Class 3 flammables, Class 8 corrosives, UN-rated lithium — every 49 CFR document, IMDG classification, and EPA prior-notice filing handled before a single mislabeled SDS strands your container for six weeks.

HazMat entries cleared
49 CFR · IMDG Code · CBP ACE Filing
Since 2018, we've processed 14,212 hazardous material import entries — Class 3 flammables, Class 8 corrosives, and UN-rated lithium shipments — across every major U.S. port. That volume means we've seen every CBP hold scenario, every PHMSA flag, every TSCA notice that slows a shipment. When your commodity arrives at Long Beach, our team has cleared it before.
first-pass acceptance rate
SDS Audit · IMDG DG List · 49 CFR Part 172
First-pass acceptance means CBP reviews your entry and releases it without a hold, exam, or document request. The industry average for HazMat entries is 91.2%. Our 99.4% rate is the result of pre-submission SDS audits, UN number cross-checks against the IMDG dangerous goods list, and 49 CFR Part 172 label verification before a single page reaches the port. The 0.6% that get flagged? We've already drafted the response.
average clearance on Class 8 corrosives
EPA Prior Notice · TSCA Cert · CBP Liaison
Class 8 corrosives — sulfuric acid, sodium hydroxide, battery electrolytes — carry a national average clearance time of 96 hours when filed without specialized HazMat expertise. Our average is 11 hours. The difference is pre-arrival EPA prior-notice filing, TSCA certification prepared before vessel arrival, and a direct CBP liaison who knows our submission record. Your chemical shipment clears before your competitor's has been assigned an exam.
What We Clear
We don't broker general freight with a hazmat add-on. Every shipment we touch is regulated cargo — it's all we do.
Acetone, ethanol, petroleum distillates, and specialty solvents. We handle flash-point documentation, proper shipping name verification, and IMDG packing group assignments before your container is sealed.
Sulfuric acid, sodium hydroxide, battery electrolytes, industrial cleaners. EPA prior-notice filing and TSCA certification handled pre-arrival. Average 11-hour clearance.
UN3480 (standalone) and UN3481 (packed with/in equipment). UN38.3 test summary review, state of charge verification, and IATA Section II compliance for air shipments. We stop the CBP hold before it starts.
ISF 10+2 filing, HazMat entry type 01/03, CBP Form 7501 preparation, SDS audit and translation, IMO dangerous goods declaration, and EPA prior-notice — every form, every time.
Client Outcomes
"We had a container of battery electrolyte — Class 8 — sitting at Houston under a CBP hold. I called ClearanceHQ at 6 PM on a Thursday. They had the corrected TSCA certification and EPA prior-notice amendment filed by midnight. Container released by 9 AM Friday. Our production line didn't miss a shift."

VP Supply Chain, Meridian Chemical Corp
"We import UN3480 lithium cells for EV pack assembly. Before ClearanceHQ, we averaged 22-day clearance windows at Long Beach — the UN38.3 documentation alone triggered exams every third shipment. Now we're at 14 hours average. The UN number cross-check they run before ISF filing has eliminated every exam in 18 months."
Priya Subramaniam
Director of Imports, Voltara Battery Systems
"I coordinate third-party logistics for seven chemical accounts. When one of my clients got a CBP hold notice on a Class 3 flammable LCL, I needed someone on the phone who understood co-load segregation requirements, not someone reading from a checklist. ClearanceHQ knew the SDS deficiency before I finished describing the hold reason."
