA documentation:
Identity testing. A basic identity test — confirming that the received material is consistent with the declared ingredient using HPLC or another appropriate analytical method — provides a baseline verification that can be conducted cost-effectively even without full panel testing.
Total THC verification. An independent total THC test on a receipt sample provides the highest level of compliance assurance at the ingredient level. This is particularly important for higher-risk lots, new suppliers, or ingredients with total THC values close to the container limit.
Retention sample. Maintain a sealed retention sample from every received lot. Retention samples provide the ability to conduct retrospective testing if a compliance question arises after the lot has been used in production.
Documentation at Receipt
The receiving record should capture:
- Date and time of receipt
- Supplier name and lot number
- Quantity received and unit of measure
- Container count and condition
- Label verification confirmation
- COA lot number match confirmation
- Any deviations, damage, or holds noted during physical inspection
- Receiving inspector name and signature
- Reference to the advance COA reviewed prior to receipt
This record becomes part of the batch documentation for any finished product that incorporates the received lot. In the event of a regulatory inquiry, audit, or retailer documentation request, the receiving record is the foundation of your chain of custody documentation.
When to Reject a Shipment
Automatic rejection criteria should include:
- Lot number on physical containers does not match the COA provided
- Container damage that may have compromised ingredient integrity
- Appearance, odor, or physical state inconsistent with TDS description without explanation
- COA results outside your specification ranges
- Missing or incomplete COA at the time of delivery
- Total THC values on COA that would put finished products out of compliance with the 0.4mg container limit
A rejected lot should be held in quarantine, labeled as rejected, and documented with the basis for rejection before return or disposal.
