The Apparel Sourcing Knowledge Base

Cluster guides

This is a working reference, not a blog: an apparel sourcing knowledge base for the founder or ops lead who now has to get a product made, decorated, shipped, cleared and reordered. If you read one thing first, read landed cost for apparel imports — almost every other decision here resolves into a number on that cost stack.

What this knowledge base covers, and who it is for

Most apparel import resources for brands stop at the border, and most sourcing content stops at the tech pack. These 92 apparel supply chain guides cover the whole corridor at garment level: the duty on your HTS line, what CBP wants in a cotton file, what a blank costs before anyone marked it up, and how to set a reorder point on a 90-day pipeline. One reference for sourcing and compliance for apparel brands, not two.

Every page follows the same rules: numbers carry a source and a date, worked examples show every line of arithmetic, and tariff rates are illustrative of method — verify against the current HTSUS.

What changed in 2026, and why older tariff content is now wrong

US apparel duty law was rewritten three times in twelve months, so any article quoting a 2025 or early-2026 rate is quoting a regime that no longer exists.

The 2026 legal timeline, as of 16 August 2026:

The new tariff is not a trade-deficit tariff. USTR set the rates by whether an economy prohibits and effectively enforces against forced-labor imports, which is why a compliance question and a duty question are now the same one.

Additional Section 301 forced-labor rate by origin, effective 24 July 2026:

What that is worth in cash: on 10,000 cotton knit tees at $4.30 FOB, entered value is $43,000. MFN at 16.5% is $7,095. India's 10% adds $4,300, for $11,395 of duty, or $1.14 a unit. Vietnam's 12.5% adds $5,375, for $12,470, or $1.25 a unit. The origin choice alone is $1,075 on one purchase order, before anyone negotiates a cent of FOB.

Two compliance changes land in the same window. CBP's Forced Labor Enforcement Operational Guidance for Importers, Publication 5560-0526 dated 9 June 2026, runs 89 pages and consolidates 19 U.S.C. §1307, UFLPA and CAATSA §321A into one document. And the Entity List grew by 43 companies to 187 effective 3 August 2026, with 19 additions located outside Xinjiang.

The twelve clusters, and the problem each one solves

Landed cost and duty. Duty is assessed on entered value, not on landed cost, and the difference is money. Landed cost for apparel imports builds the stack; US import duty on clothing in 2026 carries the rates, MPF, HMF and the customs fees nobody quotes you the 0.3464% and 0.125% user fees.

Compliance and customs. UFLPA creates a rebuttable presumption you rebut with documents, not arguments. Start at UFLPA compliance for apparel brands, build the evidence with the cotton traceability file, and settle liability with importer of record vs consignee.

Sourcing operations. Most brands buy through an agent at 5–12% and never see the factory price underneath. Sourcing apparel direct from factories is the operating manual, with what a buying house actually costs you and MOQ economics on why a 300–500 kg dye lot sets your minimum.

Demand planning and replenishment. Every forecasting article stops at the forecast; none connect it to a dye-lot minimum or a 30-day transit. Demand forecasting for apparel brands does, through reorder points when your lead time is 90 days, open-to-buy planning and how to buy demand planning software.

Sourcing origins. Country selection now has a duty component that did not exist in 2024. India vs Vietnam vs Bangladesh vs China does the garment-level math, sourcing apparel from India goes cluster by cluster, and clothing manufacturers in China prices the 12.5% tier honestly.

Blanks and wholesale. A wholesale blank price contains two undisclosed margins over a factory price you never see. The sourcing economics behind blank apparel shows the crossover arithmetic, with spec detail in blank t-shirts wholesale and tier logic in the bulk apparel buying guide.

Manufacturers by product. A tee takes 8.5 standard minutes to sew and a formal trouser 28, on different machines in different plants. Apparel manufacturers by product category maps a range to factory types, with cost builds in t-shirt manufacturers and knitwear manufacturers.

Custom and decorated apparel. "Custom" means two industries with minimums two orders of magnitude apart. Custom and decorated apparel separates and prices both, with method-by-method cost in apparel decoration methods compared and file requirements in apparel design and artwork.

Certifications and sustainability. Brands routinely buy the wrong certificate for the question they were asked. Apparel certifications and what each one proves sets out what each scheme covers and who pays, with detail in OEKO-TEX STANDARD 100 and GOTS vs OEKO-TEX.

Sourcing software. Seven categories share one name, and each owns a different record. Apparel supply chain management software maps them by system of record, then fashion PLM software and PLM vs sourcing platform cover the two purchases brands get wrong most often.

Starting a brand. How to start a clothing brand is the sourcing-first version, with a worked $9,900 first-order budget, alongside how to find a clothing manufacturer and how clothes are manufactured.

Glossary. The apparel sourcing glossary defines 130 terms across ten categories, each carrying the number, standard or threshold behind it.

Start here: six routes into the knowledgebase

If you are starting a brand, read how to start a clothing brand for the budget and the calendar, then MOQ economics so your colour count does not set your buy, then private label vs white label.

If you are buying blanks or custom decorated apparel, start at the sourcing economics behind blank apparel for the $5.91 landed floor, then apparel decoration methods compared for where each method's fixed cost sits, then the bulk apparel buying guide for case packs and size runs.

If you are about to place a first overseas order, this is your guide to importing clothing into the US: landed cost for apparel imports, then Incoterms for apparel brands so you buy FCA or FOB rather than DDP, then the complete apparel tech pack guide so quotes are comparable.

If you are switching away from an agent, start with what a buying house actually costs you, add the two documents that replace it — the complete apparel tech pack guide and AQL inspection for brand owners — then should your brand be the importer of record.

If you are facing a compliance question right now, go to when CBP detains your shipment for the clocks under 19 CFR §151.16, then UFLPA compliance for apparel brands for the evidentiary standard, and read apparel certifications and what each one proves before offering a certificate as a defence.

If you are choosing planning or PLM software, read apparel supply chain management software to work out which category you are buying, then PLM vs sourcing platform and how to buy demand planning software.
