Welcome to the hemp coa library at Heartwood Hemp, where every batch we sell comes with a lab report you can open before checkout. This hemp coa library collects the certificate of analysis for every product line we carry, from delta 8 vapes to THCa flower to mushroom chocolate bars. Browse the folders below, open the report, and match its batch number to the package in your hands.

Every report in the library comes from an accredited third party lab. We send each batch straight from the warehouse to the testing facility, so the numbers describe the exact product we ship. Third party lab testing keeps the chain simple: batch goes out, report comes back, and we publish both sides of that story on the listing.

Browse the Hemp COA Library by Brand

The fastest way to use this hemp coa library is to pick your brand and open the matching folder. Each category page links to the reports for the products inside it. Start with the line you ordered, then drill down to the exact batch.

• Delta 8 vapes — potency and purity reports for every pen and cartridge.
• THCa flower — harvest-date reports for every strain drop.
• THCa disposables — batch checks for the live-resin line.
• Azul chocolate bars and Mantra mushroom bars — edibles reports with per-square dosing notes.
• Clean Cart disposables — unit-level verification files.
• 7-OH kratom — potency and purity panels for each lot.

Every folder shows the newest report first. If you buy six items, open six folders and check each batch number separately, because each product deserves its own document.

How We Source Every Lab Report

We order a fresh test for every incoming batch, and we never reuse a report from an older run. The lab receives a sealed sample with the batch ID on it, and the final report lists that same ID. When a new drop arrives, the old report moves to the archive and the new one takes its place.

Accredited facilities follow strict methods, and we still ask for the panels buyers care about most: potency, heavy metals, and residual solvents. Those three appear on every page of this hemp coa library, so the comparison stays fair across brands.

What Each Batch Report Shows

Every certificate of analysis follows the same layout, which makes side-by-side checks painless. The top of the report holds the batch number, the sample name, and the test date. The middle rows list each cannabinoid with its milligram strength. The bottom section shows the contaminant results with a pass mark on every line.

Batch lab reports also carry the lab’s contact details and stamp. Use those details to verify the document online, because a real lab confirms its own result in seconds.

What Every Panel Means

Each report groups its numbers into panels, and every panel answers one buyer question.

• Potency — milligram strength per gram, plus the total delta 9 figure.
• Heavy metals — lead, arsenic, and mercury results in one block.
• Residual solvents — the extraction-leftover check that clean brands pass.
• Microbials — the mold and bacteria pass marks.

Read the pass column first, then the numbers. A report can show a tiny contaminant trace and still pass, because labs allow a safe ceiling for each substance.

How to Match a COA to Your Product

Open the report and find the batch number, then look for the same number on the package near the barcode. Matching numbers mean the report and the product belong together. Different numbers mean you picked the wrong page, so keep looking through the folders until they line up.

New buyers often skip this step, yet it takes less than a minute. Every lab tested hemp product we ship carries a batch ID on the label, so the check works no matter which brand you choose.
